oh and yes the oil supply on the top of the front side housing would not be used instead a oil pedestal like the one fc3s.org sell would be used to supply oil to the turbo

easy



ready? cold night+non working air sensor+shifted early in 4rth gear which created much load in the engine=boost spike=Ping=cracked plate/apex seal due to use of Pump Gas instead of Race gas



and yes my A/F's should of been in the low 11's for pump gas

but was running 11.8 A/F-11.9 A/F which seemed very nice on race gas and made alot of power but was border line on pump gas

That front plate oil bypass mod has been done by racers if the rules allows them to do it. One problem is this totally bypasses the front OPR, and you get raw pressure coming off the oil pump. The good thing is that you don't have to deal with the stupid o-ring in the front cover!

Ok, Now I am lost, First they said:








How much boost are you running? What A:F are you running? How much HP are you running? What timing are you running? Every time I ask a good tuner about S4 plates and cracks they tell me to tune it properly and there will be no need till you get well over 500hp. Were you running the Microtech when this cracked?

It wasn't my car, but the engine was a 4 port bridgeport running a carb and distributor, on dual stage nitrous. Retard was controlled by MSD units.





and now they say:

Ted, I uh https://www.nopistons.com/forums/pub...1047683561.gif



I was talking about flowing the oil back into the engine at the front plate instead of the rear one. I understand that it would sort-of bypass the rear pressure reg, but the oil passages are interconnected, so it shouldn't really even be a problem.



Well, either way, I still have the option of using the rear plate since I've found a way that ought to work quite well. Should I just forget about the front plate?

Oh, I was just replying in general.



Reading all of that other stuff made my head hurt. :(
