Hi

Am just fishing atm but am looking for a good used RB30 bottom end

Block, crank and cradle is about all I need but if a short engine then so be it

If possible would like to find a good block on standard bores and a standard sized good unground crank

Block does need to be the right type with oil, water and lower tension provision already in place mind!

I have someone who will help collect/ship it to me, so can now try find a good usable unit

Preferably near or around central coast/ Sydney area?

As for price let me know what you have as don't mind paying a fair price for a good sound unit

cheers

Hey mate I have a complete RB30 in newcastle that has all the correct provisions for turboing if you are keen. But I am not home for 3 weeks. Located newcastle.

Could be up for that if you know the bottom end to be all good on standard size bores and crank ?

Pm me a price if you could as I will need to confirm collection is ok still before I can deffo say yes

Came out of my mates running R31, bottom end started to get a little noisy and he swapped an RB20 into it. Pulled the bearings and sure enough they had just started to go. Can confirm absolutely it's virgin bored and standard crank. Can also supply pics of bearings if they are still on my phone.

Ok if its no grief and you know the crank to be 100% good still and deffo unmarked then it could still be a go

If it is scored or picked up am not up for that though. Post some pics of the parts if you have them and an idea of cost?

tbh I don't want to get into using a crank that's been ground or needs it mind.

Fussy sure but having it shipped over here it needs to be right first time, sure you can understand

      Ceramic turbine damage to engine - what did yours do?

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
