Hey guys,

Out of curiosity how much power did you put out before your gearbox has blown with the rb30.

Give us a rough breakdown on the
- clutch ( single / twin / triple plate )

- torque figure

- kw / hp

- how you drive it ( track it here and there / often or street it only )

My gearbox is in great condition when i was running 234kw on the 26 and redline oil but now ive got a RB30 with HKS2530's expecting close to 600hp, probably a decent torque level too with the ported head, ported manifolds , ported rear housings etc...

Going to wakefield soon.. Will probably blow the gearbox there... hopefully not till the end of the day haha.... can only hope !
I've got a single plate 6 button brass button now without a spun centre which is gna be a bastard... Lol... told jim berry i wanted something nice and driveable but he gave me that ... oh well..

How did yours go ?

Also interested in this. I am building a 26/30 at the moment and will be ordering a twin plate from Direct Clutches Australia. Expecting to push a high torque figure so I'm going to have to be quite gentle on the box.

Guys, what's your turbo selection?

Precision 7175, come on Paul give me the bad news. :)

On the other hand, give me directions for a good box that should hold up......

Good luck :D.

As for the box, you'll start to realise there is a "gap" in the market. OS set, maybe, but a few guys on here have busted them with sub 500 kw atw, let alone the 5 million you're gonna make with that thing! Whatever the direction, it's $$$ and lots of it! The 1-4 PPG helical dog set is prob the cheapest way out.

Ive been lurking in that PPG thread of yours a few times now, seems to be the right way going by discussions.

At the moment saving pennies and dimes, and trying to convince my son to do the change before the engine goes in, while he still has a box to work on before he blows it.

Watching.

I have an rb30det in a patrol, same gearbox (internally), weighs in at 2200kg on 35" tires, so has massive drive train load. (and 240,000km old)

My only upgrade was the cusion button sprung center clutch- 2100kg pressure plate.

Don't have a power figures yet, but guesstimate around 200-210kw atw?

      Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.

      What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.

      Misfire/stalling issues

      By joshuaho96 · Posted

      Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.
