moobaque Posted February 19, 2008 Share Posted February 19, 2008 Sorry, but you have missed the point of having a baffled sump - The point of the baffles isn't to keep your oil cooler, but rather to prevent oil starvation under hard cornering/load, which is particularly common at the track.Ideally, anyone building an engine should be at a minimum fitting sump baffles, a good quality oil cooler, and an upper oil gallery restrictor. If hes doing that kind of cornering and high revs on the street his car should be crushed and his license taken away for life... having said that i highly doubt this person was.. this is my point. unless hes on the track a think upgrading a sump is a waste of time.

tom9999 Posted February 19, 2008 Author Share Posted February 19, 2008 (edited) Ok, its got forged pistons, strip,clean and inspect block, machine block, test and machine crank, resize conrods and rebush, ACl race bearings and mains, N1 oil pump 22000km on the motor blueprinted bottom end it had fresh oil 5w.30 castrol the car is just a street car, it was bouncing off the limiter abit. but when it happened i wasnt driving and i wasnt in the car. my 'MATE' the car was warm but when he got in and took off straight away and hit the limiter in first and 2 min later it when he came back it was F*C*ED also the car had not been tuned so it was running rich as on about 20psi Edited February 19, 2008 by tom9999 Link to comment https://www.sau.com.au/forums/topic/206613-r33-gtr/page/2/#findComment-3657627 Share on other sites More sharing options...

GTR-32U Posted February 19, 2008 Share Posted February 19, 2008 quick question...Did the oil pump survive the thrashing ? My thinking is that maybe the oil pump died from the huge revs and this caused you to spin the bearing....

N1GTR Posted February 19, 2008 Share Posted February 19, 2008 Ok, its got forged pistons, strip,clean and inspect block, machine block, test and machine crank, resize conrods and rebush, ACl race bearings and mains, N1 oil pump 22000km on the motor blueprinted bottom end it had fresh oil 5w.30 castrolthe car is just a street car, it was bouncing off the limiter abit. but when it happened i wasnt driving and i wasnt in the car. my 'MATE' the car was warm but when he got in and took off straight away and hit the limiter in first and 2 min later it when he came back it was F*C*ED also the car had not been tuned so it was running rich as on about 20psi Do not drive their cars. Reciprocity will be working to your advantage if you dont drive their cars. Seriously Sounds like there was a lot of limiter involved, first place to start is the oil pump Before buying new parts though, strip the motor down and see whats ok and whats not, then spend the money Link to comment https://www.sau.com.au/forums/topic/206613-r33-gtr/page/2/#findComment-3658710 Share on other sites More sharing options...

infamous_t Posted February 20, 2008 Share Posted February 20, 2008 it was bouncing off the limiter abit. but when it happened i wasnt driving and i wasnt in the car. my 'MATE' the car was warm but when he got in and took off straight away and hit the limiter in first and 2 min later it when he came back it was F*C*ED Your mate wasn't getting enthusiastic with chucking nuts by any chance was he? This can cause the same sort of oil starvation issues that track cars would come up against. High rpm would of filled the head with oil if no restrictor was in place. IIRC some ppl have mentioned recently some N1 oil pump failures recently... Sump baffles + oil gallery restrictor + aftermarket oil pump should be your new friends IMHO Link to comment https://www.sau.com.au/forums/topic/206613-r33-gtr/page/2/#findComment-3660933 Share on other sites More sharing options...

monga Posted February 22, 2008 Share Posted February 22, 2008 cheap option, pick up at rb26dett for around 3-5k then drop it in, cost 5-6k job.

mattymagoo22 Posted February 23, 2008 Share Posted February 23, 2008 everyone assumes its the oil pump! A lot of times it is, particularly on RBs, however, I've seen more engines spin bearings due to detonation like Proengines suggested! If the cars had a fresh build and has 23000ks on it and has been pinging the whole time due to a bad tune or even crappy fuel something has to give! In this case forged pistons aren't as likely to crack a land and the shock of detonation will overtime hammer the bearing flat and then the crank may pick it up(most likely at the time between the violent resonance when launching of the limiter when driving your friends GTR like you stole it) And a good engine builder will be able to confirm if in fact it was pinging just by looking at the bores. Hope you get her fixed. Link to comment https://www.sau.com.au/forums/topic/206613-r33-gtr/page/2/#findComment-3668773 Share on other sites More sharing options...
tom9999 Posted February 28, 2008 Author Share Posted February 28, 2008 ok so the motor has been pulled apart and by the looks of things it had been built incorrectly and they have cut corners!!! it was the third bearing in. its now getting new H beam rods new forged pistons blueprinted bottom end MLS gasket and etc Does anyone know how much boost i can run safely Link to comment https://www.sau.com.au/forums/topic/206613-r33-gtr/page/2/#findComment-3683258 Share on other sites More sharing options...
