Digital Posted April 5, 2010 Share Posted April 5, 2010 Hey guys. I have some questions concerning mapping a Supra 2JZGTE. What boost can a stock 2JZGTE handle? What AFR and timing can I run in midrange and topend on a stock 2JZGTE-engine? What is a safe/good EGT when running boost between 1,0-2,0bar?

Guigsy Posted April 5, 2010 Share Posted April 5, 2010 on jspec turbos' 1.2 is usualy the accepted max i think. You can push the uk/euro/us turbos to 1.4 at the very most but people tend to stick to 1.3 max. No idea on your 2nd question. Regards the 3rd question you wont last long at 2 bar with stock turbo's Happy to half help Quote Link to comment Share on other sites More sharing options...
Digital Posted April 5, 2010 Author Share Posted April 5, 2010 Thanks, but I'm talking small and big single turbos with a stand-alone ECU Quote Link to comment Share on other sites More sharing options...
InSvain Posted April 5, 2010 Share Posted April 5, 2010 Digi maybe it`s helpfull if you define small and big turbos because there are alot of turobos out there Quote Link to comment Share on other sites More sharing options...
Guigsy Posted April 5, 2010 Share Posted April 5, 2010 ah. well, you did say stock gte Jamiep/leep would be the best people to ask about this. Or Paul Whiffin. Not many other people have run high boost on stock engines in this country. (dont think pauls was stock). Jamie has run 2+ bar on stock internals and got 700+ bhp, seems quite reliable as its run for a while like that. Quote Link to comment Share on other sites More sharing options...
