Delboy52 Posted February 28, 2017 Share Posted February 28, 2017 Also, the engine runs out of puff after 5000revs, and although I have plenty of fun torque and usable power, I'd like to improve the intake side as I reckon thats letting the engine down. Still deciding whether or not to explore this, but I have a few ideas...... I have a larger custom made intake on my 1UZ VVTi, but the bottleneck for that is still the pokey little MAF sensor conduit. If you go Syvecs you can also ditch the MAF bottleneck restriction and have MAP via an unrestricted intake. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 28, 2017 Share Posted February 28, 2017 Had 30 out of mine once but that was driving very sensibly on a long run with no stopping other than for fuel in mainland europe Womder what the 6 speed UK can do with it's lower geared diff?

Shane Posted February 28, 2017 Share Posted February 28, 2017 I have a larger custom made intake on my 1UZ VVTi, but the bottleneck for that is still the pokey little MAF sensor conduit. If you go Syvecs you can also ditch the MAF bottleneck restriction and have MAP via an unrestricted intake. You don't need to go Syvecs to do that, ECU master DET3 or even the most basic of the MAPECU range piggy back would make that possible for a lot less money. Its a very common mod used by the BMW modders for MAF based engines. Take a look at the ECU master website at the DET3, there's a great forum too where you may even find someone has already done this for a 1UZ. Its something I intend to do if I ever get any further with my 1UZ. Sorry for the hijack Ed. Quote Link to comment Share on other sites More sharing options...
Delboy52 Posted March 1, 2017 Share Posted March 1, 2017 Ed was considering fitting a Syvecs anyway so he'd get MAP with that as a consequence. Great that you posted an alternative though Shane Quote Link to comment Share on other sites More sharing options...
EdMorris Posted March 1, 2017 Author Share Posted March 1, 2017 All good posts there, thanks for input. I knew I was getting poor economy, but then it is almost 5L. Does anyone know of a good metal fabricator? Quote Link to comment Share on other sites More sharing options...
