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.

have you nissfast the number it may give a little more insight?

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. = )

      R34 Gtt Wheel Offset Advice

      By GTSBoy · Posted

      I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.

      It still combines inches with mm, especially when you have .5 inches involved, and mm and inches that can go in either direction. This would give a clear idea on both sides of the rim, right away, with no arithmetic. Even better if somebody gives you the dimensions of the arch of multiple cars. i.e GTR may be 125mm, a A80 Supra may be 117mm, or something along those lines. Yes, you can 'know' that going from a 10in rim to a 10.5in rim with the same offset moves both sides about 6mm, but you still have to 'know' that and do the math. Often it's combined. People are going from 9.5 +27 to 10.5 +15. You may do the math to know it, but if it was going from (I had to go look it up to be sure) 241mm/2 - 27 - 93.5mm from the center line to (more math) 266/2 - 15 (118mm) from the center line. Versus 93mm vs 118mm. It's right there. If you know you have a GTT with 100mm guards you can see right away that one is close to flush and the other absolutely won't work. And when someone says "Oh the GTR is 120mm" suddenly you see that the 10.5 +15 is about perfect. (or you go and buy rims with approximately 118mm outward guard space) I think it's safe to say that given one of the most common questions in all modified cars is "How do offsets work" and "How do I know if wheels will fit on my car" that this would be much simpler... Of course, nothing will really change and nobody is going to remanufacture wheels and ditch inches and offset based on this conversation :p We'll all go "18x9+30 will line up pretty close to the guards for a R34 GTT (84mm)" but 'pretty close' is still not really defined (it is now!) and if you really care you still have go measure. Yes it depends on camber and height and dynamic movement, but so do all wheels no matter what you measure it for.

      But offsets are simple numbers. 8" wheel? Call it 200mm, near enough. +35 offset? OK, so that means the hub face is that far out from the wheel centreline. Which is 2s of mental arithmetic to get to 65mm to outer edge and 135mm to inner. It's hardly any more effort for any other wheel width or offset. As I said, I just close my eyes and can see a picture of the wheel when given the width and offset. That wouldn't help me trust that a marginal fitment would actually go in and clear everything, any more than the supposedly simple numbers you're talking about. I dunno. Maybe I just automatically do numbers.

      Sure! But you at least have simple numbers instead of 8.5 inches +/mm, relative to your current rims you do maths with as well, and/or compare with OEM diameter, which you also need to know/research/confirm..
