balla Posted January 4, 2012 Share Posted January 4, 2012 Does anybody know what mods would be.needed to fit a r32 rb26 engine in to my 350 and if the gear boxs will pair up Quote Link to comment Share on other sites More sharing options...
Ian Posted January 4, 2012 Share Posted January 4, 2012 First thing you need will be deeeeeeep pockets. Custom engine mounts as RB is a lot longer than the VQ. WIll need to make a custom wiring loom & I still don't think the issue with the tach has been resolved yet by the few people who have done it. RB25 gearbox will be needed. Dont forget that the RB is an engine thats designed to work in a 4WD car & the VQ is RWD. I looked into doing it a last year, its cheaper to buy a skyline. Infact its cheaper to buy a skyline and keep the Z Quote Link to comment Share on other sites More sharing options...
Lexx Posted January 4, 2012 Share Posted January 4, 2012 You'd need a mounting kit, all the RB256 ancilleries (rad, intercooler, fueling etc etc) And you would a suitable gearbox. So far as I know, the VQ gearbox wouldnt come close to fitted a RB. I would suggest doing some serious reading over on my350z.com as it has already been done over there.

Ian Posted January 4, 2012 Share Posted January 4, 2012 If you are serious about this, get in contact with RIPS in NZ. I was in talks with them last year about fitting a RB30 to my Z & they seemed to think it would be easier than a 26. There was a UK tuner that I used once & we discussed it & they were very keen to try it out but I wouldn't trust them with a push bike let alone a car Quote Link to comment Share on other sites More sharing options...
balla Posted January 4, 2012 Author Share Posted January 4, 2012 I don't understand the need to make a new loom couldn't you use the r32s and just use.the dials as.well also would a gtst gearbox fit because im lead to beleave that they are only rear wheel drive Quote Link to comment Share on other sites More sharing options...
Lexx Posted January 4, 2012 Share Posted January 4, 2012 You're asking on the wrong forum really mate. Since no-one here has done it. As I say, go over to my350z and do some reading, then contact Abbey Motorsport and see what Mark has to say about it. In all honesty, unless you happen to have an engine and gearbox sat at home already you would probably be better just getting a TT kit for the 350 if its just power you are after.

Ian Posted January 4, 2012 Share Posted January 4, 2012 So your planning on using a R32 engine, a R32 wiring loom, a R32 dash - just buy the bloody R32 it will be cheaper Quote Link to comment Share on other sites More sharing options...
balla Posted January 4, 2012 Author Share Posted January 4, 2012 Ok thanks and the reason im asking is because the money we need to spend to get power out of the z thought you can pick up a rb26for cheaper and im a mechanic my self so would do the swap at home Quote Link to comment Share on other sites More sharing options...
Ian Posted January 4, 2012 Share Posted January 4, 2012 If only it were that easy, I learnt the hard way. Have a read here http://my350z.com/forum/shop-builds/454 ... -swap.html Theres also a 4wd G35 kicking round the states somewhere with a RB motor in it. I'd love to see someone do it over here tbh but its not gonna be straight forward. Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted January 4, 2012 Share Posted January 4, 2012 It is a job that can be done and the tachometer issue is pretty easy to fix; RB25 gearbox , RB25 sump , R32 Wiring loom/ECU. some fabrication work to make it fit; I see the job done before and it looks pretty good when done properly.

Dblock Posted January 4, 2012 Share Posted January 4, 2012 Just a suggestion but what about a 2jz I know they are heavy but they are powerful and realiable. Also a few people have converted them so there is more info around. I'm not sure about this but was told to hey power from the rb26 you still needed deep pockets. This is 400bhp plus. Can you confirm or deny this Ok thanks and the reason im asking is because the money we need to spend to get power out of the z thought you can pick up a rb26for cheaper and im a mechanic my self so would do the swap at home Quote Link to comment Share on other sites More sharing options...
Neilp Posted January 4, 2012 Share Posted January 4, 2012 I spoke to apex about this and they advised to avoid. They said the rb was a nightmare to work on when it won't wrong and that's why try ripped it out the time attack car and put in a v8 block Quote Link to comment Share on other sites More sharing options...
balla Posted January 4, 2012 Author Share Posted January 4, 2012 The rb26 is such a tuneable and reliable engine no care is nice.to work on when it goes wrong and the vq look worse from pics I've seen there is more room to get around it. if and when i buy a engine ill be doing a rebuild anyway Quote Link to comment Share on other sites More sharing options...

Freebird Posted January 4, 2012 Share Posted January 4, 2012 Imo id just go for a V8 if I was doing an engine swap, an LS lump would be far superior. Then you could always go down the forced induction route on that for even more power. Like others have said I can understand the thinking using an RB26 but, a V8 is a much better option and there are (as far as i know) off the shelf conversion parts available. Also just think of the sound nom Quote Link to comment Share on other sites More sharing options...
Lexx Posted January 4, 2012 Share Posted January 4, 2012 A LS1 conversion using a GTO/Monaro as a donor is very doable, and there are conversion kits available from the US. 380bhp standard, 440 bhp with new cam, headers, exhaust and EFI-live.
