Hi guys, 

looking for opinion if that worth to swap vq30det instead vq25det? i couldn't find any topic with similar project, i wonder if awd system will work properly and gearbox will fit straight? idea is that solving issue with ecu tuning as vq30det is supported by nistune, actually some will ask why change the engine instead of buying ecu? but first i couldn't find any ecu for that and second i have spare vq30det engine already)

I didn't know Nistune supported Y33 VQ30DET, interesting...

From info on hardtuned (and another SAU thread) the Y33 and M35 ecu pin outs are pretty different. And from my understanding, the Y series ECUs control things like the climate control and part of the navigation display. Not sure about the M35 but you risk losing some of the interior functions. Not to mention the new ECU would probably need info from the auto box, and M35 runs RE5 while the Y series all run RE4.
Sounds like a big task and lots of unknowns.

Doesn't really help you but the only VQ30 into Stagea swap I know about used a Link ecu and manual box from a Z (so RWD)

I have recently put a Haltech Elite 2500 in my M35 with the VQ25DET, i believe it is the first to have it done in the country. I have been working with Matt from Haltech to clean up and sort out the base map for the computer, which was a sucess. The car is now tuned and it runs beautifully.

Anymore details? Is it just acting as a piggyback?

Mine isn’t yet, but it can be added in, after the motor is wired there still are a few available outputs that can be used for what ever you please. If you run out of outputs you can get a CAN hub and add more.

      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.
