Factory hot rods from all the front runners. RX7 SP and the M3R both developed by Australian engineers. No doubting the all round ability of the 911 RSCS either, lacking the straight line snot of the Supra but much better braking.

The R33 V spec really wasn't in the hunt, other than making a blinder of standing start.

From memory the Horsley-run RX7 had cooling issues in the 12 hour events and they learned that reduced rpm and less power was needed to make them live.

Who wouldn't want to run in an event like this one?

The front running machines in this event were hot-rodded "production" cars with generally a lot of sensible freedoms for racing. The "showroom" tag is definitely misleading, but the category attracted good interest and a range of driving talent into diverse machinery. Inclusion of high spec exotic sports cars saw significant speed differences 100km/h +, with inherent safety concerns.

This event showed some damn good tactical racing and highlights the driving skill (and lack of awareness in the closing laps) out there in categories other than our current staple of taxis.

Can't seem to post links anymore, but found this regarding the M3R:

Frank Gardner developed, 15 built, 11 sold to "approved" public buyers. AP Racing twin plate clutch, 4 piston brakes, special shocks and springs, light driveshaft, special diff, Schnitzer cams, cold air snorkel, dual oil pickups in the sump, oil restrictors to the head, deleted A/C, dummy lightweight rear seat, front splitter, Gurney flaps on spoiler, special lightweight BBS wheels. And you needed to have a CAMS license to buy one.

RX7SP

Allan Horsley developed, 35 built. Carbon fibre nose cone, special aero front and rear for cooling and reduced lift, 120 litre fuel tank, intercooler and exhaust mods, light weight seats and carbon bits, 100kg lighter than stock, special wheels and brakes. Porsche beaters, but proved fragile if run flat out. Difficult to keep cool.

Evo 5 RS - thinner panels, thinner glass, deleted A/C, quick steering rack, close ratio gearset, mechanical diffs. Rally spec brakes/wheels (smaller diameter).

Over the years of this category running there seemed to be constant manoeuvring to have special bits or limited edition models allowed to compete.

Wiki search of Australian GTP gives more info.

      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.
