Although the SDU site does say it, I wouldn't believe that it has to be true. They also get the power figures wrong on some of the Skylines which is pretty straight forward stuff. I don't think it's meant to be the definitive Skyline / RB guide, just general advice.

I had also heard the 6 cyl closed deck theory too, Abo Bob. Can you think of any other Nissan engines with common letters? All I can think of at the moment is the RD28.

does it have to mean anything...it is just an engine block designation.

All you have to know is the B in BNR32 is 2600, N is 4WD+HICAS (HNR32 has HICAS) and R32 is just that Skyline model/shape, similarly BCNR33 but C is now used for HICAS as this model ENR33 didn't have HICAS. In the R34 models the HICAS label was completely abolished for all.

B:RB26, E:RB25, H:RB20DE, F: CA, YH:RB20E

another site that thinks race breed

RBxxDETT stands for

RB = Race Breed.

xx = Engine capacity to the nearest litre. 20, 25, 26 and 28 are used.

D = Dual overhead cam.

E = Fuel injected.

TT = Twin turbo.

RB = Inline straight 6 code

just like SR, CA, VQ and VG all mean the type of engine.

The idea that RB means Race Bred is an abosolute pile of rotting shit because there exists an RB24S... inline straight 6 carby engine. Its about as race bred as my left testicle. Made from 11/88 to 04/90 (so it predates the RB20DE or RB20E) there was also an RB30S which was put into Patrols from 09/88 to mid 1991. Since when are Patrol engines Race Bred?

I've collected an article by the dude who chaired the development of the RB20DET and the RB26DETT engines, and it makes no mention of "Race Bred". These two engines were supposed to be the race winners in the Nissan stable.

The closest thing I've ever come to a meaning put to it on any japanese documentation is by a tuning company that called it "Race Box" but I doubt its what RB stands for, moreso an interpretation just like "Race Bred".

then why is it not called a BR? instead of RB. The japanese engine manual shows you how to decode the transmission codes and the Engine codes, and all it says for RB is Inline Straight 6.

R = 6 cylinder, closed deck.

B = Gasoline application using cast iron/nickle based block.

S = 4 cylinder, closed deck.

R= Gasoline application using sand-cast alloy based block.

K = 4 cylinder, closed deck.

A = Gaslone application using sand-cast iron based block.

Q = 4 cylinder, open deck.

R = Gaslone applcation using die-cast alloy based block.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
