I thought they were a consumable ?

IE one or two race working life.

Get's expensive with magnesium alloys :blush:

Pockets ain't empty cus ?

LOL! No...Still got some left

I was hoping if they are made to order I could just get them forged in a standard wheel Alloy as apposed to Mag-Alloy.

I know they are centre lock, But I'm about to fit a set of V8 Supercar brakes and will get the hubs made to suit.

I just like the look of the old Group A cars...

Wheels were made by Cast Alloy in Adelaide(90% sure)......be aware that there are 2 different wheel setups....the 1990 wheels were setup for smaller hubs and lighter......1992 wheels have a larger hub setup and were heavier. You can tell the different wheels fairly easy as I am pretty sure the smaller centre lock's had the Nissan logo on them.

I do have access to some genuine set's of wheels, but all of these wheels would have to be crack tested and the price is a little heafty for what they are.....IMO the guy's dreaming if he thinks his going to get what his asking!

PM me for further detail if your interested!

talking about a race car or road car here??

If its a race car and pretty serious I have a set of Front and rear uprights that I have designed and machined for an R32 GTR to use center locks.

Revised geometry, uses 997 cup car bearings, and drive pin PCD (997 cup wheels bolt straight on) Custom upright, hub, Currently has radial mounts for Alcon's and everything needed machined from 4340 and heat treated. I could re machine the hubs and drive pins to suit a different wheel.

Only have 2 new nuts though. Plenty of 2nd hand ones but wouldnt be using them.

Made them up for a customer who now ownes them but is about to abandon the project and buy an R35.

They havent been circuit tested ( not worried about strength only the geometry and steering changes) but in simulations they are good.

If your not jerking around and seriously after something let me know.

Thanks for the replys guys, It looks to be a bit of a dead end as I won't even be able to get the car cert'ed with a centre lock wheel. The car is half circuit, half street car so it would still have to be legal for the road.

Just as a matter of interest Risking, What would the uprights etc go for? There is a race GTR over here that wants to run ex-V8 super car wheels, The uprights might be right up his alley.

      RB25DE NEO with Haltech ECU

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
