how much horse power can a stock head gasket hold? whats a good chip for the b5 models? and would i need new injectors for the t3or t4 turbo?

 

More than your car will ever make... Giac or APR are popular... And yes.

 

I still run a stock ATW head gasket at over 800hp. lol

Yes you will need larger injectors, no way possible the stock 210cc/270cc injectors are going to give you enough fuel for a T3/T4. Even with a K04 tuners go with slightly larger injectors and most use 415-630cc injectors just for the little Elim kits.

 

wow head gasket pretty strong. looks like im gonna need injectors thanks guys
