wus sup evom...
Brief intro:... im not a new member on here but i havent posted much since i registered... i joined this site for information purposes and for a lil bit of eye candy... i sold my evo back in 08 (AS-8mr) couple months before i deployed with my unit over seas. I live in the USVI and there are no dyno/performance shops down here, so my options were extremely limited...I've recently returned back home and purchased yet another AS-8gsr.

AS-8GSR Intro:... the car was bought in ohio with 138k on the ODO... It was owned by a bank manager who drove long ways to/from work and also dewinged it because it was to "rice" for him... and appearently still rides on the factory clutch... i was anxious to see how it would drive/perform with that much miles under its belt... the vehicle was completely stock aside from a TBE and boost guage on steering column.

after my first drive (months after purchase)... i was surprised at how well the car responded and performed... as if right of the showroom floor... no squeeks, no abnormal sounds, pulls hard, shifts well, brakes well... functions almost as if it were new...

INTRODUCTIONS OVER... ONTO THE MEAT OF THE MATTER... O.o

i bought this car with one purpose... to attain 500whp on a dd street car...
my plans on doin this include a factory frame turbo ie... red/black
i only want to purchase parts that i can use in the complete build... (ie... i dont want to buy a act clutch now and then upgrade to red/black and have to buy another clutch later)

my parts list as of right now:
shearer stock frame turbo manifold
gsc s2 cams with beehive springs
ets high flow intake system (purchased)
complete tbe (already on)
exedy twin disk clutch kit
walbro 255lph fuel pump
injector size?

i have several questions:
would this be enough to get me 380whp on e85/350whp on 93?
will my stock ecu be good enough to tune this set-up?
will i have to buy adjustable cam gears for the s2's?
what size injectors should i run now & still be able to keep when i upgrade turbo?

motor as it sit now:


i do plan on doin internal work on the motor (ie crank, pistons, rods) before i upgrade turbos but do you think the factory motor can handle at the minimum 350whp with the stock internals at 138k (assuming they werent changed)?

Any feed back regarding this thread would be greatly appreciated... thanx

 

Yes, factory bottom end can handle 350 awhp. But for 500 AWHP you will need to build it.

Do you have access to E85 Already??

Cam gears maybe, i don't know much about the S2's.

Stock ECU will be okay with the proper tune.(tuner)

injector size will be depending on if you are going with e85.

 

damn thats pretty sick for that many miles. But what can you say the evo is a strong car. Good luck with everything and hope you get to the 500whp ur looking for

 

Uhm I don't know about the evo as much as DSMs but one of the guys at STM just made 500 whp on a stock crankwalker.... So 500 is capable out of a 4g63 on the stock block. As to what kind of fuel and knock control is needed, I cannot say. But if it can be done on an inferior 7 bolt non VVT engine it can be done on an EVO 4g63 with stronger pistons, lighter rods, and access to VVT if it is an 06.

 

i've don my reading on s2's... there more geared toward bigger flowing turbo (3582/86-4088 etc...) but i've also seen reviews about people using them with there factory turbo and getting good top end power out of it... im also in the market for buschurs stg3 head... i havent had a chance to get my hands on e85 as yet... havent made the move to florida (10 more days)... but i would want a slightly more aggresive tune for those times i visit the track...

 

thanx... its not that i dont know the 4g63 is capable of handling that much power on a stock bottom end... what im worried about is the mileage on the motor to put that much more stress on the factory bottom end...

 

Freaking tuners is down or I would like you the car. But I am sure that a 2g DSM probably had higher mileage than your Evo. Although 138k is a lot of miles for an 05. My DSM has 114k and is only 14 years older.

Do a compression check, drop your oil pan, look for metal shavings. If you get good compression numbers and no metal shavings in your pan GO FOR IT! It can take it

I just did the math, and that is 75 miles per day for 5 years. Very high mileage IMO. But still. If your motor is solid and doesn't have bad compression or and kinks it can handle it. It is 90% in the tune. Make sure your not getting knock, or running lean, or running rich etc. Get it professionally tuned and it will last.

 

thanx for the advice... yea i know, i also own a 97 eclipse gst and that only has 135k miles on it... needless to say its been an island car for years so not much long distance driving has been don there...

with that said, does anyone have any opinions on what size injector i should run? would 800-1000cc be too much for the factory set-up... and if its not will they supply enough fuel to hold up with a red/black series turbo...?

 

i would go with a 1000 cc set

 

yea, i know... but i spent 30g's on my first evo, granted it was an 05 with just over 30k on it... but i realized that i wanted more power so, really what the car is capable of stock isnt going to satisfy me for to long... this time around i shopped a bit smarter, didnt really care how much miles the car had on it because it was going to be a complete build anyway... thats when i found this beauty got it for jus a lil over 12g's and i dont regret one penny...

i'll read more on the injectors and see if they will hold for both set ups... i think JMS racing "bumblebeast" have a evo ix turbo running with 1000cc on 22-23psi with e85... i not sure as to how much whp he is pushing out... but at 23psi on e85 he managed to go 12.0 at 116mph...

my first goal would be to hit 11's on a stock turbo...

 

it should hold 350 no problem, but i wouldnt chance it, i had roughly 80k on mine and the motor jus went... making 423whp on fp black... the work was done back in july... before that i had the car running 330whp all day long and never had problems with it... best run with the car was 12.1 ... never got the chance to run the car with the black on it

with that many miles i wouldnt chance your motor and save for a build... then go from there! just my .02 since im currently facing the consequences of high hp on the stock block...

 

if youre going to run e85 in the future then go with some 1200cc-1400cc injectors

 

Mike Rizotti - 9 Sec pass on stock internals

Cory @ STM - Just Hit 500 hp on the stock 7-bolt

Thats 2 people that have done it recently.

 

He wants a 500HP Daily, not a 1/4 mile car. Stock internals will only last so long....

 

thanx for all the replys... i started this thread because my ordering process will start very soon... i do realize the risk of running a higher flowing turbo on a motor with alot of mileage however that is not my intention... before ordering the fpblack i intend on building my bottom end first... has anyone ever heard of AMS's engine rebuild kit... looks really promising... and i think it should hold the 500+whp im looking for with my setup...

So u think i should run 1200cc if im def going to run e85... would they perform well with the stock 8 turbo aswell...? i know i've read that after 300whp the stock inj for the 8's are useless...
