Please can anyone help? I own a 97 Skyline GTR that is running on 5 cylinders most of the time. I have taken the car to Nissan and they have replaced the plugs and number two cylinder coil pack, and the problem is still there. Nissan can’t find the problem and they can’t find anyone that will look at the car either. I think it has something to do with the electronics but not sure. It runs like crap nearly all the time now, but if I put it under a little boost while its cold it runs normal till it warms up then runs crap again. If anyone has any ideas on how to help it would be greatly appreciated. Cheers

mate, sounds electricial - check the connectors for the coil packs to ensure there are no broken wires. with the car running, remove the plug into the coil pack of no.1, it is is worst, than no.1 is fine. repeat through to no.6. when you remove one that makes the motor run no worse - then that is the likely coil pack that is breaking down.

It may not actually be the coli pack, so check all the wiring closely. if it looks good, then put the good coil pack (the newie from Nissan) into that location and see if is still misses on that cyl.

if so, than is it the loom for that plug somewhere. if it fixes that cyl, then it is the coil pack.

let me 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.
