khughes Posted October 10, 2009 Share #14 Posted October 10, 2009 (edited) Kent is the current record holder for slow projects, he has about 17 of them on the go :laugh:Hehe speaking of projects.. i may have just today picked up a forged RB26 for the Z :paranoid:The RB's fit pretty well into the C110/C210's. If your going RB25, i would recommend getting a Greddy or similar front facing plenum (which helps with height and plumbing). RB25DET boxes are big, but fit well.. RB25DE/RB20DET boxes are a little smaller and cheaper (and weaker..). You need a custom set of engine mounts, Gearbox mount and driveshaft.otherwise there are not any real clearence issues with the RB's (The only issue i have with my RB26 is that the oil sensor is fouling on the power steering box i have, but that is not standard)of course.. with any "big" engine upgrade you should also do brakes, diff, half shafts etc. to suit be carefull if you are looking at doing the RB30DET.. it would be almost impossible to get the car engineered (since the engine is a hybrid and therefore has no EPA data).. i believe that the majority of people who do it, illegally either modify the engine number to match their old RB one or just do it and hope nobody notices the wrong engine number (which would be hard considering they check when doing greenslips/blueslips). Of course that isn't a problem if the car is already registered with the RB30, but you are still heavily modifying the engine and still have to deal with the EPA issue.. EPA fines are HUGE too, if you do get caughtI originally went down this path, and then gave up as i wasn't prepared to do the above.SHM17Y, if you need a gearbox xmember to fit the RB25DET gearbox, send me a PM Edited October 10, 2009 by khughes Link to comment https://www.classiczcars.com/topic/33342-rb-conversion-in-76-240k/?page=2#findComment-297134 Share on other sites More sharing options...
24TKman Posted January 17, 2010 Share #15 Posted January 17, 2010 As stated HybridZ.org dont have very much info on the K's. I fitted a RB20det into my 240k, Sold it to a mate & bought a RB25det half cut . ive already modified the crossmember when i fitted the RB20, will the rb25 use the same mounting points as the mount look totally different?? when others have done the conversion, what have they done with the wiring? since i got a half-cut i have the whole loom- what would be better, tap into 240k wiring using original wiring, or change all 240k plugs (lights, dash, accessories) onto r33 loom (is it possible)??

Mr Camouflage Posted January 17, 2010 Share #16 Posted January 17, 2010 I think the first thing you need to do is get wiring diagrams for both cars and work out what wires need to be connected.I remember a 240Z swap in one of the car mags, they didn't bother with trying to wire the original gauges to new loom, instead they molded in the skyline gauge pod into the z dash, which might be an option for you with the K.

khughes Posted January 19, 2010 Share #17 Posted January 19, 2010 (edited) i am not up to the wiring stage yet (will be soon).. ages ago i bought a full R33 body wiring loom that i was looking to retro fit.. but it really is too hard to work through..I am going to end up replacing the factory wiring (there isn't much in there) and custom wiring it all up.. the hardest bit will be the switching of the blinkers/wipers/headlights.. oh and the ignition keyi am replacing all my guages though.. if your keeping standard then you will have to mess around trying to get the right gearbox output cog to match the diff/speedo Edited January 19, 2010 by khughes Link to comment https://www.classiczcars.com/topic/33342-rb-conversion-in-76-240k/?page=2#findComment-306611 Share on other sites More sharing options...
24TKman Posted January 19, 2010 Share #18 Posted January 19, 2010 ive decided to use the original wiring for the car and the r33 loom to run the engine (easiest way imho) stripped the loom back last night using a guide from another site i found, very straight forward. Putting the motor/gearbox in tonight now with the dash/instrument cluster, im sreiously thinking of modding the R33 dash and fitting that to the 240k as this would be the easiest way around guages/speedo, which is a pity coz the 240 instrument cluster is one of the best parts of the car imo! otherwise i could try my hand at fitting the R33 guages into the 240k cluster, but risk screwing everything up!?! :stupid: Link to comment https://www.classiczcars.com/topic/33342-rb-conversion-in-76-240k/?page=2#findComment-306678 Share on other sites More sharing options...
khughes Posted January 19, 2010 Share #19 Posted January 19, 2010 be sure to post as much specifics as you can (especially in regards to the 240k - engine connections), it will be very helpful for plenty of people are you going off the hybridz chris rummfeild thread?i would imagine a R33 dash would have to be pretty hacked up to fit a 240k..

(makes the engine look much tidier imo):classic: gonna need a gtr style plenum for bonnet clearances i can see already Link to comment https://www.classiczcars.com/topic/33342-rb-conversion-in-76-240k/?page=2#findComment-306691 Share on other sites More sharing options...
khughes Posted January 20, 2010 Share #21 Posted January 20, 2010 are you running an RB25? when i was goind down taht path, i ended up buying a greddy plenum for around $800 shipped from the states (years ago now).. easy to fit and gave really good clearanceThere are chinese knock offs, but they are mostly not worth the money once you take into account the bad fitting and the amount of extra work cleaning them up and finding all the parts that are missing Link to comment https://www.classiczcars.com/topic/33342-rb-conversion-in-76-240k/?page=2#findComment-306781 Share on other sites More sharing options...

SHM17Y Posted January 21, 2010 Author Share #24 Posted January 21, 2010 (edited) i realy need to get off my arse and buy myself a 33 halfcutill be using a greddy plenum, but only cos my mate has one sitting in his shedas for the dash, i would hack the 33 cluster to get it fit, minimal bracketing etc, jus get it in there to get yourself driving then build up a new cluster, use the datsun one but get aftermarket gauges that fit in, as the money comes in buy a new gauge, mount it properly once the cluster is full / got what you want in it, wire it inthats how i would do it Edited January 21, 2010 by SHM17Y Link to comment https://www.classiczcars.com/topic/33342-rb-conversion-in-76-240k/?page=2#findComment-306943 Share on other sites More sharing options...
