I know some of the older z's had a t3 which I think is .60/ .63 but what size was the other turbo offered? Was it a t25 or a t28? I thought I had a t25 with .42/.48 but a guy on ebay who claims to have been rebuilding turbos for 14 years is selling the same turbo I have claiming it's a t28. Is he correct? Here's a link:http://cgi.ebay.com/ebaymotors/Rebui...04677396QQrdZ1

 

older Zs(late 80s I think) came with the bigger t3s and the newer twin turbo ones came with t25s

 

The 88's on for Z31's had T25's, not T3 .60/.63s according to www.z31.com

 

Yup, I got an '82 T3 from a 300zx, Stamped right on the housings .60/.63.

Got aother replcement coming in this week with the same thing.

Newer gens are t25. This is when the went to a twin turbo setup. The older ones where larger single turbo setups.

 

No guys they offered two different turbos in the older single turbo z's. The last couple of years they switched to a different turbo. I think the twins on the tt z's are t-25's but I'm trying to figure out if the last couple of years before the tt's were released were t25's or t28's. The t3's were the first turbos offered on the single turbo z's from what I understand.

 

T3 = early z31 chassis, up till 88
t25 = late z31 chassis, from 88-89
t22 = z32 chassis
