Looking for a full set of brakes. Calipers, rotors and pads. Can buy rotors and pads separate. Also looking for rear turbo hubs or wheel bearings. will pay post to SA.

Hi guys. Feel free to delete this post if it's already been asked but I cannot find anything on google showing how people calculate the oil clearance without bearings installed. I have an idea of how to, but I just need someone to confirm my calculations for my bearing/oil clearances before I buy the bearings. This is my first ever build and first ever RB30/25. I've never done something like this and I'm trying to do as much labour as I can before I send it to the machinists to save $$, so bare with me. I have measured the journals with a micrometer and mains + big end tunnels with a bore gauge (without bearings installed). I'm going to be using ACL Race bearings for mains and big ends. I need to know what bearings to choose for my desired oil clearance. Now here's the thing. By looking at the ACL RB30 bearings spec page, the thickness of 1 standard big end bearing shell is 1.503mm. Am I correct?. And 1 main shell = 1.827mm. So, if I were to go with a 0.025 oversized bearings, the thickness of one 0.025 big end bearing shell would be: 1.503 + (0.025/2) = 1.5155mm. Correct? Because it's adding 0.0125mm on each shell to make the diameter of the 2 shells 0.025mm bigger right? And thickness of one 0.025 main bearing shell would be 1.8395mm. Ok, so calculating oil clearance would be tunnel OD minus the thickness of 2 bearing shells, then minus the crank shaft's ID to get oil clearance right? So, for example my #1 main tunnel OD = 58.682mm. If I used standard main bearing, the thickness of 1 shell is 1.827mm. My #1 main crankshaft journal ID = 54.962mm. So calculating the oil clearance would be 58.682 - (1.827x2) = 55.028 - 54.962 = 0.066mm of oil clearance which equals to about 2.5 thou. If I were to use 0.025 oversized then I would calculate it like: 58.682 - (1.8395x2) = 55.003 - 54.962 = 0.041mm of oil clearance (1.6 thou). So calculating all my oil clearances using standard bearings on the mains would be 0.057mm to 0.077mm (2.2thou to 3thou) of oil clearance. Big ends oil clearance using standard bearings = 0.032mm to 0.053mm (1.2thou to 2thou) Calculating oil clearance using 0.025 oversized bearings: Mains = 0.032mm to 0.052mm (1.2thou to 2thou). Big ends = 0.007mm to 0.028mm (0.3thou to 1.1thou). Calculating oil clearance on big ends using HX (thinner bearing shell thickness of 1.49mm) would be = 0.058mm to 0.079mm (2.3thou to 3.1thou). Another question I have is what would be the best oil clearance for an RB30/25DET Neo that will only be used for street use with about 300kw (max) with a crank collar and RB25neo oil pump limiting the revs to 6500 or 7000rpm (with the correct oil restrictions in block). I might shim the oil pump spring to give it more pressure if needed. My goal is just a responsive and reliable streeter engine that will last years. I've read somewhere that someone qouted Qubes saying that he recommends 2.5thou oil clearance on the mains and 2.2thou on the big ends for RB30s. Can someone confirm this? So should I go with standard ACL Race bearings on the mains and standard on the big ends or HX on the big ends (3.1thou max though?). Thanks.

Hi everyone. I took my sons 25GTt fo a wheel alignment today.. Unfortunately it could not be done due to worn wheel bearings.I have new bearings on the way. Questions: Has anyone replaced front wheel bearings? Is there any literature on how to change them? Can the front bearings be regressed as a temp measure? My experience is with early ford and holden tapered bearings, these jdm cars are a whole new ballgame. Appreciate any advice and push in the right direction..

Really cheap 5 Stud complete front Hub assembly incl bearings (off R33 GTST). ($15) + some other bits. $15 each for the front hub assembly Bearings were good when they came of car 1 year ago. Pickup Campeltown NSW. Pm with your number for pickup info Also have for sale hicas 4ws rack $30 Rear seat $10 Ac condenser $20 Headrest $10

Up for sale is a brand new ACL conrod bearing kit for an RB20DET motor, 45mm big end diameter. I had ordered these for my 20DE Neo but turned out the Neo uses a smaller crank journal for the rods (42mm) as opposed to the regular RB20. I paid $80 USD for these but I am open to offers as I need these gone. Will ship internationally, located in Bulgaria, EU. I accept Paypal, Revolut or Bank Transfers.

Which bearings for Forged Conrods rb25 Hey guys bought myself a set of forged rods for the rb25 build and I know the process for selecting bearings when it is stock rods but what is the process for selecting bearings for a set of forged rods? Do I need to get the crank linished? Or...... I read conflicting stories with conrod bearings and that was you only need the numbers off the crank for rod bearings and the. I read you need the number off the rod aswell as the crank now I'm confusedddddd please help cheers boys

all items located in blakeview SA - RB25DET motor that has been previously opened as I intended to forged rebuild it, I had to move interstate so I loosely bolted it back together as the moving company wouldn't move an engine but they would move the car with or without it. the engine does need to be rebuilt and will come with new rings and bearings, the intake manifold, throttle body, nismo 555cc injectors, a tomei cam gear on the exhaust side, gates racing timing belt. the motor was on 107xxxKM before it was stripped. the motor DOES need to be re built $700 ONO or 800 with crane and stand I also have a few other parts as well: -extreme 6 puck solid button clutch with a extra heavy duty pressure plate, used but in near new condition - $300 ONO -SPOOL H beam forged conrods to suit RB25 and 26. - $500 ONO - SCA engine crane and stand, for both $250 ONO -standard RB25 coil packs. $50 ONO - R33 RB25 engine loom. $50 ONO - all off RB25: starter motor power steering pump alternator aircon pump flywheel R32 engine mount brackets STD AFM cam angle sensor clutch fan ↑ all $20 each or make an offer I am open to offers but please don't waste my time with ridiculous offers, feel free to ask any questions PM me on here to get in touch

Hi everyone, I have the following up for sale as i no longer need it. As far as i am aware it only completed a few Dyno runs and not a cent was spared. The following is what was done: RB25 Motor Ross Racing Pistons Engine Gasket set incl. steek head gasket set Race Series Big End Bearings Race Series Main Bearings Welsh Plugs, big and small Serviced Cylinder Head Port and Polish Cylinder Head Machin block deck surface, balance crank and linish, balance pistons, balance rods, machined flywheel, removed aluminium plugs and replaced with steel plugs total cost when everything was done was over 6K (i have the reciept) $6,384.84 including labour etc Im chasing $2200 firm. Anyone who knows about building engines would see that the racing pistons costed 1300 so trying to get rid of it cheap. Any questions please ask. (as far as im aware it will need new oil squirters) thanks, Tom
