you need to know what your budget is. id say at least 3500 is a good start. yes 3500.Has anyone turbo'd a 3.5 or 3.7 if anyone has where do I need to start
I second that^ even being a daily driven 3.7 Turbo guy. the 3.7 with a turbo is fun no doubt, but its got its limits without spending a ton of money on forged parts/engine work/etc. I know Emaxxer would spit on my grave for saying this but IF i were to rewind to before I put the turbo on my I5 I would just go ahead and swap in a medium built 6.0l ls motor and 6 speed manual tranny and probably be about the same place I am with the 3 different manifolds Ive made and tinkering/redesigning Ive done in the past 2yrs... I love my I5 tho too cuz its super uniqueyou need to know what your budget is. id say at least 3500 is a good start. yes 3500.
there are a few who have done it, but you need to be honest in what you are looking for.
high hp? in my eyes, in the long run a v8 swap will do what a turbo i5 will do for half the money, more reliable, more tq, and last longer.
