hey guys im redoing some bodge wiring someone has done on my Rb20 s13, and discovered that 1 of the 3 02 sensors wires is not hooked up, it goes to the RB20's dash plug ( brown wire ) I have looked at alot of wiring guides for this conversion, but not one thing is mentioned about hooking up this wire, I think it goes to 12v ignition, can anyone confirm?

also, that F&*king silver rectangle box resistor looking thing, can't get a simple answer from any site as to what it actually does, injector resistor? both of its wires lead to a dash plug on the rb's loom, but still no guide says anything about wiring it up

same goes for the lower idle control valve, not wired up either

thanks for any help in advance, Rich

The aux air valve under the plenum is electrically heated. The wiring is just that, to power the heater. The valve is open when cold. Closes up as it warms up. It should be wired up per the RB20 wiring diagram.

The RB20 wiring diagram is freely available in the R32 GTR service manual that is all over the internet. It shows you all that you need to know.

      Yep that's pretty much what I want to see. Racecars that look and sound like the Group A but with newer tech underneath to make them faster and safer. I'm sure there's enough VK-to-VN commodore, E30 BMWs and Foxbody mustangs shells around to make up a decent number of cars with hopefully a couple of sierras, rx7 and R31s in there too.

      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.

      Wish someone would start a racing series for Group A replica cars, a bit like Touring Car Masters but for 1985 onwards and not grandpa's falcon and/or Monaro. I know they race in some historic class but that's for original cars, no replicas allowed.
