Ok prepare for all number of stupid sounding turbo questions from me as i am trying to work out how to do this properly. Yes i have read up on them but some stuff still doesnt make that much sense (due to the ppl who write articles on them knowing much more about them than i do ).

Anyways for starters now i think i am looking for a t4 garret would this b suitable??? and the housing, does that make any difference other than the mounting???? And could i mount a t3 housing onto my car without too many problems? Obvioulsy i would have to modify my exhaust manifold or make one to suit, but as my mate is a welder @ fords i dont see this being much of a problem tho . Thanks

Did you read this...

yeah i did chef many times btw nice work on it. I just have basically no knowledge of turbos and have to ask stupid questions to get it all to make sense in my head a guide that ebxr put up on turbo mustangs is helping a bit but im still a bit lost

t3 might be a bit small and restrictive at higher revs. check out pre fab kits from snort, they give a good range at a good price.
