GrandPrix34 Posted August 12, 2003 Report Posted August 12, 2003 i am gonna buy a stock front and rear manifold for the DOHC. Someone, i believe it was Vegeta who had the perfect sizing for the pipes. I spoke to a local muffler gyu and he said to take him some stockers and the sizing and he will mandrel bent them in place. He even hash the engine puller thingy to custom fit them? wat would i need? Quote
RomeoZ34 Posted August 12, 2003 Report Posted August 12, 2003 Do you have an auto? If so, good luck, and make me a pair while your at it. I'll pay ya =) I know John (Veruth I think), aka KickingZ made some for his 5-speed. Might try to get ahold of him. Quote
slick Posted August 14, 2003 Report Posted August 14, 2003 The thing about making headers is the fact that all the header pipes off the engine have to be the same length (i forget the exact reasoning). The diameter of the pipe has to be a certain size to be able to push out the air, yet not letting soo much air out that its losing power. Also the fact that this is a FWD V6 car, this will be fun making these just right. But hey, if it works, PM me, and im buying a set. Quote
GrandPrix34 Posted August 14, 2003 Author Report Posted August 14, 2003 http://fiero.cc/fiero-tdc/members/mws/headers/ i still need to buy the ehaust manifolds.... i was wondering if i put 97 stock headers on my 93, if there would be any gains at all seeing as how the 94+ gained horsepower. How bout intake wise, if i put a 95 lower intake would that help at all? Quote
Vegeta Posted August 15, 2003 Report Posted August 15, 2003 1 5/8 diameter unless you plan on over 285 hp, then its 1 3/4. Length is something I have forgotten but I know it was quite long. Probably going to have to use whatever he can fit on an auto car. stock 97 wont match a stock 94 head, because the port shape changed a lot. Quote
