240Z_Master Posted March 15, 2006 Share Posted March 15, 2006 Does anyone know the genuine Nissan part # of RB30 crankshaft? I think you have to have an Aussie with access to Holden's to find that one champ. Quote Link to comment Share on other sites More sharing options...
sooley Posted March 15, 2006 Share Posted March 15, 2006 Just type in RB30 on a search engine and you will find something, usually to do with a Holden Commodore VL Quote Link to comment Share on other sites More sharing options...
KAZU Posted March 15, 2006 Author Share Posted March 15, 2006 what I want to know is nissan part number. nissan skyline with RB30E made in Australia between 1986 - 1990. sold in Australia, New Zealand and Papua New Guinea. VIN code is CJR31 (sedan) or WCJR31 (wagon). Quote Link to comment Share on other sites More sharing options...
AKWIKZ Posted March 16, 2006 Share Posted March 16, 2006 Unfortunately, even if you had the crank, it would not do you any good. The RB30 uses a block that is 1 inch taller than the others. If you were to use the crank in a shorter block, you would have extreme rod angles that would not handle any kind of power. Not to mention that you would have pistons that stuck out the top of the block. Brian Quote Link to comment Share on other sites More sharing options...
KAZU Posted March 16, 2006 Author Share Posted March 16, 2006 Brian, thank you for the input but I would't have such trouble. I must say the crankshaft will be fit in an alternate block, aka L28. Quote Link to comment Share on other sites More sharing options...
KAZU Posted April 30, 2006 Author Share Posted April 30, 2006 gotten a Nissan Fast CD (AR). RB30E crankshaft: 12200-67S06- Quote Link to comment Share on other sites More sharing options...
Stealth-Z Posted May 2, 2006 Share Posted May 2, 2006 Brian, thank you for the input but I would't have such trouble. I must say the crankshaft will be fit in an alternate block, aka L28. Out of curiosity I compared the RB30 crank I have with an L28's. Journal sizes are not even close. The L28 rod's will not fit. Don't waste your money on one to put in an L series block.

Narrowed stock or custom billet rods with VG30 rod bearings may be needed, though. Quote Link to comment Share on other sites More sharing options...

L series have a wider width. Also you will be dealing with the oil pump, timing gear and harmonic balancer problems. The RB crank has a smaller diameter so the L28 gear will have about a quarter inch play. Narrowing stock rods would be iffy in my opinion. There would be alot of metal being removed and structural integrity would be affected. Quote Link to comment Share on other sites More sharing options...
