Sup everyone my car is basically still stock, i have a hks bov, thats pretty much it for the engine. I was thinking about getting the Apexi SAFC 2 and a HKS EVC 5, are these good mods for a stock evo? Or should start with a different route, I was also thinking about getting the basic Fireball through the mail dyno flash. I have heard great things about it. Any help you can give me would be great.

 

Stick with the basic BPU's (Basic Performance Upgrades) like an exhaust, intake, MBC, etc.

Install a boost gauge asap. You will definately want/need one stock or modified.

You can dynoflash now or later, it's tuned to your level of modification.

Hope that helps...pm me for specific part suggestions.

 

i've heard mostly negative things about aftermarket intakes

 

How long have you had the car? The best suggestion I have for you is to leave it stock until its no longer under warranty.

But as the previous poster said, stick with the basic performance upgrade stuff, give some thought to what you realistically want out of your car, come up with a realistic plan and try to stick to it. It will make your decisions alot easier, plus you won't be swapping parts several times before you find something that you want to stick with.

Although I love working on my car, I've been through quite a few generations of parts and it definitely was a waste of money in some respects. Not a waste of money because the parts sucked, but because my needs changed.

Learn as much about the capabilities of the car, and the products available.. but stick with the basics.

1) K&N Drop in air filter (Stock airbox)
2) Boost gauge
3) Cat back exhaust system

Those will have a decent effect on performance, and NOT void your warranty.. Its also unlikely that you would want to upgrade the exhaust again except for a high-flow cat an downpipe, which can be added later.

All I can say is if your REALLY **** about quality and hearing squeaks and rattles, or noises bother you.. I strongly suggest you not modify the car until it gets a bit older..

 

I will mod my car following these steps:
1. kN drop in air filter 2. Ralliart spark plug wires 3. Ground system 4. hyper voltage system .Racing spark plugs 5. MR type blow off valve 6. Ralliart ECU 7. Ralliart cat back

I think that these mods are pretty much safe and just add power and quality to my car.

 

If you are bound and determined to modify your car, I'd advise you very strongly (from very expensive experience) to first spend the time and money to find out the exact condition of you car as it is.

There is no assurance that your stock car will respond well to any modifications. If it's like my car, you'll spend many thousands of dollars and endless frustration and still have a slow car with lots of problems.

1. Make sure your engine is in very good shape compression wise
2. Make sure it can take timing and fuel adjsutments without knocking

You'll need to take it to a dyno and get a base line whp and tq number. Also, beg borrow or steal an SAFC and a MBC. With these and the WBO2 sensor and the dyno, you can start to see how the engine responds to fuel adjustments and boost increases.

I know this sounds expensive and a lot of work, and it is. The alternative could be much worse. I've sunk over $8K in my car and I have basically a messed up car. Beware of tuners pushing you into tons of mods and promises of great hp increases. A lot of guys are very good at selling stuff and bolting **** on, but they are not real tuners or mechanics. When the problems appear, you are suddenly on your own and they'll drop you like a hot potato. I guarantee you that they'll try everyway in the book to get out of the mess and leave you with it. It happens all the time.

If you are an experienced mechanic yourself, you can go ahead and start everything since you'll be able to fix it yourself. I suspect you are not a tuner or expert mechanic since you are asking questions here so I'll advise you to do as I suggest and establish where you are before you do anything else.

BTW, I saw a basically stock EVO with intake, exhaust, SAFC and boost controller run in the 12's at nearly 110 mph (the driver is very good!)
I've yet to get into the 12's and I have just about every mod short of stoker kit and upgraded turbo.

good luck

 

Yeah, I ran a 12.42 with those same basic mods.. Its not impossible, but you have to be certain your car is healthy.. Very good point Silver.. I still stand by my "leave well enough alone" attitude.. If I could resist the urge to modify, I'd have more money in my pocket, a warranty, and not be addicted to this beast..

 

i think thats one thing we cant do here in the u.s. but there's always a reflash but i do like those pre-tuned ecu's like kansai's but they only work on the jdm evo's and not good with our 91 **** here in cali.

a turboback would be a good mod to start with then en ebc paired with an afc just in case you start getting addicted with more boost.imo tho open element intakes are only good with tuning since if you get them now w/o any tuning it will just throw the car off and you'll be better off with a drop-in instead.

 

I'm just starting to mod now... I've got a k&n drop in and ordering BR 3" turbo / mbc next week.. then ill probably do plug wires and a grounding kit.

 

I agree with SilverEVO8!

I had many problems with tuners. Be carefull.
This is the reason why I'm looking for Ralliart parts. I trust on a company that knows my EVO since a long time ago. Just to think: Why Ralliart cat back is a 2,5in instead of 3 or 3,5?

Good luck

 

There's lots of ppl out there with horror stories to tell..... The problem is they get shouted down by ppl who are happy with their products and defend their tuner/friend to the end. Others are very happy with placebo effect mods....
I say go ahead with exhaust and intake mods if you want, they are not likely to hurt anything except your wallet

I still would very strongly suggest spending the first money in the dyno testing of the car with at least a boost gauge and MBC (cheap thing that). If possible borrow beg or steal the SAFC or equivalent to see how the car reacts to higher boost and fuel adjustments. Anything else done before this is likely to be a waste of time and money. Many EVOs do not take well to mods..... I've seen many EVOs run high 14's at under 100 mph, even those with cat-back exhaust and drop-in filters and even reflashes or piggy-backs...... Let the buyer beware

Please spend your money and effort up front to find out exactly where you stand with your car. I'd guess what I'm suggesting could be accomplished by as little as a couple of hundred bucks or as much as $600 or $800 if you buy the SAFC.... That's still only one tenth of one twentieth of what you could drop to gain a measly 50 to 70 whp.... That much money could buy you a very fast drag car already set up.......
