hi all.

i have a 300zx z31 the engine is all but dead.the engine will cost more then the car is worth to rebuild.

i was thinking maybe sticking a rb30e in it i'm not after power just something i can get parts for at a fair price plus there's planty of skylines and vl commodores around for cheap (not like vg30e that are hard to find then had the sh@t thrashed out of them).

has anyone done this convertion? i know i will have to mod the crossmember/engine mounts,sump and g/box mount and so on i can do all that stuff.i have talked to an engineer and he has no problems with the idea.

my main concern is the ECU will a skyline ecu plug in or has anyone ever rewired a skyline/vl ecu in to a z31 when they have done a rb25/26 det swap to a z31.

thanks.

ps i know you's will say do the rb25/26det swap 1st but at the moment the dollars don't allow that much cost plus the engineers cost.rb30s are cheap i can allways swap it later on or do the top end swap later

i am in the process of doing a rb20det swap into my z31 300zx you will need to change the sump oil pick up mounts and cross members very hard to find

if your after a running vg30e out of the 300zx z31 i have one

just throw a ctn of beer my way and it's yours

You'll need a reverse sump and pickup out of the 200ZR to fit the RB30 in it. Not sure about deck height and how close it will come to the bonnet. There is a custom sump and pickup and cross member I think on boost cruising for sale for $600 (No it's not mine)

    • Bump on this to not make another post, had a ‘head drain’ leak on me and have the engine out as we speak. Planning on just putting a new freeze plug back in , plug the tapped holes and just be done with that headache.    Now I still want to relieve pressure to allow oil to pass down the blocks returns easier. I’ve seen catch cans with multiple vents help folks with this issue on this forum.  I’m wanting to make my own. I have some pictures here of my setup if anyone can help how I should plumb and design the catch can I would deeply appreciate it !   rb25 Oil upgrades: 1.0mm restrictor n1 pump/billet gears extended crank collar  extended sump with trap doors/w welded fitting    
    • The Frenchy's kit is the way to go forward. A modern compressor that weighs about 1/2 as much, is at least twice as efficient, and will do a good job on R134a. And of course the kit has everything else you need to connect it up and have it work properly.
    • Hey all , I am in the process of having the AC system in my r32 GTST converted from r12 to r134a and I’m being told my compressor has gone bad and I will need a new one. I was wondering if anybody has any suggestions for what is the best route to go aside from dropping $1500 on a new oem one? I did see that Frenchy’s performance garage offers a kit to mount a Toyota compressor, has anybody actually used this kit on their car? Or is there anywhere I could purchase just a clutch? Any help is appreciated.
    • Well, your RB20 ECU loom won't have wires for the boost solenoid, that boost sensor, and possibly one or two other things. There could be differences in seemingly random things like the charcoal canister purge solenoid, because the 25DET has to handle boost in the vacuum system and the 20DE does not. I don't know - I haven't looked. It is very likely that all the most important things are same-same, being the main sensors like AFM, CAS, etc, and the injectors and ignition. Not that you'll need the AFM for the Haltech anyway. I would suggest that you would seriously want to sit down with the pinouts for both ECUs and just go through them and highlight green what is the same, orange what is different/missing, and make a plan from there. It's not going to be difficult. It will either be the same or need to be fixed.
    • yeaaa that's why I haven't done any wiring to the stock ecu harness because I have the haltech, but then that leads me to the other question of "is the pnp harness really plug and play?" or would I have to still switch some pins/wires over because the pnp is for the rb25det neo harness, and not for the rb20de neo harness. was really hoping to find something to spoon feed me since so many people have done rb20neo + t conversions, but man this is rough.
