I put my new-to-me Stagea on a dyno today. I don't know the history of this car, so I thought I'd get a baseline. You know, figure out my starting point before I change a couple things up. I thought some of you may be interested, so I've attached an image of the 2nd dyno run.

Results are decent: 252.54 ft-lbs (342 nm) and 292.78 hp (218 kw) peak at the wheels and 311.29 ft-lbs (422 nm) and 359.38 hp (268 kw) peak at the crank. The car has a cat back exhaust and mushroom filters on it, but the rest is unknown. Since it's supposed to have around 280 hp stock, I'm guessing something else has been done to the car. No way a cat back and air filters gave me 80-ish hp. Time to do some poking around and figure it out.

0.8 bar is nearly 12 psi, so you have a little more boost than stock. Nowhere near enough to explain the amount of power it made at that boost, so it's going to be fair to assume that you have bigger turbos on it. -7s or -9s or something similar perhaps.

Maybe. I haven't had a chance to dig into the engine bay. It didn't come with a mod sheet, so I need to go on a fact finding mission.

Sounds like it might be a *good* fact finding mission for a change! :D 

RB26's have a restrictor in the boost line. Pop this out and it'll run 12psi all day. Maybe check this is still in place?

That's a good piece of info. I'll have some time this weekend to check it out. Don't even have to put it on a lift! 👍

Took longer than a weekend to get to it, but I finally took the time. The boost controller is in a different spot on the Stagea (between the battery and fuse box), but the hose with the yellow line was there. Sure enough, the restrictor was still in my car. Woot! 50% more boost for 20 mins and $0 USD ($0 AUD at current exchange rates 😜).

      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

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

      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.
