I am in a bit of a dilema at the moment. I think alot of my pinking on my engine is due to the bad flowign manifold. Which option do you think would be best.
1. Std C20LET turbo proven by most to be capable of running 20psi. quite compact.
2. Stainless steel manifold similar to the one in this picture probably for a T3.
3. Courtenay cast manifold for T28.
