I hear so many conflicting opinions about this. I just rebuild my engine with wiseco forged pistons and my mechanic has has the car for a week because he wants to put some k's on the engine. is it really necessary?

Not at all.

Bed the rings on the dyno, tune it up.

All my motors have been done this was, as have countless others. If the motor is built right from the start you shouldn't have issues.

Had this discussion with Paul earlier today about my motor - thats his prefered method too. He just said the thing not to do is don't let the mottor idle to bed the rings in

Yes it is

And the oil is critical ( type and prelube on cams etc) i would never flog a brand new engine build unless your wallet is thick and racing required it !!

yes racing a quick run in to seat rings and bearings , check for leaks etc , heat cycle it a few times before a caning it

But have built many engines and popped them into race cars after 5 min of checking for leaks off to the races without drama and it lasted most of the season before melting a forged piston ( fuel related failure )

i was always told you had to bed them in for a couple thousand kays :/

My 34 GTR is almost done now and i have been told by my mechanic he wants me to drive it for about 1000km then bring it back to him to make sure its all tourqued up and that sort of thing before i give it some.

    • I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
    • I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.  
    • Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
    • Yep that is correct. It allows you to adjust the short throw range from what I can tell
