I really want three new guages - boost in PSI, oil temp and exhaust gas temp.

Boost and temp will be cheap Splitfires. I think I'll match it with an oil or water temp guage so there's a neat 3 guages in the central console.

The EGT however will end up being most likely an Autometer or Apex EL on the A-pillar.

Seems ok? I have doubts about the A-pillar as I don't want to be defectable.

Anything u mount on the dash/a pillar has to be lower than the highest point on your dash. Tried to mount a 5' tacho legally in my old car, didnt work, but close :(

I have EL boost on the A-pillar and Water Temp, Oil Temp and Fuel Pressure Defi's on the console. Also AVCR and RSM (mmm - Gs) are on the dash.

I look at the AVCR and water-temp most of the time. I use the speed readout on the RSM for highway driving (it flashes at 103km/h).

G's are good for passengers :)

I've never understood why people want a boost gauge. I set my boost on the dyno, and I leave it. Most boost controllers have a digital boost readout anyway.

People say "What if your boost spikes? or if you overboost to 1.5 bar? Don't you want to know about it?"

I say in reply: "You should set you boost up on a dyno and iron out all the spikes there. Has your boost controller ever "broken" and you've overboosted over what you set your boost controller at? I haven't."

Anyway. If I were to have any gauges it would be:

Water Temp

Oil Temp

in WA u can get permits for a pillar mounted gauges, aslong as they dont obstruct the vision. I had permit for Oil pressure gauge and monser tacho(albiet that was a wank permit haha). But we also have permit for the Sti with boost and oil pressure.

small gauges are fine. In words of guy at pits, cop was an idiot for point out the gauges as a defect.

"Boost and temp will be cheap Splitfires"

Don't get anything cheap - unless you just want them for the 'looks'. Otherwise you are defeating the purpose of trying to accurately monitor what's going on with your car.

As for "why have a boost gauge?" - if I, for example, blew a hose, the boost gauge would instantly tell me that. If there is a problem with the car, and it is boost related, the gauge will instantly tell me that. If my car starts to spike (for whatever reason), I can see it instantly and shut her down.

And my other 2c: buy defi

What hose could you blow that would affect boost? Intercooler plumbing? Silicon hoses on the intake plumbing? They'd all REDUCE boost, so you don't have to worry. The only thing would be the hose to your wastegate actuator.... How many people do you know who's wastegate vacuum hose has fallen off? None?

You'd notice any increased boost, or an "unlimited boost" effect from the wastegate problems before you'd look at the boost gauge anyway, true?

What other reasons are there that the boost would suddenly decide to spike? If you have a decent boost controller, I can't see it EVER changing it's settings, unless you've stuffed around with it.

The only time I can ever see a boost gauge coming in handy is when setting up the car's boost levels and gain/balance.

I think Summoner gave the truth :) Everyone loves it because it's the most active gauge. The others (water temp, oil temp, EGT, whatever) don't move anywhere near as much, and doesn't have the "COOL" factor :D

Yes, I too like boost gauges cos they move :) Everyone wants to see something working and it's actually doing something. I think boost gauges are important (to me anyway) because I have the Profec B boost controller (no boost display). I have low and high boost and sometimes I like to see what the max boost is set at. I sometimes adjust the low and high settings too, so I don't want to set it too high and blow something. I think boost gauges are useful.

"What hose could you blow that would affect boost? Intercooler plumbing? Silicon hoses on the intake plumbing? They'd all REDUCE boost, so you don't have to worry"

I'm talking about the sequential setup of a late model rx7, which is my case. Your original post didn't specify 'skylines' which is why I responded as such. On my car, the boost gauge is a neccesity - which is why 'people' sometimes need them. However, I can't imagine why having a boost gauge would be a bad thing on any turbocharged car.

The defi gauges have a memory function - so you can record the boost gauge (for around 3 minutes) and play it back. This is a great little diagnostic tool - which has plenty of uses.

You are damn lucky to get DEFI link gauges! :) They are quite pricey aren't they? Is it true that when you start up the car the gauges calibrate and the pointer on the gauges moves right through the range? Example: If you have a boost gauge from 0bar to 2bar, when you start the car the "pointer" moves from 0 bar to 2 bar and then moves back down to 0bar? Nice :D

my cefiro has a tomei boost gauge and i have hardly looked at it. Mind u at present my EBC isnt wired up properly(so it looks), so i was curious as to what boost it was running, seems to be about 0.7bar or so.. Short of that i doubt i'll actually be looking at it :)

yeah, the gauge cycles on start up, beeps, has a whizz-bang closing down 'ceremony' etc

I got them because they are made by a company that specialises in gauges - not a company that makes all sorts of shit, and does gauges on the side.

I've shopped around and they are by far the best quality on the market.

And yeah, expensive, but not as bad from within japan (cost me about 34,000 yen for the control unit, boost gauge and holder)

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
