hey i have a 97 ex civic and just picked up a t25 off of a saab from a junkyard my question is how do most ppl make them fix because i know most of the turbo manifolds have t3 flanges do you guys go with a adapter plate from a machine shop or wat ive just heard there expensive to be made or i accually found a t2 to t3 adapter flange on ebay but dont know if it would work cuz its from ssautocrome thanks???

 

i have a t25 manifold for the d16 if you want, never used. selling for 200obo

thats cool if you still have it later ill hit you but does is have a slot for a wastegate on it

 

IM pretty sur t25's have T3 flanges.
and if you got one off a saab, isnt it internally wastgated?

 

nah its the same rectangle shape but its about a quater to half inch smaller the flange that is and my turbo does have the wastegate but idk wat psi its set at and i might want to change it

 

it doesnt have a spot for a wastegate, only works with internal wastegated turbos.

T25's will either use a T2 flange, or a gay proprietary flange from the auto mfg.

The way most people get t25's to work is by using an HF manifold + adatper plate, a log/ramhorn manifold with t25 flange, or the hks/greddy manifolds (they use the t25 flange). There simply isn't enough room in a civic's engine bay to use a t3-t25 adapter plate. The only way it would work is with t25 and t3 flanges welded together, studs put in each side, and a manifold that had through-holes in the manifold that you can use nuts with. Usually that means ssautcrome, ramhorn, minime/elf, or a log with the flange extended out a bit. Either unreliable, expensive, or just not easy to find.
