previous owner put in the n/a 5/8" core instead of the 1" core that comes with the supercharged engines. my car heats up under stop n go or medium to high loads.
new drilled 180 thermostat and pcm is programmed to turn fans on at 185* ive seen temps a tad bit over 210 already.
while i am going to replace to a stock 1" unit, thought maybe i could get a bit more cooling capacity with the dual core out of the 04+ cars. if it will fit without hacking anything up.
