Big t-28? Worth the money?

[pdx96gsx]

I am debating upgrading my turbo to a forced performance big t-28.
My car is under warranty and I am told you cannot tell the turbos difference from the outside.This is good for me.
What I would like to know is what kind of power can I expect?
My car is pretty much stage 1, minus the fuel pump and downpipe.
Will I need bigger injectors along with an s-afc or will the stock injectors handle? (providing I do my fuel pump(190lph)
Thanks to all!!

u dont need injectors, afc, and a fuel pump....just as long as u keep the boost down u should be fine.
BUT if u want to see the turbo's full potential (+-300hp) then yea u need all three

I ran my AGP t-28 on 15 psi fine with just a 190lph pump. It made 224hp to the wheels just bolted on. But like someone already said, you'll have no idea what the turbo is capable of until you get the injectors and SAFC. Also be prepared to do some porting, mainly on the o2 housing and exhaust manifold while you have it off the car. It's alot easier to do it that way than to have to take off the turbo 3 time because of creep.

Thanks! Can you recommend a size injector or company?
I have heard Denso's are good, also RC.
What kind of boost can I expect to run on pump gas(92)?
(Considering port work and the s-afc/injector done)

 

[crashed97tsi]

I went with RC 550cc injectors. Can't complain about them, but supposedly denso's are a little better. I don't know what psi you cou;d run on 92, put I would assume at least 15, probably more.

Yes, Deffinately worth the money. I'm running 17psi with a 190lph pump and otherwise stock fuel system. If you have any questions feel free to pm me.

I run 15psi on the stock fuel system with mine. I wont run more than that. I EGT peaks at around 850C in 3rd and 4th gear. and Its fun beating people with a "stock turbo"
