Ok guys well I was talking with a buddy of mine that has a turbonetics T4 turbo off of his supra that he is wanting to sell and I had this odd ball hair brained idea of running it sequential with a stock fast spooling VGT. Ok I'm sure some of you are thinking ok so what's so different here, heck Industrial Inj and many others make kits that do this. Well the second part off this is instead of running the piping directly from your 1st stage turbo to your 2nd I thought why not add an additional air to air intercooler in front of your stock system and plumbing the hot side of your 1st stage turbo into the new intercooler then back to the inlet/cold side of your 2nd stage. I know there will be an increase in pressure drop with the additional intercooler but will the drop in IAT's counteract the pressure drop and be worth while. And has anyone ever tried this and what complications did you run into or what complications can y'all foresee by attempting this. Also has anyone tried running a much cheaper gas turbo instead of the designated diesel turbos out there. If so same thing what were the flaws if any or what would be some of the flaws.
