View Full Version : Down pipe questions?

12-12-2010, 10:51 PM
Hey so i own a 1991 gt4 just got a garrett t3 t04e 60ar turbo and i need to know what type of downpipe to get for it cause ill i can find are five bolts and know fours. It needs a four bolt and was just curious if u can just hook up to a five bolt and just not put the other in. Any advice please help me out thanks.

when you say "4 bolt" and "5 bolt" are you referring to the stock configuration exhaust housings like from the first and second ct26 respectively? If so then the answer is no. A 5bolt pipe will NOT bolt to a 4 bolt housing. However, Im confused, if you have an aftermarket garret t04e then Im surprised it would have a CT26 style exhaust housing so maybe you are referring to something else?

pics would help.

i think i do ebay! i think what you are looking for is the hot side so look for a t3 decat pipe and it should come up!! or are you talking about the setup of the gt4 turbo?

If you are not using the stock turbo, you can't use a downpipe meant as a stock replacement. Where did you get the turbo? I would be amazed if they didn't offer a downpipe to go with it, you must have gotten a manifold that works with it.

Your writing confuses me a bit.

Answer this question: is this a CT26 based turbo? (Yes/No)

After that I can answer more.
