I have an Ae82 sedan rolla and I want to do an engine conversion, but I am unsure what engine would best perform im looking at gettin a 4agze or a 20valve blacktop, i know this topic has been discussed many time but thiers so much discussion heaps of ppl reckon the 20 valve is betta and heaps reckon the gze is. and also which model of car should i get the engine from eg: ae92 ae101 ae111. also ppl reckon the gze would haul ova the 20valve but what if a 20valve was supercharged.
