can't I use an intercooler off a another vehicle instead of spending $1300 on one I have heard you can get one off an diesel or a semi and cut it down any ideas I have a 1987 nissan 300zx turbo
Of course you can get an intercooler from another car, like a subaru. You will have to make custom brackets and piping for it, but you would have to do the same for an aftermarket intercooler anyway. For all your 84-89 300zx questions, go to z31.com
Get an NPR intercooler of an Isuzu truck. Much more efficient than a starion ic. They go for about $250. If you are on a budget you can get one off a mkIII supra for less than $100.
the eclipse intercooler is waaay too small. i got an intercooler from a volvo 740 turbo for $20. it's as big as the radiator. plastic end tanks though, can handle up to about 15psi.
