Hey guys,

Can you guys out there help me out with something pls?

I just had my rb26 rebuilt and just got my car back on the road today and i noticed something strange. When i am loading the engine, or when it starts to hit a bit of boost, I can hear a sound which sounds kind of like an air leak from the left side of the engine bay kinda like "chu chu chu". When I get off the power it sounds like I have a blow off valve on the left side of the engine bat. Also it feels a little bit hesitant when it makes that noise. Another thing is when it is idling it revs around 1.1-1.5k, which is a bit higher than normal.

Does this mean I am having a leak some where in my intercooler piping?? Or some other hoses?? Does anyone have any ideas on what I should have a look at?

Current mods: Air filters, exhaust from front pipe back, BOV, forgies, new bearings, oil pump etc etc

Thanks in advance

Cheers

Phil

sounds like compressor surge.

did you change turbos as well?

try loosening the spring tension on the BOV to full soft and see if it changes.

yeah the turbos has been changed they are R34 n1s. but they have been changed b4 the engine was rebuilt. Ok i will give that a try thanks for the help buddy. Will let u know what happens.

Cheers

Phil

      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.
