Standard Geabox Gear Sets And Flywheel Questions

[The Mafia]

Hey Everyone I have a RB25\30 built, with a GT3037 turbo. I tune cars.

I have a few question about my drivetrain.

Gearbox:

It looks like the hardening coating is coming off my Drive gear (4th) and 2nd gear. I have been advised to replace them or it will shit itself down the track. has anyone ever bought anything that is not genuine nissan?

I have no idea where to start or who to talk to.

I wouldn't mind looking at aftermarket options, and maybe some tougher gears in the early cogs, maybe first and 2nd, IF they can be had at a resonable price. Otherwise I'll just put fresh standards in.

Flywheel:

My Cast iron flywheel has a nice blue ring in the center due to heat. I have been advised to change it. Does anyone know any suppliers that have aftermarket ones at a decent price? I'm looking for something steel that is safer.

Should I lighten it also? I've been told on the RB30 it won't suffer the same cons as bad as a RB25 or RB20 (Having less torque up hills etc).

Can anyone share their experiences?

This is the part I need.

Has anyone ever sourced one from somewhere before?

ur better off just gettin a 2nd hand box cuz to pull the gearbox down to replace the cluster shaft is alot of effort. and thye cluster shaft from wat ive been told is sumwhere round the 1200 mark from nissan. if u wanna do it up u could get a os giken gear set etc ive got a thread going for par gearsets to see wat ppl have to say about them.

Only nissan would sell that layshaft by itself, otherwise all other (aftermarket) manufacturers would have it coupled with new gears with different tooth profiles.

Flywheel, if you get a steel one for strength then don't lighten it as you will weaken it, the jap clutch kits that come with flywheels are not steel but are excellent from what I've seen.

Nissan quoted me $590 for that whole shaft.

Thanks for your replies. Appreciated. Apparently there is aftermarket alternatives out there too.
