Hey guys, can somebody please explain to me what all these codes '26dett, 20de, 25det' mean. Im really really confused . So I would really appreciate it if someone could spare some time and explain it to me.

Thanks a lot for helpin.

26dett => 2.6ltr, Dual over head cams, Efi, Twin Turbo

20de => 2.0ltr, Dual over head cams

25det => 2.5ltr, Dual over head cams, Efi, Turbo (single)

Thanks for helping me out mate.

I've heard it means Race bred dont know if its true or not.

[paulr33]

false it doesnt mean race bred. its just the skyline engine code. sr is used in the silvia/200sx range and so on. they dont have any meanings

Why do ppl assume that a Japanese designed and manufactured product has an English name :lol:

In all honesty i have no idea what the RB means. But i do know that all RB engines are an "in-line" 6 cylinder engine. Another English name for RB could be Rail Block .

I can understand where Youre coming from But all Japanese Motor Codes are English names Ie T stands For Turbo D for dual Cam and so on and so Forth

"D" , "E" and "T" are universal codes, used by all manufacturers

so whats a 4-agze then?

Though it is true that the japanese provide an english code for their engines.

Z is supercharged in the toyata Line Up But Later on this Messed up with NA engines also containing a Z so they Just added another Z for supercharged engines that already had a Z lol if that makes sence

[ebola]

Uh huh. Each manufacturer can create their own scheme.

sine we all like nissans, rb, vg and sr mean nothing, they are merely series numbers. If they ever did stand for something, its long lost now.

I know (some) toyota engine codes (and goole knows the rest - google know all....), but didn't know they messed them up.

right

lets sort all this out for ya

rb20e -> 2 litre efi

rb20de -> 2 litre dual ovc efi

rb20det -> 2 litre dual ovc efi turbo

rb25e -> 2.5 litre efi

rb25de -> 2.5 litre efi dual ovc

rb25det -> 2.5 litre efi dual ovc turbo (with or without vvt - depending on year of engine)

rb26dett -> 2.6 litre dual ovc efi twin turbo

rb30e -> 3 litre efi

rb30et -> 3 litre efi turbo (the rb30e with a turbo - done by holden for the vl commonwhore)

rb30de -> custom hybrid of rb30e and either rb25de, rb25de with vvt or rb26dett heads efi

rb30det -> as above with turbo

hope that helps if u didnt already work that all out urself

Nissan makes engine identification easy, as all the letters and numbers have meanings.

RB = series of engine - don't think it means anything in particular

20 / 25 / 26 = capacity (20~1998cc / 25~2497cc / 26~2597cc)

D = Double Overhead Cam (or DOHC)

E = EFI (Electronic fuel injection)

T / TT = Turbo / twin turbo

So a RB25DE would be a 2.5L Double Overhead Cam with EFI, non-turbo.

Hope that helps
