As the title says im in need of advice on what turbo and supporting mods i should buy for my FD.I plan on making around 400-450 hp and around 350 torque.I plan on my fd being used for drifting and autox.It will also be daily driven 4 months out of the year(dont know if tht matters).As far as turbo characteristics go i would like quick response and low end power as well.Any help is appreciated.

 

gt35r will get you there and have good response.

 

450 rw ROTARY hp requires 60 lbs per minute of air. here are the turbos that fit your needs ordered as to average area in square inches of compressor wheel.

HTA 3586 (Forced Performance).................6.839................ ...5.171....................76

you use 400-450...

400 might be the popular ball bearing GT3582r or the journal bearing GT3574 with it's larger rotor friendly turbine wheel

450 might be more the TEC300/R85/BWS300-61. (compressor 61.5 X 84.7, turbine 70.8 X 79.8)

If your more serious about autoX with some street use I would stay focused on the 35R possibly with a TiAL 1.03 rear it will get you over 400whp with excellent response and is a very clean and simple setup. If it is more or a street car with the occasional track event a 3574 would be a nice choice. As would a 60/62 (a bit small but good for autoX) 61/65 or 62/65 for street.

hmmm everyone seems to like the Gt35 series.I think thts what im gonna go with but what do all the numbers mean after the Gt35 mean.different bearing,bigger turbo?Btw what do the different bearings do?

 

3582R (Garrett designation) is a 35R in 3582R the 82 is 82mm exducer (major) on the compressor. 3574 is a A-spec turbo it mates the 35R compressor wheel with a oversized 74mm turbine wheel versus the 68mm turbine wheel Garrett puts on it.

alright i got it i think,so basically the 3582r is just a hopped up 35r?

 

No sir a 3582 is a 35R a 3574 is a hopped up 35R You'll make more power and pretty much keep the same response roughly.

and much cheaper with less backpressure on your engine. the 3574 is an awesome turbo, rotaries love the p-trim!

 

500R-SP for your power goals but if you want response for autocross then 35r.

ohhh i gotcha
what sites would you guys recommend to buy these turbos from?

 

So im in the same boat want 450-500whp and im looking for quick response, i know for sure im set on the 35R series but what is the best one for my build and also what size injectors and fuel rails would i need for this kind of a build?

 

1600 secondaries with a Denso fuel pump rewired directly to the battery with 10 gauge wire.

What's the estimated cost to go from stock to GT3574?
All that's done so far is intake, IC, ECU, downpipe.

 

I'd prepare at least 5k minimum to do it right considering the GT3574 is a lot cheaper then the ball bearing version.

If your after 450-500whp the 3574 will get you there easier than the 35R. Suggested injector sizes needed for that HP range would be 850-1680's


Let's say ECU is good and IC is good, You will need fuel system, clutch, single turbo. I'd say between $4 and $5k sounds about right give or take depending on choices made.
