mrgee2jz Posted December 8, 2009 Share Posted December 8, 2009 Hi there everybody, i was just wondering if we need a baffled sump? I have heard of and seen the result of oil surge whist racing. I have not yet seen it on a supra. The thing i am worried about is that i have a 2jz in an e30 and using a soarer sump which has the main bowl of the sump towards the front rather than the back, now on acceleration, which i have a lot of, will all the oil fly to the back? or am i safe??? and how about cornering?? I am currently rebuilding the engine AGAIN so i would like to do this now if needed. Regards Gary Quote Link to comment Share on other sites More sharing options...
Digsy Posted December 8, 2009 Share Posted December 8, 2009 Most stock oil pans are designed to keep the oil under control at up to 1g cornering and probably about 0.5g accelleration / deceleration. I've been involved in sump surge testing and development for cars that you would never dream of trying to corner at 1g. I would say that the oil control in a car that was designed to have high performance from the get-go would be pretty good. Quote Link to comment Share on other sites More sharing options...

Paul Whiffin Posted December 9, 2009 Share Posted December 9, 2009 We dont seem to have any oil surge problems on the track in our cars, if we were running on slicks that might be a different case. If you really want something, Twins Turbo in the US do a dry sump system, not cheap though. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 9, 2009 Share Posted December 9, 2009 I do an oil separator rail for both early and late model 2JZ-GTE used for track work. £75 each plus carriage. Bolts under one side of the main cap bolts or studs and removes a lot of windage oil from the crank. Engine out job to fit. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted December 9, 2009 Share Posted December 9, 2009 Well, I have made one, there's not exactly a queue down the road for them Given an order for say ten I can have them laser cut and they'll be cheaper. Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted December 9, 2009 Share Posted December 9, 2009 I'll have one off you next time I do an engine rebuild, probably going to be building up another engine in the next few months, I'll let you know in advance. Ta Quote Link to comment Share on other sites More sharing options...
