Now as I understand it the engine numbers are sequential for the rb26. 

EG stamped - RB26040100A is a 40,100 engine. 

 

Now they made between 1988 and 1994 43,834 R32 GTR's 

In 1994 they made 7,464 r32 gtr's. 

So if you have a ~37,000++ number RB26 it's "safe" ish to assume its an 1994 motor and a long nose crank ? 

 

The long nose crank being introduced somewhere in Feb of 1993.

found this on the forum , suggests I am in the range 

-----------------------------

From the segmented (potentially incorrect) information I've found that; 

Early R32: RB26000XXXX to RB26002XXXX 

Mid R32: RB26003XXXX (V-Spec I RB26-03XXXXX - Reference Classic Register)

Late R32: RB26004XXXX (V-Spec II RB26-042XXXX - RB26-045XXXX - Reference Classic Register)

Early R33: RB26005XXXX

Mid R33: RB26006XXXX (as per the engine in this R32 V-Spec II, which is what I'm concerned about from legitimacy perspective)

Late R33:  RB26007XXXX

Early R34 (2000+):  RB26008XXXX

I think you pretty much nailed it.

THANKS !

 

Sequential at times but overall Incremental is probably a better way to state it. 

Chassis numbers with Nissan's are like that too, jump when a change of some kind occurs. 

 

Bit of a surprise to find out that despite being a 32 RB26, it's most likely the better crank. 

 

Winner Winner.

Doesn't really do any good, especially without billet gears. The oem pump is crap. If it doesn't break, the screws holding the backing plate will come loose.

I think he's just happy that the crank doesn't have to come out of the engine in order to have a good (read reliable) oil pump.

Over the moon in fact.  Engine is coming out to put on a new enlarged sump. I planned on putting on either a new pump(Tomei / Nitto) or billet gears.   But a bit of waste of time if the crank has narrow collar.

 

Things spiral quickly, if crank is out, new bearings ... maybe new rods and pistons ... wait just rebuild the engine... oh but I should get an N1 block  .... 40k later  .... haha.

I've never seen this on a factory built RB26 have the screws come out, or gears break for that fact. Only once someone has touched the motor have I heard / seen it.   I've seen a few factory built Rb25's shatter gears but we talking high mileage extreme beating at drift track, constant limiter for a full season.  Well outside what it was built for.

Def happens. Happened to mine too. Have pics to prove. Super picky, I noticed the OP slowly dropping.

I can believe it if you're getting air into the pickup. Cavitation is tremendously destructive for pumps.

    • Nice one, I'd argue that the white S1 RS260 is certainly the best looking of the Stageas. And yes, fully agree on the forum situation. It's a bit of a shame, but at least SAU is a good place to be. I found the facebook groups to give me FOMO because people were trying to one-up each other and show off in some way. Feels much more natural here. There are people with seriously nice builds, but I can appreciate it rather than it making me question my life choices. Might be that people are more open with sharing how much work/money/suffering it takes to actually get there. 
    • Evening, wanted to pop in and finally register to say hi to everyone here on SAU!   It's been a while since I've been active on a forum, but back in the day I used to be relatively active on ClubLexus and other hobby-related forums. I'm glad to see SAU is still around, since with the advent of Facebook and Discord it seems forums aren't what they once were. As a recent new owner of an S1 260RS Stagea, I've found so many older guides and helpful tips from SAU that I figured I needed to join and say a grave thank you. My recent acquisition has only become legal in the US for the past year, and knowing that similar car enthusiasts from across the pond have already figured out the kinks and tricks to get these 25+ year old cars running well. I look forward to diving into more of the SAU forums as well as hopefully contribute some info myself for future posterity.   As a pic tax, here is one of the few good photos I have of my Stagea. I hope to get way more in the future!    
    • Is this where I say "Hey man my airbox cost me horsepower in my Naturally Aspirated Engine"? (I know you need them for legality in NSW)
    • 1.5mm alloy folded up, it will need a tweek, as the angled bend only got to around 45° as that was the max that the break press would get with the other bends, and I needed a fair bit more, but and the alloy is easy to bend too my will by hand once I trim the lower section out I'll Dremel out and form the angle and mounting point on the lower section when time permits  As for the lid, I'm looking at going a "cap", instead of a flat lid to hide the fixtures a bit
