I've just bought my first r32 skyline gtr. The car has had a new engine and the standard boost gauge and apexi boost gauge have not been connected. There's 2 vacuum lines in the engine bay one that I think is for the standard gauge which is connected to some sort of sensor on the drivers side firewall. It t's off 3 ways one way to the sensor one heading into the cabin and the other to nothing. I've had my radio and climate controls out to connect a radar detector and there is also a vacuum line behind there not connected to anything which I think is the one coming from the engine.

The vacuum line for the Apexi gauge is just sat in the engine bay not connected. It has what looks like a one way valve in line.

Any ideas where I can can connect at least one of these up?

You can tap of it from where your standard boost line. Just go supercheap auto and buy the 3 way connecter its the little plastic thingy. But if you want it like FULLy accurate, Connect it directly to the standard line or you can either go to the fuel line vacum.

The standard one isn't connected to anything. When you say the fuel line vacuum do you mean the short piece that goes on the fuel pressure regulator?

the standard one connects to a little black box on the left hand side of the firewall near the booster

i would also t-piece of that

yeah its already connected to that black box but its not connected to the engine so not picking any vacuum up. Need to know where on the engine to connect.

      App to track mods, repairs etc.

      Hey everyone, just wanted to let you know about an app I use to track the modifications, repairs, servicing etc I do to my R33 GTR. You might like to use it as well. I'm biased because my son just wrote and released it! But I think you might find it useful to... https://trackmymods.com

      Hey everyone, been on here for a while, but never introduced myself before. 1st import was a R32 GTS Type M, then R33 GTS, now R33 GTR - each one sold to help pay for the next one. Over the years my son has seen me modify and do changes to my imports and was one of the reasons for him to build an app for car enthusiasts like us. (He can only afford a 2007 Honda at the moment, but he'll get there!) Anyway, bit of a proud Dad moment as he's released an app that I use and you all might like to as well. https://trackmymods.com

      It will sound tragic and you wished you didn't have 1x exhaust per turbo. There's a reason why most S55 owners change to a single mid pipe.

      Echo the comments about the well preserved condition it's in. It has the aero bumper too for extra points. Nice car, and please keep it like that! 🙂

      1. There are no real performance benefits. It sounds different, and as the pipes are not as large diameter you can claw back some undercar clearance or run lower (if that's your thing). 2. Twin pipes, offering exactly the same cross sectional area as a single pipe** will have higher pressure drop - so will not flow as well. That's because there is more surface area of wall per cross sectional pipe area, hence more frictional losses. ** But of course, it is almost impossible to get 2 pipes that are exactly the same XS area as a given typical single pipe. eg, 2x2" is not the same as 1x 3", although it is close. If the 2x pipes add up to less XS area than the single - it will just be flat out worse. If the 2x pipes add up to a bit more than the single, then it might come out as a wash. If the 2x pipes are substantially more XS area than the single, then it will probably flow a little better. 3. No. Why would there be? What have cats got to do with boost creep?*** ***But for f**ks' sake, please run a cat. 4. If you want.
