Just better of going to me for a real A4 1.8t turbo setup with a Full-race manifold. I am a Garrett and FP(HTA) dealer.

Here is what a near 835chp A4 1.8t looks like.




I was the very first B5 A4 owner to go 2 liter and first to go equal length tube manifold which is the Full-Race manifolds I sell.



A great street setup, FR manifold with a GT2871r that has a T3 exhaust housing.

You might have an exhaust leak or your wg arm might be loose. It could also just be that your BPV is bad. That or your turbo is just dead, if so I have a stock K03 off a B6 that has 55k miles for $200.

Will a exhaust leak do that? I have a leak right where the DP and turbo meet. Whats BPV? I feel like a noob now lol. The WG arm is fine I checked.

Exhaust leak after the turbo wouldn't cause low boost but it will cause the car to think its running leaner then it really is.


BPV = ByPass Valve.

If Full-race makes the manifold I can get it. I guess you want the single scroll? Is it or a S13 or S14?
