I've seen it suggested that it's x100 mm Hg, ie 700mm Hg, which is slightly less than 1 bar (760 = 1 bar)

I think that's what on the cluster anywayz.

Makes sense..

I knew it was something like that.

the gauge is quoted in millimeters of heilium. This is a very old measurement which is pretty much obsolete. A stock HCR32 runs 10PSI of boost, this is what the actuator is set to, and what is displayed when you hook up an aftermarket boost gauge.

No, it's millimeters of MERCURY, 700mm of helium wouldn't be much pressure :D

It comes from when pressure was measured by seeing how much mercury it moved in a measured glass tube. It is also called a 'torr' 1 torr = 1 mm Hg.

either way you cut it the stock gauge is usualy wrong 1/2 the time anyways so just get a good aftermarket (not autometer) boost gauge and call it a day.

What's wrong with autometer? Autometer have been around for decades in the US and are made in the US.

I think you mean autogauge?

no i meant what i said, auto meter gauges are not as accurate as they tout.

my buddy with a rx7 had a auto meter gauge that said he was only boosting 7-8psi he threw on a greddy gauge (electric) and it showed boost to be more like 12.

just recently a buddy of mine dynoded his s13 hatch with a rb20 in it and the auto meter gauge read 11psi when it was really boosting 15.

from what ive been told the stock boost on a BONE stock gts-t is 7psi, however when the std exhaust has been dropped in favour of a highflowing one boost jumps up to 10psi.

From what you have been told is correct (sought of).

A stock R33GTST runs 7psi - RB25DET.

A stock R32GTST runs 10 psi - RB20DET.

RB20's and RB25's use different turbos, the RB25 (R33) turbo is slightly bigger than an RB20 (R32) turbo - therfore it can make more power at a lower boost level.

My R32 was running 10 PSI on my aftermarket Greddy Guage. After putting in a 3 inch turbo back egzorst it used to spike to 13psi and sit at 12psi all day - this is because the bigger egzorat is more free flowing and can get rid of gasses quicker - im sure on the exact technical term for it but thats what happens when you do egzorst mods to your car i.e: Air filter and egzorst.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      R32 GTS (RB20DE) Injectors Replacement

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
