Hi, I'm rebuilding a blowned RB25DET engine basically for drift use with the following main components: 86.5mm CP forged kit ACL bearings Cometic gaskets OEM oil pump HKS 264 cams 9.0mm lift HKS GT2540 740cc injectors Splitfire coil packs APEXi Power FC My wanted hp range is nothing serious just reliable ~350-400 @ crank and don't want to rev above 7500rpm. I read very different opinions about oil control modifications. The most common advices are: - use the aftermarket crank collar. - use 1.25mm restrictor with OEM pump - block off rear oil feeds - drill out oil return galleries in head&block about ~1mm each - use a head to sump oil drain kit Lots of other ppl says it's all just stupid things, there isn't any trouble with the RBs oil control, and these mods maybe leave the head without oil ... Modifications needed only on seriously modified engines that will get high amount of G forces. So what's your opinion, what are the mods that definitely need to be done in ~400hp RB25DET? I had a 430hp RB26DETT (N1 turbos, HKS cams, Nismo bearings, IMPUL ecu) before in my JDM import PS13, and never had any troubles with the oil control. I used MOTUL300V oil overfill ~0.5-1.0L .To tell the truth I didn't open it while I owned, so I don't know It had wider crank collar or not, but there wasn't any oil drain uprated pump or smtg. Oil pressure was 6.5bar at WOT, and never seen under 2 bar at idle after drift use. Regards, Z

I'm just a drifter from Hungary, Europe. I had some AE86s in the last 10 years. I started drift racing at 2008 with Hachi (http://ae86.blog.hu - my old blog about the AE86 driftcar build up and racing events). 2009, I changed my loved hachi for a JDM import very fine built RB26DETT powered PS13 (from www.powervehicles.com). The car was really fantastic, but I never used her on competitions, just used on training days. 2011, I sold the Silvia and bought an R33 Skyline with blown RB25DETengine. I decided that I'll rebuild the the engine, prepare the car for racing and maybe I'll return to the racetracks. 1994 Skyline R33 GTS-T: HKS GT2540 TurboHKS adjustable actuatorHKS Front Mounted IntercoolerHKS cams and SprocketsNISMO flywheel APEXI Power FCSPLITFIRE coilpacksNISMO 740cc InjectorsGReddy profec b boost controllerMulti purpose turbo controllerNISMO Fuel PumpUprated Oil CoolerAdjustable fuel regulatorTurbo hard pipeOil Catch TankNismo clutchBLITZ Nur Spec Exhaust System CUSCO Catch TankCUSCO Brake Master Cylinder StopperIntercooler Hard Pipe KitAlloy Power Steering PotBLITZ SUS FilterZ32 Air Flow MeterGreddy Water Temperature senderNISMO 2WAY LSDOS GIKEN close ratio box CUSCO tention rodsCUSCO track rodsCUSCO camber armsHicas Cancel RodARAGOSTA coilovers Rear Tower Bar NISMO Front and Rear Stabiliser BarNISMO Front Stut Brase18" wheelsRAYS wheel nutsNISMO 300km/h Clocks Spec 2 Front End ConversionAero Stylingcarbon fibre bonnetDrift-R Rear SpoilerMOMO stering wheelBoost gaugeRecaro seat Bride seat console4 point Racing harnesses
