Yeah runs real rich you can see the AFR dropping off below 10.5 Hmmm, very interesting power, thats damn good. I would like to see the boost, when I drop into SST next I might ask steve what boost the car was making. Well, it all depends on how much power you want to make. If you think the extra 30-40hp will satisfy you then for the money spent on the safc and bleed valve you cant go wrong. If you want more power, ie: going to run a bigger turbo. I'd buy an aftermarket ecu that has some sort of boost control built in, like the powerfc or the wolf3d, rather than buy a bleeder and safc2. The best we have seen on a r33 gtst with a jap remapped ecu was mrgtst with around 285hp. Basically all he had was a HKS fmic, apexi avcr with the boost up around 12psi. Also keep in mind if you want to run a bigger turbo you will also need a fmic, if you are staying with the stock dont bother with a fmic, just back off on really hot days when you hear the engine pinging or if you do any track work.

*shrug* maybe some aftermarket cams or a HKS/aftermarket turbo perhaps. But 230hp on the same dyno I was making 245hp with an ebc set to 12psi and you only had 9psi doesnt seem right :/ must be something in there, but the car is definately running very rich and the safc2 will sort that out.

I have a cheap boost gauge and dont trust it as far as I can throw it. I turned my bleed valve up 2 turns from standard which should be 9 psi by the bleed valve manafacturers specs but the guage says around 10-12 and gets huge spikes up to 14. my next investment is a descent gauge to make sure it is the gauge as said further up, it could be the bleed vavle.

R31Heaven, why dont you just borrow one to test it with, saves you paying for another one if the results are the same!!

As with the Bleeders, i have the GFB bleed valve and have only had one problem! no spikes or anything, just once after a track day, somehow it set itself up to 16psi, and only took me one look at the boost guage to see why the car was jerking and spluttering like crazy on full boost! the stock guage didn't show me anything different to normal..

this may be since the boost guages are T pieced, but that shouldn't affect a vacuum guage!!

Most of you twats dont f*ckin read!

the stock gauge isn't crap. it's just not GRANULAR enough to read accurately!

but hey, if you rely on the stocker and blow your turbo then i'll be the first mofo to say "sucked in, i told you so"

Answer this: Have you increased the boost on your car and do you have an aftermarket guage?

There is no way I would increase the boost on my car via the factory boost guage, and anyone that is.....good luck. :D

      WGNC34 - floor mats

      By soviet_merlin · Posted

      I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.

      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.
