I got a r33 gts............

I'll be buying a rb25det engine off justjap auto and putting it in my car......will it be a direct conversion...or are there any other things to change???

please advise me...

Well the reason I said that was because when I was looking at doing it the engine package was $6-$7K...they're a lot more reasonable now..but it's still going to be at elast $2K to put it in.

The best option is to make an RB30DET out of your N/A engine

Great thread,

I too made the same mistake, that is buying a N/A skyline except mine is and R33 GTS. I am desparate to turbo my engine, however my local mechanic has told me that you cannot turbo the N/A....that is without ruining the engine! Reading this discussion has helped me see what can be done to the engine, with a low cost outlay and surprising gains, Thank you!

However I have a couple of questions,

How does the car now drive?

Is it as reliable as the N/A?

Are you sure that the modifications will not damage your engine?

cannot wait to get my project Turbo underway. :flamed: :flamed:

DanielWilliam: The car currently pulls harder than a stock GTS..this is with the crappy N/A exhaust still in place and running 6.5psi that is probably down to the higher compression :(

I've had the turbo on my car for about 50,000Ks now and nothing has been damaged in that time, from a reliability point of view I think that's great. If the tune is good, you should have no problems...just don't expect to be able to cram 14psi in and you'll be fine.

Great to here that Dan,

It has put to rest the only real concern I had after reading the thread (the longterm future of the engine).

Sounds like the car goes real hard compared to the N/A You had and I have now, mine came with a full Trust exhaust out of Japan which will hopefully complement the turbo well. All I have to do now is get the funds together now and I can start the project.

I guess it is like you said tuning is the difference the car will run well and hard with some dollars in the tuning side of the car!

I will keep you informed to how my conversion comes along. I have some pics of the car in its current state in my gallery.

Cheers mate

If anyone is interested I have everything you need to do this swap

Off an RB25DET

Exhaust manifold

Turbo (No play)

Oil/Water lines

std dump pipe

Inlet manifold/Plenum

Fuel Rail and injectors

If anyone is interested in these PM me and i can send you pics

reason why i am getting rid of them, upgraded to GReddy plenum and getting top mount turbo setup

That list could make my shopping very easy!

That stuff is exactly what I am shopping for at the moment, what sort of condition is the lot in? whats your location in relation to Newcastle? Also with the condition of the parts in mind what is your best price?

Cheers :P

    • 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"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
