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.

Why cant you t into the fuel reg hose at the front. thats where mine is.

It'll work but if you ever get a leak for whatever reason it'll affect fuel pressure and therefore fuel ratios. Best to leave something so crucial alone and use one of the many other points available, the standard boost gauge nipple is in the perfect spot and is the perfect size too, why wouldn't you use it?

Ah crap time to re route some hoses.

Do the S2 R33s Have a rubber cap on the front intake manifold nipple from factory?

ok, so im 99% sure this is right now lol.

I take the line i've outlined in red out of the sensor (circled in blue). Hook the T up to that, another tube back to the sensor and then the vac line from the gauge to the other end of the T.

Correct me if i'm wrong.

I dont blame this guy lol, i knew almost nothing about the engine lay out also, and the information given here was helpful but i was a bit reluctant to T into the BOV line.

My boost gauge is still sitting in my glove box, haven't had the balls to cut anything and connect it yet either.

But just to confirm, is whats said in this post and the photo above correct? if i follow this, would the boost gauge work with no troubles from the car 100%?

so, i bought a cheapo gauge from ebay last week.

how would i be able to tell if it's going to be more accurate than the stock gauge or not? Also has the same style mount you just linked Johnny :)

Speaking of good gauges and accuracy. Does anyone know what the quality of TurboTech's boost gauges are like?

I recently ordered a boost controller from TurboTech (after reading how awesome they were) and it came with a mechanical boost gauge.

Haven't hooked it up yet tho, wanted to know if it's even worth installing first.

Now I assume that they are not their own TurboTech branded boost gauges, that they merely on-sell another brands product packaged in with their own.

I also assume that with all the raving reviews of TurboTech's controllers they wouldn't go jeopardising their great reputation by supplying sub-par accessories; but hey, I might be wrong...

I'm going to assume they're pretty accurate Brad. Like you said, they wouldn't jeopardise their product with something that won't show an accurate (or more accurate than stock) reading.

This might be a very stupid question, but I'm going to ask anyway lol.

I've read around that people test the accuracy of their gauge by using an air compressor.

I don't have an air compressor, but would I be able to use one of those free air hoses at petrol stations to test my gauge?

    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
