its took 1/2 a sec off Rev210's 1/4 mile time alone.

as joel said the off boost acceleration just doesn't compare this thing rocks.

If you buy a RB25 Clutch its going to boltup to any RB25 Flywheel. (there 5 bolt by the way)

and likeways the other way around.

back okay from the shadows u can make out how deep the walls of it are.

on the stock flywheel that whole area is solid metal, to make an analogy imagine the pic as an empty cake tin (the ogura flywheel) the stock flywheel whould be the cake tin full.

It doesn't actually matter how light a flywheel is but where the material has been removed.

However a certian extent measuring the weight is a good indication.

Around the outside is where it affects inertia.

You could have 10kgs 5cm's away from the crank and it would rev quicker than if you had 5ks 15cm's away from the crank.

Its not so common with 6cycl's but with 4cycl's you will find if you remove to much material from the center of the flywheel you will get vibrations, nasty ones.

Still I can't complain for a Chrome Molly Flywheel for an extra $200 when fitting the clutch.

The rev's do drop really quickly now when free reving and is heaps quicker in matching rev's when pulling up hard.

    • Came across these Ganador reps and am wondering if anyone has used these/come across these ?  Seem to look like reasonably good replicas (shape wise) from what I can see. Ive been told by them that they are moulded to be exact copies of original Ganadors (but thats what every replica version will say) https://www.shiftperformance.com.au/ganador-style-mirrors-suits-nissan-skyline-r33-gtr Photos of them installed appreciated Thanks 👍
    • lol, yeah, and how gutted I am now I’m back over in Europe (actual Europe) and dealing with the nightmare of U.K.-Continental Europe bureaucracy.   Anyway, arrived in NL early January with the BMW, whilst the Skyline followed suit about a week later. Both cars ended up stuck with their relative importers for about six weeks. Since then, I made a trip to the Nurburgring with a friend and have since ditched the Skyline in the garage. This week, I finally managed to find a suitable shop to do an alignment so hopped on over to Germany to fix the miserable mess the local Netherlands shop conducted; the car was just not aggressive enough in the rear for my driving style - I found myself understeering a fair bit at the ring which was really a first for me with this car. Mis-matched F&R tyres can be held partly responsible - have now moved to F+R NS2Rs. One thing I’ve noticed is the 180kph limiter just does not cut it here. I quickly hit that (for the first time) in Germany on the autobahn. Japanese circuits are small - at least the ones that were near me. I rarely spent much time in 4th. After much deliberation with the HKS SLD, I have ordered Nistune from Matt. Whilst the Skyline has been gathering dust I got to learning the highly neglected BMW I bought in the U.K. was in fact just that, highly neglected. Took the ol’ dog down to Switzerland last weekend with a progressively deteriorating front end. It went from vibration during braking at highway speed on the way down, to vibrating non-stop on the way back. I’ve already fixed numerous engine issues - low oil pressure, f**ked injectors, incorrect coils and plugs, electric water pump. Still to do is a suspension and brake overhaul, rear subframe replacement and likely more ageing engine electrical components. But I must say, I love it. After so long with the Skyline, I really didn’t know cars could be so comfortable.    
    • Thanks. I adjusted my soft cut to 7600rpm and if I see I'm still making power there, I'll consider readjusting to possibly 7800rpm while on the dyno. 
    • Yeah not sure. I sourced another relay no problem, its definitely a relay according to Nissan parts, they used those specific relays on a bunch if cars around that time, but my two options are, find a behind dash wiring loom which is proving difficult, or get the current loom fixed up by the shop when they put my rebuilt engine back in, they are confident in their auto electrical abilities. Thing is my current loom has anti-theft stuff and GPS immobilisers wired into it so easiest option may be to just fix the current one to save ripping apart the immobiliser. 
    • Took it apart to get to the bearing found out i was wrong the bearing was pressed on to the diff side and the part i removed only had the bearing side, checked the bearing all looked fine took the shaft end to a shop and they recon it was movement from back and forth that made the marks and not rumbling about, so i just changed the seal and put it all back again.
