I saw in one of the previous posts that David_K had a T3/T4OB turbo kit. Do you think you can advice me on what the kit consists of and what mods you did to the engine? I already have a clutch that can hold up to 450HP and a Dahlback chip which I can get upgraded if I get a bigger turbo.

Also what about the turbo lag, how many HP and torque 0-60 and 1/4 mile. Engine life with this turbo. Transmission?

I have an early 1999 Audi A4 1.8 Turbo Quattro Manual.

Thank you.

david K does not post here any more but he had all his internals done to to run a turbo of this size it was a complete custom kit
