hi there I am looking to change my engine in my nova gsi from a 20xe to a c20let engine has any one got any advice or pics of intercooler set up as I want to retain my standard front bumper the standard plastic bar has already been cut out and mesh fitted but I don't want the intercooler sticking on the outside I want it hidden behind bumper, which intercooler is the best type to use make model size etc.... also what size exhaust do people use, is it a 3" exhaust system best to use...?? I was thinking of having a exhaust system running from turbo and to exit the side of drivers side front bumper what do people think how loud would it be and is it possible ....???
