i have a streetport 3mm seal engine in my 93 rx7. buying new turbo, curent turbo is a t3/t4 with a T-4 exhaust flange and housing but new turbo that i am looking at is a t3/t4 with a T-3 exhaust housing. What i want to know is what will the difference be in the turbo and performance if i went with the turbo with the T-3 flange instead of the T-4?? Any information will be helpful, even personal prefrences!!! THANKS allot!!! LONG LIVE THE ROTARIES!!!!

 

i love how everyone calls it a t3/t4. that means absoltely nothing except it is half and half.

word of advice. if you want your rotary to "live long" dont put a t3 on it.
