Hey lads I currently have a full milltek system and k&n drop in filter and ecutek remap from Pat Herburn on my 2006 sti spec-c. My car goes very well but I would like some more power hoping to get the car up closer to 400bhp the powerstation stage 4 spec loooks quite good and I am wondering does anyone have it done to their cars.

Or if anyone could advise me how to get closer to 400 please do tell

Uprated Walboro 255l Fuel Pump, 650cc Injectors & MD321H turbo and another remap should see you at the 400bhp mark.

Whats the spool like on these and will I have to change my manifold to run it seeing as the spec c runs a twin scroll turbo?

Sorry funnyclub, forgot you were running a twinscroll turbo. You can always ask Mark@lateralperformance if he does a twinscroll version of the 321H, but I must say I haven't heard of one.

Speak to forum user 'gussy'. He has the stage 4 package on his Spec C Type-RA and is very happy with by all accounts. I'm sure I remember him saying that there was additional 200rpm or so difference in spool.

You may have to give your turbo to Power Station or someone like Turbo Dynamics for them to fit a larger Garrett core. Id say it could be expensive.

If you go to a single scroll you only need a downpipe and single to twin scroll up-pipe, thats what i did together with fmic and injectors and the car is running well over 400bhp now.

Thats what id do. Does the JDM have the proper forged pistons or are they hypereutectic ? I think it may only be the UK and U.S that has the hypereutectic ones.

Somebody mention me.....Yes I have the stage 4 powerstation kit fitted to my car and yes I am happy with it, it does what it says on the tin at the end off the day it depends what you want out of your car for me its a quick a /b road car with the odd trackday thrown in if I was just doing rwyb's then I would have gone for a big single turbo.

funnyclub

Yes mate thats the kind of thing I am looking for as well.
Did you have to exchange your turbo or what way did it work?
And did you have to have other parts fitted at the same time?

JDM are hypereutectic aswell to the best of my knowledge.
