Am after the V35 auto ratio of 3.3, which is different to all the R33 and R32 ratios

Your other options are to see if a 3.3:1 FD ratio is availabe aftermarket.

Otherwise, find a manual diff and see if someone with a slusho FM platform car wants to do a swap of the ratio. The speedo reads off the rear ABS sensor on our cars so changing the FD does not put the speedo out, and in the US its quite popular with auto owners to do a 3.5:1 (or even a 3.7:1) FD ratio swap.

Thanks for the comments, scathing.

Understand diff ratio will not affect speedo accuracy.

There is a 2006 manual Z33 diff on ebay for $250, would have bought it if it were right. The US guys quote $500 for the parts for a ratio change. Then I would have to get someone to do it (I can install the diff). Probably $1000+

Am looking at buying a low km 2005 Z33 auto diff from a wrecker, which will give me lsd (stop VDC going off all the time), just it is expensive, $800+.

Is that diff on eBay the entire pumpkin as an enclosed unit, or is it just the internals?

If its the former, you could see if someone with a slusho Z wants to just do a direct swap. Maybe offer them a VLSD fluid flush on the 3.5 FD you're giving them to sweeten the deal, which shouldn't cost a great deal extra. They drop their diff off their car and you fit it to yours, and call it quits. You wouldn't need to open anything up, which would bring down costs as you don't need new washers and seals and shit.

You could even offer to do the install for them, if they're happy to trust you with it, so it'd cost them absolutely nothing for a 3.5:1 VLSD conversion on their car.

Thanks, Nigel

Sounds very good. Send me a PM.

Thanks for the comments scathing, just thought there was too much risk mucking around with the diff on ebay. Someone else bought it in the end (mmm maybe I alerted them to it). Didn't want to get stuck with another part I don't really need. Anybody after a 6 speed box? haha

      Question about BoV on RB25DET NEO

      By MBS206 · Posted

      Something to note, on an aftermarket BOV, it's quite possible to end up with the worst of both worlds, where on light throttle, there isn't enough force to open the BOV so you get small reversion and driveability issues, and with the venting to atmosphere, it dumps a lot of fuel on shifts. Realistically, dumping to atmosphere under power isn't a major driveability issues, compared to the issues of stalling from reversion. If you're getting up the throttle, then putting the clutch in, say on a shift up, but then don't release the clutch, yes, the engine can and will stall, but, just drive around it, and that's easy, let the clutch out in the next gear and the car rolling will keep it all running / going.who wants a hard hit of throttle and then to just let the motor idle anyway?   Main issue for driveability is blipping throttle and it wanting to stall, like when parking or trying to move in slow traffic.

      As in they quoted one price, you mentioned the exhaust, and they promptly added $200 on top? Interesting.

      Note that I'm not suggesting this is a great idea. Just saying that it is something that could be done to achieve a better outcome than the more shit ideas will provide.

      What's this Foreign Object?

      By luke gtr · Posted

      I'd try removing it, connecting hoses and see if that helps. Depending on specs, it could actually be restricting the flow(it also might be helping).

      Yes, that's a hybrid BOV. The adjustable spring load ones are about making teh pressure build up higher before venting, so you get a more agressive whoosh. That is not what I meant or what you want. By "restricting", I don't mean "keep it closed until the pressure is higher, then open it fully". I mean "open it as soon as it is required, but only have a small port area, so that the flow rate out of it is slowed down". The pressure will rise to be higher than a bigger ported BOV would provide, but it would do while it is venting. The idea is to slow down the rate at which the replacement eair is flowing past the AFM, to reduce the magnitude of the air flow signal peak, to reduce the amount of fuel that is added per revolution.
