Hi guys, a few things i'm unsure about...

1. Should there be something attached to the end of this valve?

2. Where abouts do I find the engine number, have scoured all over the engine bay but cant find it on any plates?

3. Dump pipes? I think my R33 has a 3" dump pipe that the previous owner didnt know about. What's the diameter of stock pipes? My 3" pipe comes off the back of turbo and connects to Cat Converter? Yes/No?

The intake plenum can indeed be spotted in that pic. It's the large piece of cast alloy on the left of the pic. If you look at your strut brace and go about ¼ of the way along from the left, that's it under there (the closest bit of the motor to the driver's side strut tower), with the throttle cable running above it.

The connection you have circled in your first pic is the line from your plenum to the stock BOV, but seeing as you're running a Turbosmart one, you could just as easily pull the stocker off and put a blanking plate over the holes, because it isn't doing anything.

Yes...it can be spotted in your excellent photo.

The open valve you are asking about is on the end of the Blowoff valve. The blowoff valve or BOV is mounted on the air intake pipe from the intercooler. The intake pipe is joined by the large rubber tube to the throttle body. The throttlebody is bolted to the side of the intake plenum.... the large alluminium thing underneith the strut brace.

If you lean over the engine bay from the drivers side and look directly down over the accelerator cable at the side of the plenum facing your BOV about 1 1/2 ins to the rear of the cable and low down on the side of the plenum there should be a similar valve....in your case it should be blocked off. This should be joined by vacuum tubing to the valve on your BOV.after unblocking it

The number you need is the VIN no. This should be on the Manufacturers plate on the firewall Not the compliance plate which is usually on the inner guard

Edit Ha.... Turbosmart is writ rather large isn't it !!!

sugest you get together with someone who knows Skylines and have a good look around your car to see whats what

      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.
