Default Thinking about an FP Green for my 04 STI Few Q's

This would be my set up...tell me what you think and/or what I'm missing. I need suggestions for injectors (was thinking about having my stock one modded by perrin for like $200 or so). What else do I need?

04 STI

FP Green Turbo
STI stock tmic
K&N short ram intake
Stromung flat flange DP
Stromung mid pipe
Espellir cat back (3in)
Utec
Wallbro Fuel pump
Injectors (needed...which ones?)


Thanks in advance to everyone. I have searched and will continue to but this is my exact set up.

The stromung midpipe and espellir catback are redundant. The catback includes the midpipe and axelback portion of the exhaust.

Modded stock injectors are fine, just get them flow tested and cleaned.

You also don't need the intake. Some tuners say you will need a larger MAF (which you will need to tune for) but you don't. Just make sure you get a good tune.

It's not redundant.

In the Subaru world, people refer to the second half of the downpipe as the "midpipe". Most aftermarket downpipes are complete (e.g. Perrin, Helix), but some just replace the first half of the downpipe, like the Stromung piece. The Stromung "midpipe" is needed to complete the downpipe.

I have always referred to the midpipe as the portion between the cat and the axel. Now I feel like a dope.

I have always called that the midpipe, too. I think people were just naming the exhaust components as they were called out in the Subaru factory service manual...?

yup. Because most downpipes replace the downpipe and the "mid pipe" catalytic converters and the part remaining is the "cat back". At least this is how I understand it. If the downpipe replaces the downpipe catalyst only is called a shortie downpipe.

perrin modified injectors are fine... make sure you get a turbo inlet hose as well (samco or perrin). i had a similiar setup with the green. i liked it a lot. since it appears you're going with the internal gate, try to get the 8cm housing, if you can find one.
i had bad luck with the stock airbox so i'd stick with your k&n for now.

who will be doing your tuning?

XX-Tuning in Hartford will be doing the work...I'm just doing some early research on what I will need. Any idea on where to find a FPG with the 8cm housing for a good price?

Not sure if it matters or not but what about the SZ49 inplace of the FP green? I know that they both have 49lb wheels and all but isn't the SZ a better turbo? Plus deadbolt has free rebuilds for life. Turbo inlet hose is not on the list.

both fp green and deadbolt sz49 are great turbos. you'd have to call or email forced performance to see if they still offer that housing. i would look into getting a perrin ecbs to help prevent possible problems controlling boost.

Stainless steel oil line from fp or other vendors. Big maf for race gas use and if ur on a budget u can still use the factory turbo inlet, just got to grease it up and muscle it in.

Go with a set of modded stockers, then find your nearest drag strip and go do this.

My STi

I had just about the same setup as you when I made that pass.

12.05 is nice. Was that on race gas or pump or something else?

Can you provide a list of mods?

cheers

Only problem is that my car with me in it and all the sound deading weighed in at 3600 lbs...that tends to slow you down a bit
