I think I am going to skip the 7M transplant and stick with the turbo 5M. Someone told me once that I should go with the 7M because you will hit a HP wall quickly with the 5/6M's unless I plan on going crazy with it. Well, I want to. Here are some questions...

Does the 7M crank raise compression? What is it's advantage over the stock crank?

8.3:1 is the ideal comp ratio for turbo, yes?

I know that custom forged engine internals can be made for just about anything...does anyone here have any custom rods, pistons, etc? I bet those puppies were expensive....

That's all for now. I'm sure you guys love having someone's questions to answer(I know I would:))

Thanks in advance

Yes, the 7m crank will increase the cubic inch displacement and that will increase the compression ratio so I've been told. You could go with a fatter headgaskit to try to lower the compression. The 5M crank should be plenty since CID isn't that much of an issue when you have boost. :smoker:

Yes.

Clueless here, perhaps about $100 per piston and about $1000 for a crank...

That's all for now. I'm sure you guys love having someone's questions to answer(I know I would:))

Thanks in advance

will you use the turbo block? Highly reccomennded. Wade is correct about $100ea for forged pistons, I have a stroker kit to raise compression 11:1, as I am running a NA

Axeman, what do you mean by the 'turbo block?'
