Hi guys.
Id like to run a the triple gauge cluster as fitted to GTR/260RS etc in my GTS-t for the purpose of having a voltage and oil temp guage without having to run aftermarket items.
Was this an option on the GTS-t, or is it prewired at all?
If not, am i able to wire it in? Id assume the voltage guage would be quite simple. Will there be a fitting somewhere on the RB20DET to run the RB26DET oil temp sender, or will the RB20DET have a sender already, just not wired to a gauge?
For the boost gauge, would i be able to just wire it in parallel from the sensor mounted to the firewall that sends signal to the dash cluster? I know a second boost gauge is redundant but id rather have it working than sitting there with a non-moving needle.

Thanks in advance.

No, not an option on GTSt. Therefore no wiring in place for it. Also no oil temperature sender. To fit an oil temp sender you'd need to put a sandwich plate on the engine and fit the GTR's oil temp sender in that.

Volt meters are the single most useless gauge you can fit to a car. It's not the 1970s any more. You already have a boost gauge on the dash. Therefore 2/3 of the GTR 3 guage set is worthless. Therefore fitting one to a GTSt is pretty much worthless.

You'd be far better off getting a single-DIN mounting panel and 3 of the ChinaBay stepper motor guages (or proper Defi ones if you're flush for cash) that will actually do something useful for you. I did exactly this. Oil temperature - big check. Probably the single most important gauge you can fit to car that you thrash (other than a decent oil pressure gauge). Boost - wanted to make sure I had something more reliable than the stocker, which are known to tell fibs and also don't go high enough anyway. And I got an EGT guage. Very useful tuning aid, and also serves as a warning for leanouts. I got the ChinaBay guages that have peak recall and change colour to RED lighting when they alarm (go over the max setting). Cute.

Your desires may differ. I was torn between what I chose to get and the other option of losing one of those choices in favour of an oil pressure gauge. At the time my dash's oil pressure gauge was workign perfectly but since then it has started flaking out. If I were doing it again I might not fit the EGT and get the pressure gauge.

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
