Welcome to the "Club" your going to fall even deeper in love with it.
Did you say you were having a heat exchanger MADE??? What does your neighbor do for a living that he could do this safely? For the price of the L.E.T.'s H/E you can't go wrong and ask anyone on this forum I am not into dropping name brands and I am deffinatly into fabricating yourself and exploring outside the box. Just hope what ever you do you have good luck with the car. I have an Aero Blue, lowered 1 3/4" with a 185mm crank pulley self fabbed dual CAI, L.E.T. Heat Exchanger and ECU tuning by Jerry and she runs incredably strong. PLUS!
NO TOP END LIMITER other than friction, gravity and God!!!!
Enjoy the Ride...
