Hi all. I'm interested in building a a31 for daily. I'm thinking of using a Rb25det with gearbox.

What I'm not sure about is what diff should I upgrade the rear with, and the braking system.

I'm really excited about using some r33 wheels. So ill need to convert to 5 hole

I used the R32 diff, bolts right up, hand brakes, brake lines etc were easy to work back. the only real work was on the driveshaft, one of the ends needed to be removed from the a31 shaft and replaced with the r32 end as the size was different, that was because i went from auto to manual. also when using the a31 shaft (2nd half) to switch the end with the r32, maintain the same length don't shorten it

hope this helps

what i did with my conversion is that i bought a r32 front cut and moved over everything except the shocks and spring as that set up is different to the cefiro. steering rack & lines, all AC parts front cross member, lower control arms etc. most of it fitted with very little mods if any at all. like the brake lines needed to change (just the ends) as they were sligtly different. the ac lines run a little different to the front but any they work back. like i said for the most part it is bolt for bolt but there are some exceptions but these are easy to adjust. the brakes and cluth pedals also work back. the most trouble some part of the build was to make up the brackets to hold the handbrakes and fit the r32 center consol (to work the handbrakes) also i changed the instrument pannel that 2 was trial and error cutting till it fitted. the other set of work is the geabox bracket needs to be modified. what i did was i had and extra engine bracket. the holes line up exact with the gearbox holes, so it was just a matter of cutting and welding them on to the gearbox bracket. So far its going good no issues. i have lots of pics with the build so i would try to put them up or a link to them. good luck

      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.
