Ok..so I have an evo 8 with map ef3, gsc s1 cams, fic 1250cc bluemax injectors walboro 255 jmfab exhaust manifold along with all the other usual bolt ons..intercooler etc..I can only tuned on 93 oct unfortunately as e85 isn't available by me :-/ so on a dynojet I'm making 421hp and 400lbft..tuned down to 403hp and 358lbft at 28 psi to keep torque under control. So now I want more power..duh lol after speaking to Chris at map I'm thinking of going with the 2.0l but with new drop in rod pistons bearings and main studs, bigger gsc s2 cams and beehive valve springs, and the map ef4. My goals are to break 500whp on 93 while keepin torque as high as is safe to run cause It's my daily driver with occasional trips to the dragstrip. So I'm just wondering people's opinions on if I'm missing anything or if the goal is reachable with current mods and the upgrades I'm talkin about? Also if anyone is running anythin similar??

 

No one..??

 

Why not a t3 turbokit? 500whp is not penny

 

Lol OP you cannot just expect a quick as hell response in 30 mins. Wait a day for people to poke there heads in. If you ask me that combination sounds like it should get you there, or very close to it. You could also go with the Tephra mod ecu and run two maps, one for 93 and one for e85. Then order barrels of e85 or stock up on it when you get chance then run it when you feel its needed. e85 would get you there no problem. Or are you dead set on 93 and nothing else.

 

Well not dead set on it jus I live I jersey and the closet e85 station is only an hour away. We have like 2 in my whole state so 93 jus seems more realistic to me you kno. Forgot to mention I'm goin to run speed density too.

 

I thought the EF3 was good to like 550? Im working on a 2.3L build EF3 on e85 and im looking or 550ish...

 

You don't need an ef4 to break 500 wheel on your setup. Sounds like you need a better tuner and some s2's. What spring are your running in your wg, and add a 3 port to keep that power through redline.

 

MAP lists the EF3 on 93 at 450HP, so maybe without ethanol he does need a bigger turbo

 

Yeah and they listed the ef4 for 650 and I will make over 700 on it. Mind you I do know the limits, that turbo will do 500. He may want to look into a meth kit if e85 isn't available.

 

I'm running the stock spring in the wastegate on my ef3..do you think I should put the bigger spring in?? And I nvr thought of meth and yea can't get a e85 station close enough to make tuneing for it realistic. I'm confident in my tuner. But I feel like if I'm shooting for 500whp on 93oct that doin a drop in set of pistons rods piston rings and all bearing jus seems smart. Budget is a concern but I do want to do it right the first time without doing a stroker or anythin. Machine work on the block isn't in the budget unfortunately lol :/

 

Meth to turn up the boost/power, 3 port ebc to help control the TQ, and a good tune ..403/358 @ 28psi seems a bit low.... im on a old school fp green at 29psi on 91oct i made 407/403.

 

Look into AEM's fail safe for the meth if you go that route. It can certainly be catastrophic if something goes wrong. And if budget is too tight to do it right, than the time to upgrade it is wrong. There would be nothing worse to put down the money to make 500hp like you want into your daily just to have it blow up 2 months later. Then your out all that money, a motor and your daily driver all to be left with nothing.

 

Yea I kno what u mean..that's why I talked to Chris over at MAP and goin to call my shop that I use this coming week..like I said I don't mind saving longer if its goin to be safe and realiable. That's why Im thinkin of building some of the bottom end along with upgrading the turbo and stuff..

 

Put the 5 lb spring in there, that will hold your wg closed longer keeping the power in the car instead of letting it go. I think your tuner needs to relook at the way he tuned the car, mind you though I understand wanting to keep the block together and all but if he put your tq curve later in the rpm range that is why the #'s kinda suffer. With the 3 port you will be able to keep the boost till redline, without having it drop off and that will help keep the #s on the ground instead of wasteing it. Meth as well will help being you will be able to run more timing, but just be safe with it. I have a Labonte kit for my evo and talon and its a really nice kit and it does come with a fail safe.

 

I don't think its a bit low take somethings into factor. He is bleeding off most of his boost after 18 psi, his tuner may be holding back power being he don't want to push the block, he is on s1 cams there is alot of factors going against him. With the s1 cams, those #'s sound right to me. Looking over my old runs of my pump gas runs, I didn't make over 500 till about 30 psi on a single walbro with my ef4 and my mbc, and that is with my current setup.
