I'm in the final stages of my oil system and wanted peoples advice/ideas

Ill be running an external single stage pump

Sump is going to be a custom alloy baffled and high volume setup that iv designed myself it will have fittings for oil pump, catch can breather, front oil return from head, rear oil return from head

Vct will be blocked off with 1.2 restrictors in the block and drilled out returns in the block

Oil cooler is currently set up from factory oil filter but that was where I was going to put the line for the oil pump is that the best place to put it?

engine is a rb25/30

I'm going to have a mesh cage kind of thing around the pickup pipe and a micron filter in the fitting and iv got a filter relocation kit in the cooler line would that be enough?

I'm mostly worried about the best place to plumb the oil back into the motor from the pump at the moment

Not sure if this really is an issue or not, as it's not my first hand knowledge, but when talking to my machinist when welding up my vct feed, he mentioned pre neo rb25s use that feed to lube the front cam bearing and that he has seen a bearing destroyed as a result of just blocking up the feed. (neo head vct is different) If you look at this thread http://www.skylinesaustralia.com/forums/topic/251669-rb2530-rb30det-vvt-internal-oil-control/ the photos half way down show what I am talking about.

I was planing on just welding the port on the bitten of the head were the oil exits and grub screwing the solenoid hole from what I understand the cam bearings will still get oil from the head it just won't be able to get out the bottom if that makes sense

Well if it was me I would be checking tht after you weld it it does actually get oil supplied to the front bearing, easy to do with some compressed air. An easy check to prevent a serious problem, and if it doesnt get lube drill out the plug like in the thread, easy fixed!

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
