I have ran a couple ideas across some members here and i appreciate your replies.
I want to do the 2.7 conversion but with the 2.5 longer rod. From what i have researched the 2.5 rod on a 2.7 crank spins faster than the 2.7 crank/rod.
I know the other possible alternatives - 2.7 (eta)crank/rod/piston/ i head. or - 2.7 (eta)crank/rod, seta/custom pistons. I have read all there is to read on these two (twice). I can't find the seta pistons and customs with this setup are difficult to get pricing for. Had difficulties trying to get correct specs to order pistons.
Regardless, I like the more tourqe to come from the 2.7 crank and the faster rotation from the 2.5 rods. A few have brought this configuration up, but i have not noticed much detail on the subject from those that have actually gotten this done.
1) I have only seen the reference to .080 shave off and relief recut once.
a) Is there a certain amount of shave verses CR amount?
b) will any machine shop know how to do this?
2) Details/specs of custom pistons with CR.
Anymore information would be appreciated.
Oh, this will stay a NA motor.
Thanks, rvaughnp
