My question is if i bolted up a Neukin or Full Drag Turbo Manifold along with the t/3 t/4 turbo and tial wastegate would this interfere with my A/C unit? it looks that way but i wasn't sure also whats better garret t3/t4 turbo or garret t25(used in edelbrock turbo kit) my goals are about 400 whp eventually, i heard t25 spools faster but not sure. thanks in advance!

 

Man it looks like you need to do some searching. But yes, full-race and neukin offer a/c compatible manifolds.

 

your not gonna make 400whp with a t25. too small.
