I'm a bit 2nd gen retarded....my bud has a 1991 vert he wants to turbocharge and is looking for second opinions as to the feasibility of keeping all 6 ports open.

thanks guys--

 

you can do something like this that my tII manifold already grind to fit a 6port engine

that or buy a spacer that goes to betwen the engine and the turbo manifold

 

Aaron Cake did it, go search in the second gen forum.

 

my friend did his turbo 6 port a year before aaroncake .. here is a pic ...

 

I am not sure you compression ration would be good for boost over 10 psi.

 

Why not? Rotary Performance has built a few 3rd gens using 9.7:1 compression rotors putting out over 400 hp. I wouldn't think it would be appropriate much above that level but as long as you can tune it well there shouldn't be a problem. I would worry however if someone were still trying to use a rigged stock computer system.

 

Damn! I did'nt even post that last reply!? I don't know **** about boosting limits! How'd that happen?
