RB Engine conversion
« on: July 21, 2012, 05:54:05 PM »
So it looks like with my Cf facelift im back to square one on the Rb20e conversion.
on the original conversion the wiring was a dodgy ass hook up to get it running and drivable which worked for a short amount of time, which caused many issues with it so it was time to do it properly. I scored an R31 skyline that was a jap import which had been written off from a smash and stripped  of everything to rewire the CF and get it running and driving properly but as time has gone on slowly myself and cfjeff have found more issues with using the wiring from the japper more issues than i thought it would be. turns out when stripping the car some crucial bits were missed and to get them would have to be ex japan but without part numbers it became more of a headache (and unfortunately parts out of the Aussie assembled R31s n vl's don't mate up to the jap assembled ones) and work on getting the van running came to a stand still for the last few months.
 
Finally after 18 months of struggling with the japanese mission, Today came a light at the end of the tunnel i picked up a complete VL commodore running a RB30.
So the next step is to tear my van right back to the start and do it all over again and repower it with the RB30 since the mounts for a RB engine are already there. While doing it i will try and post plenty of photo's and update it regularly for those wanting to do the same thing in their van.
 
First step will be tearing my van back and stripping the commie out so watch this space

10 steps back but at least this time i will get where im going finally

so it began ......again lol
 this time the strip down of the VL, with the help of cfjeff - who has been a great help with trying to sort out the van and its previous wiring from the R31.

armed with a roll of tape and a marker pen slowly i made my way round the engine bay, taping and marking every plug i came across (dont feel like a repeat of last time with the R31 skyline) so that way when transferred to the van we will know were it goes this time round. Once Jeff arrived he set to  on the dash and interior pulling it apart n marking it up the wiring as he went. the VL has definitely been a better choice for donor as everything has its own loom - power window loom, engine loom, rear light loom etc unlike the R31 passage, the previous donor - everything was one great nest of wiring which meant a lot of unnecessary wiring/crap to deal with. the extraction of the dash and centre consul was alot easier than the skyline as well - the japs seemed to have screwed n bolted it into the skyline anyway they could lol.
 Haven't quite began to dismember the VL yet but that will come as i am yet to clean out the skyline gear out of the cf.
 but the main thing is we have made a start on the right track to getting it running and on the road finally.

few shot's of progress so far included
 note photo 3 is not of my interior - forgot to get a photo before it got pulled apart

time for an update as ive achieve a little bit over the last few weekends
firstly i had to strip out the wiring n custom dash that i had already put in and spent many months trying to sort out to no avail.
which luckily didn't take too much work to strip out.
next came the auto which came out fairly easily with the aid of a trolley jack.
and finally the motor which just ended up falling out as i was jacking up the rear to balance it out so i could lift it out from the front a notch too far
and it just rolled out onto the lawn with a great thud leaving a great hole where it once was mounted.
