The whole harness will need to be rewired...the ECU's are way different with the R34 being a fussy bastard with respect to having EVERY sensor working correctly.

As long as you've got the manual to work from, it should be easy enough.

I was just talking to a friend this afternoon about doing such a conversion in the future...

pending on circumstances.

the gearbox will need to be changed, wiring, loom, ecu, basically everything that made the

RB25DET run in the 34 will need to be brought over to the 33

lol ur looking at 10grand mate rofl

6 ish for an engine

then u need bigger brakes

better suspension

bigger fuel pump

as eug said a gearbox and thats around 2 - 3 grand LOL

then theres the installation and that aint cheap mate so basically the engine , gear box, good brakes good suspension and fuel pump will set u back 10grand already if u get suspension , fuel pump and brakes 2nd hand then u'll still be looking at 9grand or so, and then installation of the engine and the complicated wiring the r34 contains will set u back a shit load more.

just put a rb25det into my 32 however it wasnt a neo. pretty straight forward although i didnt personally do it. tailshaft needs to be fabricated as does the gearbox mount. needed to get a new pinnion assembly for speedo going from mech to electrical however not sure if u will encounter this problem being a later model car to start with. i know in queensland regulation states u must have brakes at least the equivalent from whateva car the engine is from, personally i went for s15 as being 4 stud they didnt have to get redrilled or anything and are actually even better then the standard 33 objects i think. (dont quote me on it). depending on diff to my require different diff

cheers, matt

gearbox may hold up if ur gentle. but then again whats the point in havin a turbo car huh??? i looked into this b4 and this is a VERY messy job hey. If its what u wanna do, then go ahead, just make sure u got a fair amount of money in the kitty otherwise ur ride will spend a shitload of time in the shed.

Realistically...the extra cost of putting the NEO in an R33 isn't really worth it..just put in an RB25DET from an R33 and you'll save thousands which could go towards a bigger turbo etc etc which will put you way ahead in power stakes than the mroe expensive NEO

i have read somewhere that the neo6 has a few extra goodies like stronger internals??? (dont quote me on that) which means you can probably run more boost) it makes more power stock like 200ish kw? and has a far greater potential than the standard RB25DET

your fuel pump wont need to be changed, my stocko is running my V8 with nitrous, there a pretty good standard pump, You will need to do the gearbox as yours will probably not handle the power as well as the diff, depending on how u drive, i broke 3 diffs with the rb25de though so maybe im a little harsh on the car. theres not much else u need, brakes can be an afterthought and dont need to be done straight away nor does the suspension. Ive had the V8 in my gts with stock suspension for almost a year now, its a little soft but u can make do with it.

About the brakes, it depends on what rules u use, there are a number of sets of rules regarding engine conversions, All i had to do is make sure my car had 4 wheel disc brakes.... Mine definately arent up to the task but rules said it was fine.

Depending on where ur from u will more than likely have to get it engineered.

hahhaa. im not to sure wether ur pullin the piss.... so i'll just clarify it. lol. RB25NEO is almost a direct swap into a r33. Onli difference is coilpacks from memory. U can grab the ECU from the r34, not sure if is reprogramable, otherwise just go aftermarket. Then just bolt on turbo, manifold, intercooler, etc. I rekon u could get away with this option for abt 5k.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
