This may seem like a really stupid question but if i go with a T3/T67 turbo on my car do i have to find a specific manifold or can i use a T3 or a T3/T4 manifold?

 

t3/t4 manifold should work fine

 

A T3/T67 IS a T3/T4 turbo. A T3 exhaust side and a T4 compressor side. There is no specific "T3/T4" like you can say "T76" or whatnot. Even though there are some different variations of T76's in terms of exhaust housings and wheels, that's the best example I could think of

 

depends how much clearance you have with your previous manifold. i know wit my old manifold i wasn't able to fit a t3/t4S so i had to change mani's
