FE head for perfomance

Recommended Posts

The plan is to run 3SGTE rods. The 5SFE run 52mm rod bearings and the 3SGTE run 48mm. It gives you a bit of play with stoke at the right machine shop and should hopefully mean I won't need any custom pistons or rods. I only need to machine off as much of the piston to bump the compression from 9.5 - 10.5 : 1, possibly 1 - 2 mm, the rest can be done with a thin head gasket. They're a dished piston and machining a little off the edges won't actually touch the integrity of the piston in the center, I think they're thick enough to handle it, and this motor will be built on a budget. I'll counter the shorter pistons with an offset reground crank. It'll be interference, but that's gonna happen with the cams I want to run anyhow.
