supraguye Posted January 10, 2008 Share Posted January 10, 2008 Guys, Quick question: Are the stock turbos on the J-Spec vvti different from those on the J-Spec non-vvtis ? Thanks Dudley Link to comment Share on other sites More sharing options...
Alex Posted January 10, 2008 Share Posted January 10, 2008 I belive the turbos are the same BUT the Exhaust gas bypass (between them and cat 1) is different. Link to comment Share on other sites More sharing options...
supraguye Posted January 10, 2008 Author Share Posted January 10, 2008 Thanks Alex. The thing is, in the technical area I posted this thread: http://www.mkivsupra.net/vbb/showthread.php?t=136536 Chris Wilson suggested one of my turbos may be bad and hence what I am looking to do is replace it with a ct20a from a non-vvti. This really is just a temporaty measure until I save up to go Single later this yr or next yr Link to comment Share on other sites More sharing options...
Nic Posted January 10, 2008 Share Posted January 10, 2008 Not sure what the differences are, but the VVTi turbos are a straight swap onto a non-VVTi Supra. Link to comment Share on other sites More sharing options...
supraguye Posted January 10, 2008 Author Share Posted January 10, 2008 I would think they are the same because I have been reading loads of MKIV articles and haven't seen anything regarding a turbo difference Link to comment Share on other sites More sharing options...
Nic Posted January 10, 2008 Share Posted January 10, 2008 I would think they are the same because I have been reading loads of MKIV articles and haven't seen anything regarding a turbo difference The VVTi turbos have a different part number so there must be a difference, they do fit the same though.

heckler Posted January 10, 2008 Share Posted January 10, 2008 CT20 is fitted to 4-runner, camery, Hi-ace, hi-lux, and landcruisers.... Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 10, 2008 Share Posted January 10, 2008 OK, I was of the impression the VVTi turbos were different in the exhaust side bolt pattern to none VVTi ones, and wouldn't swap unless you used the whole caboodle? I haven't tried this though, so are we sure they just swap over? For sure they are a different part number, and more expensive than the pre VVTi J-Spec turbos.

The non-VVTi turbos are no longer available, the EPC image shows the VVTi turbos as a substitute (abbreviation SUBS on the left hand side) for the earlier Supra turbos. http://img410.imageshack.us/img410/9426/picture1ep2.png Link to comment Share on other sites More sharing options...
