ok so to tell the story ill start from the begining.

I bought my 98 40th aniverseary r33 gts-t about 10 months after my stock 96 r33 was a write off after the big perth hail storm.:(

I got it with about 70 000 on the clock and it just seamed to have much more power. So not being the bees knees on cars and all and just getting to learning about everything you can do with mods i just left it as being a better car. Anyway today i read a froum on how to ground the standard solenoid and run at 7-8 psi so thought great sounds easy so went to do it. Well i looked at the soleniod and it had no hoses going into it (wtf) so had a look around. Then i saw that to my supprise i had a blitz sbc dual soleniod cool i thought. Anway traced the cables into the interior and they went all the way to behind the ash tray, so i pulled it out and there was the boost controler there all the time ( felt like bit f a bumb ass) . So now i had to have a bit of a play and got some good boost out of it but as i'm still kinda knew to the whole mod thing can anyone give me any advise on what it should be set at with a stock turbo as don't want to over boost the engine but really stoked with the find.

10psi should be safe, hehe dunno why the previous post didnt load up when I viewed the page before, I wouldnt go more than 12psi though.

in saying that I had an rb20 180 before and ran that around on 1 bar with standard turbo, ca18 side mount (thin as fk) 3" exaust and a walbro pump for a year or so and didnt have an issue, could be that I got lucky though, next guy to own it wrote it off though so I cant say how long it lasted

If it goes better than your old r33, then i would just see what boost it is running before you do anything. At a guessyou will get better gains by having the ecu remapped than than turning the boost up more.

How do you know it only has the standard turbo? Could be a hi-flow. Could have an after market ECU. Does it have a standard exhaust, intercooler etc?

Time to do some poking around in the engine bay perhaps. Might find some more hidden treasure. :(

yeah thought that too. It's got 3 1/2 inch exhaust blitz nur spec, standard intercooler though ( Got to get an after market one next thing i'm doing anyone got ideas on brand? ), jap psr and psr-k stickers when open the fuel flap to fill up (not sure what this means, Bigger pump or bigger injectors) , hks super direct flow pod. Don't know about ecu how can you tell if it has after market one can any one tell me? got a conect cable on the way will that tell me when i plug it into my laptop?

Might just have to go to some where like hypertune and get them to have a look.

oh yeah the boost controller plugs into a little box called greedy turbo data link not sure what is but think it for my boost gauge. Any ideas would be awesome!

i havnt read the whole thread, but personaly i would run 8-10 psi, because if you have the standard ecu, it will be to R&R with anymore psi, and it will feel like shit and not smooth

      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

      Ethanol Content Sensor - Always at 11%?

      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.
