Luxluc Posted May 22, 2015 Share Posted May 22, 2015 I found this thread on SF super interesting. http://www.supraforums.com/forum/showthread.php?918697-GTE-non-VVTi-to-VVTi-conversion-Facts-and-myths I have been playing with the idea to replace my non-VVTi head with a VVTi for some time now. Seing how superfast they spool compared to non-VVTi, it is certainly a big PLUS for a street Supra. I think that may become my next winter project. I wanted to share this info with you guys ; so far Jamie runs the only nice power Supra running VVTi, but I think it's the route to go. Link to comment Share on other sites More sharing options...

JamieP Posted May 26, 2015 Share Posted May 26, 2015 I've driven/owned pretty much everything supra wise. IMHO VVTI is great, 2jz in stock form feels a pretty lazy old lump, but the VVTI brings it alive, it feels like a high comp engine when compared to non vvti. And on single turbo cars it gains you great spool time and just makes the car feel more lively. All round win imho Link to comment Share on other sites More sharing options...
Alex Posted May 26, 2015 Share Posted May 26, 2015 There's an HKS 3.4 VVTI out there which TDI did...that was pretty good too... Link to comment Share on other sites More sharing options...
JamieP Posted May 26, 2015 Share Posted May 26, 2015 That one blew an engine and got broke for parts Alex. Link to comment Share on other sites More sharing options...
johnny g Posted May 26, 2015 Share Posted May 26, 2015 My VVTi spooled pretty well, even with the big old 3071HTA's on it. Made a great street car. Add DBW, too. Link to comment Share on other sites More sharing options...

VVTi on a 2JZ with a midsize turbo seems to be the perfect street combo Link to comment Share on other sites More sharing options...
costas1 Posted May 26, 2015 Share Posted May 26, 2015 Great info..can someone pls explain what drive by wire means?instead of an idle valve? Link to comment Share on other sites More sharing options...
Wez Posted May 26, 2015 Share Posted May 26, 2015 DBW is electronically controlled throttle, not a traditional cable. Link to comment Share on other sites More sharing options...
JamieP Posted May 26, 2015 Share Posted May 26, 2015 I removed the DBW On my car, I hated it. People say it's better with a vette TB though. Link to comment Share on other sites More sharing options...
johnny g Posted May 26, 2015 Share Posted May 26, 2015 I removed the DBW On my car, I hated it. People say it's better with a vette TB though. The stock DBW is pure arse. It's cable assisted DBW, so there's a mechanical delay. The Corvette TB is much, much better. It'll allow better pedal vs throttle mapping to your taste/liking and allow Syvecs to add an extra feature to the traction/launch strategies.

Luxluc Posted May 27, 2015 Author Share Posted May 27, 2015 Good info on the DBW. So Lee removed yours Jamie? Link to comment Share on other sites More sharing options...
JamieP Posted May 27, 2015 Share Posted May 27, 2015 Yeah, stock one is rubbish. When I fitted the SP intake I just went with a normal 90mm Ross racing TB Link to comment Share on other sites More sharing options...
