Chris Wilson Posted May 18, 2016 Share Posted May 18, 2016 If you want the ceramic J-Spec cartridges you will have to buy new complete turbos from Toyota. The part number has superceded to the VVTi ones, which interchange. I am told they will shortly be off the parts list as when stock is exhausted that's that. Lasst ones I bought were about £1500 plus VAT each, from a UK Toyota dealer. Quote Link to comment Share on other sites More sharing options...

I definitely do NOT want ceramic stock cartridges, I see many replacement options out there but I'm trying to sift through what's junk and what's actually a good product , Quote Link to comment Share on other sites More sharing options...
lintlars Posted May 18, 2016 Author Share Posted May 18, 2016 Ok me again so they have different part #s but are the turbine and compressor wheels the same size on each turbo? This site leads me to believe they are just different housing outlet sizes as per the quote below. "The turbochargers themselves are identical in size with the exception being the rear turbochargers exhaust housing which is 23.7mm longer and does not contain a wastegate, instead it contains an exhaust bypass valve which is used in the sequential operation to transition this turbocharger online with the primary (#1) turbocharger so both turbochargers are producing equal amounts of pressure and flow." http://www.turbosupras.com/pages/en/pages/technical/CT20%25turbochargers.htm Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 18, 2016 Share Posted May 18, 2016 The Jap spec turbos are the most reliable and flow the most air, they would, by far, be my OE turbo of choice. This was done to death years and years ago. Quote Link to comment Share on other sites More sharing options...

This was done to death years and years ago. yes I agree with that I'm looking for a vendor that sells new cartridges not used turbos, I have three sets of jdm twins and all issues I see all over the internet vendors selling them but was hoping someone has already went down this path and I believe both turbos are identical with the exception of the housings , I will disassemble the ones I have to confirm I was just wondering if its already been confirmed or not Thanks everyone Quote Link to comment Share on other sites More sharing options...
