Good thread here!
I just scored a GE motor that I'm going to make turbo. Mainly the block and head will be GE but harness, ecu, coils, ignitor, etc will be 7mgte Internals will be 7mgte also like the PISTONS! no high compression.
Is there a way to open that hole up bigger and tap it? That is exactly where I was hoping to use for my return.
