Question about pfp manifolds

[Little_Franny]

So I bought a pfp a little while ago because it was a deal, figured i would use it eventually. I was out in the garage just kinda going through parts and seeing what I had laying around when I realized that the pfp manifold I have has 8mm bolt holes and 62T cyls have 10mm holes. I read a bunch of threads about using helicoils, timeserts, drilling the manifold but didn't find anything that was specific to the PFP.

Did pfp only make one manifold? Are the guys running the pfp on 62T cyls drilling the manifold or using inserts to get the bolt down to 8mm?

I know the 61X cyls on the 62T case is a good combo, just wondering what people are doing.

Also what size bolts are the TPE engines running?

thanx for any input, I have a pile of parts and skis that I want to build something out of and would hate to drill the manifold if everone is just running 8mm bolts. I always like to know all my options before modifying an expensive aftermarket part.

All the TPEs run the standard M8x1.25 exhaust bolts. Not sure how many guys are using a PFP on stick cylinders.........I'd much rather use inserts than drill than nice manifold.

Use 8 mm

Fair enough, that was kinda what I thought, but always like to get info from people who have done before. Don't have a plan yet for the PFP, but its one of those things if I have it I might run it just for poops and giggles.

Plan is for a TPE 965 in the future, just not there yet.

Thanx for the replies

If you're going to use the PFP manifold on a TPE cylinder, you can port match the manifold to an OEM 62T/64X exhaust gasket and it will match up perfectly to the cylinder.
