well after having trouble finding a 4g63 non turbo motor for my 1988 mighty max I decided to with an old 4g54b a 2.6 from a 1986 mighty max, I stripped the motor sent it to the machine shop, got 20 over pistons and a silent shaft delete kit after I put the motor into my truck with a weber carb and 2" exhaust it has a lot of torque but not much HP. I ordered a new performance camshaft that goes into the evo motors which should boost horse power giving me more acceleration and top end speed
