Ya it's a tight fit.. There is about 1 1/2 between the firewall and the back of the motor... I have the IC mounted to where about 1/4 of an inch of it stick out of the corse support then the rad is about 3/4 of an inch from the IC then the fans are about 1/2 and inch from the engine. But the interesting part is going to be the IC pipeing.. I'll be hitting that this weekend
