1991 Twin Turbo non Turbo Bumper Help!!!

Hi, I currently own a 91 Twin Turbo that I need some expert advise on. Back in October I got into a front end collison and had to replace the bumper and a few other things as well. I went ahead and purchased a non Turbo bumper from a Junk Yard up in Virgina and had it shipped down to South Carolina for my Body guy to sand and repaint accordenly. The bumper was installed with no problems and looks great. I havent driven the car and just got it back this week from the Body shop. I guess what im trying to get at is that with this new bumper there are no intercooler vents on either side of the bumper to let air into the intercoolers and im worried that this could lead to some over heating or turbo malfuncting problems. Im fine with the way the new bumper looks cosmetically and already have put a lot of money into the car since the accident. So do you think my Fairlady will be ok mechanically with the Non Turbo Bumper?

No. It is very bad for your motor. It could lead to detonation, which can destroy your engine, because the engine and fuel maps were designed to do 9psi on a cooler intake charge. By blocking your intercoolers, the air going into the cylinders will be EXTREMELY hot, and will only get hotter under cylinder compression. The difference between a stock intercooler and a good intercooler is about 100 degrees... the difference between a stock intercooler and no functioning intercooler at all (which is basically what you have) is about that much, as well.

At least cut openings for the intercoolers. Or you can be a respectable Z owner and buy the correct fascia.
