The 3rd gen 3s powered celica and mr2 had it. The CT-20B isn't the real name of the turbo, its kinda a slang term the mr2 community uses to separate the 2nd gen 3sgte turbo from the 3rd gen turbo. The turbo comes on 3rd gen 3sgte engines and has a ceramic wheel and better intake and exhaust housings than the 2nd gen ct-26. it also has one more bolt(7 I think) in the exhaust housing where it bolts to the downpipe and just says toyota on the intake, instead of toyota ct-26. The real ct-20b is actually a turbo off some 80's truck and does not bolt to the mr2, but everyone refers to the 3rd gen ct-26 as the ct-20b so oh well. Just be careful when your shopping for one. The car looks great, I'm more of a fan of the stock bodied mr2's but you found a good deal. make sure to get on mr2board.com and mr2.com, I have the same name on both so look me up if you need something, I have a couple spare parts laying around. Also look up the Berk technology exhaust, its very similar to the one you posted and I have and love it, great price on them too.
