It may be a silly question but for my R30/RB26 build what oil level do I need in the oil pan? I fitted an RB26 dipstick and tube to the block and it has a sump adapter on 10mm thick so will my max oil level be 10mm lower than the max marked on the dipstick or because I have the sump adapter am I okay (or should I aim) to fill it up to the max mark?

Cheers

Lee

I don't know for sure, but the max oil level is only to stop the oil rising too high, so with your 10mm adapter, you should be fine to add oil to the max level. You just have 10mm more depth to you oil pan now! Maybe have a looky at the RB30 dipstick and see if they reach down the same amount or if they are different.

That was kind of my thinking but I don't want to be wasting good oil if I don't need that much!

Now that I am running an RB26 sump and dipstick tube if there is a difference with the RB30 that doesn't really help me. Thats why I swapped to all RB26 bits so it matched the sump.

Thanks guy's, Insurance sounds good to me! I meant waste in the sense of if it tries to blow it out cos the level is too high.

So that makes the new oil capaity around 6.5 litres? Just checking.. Plus I need about another 1/2 litre for my oil cooler too I reckon! It's 25 row?

Thank you

HI mate

I found that with a 10mm adapter plate, a bone-dry engine (ie assembly lube only -have you just rebuilt?) and an ancilliary oil cooler (with all the relocation lines) plus filling the oil filter, you are looking at 8 litres or more per oil change.

Yeah, I know - I was pretty surprised too. Others have suggested they are at 10 litres..

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
