The building of one Bad Bish
This thread could turn into a novel of sorts. A "What it takes to build a bad *** EVO" or "How an EVO gave me a list of great memories to last a lifetime". We wanted to do a refresher on the car and how it's progressed over the years. What it's taken to get it to where it is, what we've been through with it. Many people now the car today but weren't around in 2004 to see how it started. I'll make it all as brief as I can, I know I can get long winded when I'm talking about something I love and I do LOVE this car.
I bought a Red 2003 EVO first in March of 2003. Tore right into it, did a lot of our development work on that first car. My brother bought it from me, still owns it and it's a full weight, fully optioned EVO that runs 9.60's at 150 mph today. As clean and nice as it was new. I heard the RS was coming and the news was it was going to be a manual window, no a/c, no sound deadening, no ABS factory race car. I got a tingle in my pants and had to have one! When I picked up the car I was sad to see it came with A/C, all US RS's did but were advertised to not have it. The day I brought it home I was on the hunt to get rid of it. We got the parts from Mitsubishi for the JDM non-A/C version and I pulled it out. Then I removed what little sound deadening the car did have and honest, the quest for a lighter, streetable EVO has never stopped.
I got involved with helping out a not-so-well-known racer at the time, Robert Fuller and our friendship started. Also happy to say it's still going! He found out about an event Car & Driver was doing called the Super Four Challenge and asked me if I wanted to get involved. Hell yes! At the time I was just figuring out the stand alone ECU tuning and my main concern was that the editors of Car and Driver liked how the car drove, idled and performed overall. I thought it was HUGE for the shop to go there and get compliments on the driveability of the car. Robert suggested we use DMS 50mm struts, very expensive at the time. He also suggested the best "approved tire" for the event. There were rules we had to abide by, like tires that were on a list, had to be bought from Tire Rack, all parts used on the car had to be offered to the public. Sadly rules are meant to be bent. At the very last minute a much better "approved" tire became available and "available to the public" meant "Well we are going to release this in the future" to some competitors. We still pulled out a 3rd Place Finish and my tuning got EXCELLENT reviews. The event, to this day, was one of the best events we have competed in and I would absolutely LOVE to be able to do another one. Consider the fact that the car then ran 11.97 on pump gas and now runs 9.72 on pump gas! Things have come a long way! Here are some pictures and some of the article for the Super Four Challenge:
Car & Driver, Super Four Challenge
We had a "20G" on the car for this event. Also note this is far enough back we still had a 2WD Dynojet that we were dyno testing everything on!
20G Dyno Sheet: (430hp or so)
We then got involved with Dr. Kevin Butterfield and the Winged Warrior Event. This has turned out to be my favorite annual event and I refuse to miss it. The event is an all around event where you compete in Autocross, Drag Racing, Slalom and a Car show. Each event is scored individually and the total score of all combined are what determines the winner. This type of event is the back bone of what an EVO is suppose to be and probably why I enjoy the event so much. I have continued to keep a focus on the ENTIRE car and not just building a drag car from my RS. The first Winged Warrior we did our luck wasn't so hot. While we were very quick/fast in the drags, running some low 11's, as soon as we hit the autocross course we dropped a valve from some **** poor valve springs taking the engine out. We were done. It was still fun hanging out and watching the rest of the event. Jeff Oswalt was there (White EVO below) and so was Trent Stanley (silver EVO below). Trent won, one of the skid pad competitions with his car.
Our first Winged Warrior II:
My quest, and I say "my" loosely as I couldn't do it all my myself but it is my passion/project. With Dan my brother doing all the wiring/engine/trans/clutch swaps, Trent and Ted doing the TIG welding, Jarrod and Nick handling sales I couldn't do it all nor get it all done. Anyway, "my" quest to continue to make this car faster, stop better and turn better has never stopped. Before we knew it the car was in the 10.80's in the EVO Stock Appearing Class at the DSM/EVO Shootout. Man there was a lot of **** talking that year from guys who came to the race looking to beat the car on the dyno and the track. Luckily everything went well and the ole RS did it's job in both places.
Here's an engine shot when the car was running 10.80's in ESA:
I honestly couldn't believe how fast the car was and how "little" was done to it. Back then Al Friedman was here at all the races with his EVO and at our shop doing stock ECU tuning every month or so. I told him I intended to build an EVO that I could drive on the street and run 9's with. He told me that I was high on something and it wasn't possible. I thought differently. We developed a cast exhaust manifold to bolt a GT35r turbo on the car using the FP turbine housing. The car laid down 542 whp (how I can remember that is beyond me) and what do you know, it clicked off some 9.90's at 142'ish mph! Those times were run in full street trim with Hoosier QTP's. At the time it was just unheard of, nobody with a real street EVO was running like that. The car of course, just like today, had a full factory interior and looked like it was more or less, stock.
Here's a shot of the car with our cast manifold kit on it:
The quest continued, now I was really excited and thought how easy it was to go 9's. I mean it was kind of a "give me" it was so effortless. I decided to build a few headers for the car. Some crazy stuff and put a half width radiator in the car to do some of it. First I had the turbo right in the center of the cylinder head and kind of out front. That header had a long 4" intake that ran down behind the drivers side headlight. Looked cool but still wasn't quite what I wanted. Next I dropped the turbo down low on the drivers side. Both of these made exceptional power and the car that season dropped down to 9.60's at 150 mph, still on QTP DOT tires. The car was running an FP HTA82 at this point in time.
Here is the header and set up I built when the car ran 9.60's:
Emery at STM was coming on pretty strong around this time and I saw a car or two he built with "forward facing" turbo kits on them. Seemed like a damn good idea to me, so much so I had to do one for my own car. My car has always been and will always been focused on being what I consider a street car. I felt I had to have an air filter so my version of a Forward Facing turbo kit incorporated a custom 4" air filter we had built for us by Green Filters. The car had consistently gotten faster and faster. To my complete amazement we dropped from the 9.60's (from my memory) to 9.11's basically overnight. We went to the 17" motorcycle slicks which were a HUGE help and with the Forward Facing kit and a new turbo, the BR FS635 the times just DROPPED! 9.11 at 157 mph and on pump gas we ran 9.72 at 144.xx mph. At this point I need to thank two other guys. Trent Stanley who use to be our welder here, still my friend, for his driving abilities. He was actually driving the car from the point it ran in the 10's down to 9.60's. I SUCK driving a 5 speed in a drag race and like to put capable people behind the wheel! I also need to thank Kevin Lawson, my friend of about 15 years now, for his driving. He has driven all kinds of my cars over the years and has driven the Bad Bish since the 9.60's to where it sits today of 9.04. Kevin and Trent are both top notch skilled drivers and I'm lucky to know them both and call them friends.
Here is the engine bay as it sat when we ran the 9.11's on race gas and 9.72 on STRAIGHT PURE 93 octane, no additives, no preservatives!

Robert at Forced Performance contacted me and told me he had a turbo that would kick the **** out of the FS635 I was running and wanted HIS turbo on my car. I told him, SEND IT! I got the turbo, put it on and got the car back on the dyno. The power climbed to 680 whp on our dyno in 3rd gear. Response was stellar and so was the curve. Back to the track we went. The turbo, car and driver didn't leave me disappointed! We ran our best time, still to this day, of 9.04 at 159.64 mph! Multiple 9.0 passes that day and all with big MPH. The car had full interior, full BR 3" exhaust, air filter, air bags, door beams, windows all functioning etc. A REAL street car minus the slicks we were running. It was then and still to this day was amazing. This was also done on a standard 5 speed transmission, no dog box, with our Bushwacker Stage 1 in it and a Tilton Clutch.
Here is the 9.0 run.

Well this entire time I had been having more competent drivers behind the wheel. Robert Fuller for autocross/road racing type action, Trent Stanley for drag racing/autocross action and Kevin Lawson for drag racing. My interest in turning was growing because of the "Magnum" our Time Attack car we built, which Robert Fuller drove. I decided to take up road racing with NASA, quickly learned I had some hidden skills and decided to do more of my own driving. I have now driven the RS at Winged Warrior and done well and we have a class called Max Effort at the DSM/EVO Shootout each year. This is a class you have to autocross in and drag race. Your lowest time from each event is added up and the winner is determined by lowest combined time. I'm happy to say I won my class last year, tough competition and close overall times!
Now I have become obsessed with improving the car even further than it has been. I don't know any other EVO that has gone through the development my RS has. I have over 1,000 dyno runs on it, it's been entered in multiple events, has been asked to drag race, stop, turn and look pretty. It's what an EVO is suppose to be. I want to keep taking it to the next level. Now that I am behind the wheel more I have worked on the handling, the braking, the looks and of course still working on the power.
Here are some current action shots of the car as it was the end of this year, 2011:

The quest for power of course has lead to a lot of dyno time, development work and innovation. This part of the thread is about the parts it's taken to get the car where it is today, what we are working on (some of it) and what it takes to duplicate what I consider to be the baddest true street EVO on the planet.
I've went through nearly every engine we offer in the chassis of my RS. Lower compression, high compression, wet blocks, hard blocks, o-ring heads, o-ringed blocks, OEM cranks, billet cranks, small cams, big cams, variety of head work, nearly ever valve spring manufacturer known, COUNTLESS camshafts, 2 liter, 2.1's, 2 liter long rod, 2.3 etc., etc. I believe it is my responsibility to not just sell parts but sell parts I have personally tested, approve of and have run with success. If it doesn't work, you won't find us selling it. If you haven't figured it out yet, I LOVE cars, I am in this because I love cars and I am only going to sell parts we feel work, even if it means passing up a sale. So, with that said. I want the biggest/fattest power and torque curve I can produce. It is of course easy to do this with a smaller turbo and a small turbo is FUN AS HELL TO DRIVE! It is also much easier to drive. Less lag, quicker response, makes a mediocre driver do much better. Now making a fat curve with a big turbo is more of a challenge. I don't like a car that has nothing down low and the "wait for it, wait for it, wait for it HOLY **** THERE IT IS NOW IT'S FAST!!!" feel when the turbo finally starts working. This has lead me to building what I think is our ultimate engine. The 2.3 RPM. The engine was built to give the best of both world's. High horsepower/torque/broad power band AND still rev high enough to hopefully put my car in the 8's. That 9.04 has been a thorn in my side for a few years now, it's funny how .05 seconds can run your life! With this new engine we have fought traction more than ever and the motorcycle slicks, after a blow out at the top end of the track, just became too dangerous to risk anymore. We also got away from the $5,000 Tilton clutches and have found it difficult to power shift he car, with it spinning most of the time and get good clean gear changes. Anyway....

The crank scraper helps to keep the oil in the pan where it belongs. It is designed to work with a standard 2 liter build but with some grinding you can make it work with the 2.3, which I have done.

Our head has been on more 9 second EVO's that any other out there. It's what I believe in and what I run. Our black car ran 8.80's at 172.74 mph with this same head.

Valve float is a serious issue as I said earlier, we lost an engine because of it. It sent me on a testing spree to buy up and run most of the springs offered on the market. We have found what we believe works the best.

When the boost gets really high and you have to keep those high cylinder pressures sealed up it's hard to beat L19's. Up to 40 psi with some good tuning the standard ARP's we offer also do their job quite well.

I mentioned we tested a lot of cams. When I say a lot I will point out that I have done as many as four cams changes in a single day on my car without unstrapping it from the dyno. I have found cams that make more low end, more top end but never found a cam that makes a fatter over all curve than our BF272's and it's what I'd venture to say have also powered more EVO's to personal records than any other single cam on the market.

Oh boy......intake manifolds. Drama, controversy, disaster, lost friend ships, ruined careers..........no other topic has caused more problems than this one. Bottom line is the stock intake manifold works. Yes there are SOME that make more top end power, we even built our own here. NONE make more power under 5500 rpm than a stock ported manifold, NONE. I have also yet to find one that was beneficial on an EVO if the car is under about 550 whp. I found some JDM stock EVO8 intakes that had less crap on them than our US market EVO8 intakes and bought them up. With a great port job on them it's what I run on my car, just because it looks cleaner than the stock EVO8 intake. No performance advantage over the EVO8. My car has made 725 whp at 33 psi of boost on our dyno using the stock ported intake and my power curve is INSANE with it on the car.
INTAKE MANIFOLD:

Along with the intake comes our ported stock throttle body. We bore it out and put a high quality larger 65mm plate inside along with new seals and clean them up nice. This is also what is currently on my own RS.

Engine mounts, this is a great way to hold the drive line in position and does actually help with both weight reduction and breaking parts. Down side is anytime you make something more rigid you do get some additional vibration.

Weight savings is something that I am addicted to. There are a lot of free things you can do to make your EVO lighter. There are also some that aren't free that not only drop weight but help the driveline live. Our front center member drops 6.5 pounds of the front of the car, includes a nice urethane front engine mount and looks great.

If you are running high boost and expect the car to run clean you are probably going to need an ignition. The first coil on plug ignition for the DSM and EVO's were developed here first. Ours have proven themselves time and time again. The mini battery kit was done here first too and drops 20 pounds off the nose of the car.

There is no other fuel system upgrade required for your EVO and there are no other products on the market that have been as used or successful as ours. This is enough fuel for 1,000 whp.
I've went through nearly every engine we offer in the chassis of my RS. Lower compression, high compression, wet blocks, hard blocks, o-ring heads, o-ringed blocks, OEM cranks, billet cranks, small cams, big cams, variety of head work, nearly ever valve spring manufacturer known, COUNTLESS camshafts, 2 liter, 2.1's, 2 liter long rod, 2.3 etc., etc. I believe it is my responsibility to not just sell parts but sell parts I have personally tested, approve of and have run with success. If it doesn't work, you won't find us selling it. If you haven't figured it out yet, I LOVE cars, I am in this because I love cars and I am only going to sell parts we feel work, even if it means passing up a sale. So, with that said. I want the biggest/fattest power and torque curve I can produce. It is of course easy to do this with a smaller turbo and a small turbo is FUN AS HELL TO DRIVE! It is also much easier to drive. Less lag, quicker response, makes a mediocre driver do much better. Now making a fat curve with a big turbo is more of a challenge. I don't like a car that has nothing down low and the "wait for it, wait for it, wait for it HOLY **** THERE IT IS NOW IT'S FAST!!!" feel when the turbo finally starts working. This has lead me to building what I think is our ultimate engine. The 2.3 RPM. The engine was built to give the best of both world's. High horsepower/torque/broad power band AND still rev high enough to hopefully put my car in the 8's. That 9.04 has been a thorn in my side for a few years now, it's funny how .05 seconds can run your life! With this new engine we have fought traction more than ever and the motorcycle slicks, after a blow out at the top end of the track, just became too dangerous to risk anymore. We also got away from the $5,000 Tilton clutches and have found it difficult to power shift he car, with it spinning most of the time and get good clean gear changes. Anyway....

The crank scraper helps to keep the oil in the pan where it belongs. It is designed to work with a standard 2 liter build but with some grinding you can make it work with the 2.3, which I have done.

Our head has been on more 9 second EVO's that any other out there. It's what I believe in and what I run. Our black car ran 8.80's at 172.74 mph with this same head.

Valve float is a serious issue as I said earlier, we lost an engine because of it. It sent me on a testing spree to buy up and run most of the springs offered on the market. We have found what we believe works the best.

When the boost gets really high and you have to keep those high cylinder pressures sealed up it's hard to beat L19's. Up to 40 psi with some good tuning the standard ARP's we offer also do their job quite well.

I mentioned we tested a lot of cams. When I say a lot I will point out that I have done as many as four cams changes in a single day on my car without unstrapping it from the dyno. I have found cams that make more low end, more top end but never found a cam that makes a fatter over all curve than our BF272's and it's what I'd venture to say have also powered more EVO's to personal records than any other single cam on the market.

Oh boy......intake manifolds. Drama, controversy, disaster, lost friend ships, ruined careers..........no other topic has caused more problems than this one. Bottom line is the stock intake manifold works. Yes there are SOME that make more top end power, we even built our own here. NONE make more power under 5500 rpm than a stock ported manifold, NONE. I have also yet to find one that was beneficial on an EVO if the car is under about 550 whp. I found some JDM stock EVO8 intakes that had less crap on them than our US market EVO8 intakes and bought them up. With a great port job on them it's what I run on my car, just because it looks cleaner than the stock EVO8 intake. No performance advantage over the EVO8. My car has made 725 whp at 33 psi of boost on our dyno using the stock ported intake and my power curve is INSANE with it on the car.
INTAKE MANIFOLD:
https://secure.buschurracing.com/cat...products_id=80
Along with the intake comes our ported stock throttle body. We bore it out and put a high quality larger 65mm plate inside along with new seals and clean them up nice. This is also what is currently on my own RS.

Engine mounts, this is a great way to hold the drive line in position and does actually help with both weight reduction and breaking parts. Down side is anytime you make something more rigid you do get some additional vibration.

Weight savings is something that I am addicted to. There are a lot of free things you can do to make your EVO lighter. There are also some that aren't free that not only drop weight but help the driveline live. Our front center member drops 6.5 pounds of the front of the car, includes a nice urethane front engine mount and looks great.

Something so simple but so overlooked. As the rubber oring dries out on the stock dipstick or crankcase pressure goes up from high boost levels the dipstick has a tendency to pop out. This one was Dan's idea and we've sold a lot of them. Great way to prevent a fire!

I think in order to become a believer in certain things you have to experience first. Brake pads are one of those things. Stock the EVO brakes are awesome........right up until the time you drive an EVO with some quality, proper brake pads on it, then you realize stock the EVO brakes SUCK. I was woke up to this while road racing at Mid Ohio. I can tell you, upgrade your pads, you will be amazed!

OK so the RS doesn't come with ABS. After learning how ridiculously good the brakes become with a pad upgrade I also found I was unable to control the lock up of the tires when I was on the brakes hard. To help with this we built a manual brake conversion kit. The kit drops close to 10 pounds off the nose, cleans up the engine bay and keeps you from locking the brakes when you don't have ABS. The car will stop just as fast and hard as it will with power brakes but requires more leg input.

I love the idea of staying in the seat so you can actually drive the car. Being tossed around the car when you are autocrossing doesn't make you a better driver. It's also dangerous. There were other harness bars on the market but they all were unsafe to the back seat passengers. I came up with a quick release bar that can be removed in about minute. This allows you to use it for track use and then when you have to haul your kids to school you can pop it out quickly. Not that I am endorsing it as a roll bar but........there have been cases of a tech official taking a quick peak at the harness bar and harnesses and guys have slid through tech with it at the drag strip.

Hungry for the 8's is an understatement. This post is kind of what has been with the car. The new build will be released, hopefully very soon. We keep running into delays because of the development work required for what we are doing. We've had to custom machine a lot of parts, some of which we are still waiting for, electronics etc. It should stop faster, turn better and accelerate faster than it ever has.
Our BF272's are very good tcomp, but we have a really bad *** top end cam on our shelves now that if anyone isn't too worried about low/mid range are much better off with, like 50'ish whp peak and gains after 5500 rpm.

Nice break down David, I must say the Buswacker trans is awsome so far I got 1k miles on it and 540 ft/lbs in her with no issues and the BR SD Catback made good power with just bolting on. Thanks David for all the support for the community.
