Is something missing?...

[Anquetil]

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?

isnt that the line to the bov? that should goto the plenum somewhere

[Nismo_R33]

Anyone can provide a picture for a stock BOV with all the hose attached on it? I want to know where do hoses from a stock BOV connect to. I want to put back a stock BOV and see how's my car go...

Thanks!

It should have a rubber tube on it leading to a similar size "valve" towadds the rear of the intake plenum

Where abouts do I look for the intake plenum?, can it be spotted in the attached pic?...

edit: oops shit i didnt realise you had another BOV, dont worry about the line they have probably blanked off your BOV

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

Always a wealth of knowledge, thanks guys.

I'll have to corner some of you guys at cruise or something so you can give me a short lesson on whats what?
