Rb26 Engine Number Identification

[agraciev]

Hi guys,

Was wondering if anyone could help me identify my rb 26 engine number.

Engine number is

RB 26

R

701107X

I've tried to search the net to see what the R & X stand for but there isn't an exact answer.

Also attached a photo

Thanks guys

No photo.

What is it you want to know about your motor?

[agraciev]

Just trying to figure out what the "X" & "R" represents

[r32-25t]

There was a recall done on rb26 blocks at one point and I think the X represents that it was done

Does the engine code tell you if your crank suffers that oil pump failure ? let me see what my code is.

[Tim_zenki]

well i dont have permission to post image,odd, but code is 025351A

[agraciev]

Its real strange, i was told the first 3 numbers on the engine number "701" indicate that its a later model Rb26(2000's model & up)

But could have just been a recall motor which could explain what the R stands for, Refurbished maybe?

lol, earlier model rb26 is a 89 - 93 model

[agraciev]

*Later Model* My apologies

Really all you should be caring about is if you have a 05U or 24U or if you are very lucky a RRR stamped on your block.

mine is a 05U

Nothing special

[Tim_zenki]

yeah but does that mean it has that oil pump gear problem on the crank? i already knew it wasnt anything special lol

Who knows

Keep the revs sane and keep off the limiter. The engine has been going for a couple decades, no reason why it should just destroy itself if driven with a little respect.

I looked into this before and it seems the first number may indicate the year (circa 97' block), and the R indicates rebuilt / replacement block fitted.
