i just got my evo it was stock im trying at at have 400 awhp on a stock turbo. so far i brought injectors ETS intercooler full race manifold stock icp springs retainers and injectors. what other supporting mods do i need

 

What do you mean when you say you have an Evo 8.5?

400awhp is capable on the stock 9 turbo if you have that. Do you have upgraded cams? What is the full modification list? You will also need a fuel pump, bov, intake, turbo back exhaust, lower intercooler piping, and a tune.

All answers to your questions are available in a ton of other threads just like this...keep up the search.

 

Cams GSC S2's preferably.

 

the part list so far is
turbo back exhaut
intercooler 3"
bov
dual springs
ti retainers
pro stock mani coated
revolver cams
my next buy is FPR, fuel pump, and gauges

tune once it all on the car

 

No need for FPR until you get a dw 320 or wal. 400 and rewire it. Put money some place else. Now are you looking for 400 whp on pump on race gas/e85? Not sure what jersey has for pump, 93? Well you can get close to that goal on 93 and def. make it on E85 but it's just a quick spike then a RAPID drop off. That's just the nature of that turbo.

 

Get an o2 housing, a lower intercooler piping, Evo 9 turbo, and if u have access to e85 you will see 400 easily

 

yeah jersey only has 93 not e85 hopefully i can move somewhere that has e85 so with a walbro 255 i wont need a FPR so ill find a good icp set up. how do everyone like the small battery setup im plan on getting a double din radio should i just relocate my battery to the trunk or will the small battery hold up for a while?

 

Correct you will not need FPR until you are running a rewired larger fuel pump. Ets lower ic pipe is very good. I use the full ets kit and mini battery. Should last okay unless you throw a huge bumpin sound system in. To lower amp draw on it I will make sure all accs. are off before starting. Stuff like AC/heater radio etc..

 

im not planing on not huge system i had a double din in a vw i owned and the wife likes to watch movies while i drive so im planning on getting it again. any other performance mod i should get im planning on build the block this winter and a shep trans next spring.

 

You really dont need a manifold Stock manifold is best for stock turbo you lose spool

 

Didn't see it in your list but. Injs. If you hit 400 on 93 it's not going to be a sustained 400. it will peak for a few 100 rpm then rapidly drop off. 9 turbo does not flow enough to support that level for very long.

 

My mods are in my signature take a look. I made 400HP on a mustang dyno. You will definitely look into a different fuel then pump gas though.

Also clutch, depending on what you have and if yours is fresh still.

I made 400 pretty easy with my mode in sig, but most importantly e85. But as they said its just a quick torque spike as the rpm's climb u just plain run out of turbo (hate stock turbos). I won't have that problem in a few months with my new built block and pt 6262
