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?

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

Yeah was planned, cheers.

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.

Do them as you'll find when you remove them they are perished/dried. Its probably one of the best things to do as makes the car so much more responsive. Do ball joints while there too.

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.

Yep he is an awesome bloke, we work together on that car. You will have fun at the 6hr, Tony doesn't stuff around when he goes racing does pretty well.

Also did some work to the shed and a massive clean out of stuff. It's now got a small fab/dirty room and has helped keep shed cleaner. Built some new work benches and re organised things also got a TV out there so good having something playing while working on the cars. Got a pedestal drill and linisher off a mate that need to pick up too.

A bit from column A, B and C. Mainly C Update time, after deciding it was time to tick off a bucket list goal I finished up full time at MSR and have gotten back behind the wheel and making progress on the S15. Goal has been to drive Bathurst at an event and I have had my entry accepted for Challenge Bathurst in November. Since I don't want to go unprepared I need it running to test and get comfortable. Been chipping away at it and started by stripping inside, getting it all cleaned and sealing some holes up. With stripping inside I removed the whole wiring loom and found a few surprises.......... its pretty butchered and shit branching and I'm not a fan of the haltech fuse boxes so it's all out and trying to come up with a plan to rewire it all either new fuse/relay box or pdm. I haven't been happy with how I did the intercooler mounting and been wanting to tuck it up under rad support. O e issue with that is headlights will need a decent trim or get replacement covers. Took the time to mount it with some stand off's and new hardware. Stands are some m8 button bolts, washer, aluminium tube and factory radiator top mount rubbers. It's nice and solid also stiffens rad support which still requires some trimming. Bonus of factory rad mounting is used all factory hoses just need to weld a pressure cap to radiator now. Got sensor block and fuel filter mounted. Plan today is to get vac lines all sorted with push in nylon tube and design oil cooler mounting solution. Been driving BRZ a heap and went out to Morgan Park for time attack and went pretty well for a wet day. https://youtu.be/gAlQgcQpWj4?si=kojOAOjhhX_X3AXR Getting pretty comfortable in it now and want to do a few more bits to it but restraining myself as don't need 2 race cars at the moment.

Good you making progress with this rig. Aluminium welding is painful to learn, have you got a pedal as I found it so much easier with one. If that's the AMG I think it is, you would working with Benny?

Solid update, got all the downforces now. You going to be running aus time attack again? love the jacking solution, spend the dollars on what makes it go fast is best way.

Welcome, the rb in S chassis is favourite of mine. Lots of info here and a few ways to do the swap back in the day. Post up some pics or start a build thread here https://www.sau.com.au/forums/forum/190-members-cars-project-overhauls-restorations/

yes easily doable was very common conversion around 15+ years ago Require: Sr20 cross member and engine mounts sr20 gearbox or bell housing if manual CA already sr20 loom and ecu sr20 radiator (or make a cross over pipe to us CA style radiator) sr20 engine All parts can be sourced from an s13 Will require some mods to engine loom to body loom plugs but plenty of info out there on that.

Cool piece and gone to someone who will use. Can close/delete thread

Where ever the fuel reg gets it reference is what I use to T into for map reference been a very long time so where it goes to plenum/runners I have no idea but never had issues.

What ecu? Same shop every time? Same ambient temperature? If timing is correct then pull plugs and see if lean or rich. Dyno can also read different if they have changed ramp rate or not set tacho/speed properly

Selling hks rb25 cast manifold and waste gate. Never going to use as don't have Rb powered car Unknown condition of waste gate diaphragm $900 Pick up only Ipswich Qld

A mate had this style seat from SAAS years ago and they were pretty comfy but the quality was not great especially after a few years. Have you looked some 86/BRZ seats? the seat warmer is great and I use it a lot. I just drove almost 2hours and no issues with comfort.
