Lines for Boost / Oil gauge????

[Edub1]

Which vacuum line is the best for splicing in the line for my boost gauge?

Also, my oil pressure gauge seems to hook up the same way, where does this go?

For boost I used FPR vacuum line on passenger side of the intake manifold. Some boost gauges come with the small T thats perfect for it. Depending on which oil pressure gauge you have get a 1/8 bspt (someone correct me if im wrong) adapter to whatever size the sending unit is threaded for. Then take out the factory Oil Pressure unit and plug in your aftermarket one. The factory oil pressure unit is right below the oil filter. Disconnect the factory one or just leave it there up to you.

Yup, Nissan uses 1/8 BSPT while most gauges I've seen (Autometer, for instance) uses 1/8 NPT.

SPL has an oil filter sandwich adapter that gives you two (I think) BSPT ports so you can run oil pressure and temp without some weird configuration of T's and adapters.

It's an Autometer gauge. So I have to buy what, something to convert from NPT to BSPT?

Yes sir.Boost tap into fpr line. Oil gauge goes to where your oil sending unit is...or being you got a feed for your turbo thne you get a T one goes to turbo while other is for your gauge....

All my oil pressure gauge has is a nylon hose and a rubber adapter for a vacuum line. No threaded fitting of any kind.

Is it mechanical gauges? Sounds like it. Try to get a electric one, to me its way easier to mount and pass lines threw the firewall.

umm how about that bolt on the top of the collector? cant that be used for a boost gauge, or?????? cuz thats what I used for a faze boost gauge with a threaded fitting, and it works well.
