I bought low mileage 7 bolt 4g64 DOHC Galant engine for a project that I have now abandoned. I know someone who has a 1996 GST with a bad engine.
I think the head on these engines are identical with the exception of the cams, cam gears, and cam sensor. If that is not the case please correct me.
We are considering putting the Galant engine into the GST using the turbo setup. I know the compression ratio is way to high. I'm wondering if we could just get a set of lower compression pistons and be good to go? Are the connecting rods in the 4g64 strong enough or will we have to worry about them not being able to hold up? I can't be sure but, I recall somewhere someone saying the rods were the same. It may have been a 6 bolt 4g64 they were talking about.
If this will work do I just need to hone the cylinders to get the new rings to seal?
A JDM 4g63 engine will cost around $1,200. Going the 4g64 route appears to be cheaper if it will work.
