Well thinking since I have to buy all new internals and I already built a t70 kit to try it out on a 383. I think the turbo is gonna be on the small side. What does everyone think?

 

I think your right. I would go with a t76.

 

+1 on the T76. Would be a much better fit.

Ya my buddies made 600 on a 5.3 with the smaller ar exhaust housing. If it would support 700 i would be fine. The more I look at it I will pry just do the 355 setup and wait for mahles pistons to get made.

 

pretty big difference between a 327ish and a 383 though.

I think the exhaust would be choked. It would make great torque and run out of steam up top.

I would do a 76 for anything bigger than a 35x - honestly many people say its too small for a 350 but we are starting to show good results.

 

Ya Im gonna build a 355 so I can see what this little turbo is capable of.

 

do you have all the specs on that t70? Because some 70mm turbo's are bigger than others, things like trim, housing size, etc, etc all come into play. But most likely its going to be on the small side.

 

mp t70 is not a 70mm, its 68mm.
