N1 Block With A "r"

[maxspd]

I got an 1990 r32 gtr, was wandering if it was possible to know what engine my car was from..side of the block says 24U..so i assume its an N1 motor.r32?r33?.r34?

..and one thing that has me stumped is looking at the engine number ,in between RB26 and serial number there is a little R stamped. Everyone i spoke to has never seen it or heard of it... looks like this :

RB26

--------------R

060643A

without the slashes..

I also took the rocker cover off and noticed that the head bolt has a little dot on the rim of the hexbolt..all the ones ive seen are smooth.

thanks guys.

dude! that would have to be one of the bluriest pictures I've ever looked at!

I'm pretty sure the R is on all N1 blocks. the GT blocks have RRR. Though someone with more block knowledge that me can confirm it.

sorry about the photo, camera was really crap and too close to focus. il get some better photos up.

Ive looked at 5 n1 blocks, but they dont have a serial number on block. Was told if you order a block new from nissan,it has no serial number and the ones i looked at has no "R". So i assume its a factory N1 engine but out of what??32,33,34?

Is there a way to tell with the serial number?

thanks.

i didnt know you could check engine numers with fast..hmm..i could post the vin ad model number but im pretty sure the motor is not the original. This car is a bit funny, had a factory exhaust on ( brand new). high pressure intercooler hose clamps, huge alloy radiator with built in oil cooler,front subframe is all drilled out ,high boost setting on the hks evc was at 1.5bar?!? and when the car arrived from japan the clutch was completely destroyed..nismo twin plate. So it just raises suspicions to what it had in japan or what the capabilities of this motor is.

somebody must of seen this " R" before..no one in nz has... = ( , and not one reply from the gtroc forum. Its one of those things that annoy you until you can find the answer...= ).

SOUNDS PRETTY COOL. but its just a block. if your not making over 700hp it really doesnt matte.

being 06...... engine number id say its a 33. a early one.

Finally were getting somewhere..thank you! So an r33 motor.. Spoke to someone today and he told me hes only ever seen that head bolt on r34 motors...so hmm..

I got a street r32 that i ve done evrything to , except motor wise, so was thinking if this motor was up to spec, might swap it over..

700 hp at crank is the goal running 2530's. more than enough for me for the street. Trying to save money where i can for my drag car.should run this season. That car runs twin 3540's ,motec 800,adl pretty much everything under the sun. 1200hp and mid to low 8 is the goal..should post some pictures..not blurry ones..haha. = )
