The crank pulley of the rb25 is thinner as is the power steering pulley on an rb25 as the power steering pulley only has 3 ridges on the belt instead of 4 like with rb20 as the rb20 has a big pig of a p/s pump due to the hydraulic hicas.

I am running an rb25 with rb20 accessories atm. everything lines up, it's just a matter of replacing the belt for the P/s.

If you can check that the p/s shaft of an rb20 pump is the same as an rb25 pump you could run the aftermarket rb25 setup.

im most probably going to be putting an rb25 PS pump in as my current one is a hicas RB20 pump but it has a bolt blocking the secondary hicas line... very dodge - upsets flow characteristics of the pump obviously

i just wanna order some lightweight pulleys - wonderin whats gonna fit

      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.
