Not to let the cat out of the bag, but i been talking to to someone about making an affordable intercooler/ Twin screw blower swap. That will come with one of the most effecent inter-coolers like whats found in a ls9 corvette Not a heater core out of a ford that leaks after a few miles are on it. This is the best out there. Top it off with a blower that's just hands down better. We all know twin screw design build boost quicker and with less heat. We all know the eaton 90 can easy get up to 320 degs inlet air temps non inter-cooled.
This will be affordable.
