I need your guys opinion my budget is around 5k and wanting to get about 400awp on 91. What do you guys think? Full mod list will help

 

full boltons, injectors, fuel pump and a tune on E85.. You'll be close to there. You can also send ur 9 turbo to FP, for them to build it. I'd say if you buy used parts you can get all that done for around 5k and possibly make even more than 400whp.

 

Turboback exhaust, cams, intake, manual boost controller turned up to about 24-25 psi and MOST IMPORTANTLY A TUNE! That should net you roughly 400hp depending on the dyno. You will need a fuel pump and injectors as well.

 

Fuel pump: Walbro 255 or DW301 $100-$150
1000cc injectors, around $500
Garrett GTX3071R turbo $2200
FMIC: AMS, ETS, or Greddy $900-$1000
Cams: Kelford 272/272, is around $600
ARP head studs, $130
MBC: Forge, Halman, or Grimmspeed, $100
You would need an uprated clutch kit, the Exedy stage2 metallic clutch is around $800. I'd recommend you install a twin clutch kit such as the Exedy HD, around $1700
In case 91 fuel is the only fuel you have available then I recommend you install a water/meth injection kit. AEM water/meth kit is around $500

 

You'd need at least a full back exhaust. O2 housing back. MAP performance has some good exhausts. O2 housing, downpipe, cat delete/high flow cat, cat back exhaust. That would eliminate the major choke in the exhaust. ~$1000 or more

You would need injectors higher than 850cc for gas and over 1000cc for E85 plus a walbro fuel pump.~$600 or more

Get a JDM MAP sensor (3 bar MAP sensor) so when they tune your car you can have boost control through your ECU so your engine will be safer with boost error correction. ~$100

You'd need a good clutch too. And the install can be a pain. ~$1000 or more with install

You'll also need new spark plugs before the tune to get the most out of it and then probably after just in case they get overly rich. But usually you'll be fine with the plugs from the tune. ~$Varies $400-$600 for tune

This would be between $3-4k. You can get a high flow air intake which is usually couple hundred.

If you get slightly larger intercooler. I think 3-4" intercooler should fit with no problem stock without much trimming. You'll need new lower piping for that which could run up to another couple hundred. ETS has a good package but it will be around $1000.

All this should get you to 400hp or more easily and you'll have some room for improvement if you wanted to add cams to your car or better turbo. With the larger intercooler you should see better spooling than stock too since there should be more air flow. This is pretty much where I'd start. Worry about a bigger turbo later down the road and get to know the car better with that power. Then you'll have to upgrade suspension parts for better handling.

 

gsc s1
bbk full port
id1000s
speed density
stock intake and exhaust manifolds
hard pipes
ams cooler
3 inch exhaust..

400 whp is easy

could get close even with the stock 9 turbo

 

This. It will get you there.

Profit from lucrative underground street racing scene!

 

 

Plus snake eyes and undercarriage neon lights should give you another 10 HP lol

 

Converting to E85 will get you to 400whp on 91..... truth.

 

I am aiming for reliable 400 hp and this is my ideal mod list

CBRD BBK full ported
1000cc injectors
GSC s2 cams
MAP o2 dump
full AMS TBE
ETS 3.5 intercooler and ETS UICP and LICP
255 lp
TUNE + on 93 octane

Plus other supporting mods but I am to lazy to list them

after that I am gonna rebuild and strengthen the internals

 

cams injectors exhaust and fp green

 

Is this a joke?

 

What size turbo?

This was my model build:
