I just finished swapping a jdm h22 into my 93 prelude and am having issues with air flow and overheating. When the car is in neutral it revs normal, but once in gear there is hesitation in every gear, and it feels like no power is getting to the wheels. I am thinking that it has to be an air flow problem. I put a brand new ecu and AIB box and checked all the vacuum lines but I still cant figure out why it runs so poor. Also it overheats after changing the thermostat, the fans kick in, but they dont stay on long enough or something. Should I run a straight wire to keep my fans on all the time??????? Any help would be much appreciated.
