danielk Posted April 24, 2014 Share Posted April 24, 2014 One or more of the rod bearings are gone on my current Supra TT with 2JZ-GTE. I want to import a low millage 2JZ-GTE from the United States from Ebay. The Aristo 2JZ-GTE's with VVTI are cheaper than the Supra 2JZ-GTE's and easier to find. I want to build a single turbo on the new engine but if I buy the VVTI I want to get rid of it. This because I have a Apexi Power FC which doesn't support VVTI. Besides that it seems to be hard to find a tuner who can map VVTI and I maybe want to mount aftermarket cams. So what’s involved to convert a Aristo 2JZ-GTE VVTI to a non VVTI? I can use my old engine for spare parts. I searched the forum but couldn’t really find an answer. Do the Intake cams from a non VVTI fit in the a VVTI engine?

David P Posted April 24, 2014 Share Posted April 24, 2014 Using the VVTI bottom end with the head and sump from your existing, it would be doable. Quote Link to comment Share on other sites More sharing options...
danielk Posted April 24, 2014 Author Share Posted April 24, 2014 (edited) Thx, but i don't prefer to take the head of if there is another solution . Then i need a new head gasket and valve stem seals because mine are worn. And probably the new head is in a overall better condition.

Chris Wilson Posted April 25, 2014 Share Posted April 25, 2014 Youm could lock the VVTi system up solid, but you would still have the issue of not many performance profiles being available on the VVTi cam casting, should you want different cams. Personally I'd spend the extra for a none VVTi engine. Plus i think the Aristo upper and lower sumps are different and would need swapping.

Swampy442 Posted April 25, 2014 Share Posted April 25, 2014 Why don't you just rebuild your own engine? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 25, 2014 Share Posted April 25, 2014 A good used engines will be miles cheaper unless you can do it all yourself, even then an engine that's suffered a major rod bearing failure will be needing a crank and oil pump, and new rods. If you strike lucky with a GOOD used engine you should be spending a lot less. Quote Link to comment Share on other sites More sharing options...
danielk Posted April 25, 2014 Author Share Posted April 25, 2014 What Chris said. A complete rebuild is too expensive. When i buy a good used engine i can sell the spare parts i don't use. That would be the cheapest solution. I didn't know the 2jz-gte vvti head casting is different compared to the non-vvti head. Quote Link to comment Share on other sites More sharing options...
