Hi all, I just have a couple of queries regarding the engineering certification process for a RB25DET 240z in Victoria. I’ve done some searching of old posts and found some good info but nothing which covers the exact questions I have…..so here goes I’m relatively new to Melbourne (and Australia) and am looking for some advice from people who have/or are in the process of performing this conversion for a road-registered vehicle. I’m from NZ, and from what I’ve read through of the Vehicle Standards Information (8 – Guide to Modification for Motor Vehicles) available from the Vic roads website, the Approval Certificate system is fairly similar to what I’ve had to do in the past in NZ. My main concern after reading through the document is the reference to the emission regulations. From what I understand the conversion would therefore have to meet the level of the car (R33 GTS-t) from which the engine came from. I would prefer to do away with the factory Skyline airbox, cat converter, engine management, turbo etc…. So my question is - are the original engine’s parts required for an Approval Certificate? My main concern is the ECU, as I don’t want to run the factory engine management. I did see a post that referred to pre ’76 cars not requiring an emissions test regardless of the engine being used (however all emission control equipment that were on the original engine must be fitted) - is this correct? Also, I’ve seen a number of other cars around with ‘Club Permit’ plates – how does this system work? (Is it more relaxed on modifications?). My intentions for the car are for it to be primarily used in the weekends and for circuit/sprint racing (it will not be a daily driver but must be able to driven on the road). Thanks, Craig.

Hi all, I’ve just recently become the owner of my first 240z, having purchased Nate’s 73 240z. I’ve always been a fan of the Z car, but up until now I have owned and modified Datsun 1600s. I’m originally from NZ, and have been living in Melbourne for around 18 months now. I still have a SR20DET Datsun 1600 which I had been building in the garage in NZ (as pictured below), but it will continue to gather dust for a while now as I begin work on the 240z project. I’ll be converting it to run an RB25 with similar suspension and braking modifications as I used on my 1600. I’m still researching and absorbing many of the key points of the engine conversion and I’m sure I’ll be posting and searching the forums for info. Thanks, Craig
