i bought a used t78 from a guy that had it on a supra. i have heard that there are two turbine housings offered, one for the rx7 and one for the supra. i assume the rx7's is a higher A/R than the supra's.
i was wondering if this is true, and if so what are the respective A/R's?
thanks

If you could, post a picture of the turbine housing then someone could tell you what it is. Mitsu turbos are measured in cm not a/r. I think the three available housings are 14cm, 17cm and 24cm. I was told that I have the 17cm housing on my turbo but after looking at voskos I think mine is the 14cm, his is larger than mine.
