i am building a twin turbo setup for my 5.0 mustang ..just had a few questions about GN tubos before i buy some. hope you guys dont mind me on the buick site.. does any body see any advantage to using either "hot air" or intercooled versions for a homemade setup? what is the difference between the two? A/R size etc.? 84-86 was hot air and 87 was intercooled..is that correct?Thanks for any input Mike
