Default big turbo decision

hey everyone, i'm deciding to go big turbo or i should say bigger turbo with my 2004 sti. i'm new to the subaru world considering i'm a chrysler mechanic, and i was always a vw guy. i currently have turbo xs front mount, turbo xs down pipe 3", turbo xs axle back exhaust and cobb tuning stage 2 flash. (i was waiting to get my car custom tuned when i got the big turbo). i read a lot of different turbo but from what i have now and trying to get max power on stock internals for now what turbo would be a good decision for my car. a buddy says the fp green and i've talk to the guy from AMR and he suggests amr. if anyone could help me out or share your results with simular set up please let me no, thanks a lot everyone!!

I'm happy with my FP Green on stock internals. I'd stay away from the AMR just from the things I've heard about AMR and their turbos, but I don't have any firsthand experience with their product.

Here's my setup and dyno, 350whp/346tq:

http://forums.nasioc.com/forums/show....php?t=2421905

I've driven about 2000 miles with this setup so far, some of it very hard. I have no negatives to report and so far the engine is fine. I will warn you that upgrading your turbo without upgrading your pistons will probably lead to an engine rebuild somewhere down the road, but a safe tune will go a long way into warding that off.

Plenty of people on here have gone with Blouch turbos. If you poke around Proven Power Bragging you'll be able to find some builds that can point you in the right direction.

Depends what you want from the car. It is a lot of time, money, and hassle....so if you enjoy the car in stock or stage 2 form, keep it there.

Internet asshat advice: Install a Garrett GT60.

Cool guy internet advice: Unplug from the internet and call 717-865-3276 on monday morning. Tell them your car, mods, WHP goal, and budget. They will discuss the options and give you a recommendation. Buy whatever they recommend from them instantly. Then you will be assured with a 98.4% rating that it will be the perfect turbo.

I once had this decision myself, heres my conclusion:
To do it the way I wanted to, in my head, it was going to be around $3,000.
For that price, I could buy, and build a 240 that would be the same hp level, if not more powerful, and the most important part, reliable.

I don't know what you heard about AMR's turbo but they make great parts and their turbos are awesome. The T60R is definately the best for the money.
Here is a road dyno on a 2.5L 10' STi, 272 RCM cams, E85 gaz :

Boost : 14,5 psi @ 3300rpm which is great on FMIC


Dyno bHp (E85 gaz) :


Still have to try their SLR series turbo which should arrive very soon I hope ...

That's the thing I'm going back to school for commercial diesel technology. Just wanted to go a little bigger so I don't have all this turbo lag and still be able to keep my motor safe, so I would like to stay away from big turbo upgrade. My buddy runs precision ball bearing 5757 I believe awesome turbo but i don't want to rebuild my motor after a year of driving it. AMR prob going to go the AMR side. Product seem good a ton of friends use then as well and have made very decent power. I'm Also considering to speed density as well. Still doing some research as to what I need. I've heard sensor, wire harness, and block off plate. I found the 4 bar sensor and also the block off plate. Anyone else run this way?

Have a friend with an evo that got his car tuned at the shop in ct and made great power. Don't no much about evo but I've heard pretty good things about the shop. There's also another place too that I can't remember the name around the Putnam county ny area. Heard a lot of good things about fp green too. Let me no what everyone thinks. I'm open to anything.

Bigger turbo for less lag

If you want less lag, and do not want to build your block, ditch the FMIC. Trust me, I have been there...on both sides. VF39 with FMIC sucks balls, and a 30r/ 50ish PPM turbo requires a build if you want to get anything out of it.

Most of the turbos you mentioned are way past the line where you should build...

You have "lag" with the stock turbo Very few turbos spool faster than the tiny VF turbos (short of downgrading to a TD04).

You need to figure out what you want out of the car: awesome daily driver with lots of low rpm torque (18/20g size), daily/strip warrior (30/35r size), drag only (40r+ size)... The type of gas you'll be running is also important (pump vs. E85/race gas). There are different turbo choices for each scenario.

By the way, you'll need, at the very least, injectors and a fuel pump if you upgrade your turbo. Depending on how far you go, you'll also likely need a bigger MAF.

Start saving for your built block, too. EJ motors have shortened lifespans at 350whp and up. Even with a perfect tune, the pistons are on borrowed time.

If you want to keep the fmic, go for it but, your going to have to put more money into your car to have less turbo lag. Otherwise, get rid of that fmic and get the stock tmic or a 08+ STi tmic... I would go with a FP Green or a TD05 20g with supporting mods (bigger injectors, fuel pump, cai, inlet) I would also add headers, and possibly a lightweight crank pulley if you keep that fmic.
I had turbo lag with my Tomioka Racing TD05 20g, added a crank pulley and now I dont feel a lag.
Also, keep in mind, when you add more power with stock internals, you're going to have to build a motor later down the road.

Stop lying. You did not call 717-865-3276 which proves you are not open to anything and that you have your rudder jammed over on FP Green and are looking for someone to justify a FP Green. Now go buy an FP Green and leave us alone. People like you who come on these forums are the reason why people like me get all honked off around here. Here's a pro-tip: do not be dismissive of advice when its given due to your asking.

Agreed. If you want REAL advice, call the pros. It appears that you are looking to justify what you already want, or are seriously going to take the advice of a bunch of internet dudes. Not good for you or your car if the latter is true.

I am running a full built motor, Cosworth intake, big FMIC, big valve heads and a GT3782 turbo. I don't start making power till 5k and redline at 9800. I would suggest twin scroll ball barring turbo, maybe a GT30R with a true twin scroll designed header for a quick spool. I also have #10 fuel lines, Aeromotive 1000 external fuel pump and 1600cc injectors to support the boost.
