Everyone I know with a90 supra at time attack aren't having issues with 3-5 fast laps so far and one is decent powered one too. Saw a k24 swapped 86 with a 8hp70 and big slicks and aero which had no drama's at QR and Manton Park. I've stuck a 25 row cooler in my setup with 8hp45/50 in the hopes of keeping the oil cool as I plan on some racing next year that 20-30min sessions. I've also geared my car so won't be using 7th and 8th gear too. @Dose Pipe Sutututu just needs to get that samsonas in already and have that tassie guy fit a head and rev it too 11ty thousand rpm.

Congrats mate, great result. Mega lap, can't wait to see how you go at WTAC.

GTX2867R GEN 2 NO OUTPUT FOR BOOST SOLENOID

Drill and tap housing or weld a bung on hot pipe. -
Does the stagea have the gearbox control in ecu or separate controller? A mate did this conversion and went a r34gtt ecu with Nistune and added a few resistors and diodes to ecu loom to give ecu a few fake signals and gearbox uses factory controller. Old R34 +T thread That setup has worked well but is all being removed for a Link plugin and 8hp50 conversion soon

Hope it finds a good home and is well looked after and appreciated, be a great car for Morgan Park sprint series and the odd hill climb.

Back on topic for you for a post Will it be on pump or ethanol? 2025 Spec RB build: G30 660 .83 would be good artec manifold turbosmart 45mm external gate 1000cc Injectors Kelford cams 264 and springs Pistons and rods for insurance Oil pump with billet gears Headdrain and all good oil mods Quality intercooler 3.5 inch dump pipe to decent exhaust Link plugin Ecu or what ever your tuning is comforatble with Bolt on Trigger Kit - Nzwiring kit is go to ARP Headstuds Quality headgasket quality fuel pump- a TI/walbro 525lph PWM would be the go Quality fuel reg Will be over $15K AUD Enjoy the noise of rb on gate at over 7400rpm. Start looking for gearbox conversions if your hard on the gear. Now I've been there and done that with rb powered street car (2007-2022) much prefer newer stuff. Anything 90's Japanese is not a great experience these days and highly over rated. My 2015 Brz with a heap of suspension mods is such a better car even with out the power of my old s chassis' even on track. If wanting to play light chassis and decent power for a giggle a k swap 86/brz would be the go Check my old build for engine stuff I really need to pay attention to post 2016 BMW stuff but seem all very heavy 1600+kg

Great work Duncan, any events local you will give it a test once all done?

Rob's S Chassis track cars. Now with more s15 and less 180sx

Sweet, yeah hoping stock gears will hold up. May use the transbrake feature on hill climb starts so that will test it. -

So left off with high hopes of having a gearbox in pretty quickly........ Got the adapter plate that week and had to chase a few threads and work out how/where everything goes as no instructions. Got the adapter fitted, test fitted gearbox and found had to cut and shave a few things. Tunnel required some hits with a decent hammer to give some clearance on passenger side but it fits with no problems, could fit a 8hp70 with a little more work. For a cross member I wasn't going to spend $1100 on so shiny machined piece. Went through a few designs and remembered I had a gktech s chassis to cd00# cross member. Fitted that and found its close enough with a few extra bits welded so have gone that way and still a work in progress. After this got into modifying the intercooler with some bends and clamps. I was procrastinating on this as was not keen to cut up and weld it myself but happy with the outcome. Onto the radiator shroud and oil cooler mount. This thing took way longer than I thought it would but having to add an extra oil cooler for the trans and wanting everything within the chassis rails its good enough for now. It mounts to the chassis and gives plenty of room for lines and pipes. All the coolers are rubber mounted and sealed the shroud on the top and sides, will use some tape to seal the bottom gap of about 10mm. 20250508_111500.mp4 Next job was to build the new diff and after a delay with a friend got built this week. I ended up putting it all together with supervision and was good to learn how to set one up correctly. I ended up going a 3.69 ratio, nismo 1.5 way gt pro with gtr Axel's. Stripped it all down, gave all the parts a good clean, pressed on new bearings and set backlash. Was good working in a clean assembly room with all the gear. Once got home wire wheeled the case and hit it with some rollbar/chassis black paint. Got a few more bits done but will leave them for the next update. -
Contact Jessestreeter.com/Skevas Racing/JustJap for a new r34 rb gearbox or go a cd00# conversion. No point playing with unknown condition gearboxes.

Such a shame places like Amaroo Park have been redeveloped, smaller tracks always make for good racing. Cheers for sharing @PranK there's some good Lakeside video's too. Its so hard with older the cars as parts are so rare and everything was made for a particular chassis at that point in time. Even the V8 Supercar Blueprint era cars are all different between each chassis within a team as they learnt things and made improvements. The COTF cars between each Chassis builder is different too especially motor/oil systems/intakes. The Group A stuff is worth so much too especially chassis with good history. The only way to do it would be composite panels and similar engine drivelines to the original cars. Ford sierra running Focus RS driveline, Commodore running a short stroke LS/LT or a Falcon with coyote and a H Pattern dog box. Could use a standard ecu across all models with a Torque Map and DBW for parity which is not even used in Supercars currently. Hell a TCM is almost a full chassis car these days and the suspension is not even close to standard style in the front running cars.

A little more work this week. Fitted astra power steering pump in the boot with a lowe fabrication bracket. Gave the pump a good clean, fitted Anderson plug and high pressure fitting. With the intercooler being flipped under rad support factory headlights weren't going to work. Ordered a set of origin battle lights, they arrived so got them test fitted. Will require some fiddling to fit nice but was an easy quick option for now. And today we pulled out the manual Rb gearbox and test fitted a ZF 8HP50. It will fit with some casting tabs cut off and small tap of the tunnel with a hammer. Pick up the adapter plate Wednesday so hopefully all bolted in Friday and measure for tailshaft which will be a 2 piece. Been doing a lot of ecu, pdm and tcu loom design so when comes to wiring it in a few weeks will all go smoothly.
