My stagea which I've owned for about 48 hours is doing my head in! Bought it and drove home ( 80miles ) half a mile away from my home the car misfired and cut out. Would only start when cold. I've changed the afm and it now starts all the time but when it warms up its smokes ( black ) no power, and when you put your foot down and the boost reaches 0psi the fuel cuts out completely until you release the throttle. Changed afm and O2 sensor. Still no luck. Don't wanna have to get rid if the car already but I can't keep throwing money at it and I haven't even driven it properly yet! Please help!

^^^ Yep I had that problem once. If you disconnect the sensor the ecu has a default map that will keep you running til you get a new one.

You don't say where you are.

Don't keep throwing money at it - find a mechanic/workshop familiar with RBs and get them to have a look before you buy stuff on spec.

This is why you diagnose an issue before buying parts.

An intake pressure test is the first thing I would have done...

      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.
