I assume that you have used this method before? How did/does it hold up? Link to comment Share on other sites More sharing options...

Just thought you would wanna check since how your going to all the extra effort to make sure everything is balanced together. 1 Link to comment Share on other sites More sharing options...

turbotrana Member 2,586 Member For: 21y 9m 8d Gender: Male Posted 20/04/15 01:25 AM Share Posted 20/04/15 01:25 AM (edited) I hope those fire rings work out. Where did you get them. In my day could never find them. They look a bit close to the water jacket though.You didn't touch the flats on the chambers. I know with the Supra mob they used to take out one side (I think the exh side) as it was a souce of something (think detonation). I am talking about very high boost mtrs. But with ethanol not really a problem maybe.How much attention to the oiling system have you given. I've done mtrs where there has been minimal attention to detail to oil passages to alot of teardroping of every entry and exit hole and the big ends definately were heaps better on the prepped mtr after abuse. A 3mm metal burr grinding bit is your friend here. Some of the oiling holes are not even centered very well so it all needs attention in performance applications IMO.

But from memory when I measured the I.D's of all the fittings the ethanol sensor was about 8.8mm with the -8 Teflon hose being around 9.1mm.. The smallest part of my system is the fittings that screw into the KPM module, being 1/4 NPT was about 7.8mm I.d so I think the way I have set it up will be the most efficient for this system Link to comment Share on other sites More sharing options...
