S15 200sx owner Posted April 4, 2005 Share Posted April 4, 2005 Hi guys Well the time has finally come, after much homework and deliberation & negotiation a deal has been done & and the 240z is mine. I have a big road trip north with the trailer to bring back the zed this weekend, then let the RB30DET conversion begin! I have also brought a complete VL holden commodore (with its RB30E engine & 5 speed) for $350 Still havnt got a RB25DE head for it yet (if any of you NZers have a spare give me a yell) Planning on running a GT35R or GT3540 or similar puffer. Looking for 500hp+. So cant wait to get into this. This site has given me many tips and much enthusiasm, over the last couple of years, thank you all!! How do i upload pictures? so i can keep you all posted as to my progress. Cheers. Quote Link to comment Share on other sites More sharing options...
stagefumer11 Posted April 5, 2005 Share Posted April 5, 2005 ahahhhh good to see another NZer' have you talked to rob at rips yet, i do know he isnt keen on giving out information yet on the rb30det as it is he "special" motor. IF you are requiring a head check All nissan parts oh hutt park road, Seview. Not cheep tho. Also look around on the SDu forums, http://forums.skylinesdownunder.co.nz and see what you can find also.

S15 200sx owner Posted April 5, 2005 Author Share Posted April 5, 2005 Hi there Stage where abouts are you based? Yeah i have bounced a couple of e-mails off Rob @ RIPS, I thought he was pretty expensise for a standard internal RB30DET, so bugger it i'll have a crack at putting one together myself, have done a fair bit of reseach into the hybrid engine both on SDU & this site and i think i pretty much have it sorted. The car i have brought has been a race car, i will be building it as a road registered race car, got to be a bit of fun! In the past i have had race cars that have been trailered to the track, but this time i want a car that i can drive to an event (circuit or the odd drag meet) and scare a few people. Whats your car Stage? Quote Link to comment Share on other sites More sharing options...

ZROSSA Posted April 5, 2005 Share Posted April 5, 2005 Cool, Where are you picking the car up from? Is there much of a difference between the rb20 and rb25 heads. rb20 might be a cheeper option if valve sizes are similar or if you have to do major head work anyway. It looks as though there are going to be a few fast zeds around. Might have to form a club and get in some track time. Douglas Quote Link to comment Share on other sites More sharing options...
S15 200sx owner Posted April 5, 2005 Author Share Posted April 5, 2005 Hi Guys Picking the car up from Auckland, I'm in Wellington so it'll be a fairly long haul. The RB20 heads dont fit onto the RB30 block (different bore size etc) need the R32 RB25DE head, its a straight bolt on. Do you guys know of many other RB zeds in NZ??

The RB25DET non-VVT head is a straight bolt on, the VVT head need a little work, but an RB20DE head requires significant welding of the water ports in the head.
