I picked up a '93 FWD Impreza a few months ago and I am doing a budget high compression build. EJ18 heads on EJ22 block.
My big question is where is the main choke point in the EJ18 heads? Because I can have some over sized valves put in for cheap. Or is port work more of a necessity?
Would EJ25 SOHC valves work well on this setup?
What head gaskets should I use? EJ18 or EJ22?
How high can I rev this thing before oil starvation to the bearings?
