R32 Gts-T Idle Problem

When i bought the car it was running a stock BOV. I then spent $200 on a Turbosmart BOV and it was great for a little while.. But now I'm having a rough idle issue.. When I'm driving and drop gears and go into neutral (or put the clutch in) the revs drop and the car stalls.. Sometimes it'll go down to 100 revs and bounce back up to a thousand but lately it's been stalling more.. Does anyone with knowledge about RB20's know what a common cause of this could be? Everything is stock except brass button clutch, splitfire coil pack and front mount.. Would putting the stock Bov back on stop this problem? Sorry for asking the question but I can't find another thread that has a direct answer. Thanks in advance.

Not wanting to be too mean to you, but there would have to be 10^4 threads on here with the exact same question and lots of us screaming at the poster to replace the factory BOV. -4 search points for you!

^^what? i can't believe how many australian guys run plumb backs they are far less prevelant over here.

perhaps clean your IACV...you can test to see if its your bov by watching the bov piston return when free reving it..

Gaz all of the AFM guys run plumbbacks to avoid OP's problem.

If it's not a recirc blow off valve then replace the factory one. You can sell the turbosmart one for sure if you're worried about the $200

umm i run afm and atmo bov and don't have that problem...it can be sorted without changing the bov.

It's also the law in oz.

Like you say it can be sorted but the reality is its not really worth mucking around with one is oz just to cop a defect for it.

Atmo BOV's cause so many more problems than they are worth on an AFM equipped car.

You can fiddle with the atmo BOV, get a retune to make it work (If you have an aftermarket ECU, otherwise factor in money to buy that) then it still wont run quite as nice as a PB BOV, then get a fine for having a venting BOV

alternatively, use stock BOV, buy aftermarket PB BOV, don't need retune, drives as stock

If your buying an ATMO BOV for the sound then you can still get that from an aftermarket plumback.

This is why I say they are not worth the trouble. You are right, they can work. But why would you bother?

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
