Hey guys, I'm looking to instal an aftermarket boost gauge on my R34 GT-T. It's mechanical so i need to connect the hose somewhere on the turbo line. I've searched around the forums and google a fair bit and thought this sorta thing would have been covered already but i really couldn't find much, or anything with pictures, or maybe i just dont understand it.

But yeah, i thought its better to be safe than sorry, so where and what exactly do i cut and put my T piece to connect the hose for the boost gauge?

Thanks heaps

yeah, ive looked around a bit and thats what most of them say. but im not too familiar with where the intake manifold is or even where the vacuum lines are. And instead of cutting something and ruining my engine i was hoping for something a little more detailed.

like a photo would be awesome, or anything a bit more helpful.

Do some reading up on engines and their basic layout - will help you a lot in future.

See the cylindrical shaped thing on the bottom left with a black hose coming out the top of it? That is the blow off valve and the black hose is a vacuum line that runs from it to the intake manifold. You can splice your T piece into this line.

oh okay, thanks for that. I attached an image just to make sure, so the red circle is the tube i should cut to attach the T piece?

I have heard from someone that you can also cut the hose coming from that little black can shaped thing, i circled the tube coming off it. Would i be better off cutting this tube?

So which out of the two would be better to cut.

Another question is, will this cause any problems to occur such as stalling or the car running poorly? It just seems a bit daunting to be cutting a tube going to the intake manifold and attaching a little T piece onto it, thats all :)

Yes you have circled correctly. As long as it is a vacuum line going to the intake manifold, it doesn't matter which one you cut and splice into. You're cutting into a hose, but the T piece and boost gauge are blocking it up again.

As for issues, there should be none unless you create a leak somewhere. Rationalise that your worst case scenario is having to replace the hose you cut with a new one and what's the worst that could happen?

its not letting me edit my last post, but i looked at the hoses under the hood today and noticed that my T- Piece will fit best on the hose going to the boost sensor as this hose is thinner. I have circled this hose in Blue in the picture, so just making sure, is it okay to cut this hose and put the T piece there to run the boost gauge? the Blue circled one in the post i did above

No, don't T into that hose, as said you won't get vacuum.

On the back drivers side of the intake manifold there will be a vacuum line the same size as that one which goes to your standard boost gauge, T into that.

Basically you can hook your boost gauge up to anything that's plumbed in AFTER the throttle body, except the fuel reg hose, but that's at the front of the engine anyway.

thanks for that, does anyone have a photo of the location i can T into? I'm pretty confused about it at the moment and need to know how much psi my cars at lol.

It'd be the biggest help ever if someone has a photo of the hose, thanks again.

yeah, so if anyone could get a photo of which hose im supposed to put the T piece into, it'd be a great help

I've always T'd into the end of the plenum, where the stock vacuum lines goes into the stock boost sensor for the dash (this is for a R33) I am assuming the R34 is the same.

Look at the black cap on the RHS next to the vacuum line for the brake booster, use that.. or if too hard basket, just snip the BOV vacuum line.. easy.

what's wrong with the stock GT-t gauge? reads up to 1 bar.. perfect for stock turbo

Not really! Its got bugger all notches on it so it would be hard to pick what boost it is...... Useless now with 21psi BUT even before then they were pretty useless!

I will be replacing all 3 gauges sometime soon enough.

yeah i was thinking about using the hose going to the boost sensor, but everyones saying you dont get vacuum off it, only boost. I don't really get the photo of the R33 engine, im not too familiar with the hoses of my R34 yet but didn't want to send it off somewhere just to install a boost gauge.

oh and the stock boost gauge doesn't use a vacuum line im pretty sure its purely electrical.

A photo of a R34 engine bay or the hose i should T into would be awesome and save me having to take it to a mechanic over this =\

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
