Well my clutch is on its way! Jim looked after me alot with price which was good of him , soon as its in I will get it tuned to its potential and head to drags hopefully with no explosions lol. Then fingers crossed I get banned for running sub 11 then no need to worry just cruises and hill climbs etc. I'm thinking if switching back to street tyres instead of semis to make an easier weak point in driveline but will keep u all posted

Good stuff :) Let us all know how you go! Make sure you fit it 100% to Jims specs ;)

Nismo copper mix twin plate all the way, drives like a factory clutch and know of one holding 475 at the wheels, including massive launches and been in the car for 8 years Also have the added bonus o

did Jim tell you it must be your driving style...

Are you saying the clutch recommended to you is a solid centre and not a sprung clutch? Solid centers are cops to drive and will eat gearboxes just because they are bored and they like the taste

what happened to you being a JB fan?

I got a Nismo and never looked back really, just so nice to drive.

Even had a Nismo die on me (after 500+ launches, 4WD helli's, 30k kms driving)... All it did was start to flare a little like a normal clutch wearing!

Well after a radiator hose issue it's all running now and to be honest it feels like a stock clutch! Zero noise and it can be slipped with no issues so providing it doesn't explode lol very happy with it so far and I was sick of the twin plate rattle but I was expecting some noise but there is really none, thanks jb

We also went with a JB Clutch.

Was very interesting talking to Jim.

Our specs given to him were 26/30, 600KW at all 4, street driven occasionally, built for drag, 4WD launches and abuse.

He ended up building us a kit that looks exactly like 34geeteetees pictures but with a 5700Lbs clamp cover.

The most interesting part was the discussion about flywheels.

Key point for drag was not going lighter and staying with the standard flywheel weight for good 4WD Launches.

Going from what JB had to say, there are a number of 8-9 second GTR's running the same clutch with stock flywheels.

IMHO if your going to run the stock flywheel (which should not be run on those times and power figures) or any other billet flywheel at those power levels and times you should invest in a ballistic blanket to save yourself regardless should something go wrong.

Mine is a one piece chromoly thing one pound lighter than standard with a JB 4800lb 5 puk sprung centre single plate.

Re-pucked once in 5 years though probably due for another one.

Still holds 800hp with 4 big blokes in it aye Matt? :D

      Might import a stagea

      By iamhe77 · Posted

      Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      Neil's R33 Gts-t Build

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
