RB30Z32 Posted April 14, 2008 Share Posted April 14, 2008 (edited) Can anyone post up any pics of the mods to the oilways in the head & block. I'm just wondering which ones to drill out & which ones need opening/funneling out. Cheers Stu.

GreeceS13 Posted April 15, 2008 Share Posted April 15, 2008 SydneyKid there is a hole in the block near to oil return... Is it a good idea to return the oils from the head there?

Sydneykid Posted April 15, 2008 Author Share Posted April 15, 2008 SydneyKid there is a hole in the block near to oil return... Is it a good idea to return the oils from the head there? Depends on what block, generally speaking, no there isn't. That's why the suggested return is into the top LHS of the sump.

donkey Posted August 9, 2008 Share Posted August 9, 2008 hey there, just a question, ive read so much about the oil problems RB engines have, these cars arnt cheap to but, so much technology goes into development of these machines, and there seems to be about 6 problems with the oil side that sydneykid lists, why the hell have they not developed a better system of oil supply when testing their cars? or maybe nissan should have hired someone with a brain (sydneykid) to do the most critical part of a car engine????????

Ask Nissan??? If the GTR's were used and driven as a stock road car with no power mods etc, they would be fine 90% of the time. They did fix the oil pump drive from late R32GTR's onwards(thats about it). As soon as you push beyond factory specs and set limitations, that's where all these mods come in handy I'm sure.

Duncan Posted August 9, 2008 Share Posted August 9, 2008 I was lucky enough to see the inside of the engine that gibson motorsport built for kerry packer's car back in 91 last week. while they had made some mods, they didn't have: external oil return restrictor in feed to head (in fact they had opened both feeds!) wide drive on the oil pump expanded internal oil return at the rear of the block. I think it is fair to say the development that gary and the race team have done on these motors over many years, and they fact they have been willing to share the knowledge at no cost is very valuable to everyone on these forums oh, and it spun a bearing on its first track day....

Ouchhhh! That's expensive. How much was the engine back then....~150-200g? Dunc, what changes have been made on the engine/car that caused the spun bearing? Was there any new oil pump, was the rpm limit raised, stickier tyres etc etc?

Dazmo, what kind of dollar is it for your dry sump and is there anyway of fitting one into a rb with Aircond and power steering intact ?

GTRsean Posted August 12, 2008 Share Posted August 12, 2008 You drill the smaller round holes to 9mm right? I'm drilling mine out to 10mm, to match the head gasket. Diameter of one of the oil drain holes, where it steps to the larger diameter is 9.65mm, and gasket was 10mm.
