Nissan Engine Series Meanings

[DeathBy240SX]

I read somewhere that the RB stands for Racing Breed. Is this true??? If it is what to the other codes mean???

[nomuken]

i don't think the first letters of engine names (SR, RB, CA, etc.) are acronyms. they're just used by Nissan to designate the engine series/model. the other letters/numbers in the engine name definitely have meaning, e.g.

SR20DETSR = The engine model (SR, CA, RB, VG etc)20 = The capacity of the engine which in this case is 2.0LD = Double overhead cams (aka "Twin Cam")E = Electronic Fuel InjectionT = Turbo

Other symbols include:R = SuperchargedTT = Twin turbo

[DeathBy240SX]

I am aware of all those meanings and I always assumed the series names were just that, series names for classification only. But some guy on eBay claims it stands for Racing Breed. I think its BS but just wanted to make sure.

[89240sx]

I would think they would stand for something.... I could be wrong but it would be logical that they stand for something wouldnt it?

[driftaholic]

RB = Racing BreedCA = Competition AspectKA = Kamikaze AspectSR = Super RadVG = Very GoodVQ = Very QuietFJ = Fantastically Japanese

[krazy skwerel]

SR = Super Rad

Well damn I guess I will have to get an SR after all. Honestly when we made the name I never thought of that.

[Onizuka]

RB = Racing BreedCA = Competition AspectKA = Kamikaze AspectSR = Super RadVG = Very GoodVQ = Very QuietFJ = Fantastically Japanese

VK = Verified kinglynessVH = Very HotQR = quality radness

in all seriousness they dont mean anything, its just the engine type.

[I30T]

yeah, pretty much.

has wahat the engine codes and the VIN numbers mean.

[s13sr20chris]

it could just be a coincidence, but think about all the v engines having a v. you got vq, vg, vh, and vk.

[DeathBy240SX]

Good oberservation. Thats a start.

[nametakennow]

SR= single row?CA= cool aisle?KA= king ape?RB= rad bada**?

[driftaholic]

and CA, KA, and GA end in A

[krazy skwerel]

Hmm so A=4cyl. Wait not that doesn't work fj damn my logic doesnt work.

[driftaholic]

SR = 4 cyl, so not necessarily

think of number of cylinders, inline, V shaped, maybe we WILL figure this out

<---- looky looky! my evil post

[DeathBy240SX]

But FJ doesnt really follow the rules as it is a DOHC, but is still the FJ20E(T)

someone analyse this list and figure it out

[s13sr20chris]

holy crap. i have a "complete" list of nissan/datsun engines that is issued by nissan to my dealership and it doesnt have some of thoses. a lot of those are jdm motors i guess. i would point out that the qr is a product of the sr and the ka. the ka is a product of the l and the s. im not sure, but i think the ga is a product of the a with the qg obviously being a product of the ga.

[driftaholic]

oh i noticed all the Vx series are V blocks w00t

I thought that was common sense....

[Cold_Zero]

QR= 4 cylinder.I dont think that they have to have a meaning. It would be kewl.

[MasterMan]

RB= rad boobies

[240_2NR]

maybe KA, CA, and GA might have A because of its iron 4-cyl block? since the SR is alumnim. if so what metal is the FJ made out of, maybe its missing the D cause its got top feed injectors not because of twin cam? like ka24e has top feed and and ka24de has side feed

[MOTOP]

end of R=4 cyl

KA ?

[240_2NR]

end of R might be because its made out of aluminum like SR. QR?

FJ doesn't have "D" for drivetrain type because it was the very first Nissan engine to have DOHC. The "D" designition had not been official at the time of release of the engine.

As a side note, a diesel engine is denoted by a "D" following the engine series but before the displacement. So a theoretical diesel SR20DET would be a SRD20DET.

Also, no letter for fuel delivery designates carbourators.

And finally, engines before about 1965 did not follow the engine naming code that exists today. The very first Nissan engines was the G and B engines. Every engine after that was the G2, G3, etc. After the list of engines became hard to decipher, they began using the current naming scheme.

If somebody can host this *.xls file for me, I can upload a list of engine and chassis codes for every Nissan ever made (or nearly anyway). I can't upload excel files as an attachment in the forums though.

hold up now. for a short time s designated carb. in late 80s when most everything was fuel injected.

S designates carb only when there is a fuel injected version of the same engine.

For instance, the L24, used in the 240Z has no letter for fuel delivery type. However, the E16S, used in the Sentra, uses the "S" designation because of the optional E16I, which was throttle body fuel injected.

Also, to confuse even more, a designation of "B" is two differentiate between 2 configurations of the same block design. An example of this is the L20, an I-6 used in the Skyline, and the L20B, an I-4 used in the 510. Both are "L" series blocks, but one with 4 cylinders and one with 6.

If somebody can host this *.xls file for me, I have compiled an excellent list of engine codes to learn from.
