I have never seen or heard that before.

And the headers won't fit and no point in trying.  Grand Prix exhaust goes over the bellhousing of the transmission.

Nevermind i found it and its for the old 3.0s. http://www.geocities.com/derekbeland/?20074

for real if you gonna modify anything just do some turbo manifolds for the 6g72 and go from there

well if there is a will theres a way removal of your winow wiper thing battery to trunk put the turbo above the tranny and y the exaust manifold to it also to hold it then run your dp off the exhaust on the turbo around the backside of the tranny and down to meet up with the rest of the exhaust I do pipe work for a living hvac acutally and i do some crazy stuff with pipe i put a lot of thought into it. I got a stock 14b here off my talon and i figured the best way to make it work with the 2.5 but i really want a 4g63 in it so when i get a garage its on lol
