This is for an R33, and is the way i done it for me and a few mates, if ya got a different car to the on ein ya avatar let me kno, i've done a fair few gauges now. ;)

Step 1: Locate vaccum line on back of intake manifold which if you follow is the only vaccum line goin off that part to in front of the driver in the top left corner of the engine bay where it goes into a small black unit which is the factory boost gauge unit.

Step 2: Cut this line half way and fit a t-piece into it.

Step 3: Fit extra vaccum line onto the t-piece and run it through the firewall hole near the factory bost gauge unit and down to near the drivers pedals (you'll have to really get under the steering wheel and shove ya hand up there and move the carpet to the side to do so. Once you find the line run it to where you want. (Don't use the nylon vaccum line supplied, only use it to connect the the black rubber vaccum line to the boost gauge at the gold fitting behind the gauge. Only about 6cm or so of the white stuff then throw the rest, it bends to easy and restricts the reading of the boost gauge as it comes all wound up with the gauge and is impossible to straighten without it bending anywhere.

Step 4: Fit the gauge cup to where you want the gauge to be positioned.

Step 5: With the wire coming off the back of the boost gauge, run the black to a solid ground, and run the red to the positive wire coming off the back of your cigarette lighter. This way when you turn on your lights at night, the gauge will light up also.

Step 6: Hide all the wiring and use convoluted tubing to hide boost gauge line and wires to make it neat and hidden. Fit gauge to cup and start boostn :(;)

I second that!

Just tryin to feed it through to under the steering wheel area and getting nowhere. I am feeding it through a hole just a little bottom left of where the throttle cable exits the firewall. Is this the correct hole? where is it suppose to come out? Or do I drill a hole lol.

Lol, Blast from the past dude but,

Yeah use one of the existing firewall holes, usually they have a rubber grommet you can run your line through, DONT DRILL HOLES !

You dont have to cut this....

Your gauge should come with

T-piece

Little hose for t-piece

vac line

gauge

So pull the line off, put in your t-piece. Put the line for the t-piece on and put it back in the same spot you pulled the vac line out off. connect vac line to other bit of t-piece then to your gauge. done

if it helps, there is a hole on the bottom right drivers side footwell (you'll have to pull back the kick panel) from this hole it feeds perfectly to were the factory boost sensor is (the little black box on the left side of engine behind the strut tower)

Sorry for my ignorance but what do you mean by kick panel? Is that the plastic cover just to the right of the throttle pedal that seems to cover a whole lot of wires on the side?

cheers

yep thats what i was referring to. there should be a screw at the back next to accelerator and 2-3 clips next to the driver side door - after you've undone the screw, a little bit of force and the panel should just pop out (be careful though).

you should see a fair few wires etc, gently push them to one side and look upwards towards the right - there should be a hole there. Obviously best to do it in the day light. If you cant see it, pop your bonnet - look at left strut tower - behind that there should be a black box (factory boost sensor) below that is where the hole should be (from memory)

ill take a pic if you want.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
