another thing is its a auto but the gearbox is a rb20 gts4 one its slipping reall bad me and mate checked fluid levels and didnt have much in there so we topped it up

and it seemed to shift better but when it would try to shift into third it would slip reall bad as soon as i got to put my foot down

but if i use it manually and put the shifter into first and put my foot down it doesnt slip nor second????

could the fluid leves still be out would this make a diffrence???or could my fillter be cloged or do i need a new auto???

and would a stagea rb25 gearbox bolt straight in????

I have an r32 gts4 4 door with an rb25 in it, if I was looking for an aftermarket ecu id go the vipec,i'm running that in mine. After the issues were sorted it was good, and awd seems to work okay. I'm running Tein HA/HR's in mine, but it came like that. I'd guess they'd be the GTR ones.

why an aftermarket computer?

unless you are going to mod the thing I personally would not bother. you have more pressing issues with that box. if its slipping then NO amount of fluid will fix it.

you have 3 real options:

fix it - $4k for a jatco 4 spd box.

sell the car

put a GTR manual box in it with rear diff.

if you have a RB25 in it already then you have a stagea engine in there. box will bolt to it though I'm uncertain of the electrics if you are going to leave it as an auto.

manual will give you less hassles and the autotrans is not reliant on teh engine ECU for control. the staega ECU will run the trans if its a later one.

as for suspension - GTR items.

Only in my opinion, I think the Vipec or Haltec e11v2 or Haltec platinum, plug and play for a GTR would be better. If you're getting a tune, what your tuner likes of those two. I'm glad to see another GTS4 being built. They're nice cars.

Ya i'm getting confused trying to follow this :). Find the part number on the ECU.. match it up to this thread -> http://deniliquinsportingcarclub.com/index.php?option=com_content&view=article&id=58:rb-ecu-part-numbers&catid=35:nissan-skyline-information&Itemid=9

Secondly I believe to run different autos you need the associated Auto computer. It isn't straight forward and most people don't even bother trying to swap autos to later models, but I have seen cars that say it has been done (as in tiptronic into R32). Therefore it is better to rebuild what you have (which will probably cost upwards of 3G).

Furthermore because of the auto, usually you are locked into the Nissan computers. However some ECUs can easily be remapped using Nistune, once you find out exactly which ECUs you have that run the car, try and use one that can be Nistuned, that will save a lot of headaches.

+1 to Nistune!

my cousin used a Z32 ecu + nistune in his r33 GTS4 with 25DET transplant (from a Stagea).

His car is manual however...

whilst I'm not going to tell you how to spend your hard earned :)

I would sort your existing probelms first BEFORE fiddling with the engine. bob grant automatics will do the jatco and make it bullet proof. I have already have one box doen by him and its the bset shifting box I have ever used. (subaru 4spd auto.)

buying a second hand box is going to be buying another hand grenade. it will work for a while then spit 2nd or 3rd again.

do it once and you will not have to do it again.

from there then start playing with the engine. no point upping the power if the device behind it will not take it.

as a parallel story:

I bought a 88 subaru wagon - dead engine in 2006 - dropped a twin turbo awd ut into it - 4 spd auto. box lasted 3k before it spat second.

when it did the whole thing went. turned out second gear band was worn to metal and that filled the box with shavings and destroyed every clutch in it

every box I looked at second hand was trashed or near enough to it. it sat for two years whilst I was looking in the end I put $4500 into a totally rebuilt box and that had everything uprated and a BIG trans cooler added. that was feb 2010 and it runs fine now and has not given me ANY trouble.

looking at your current idea you apper to be ready to simply throw money at it without a real plan. I would plan what you want and from there work to achieve that.

as a marker have a look at the GTS4 thread in my sig. that is a plan in action :)

i know what u are saying but for now im just looking to get it on the road as a everyday car so wont be going down that path for awhile.

but i have been doing a bit of reaserch and have found out that seris 1 stageas dont use tip-tronic so im going with that less hassle and i will be getting the stagea ece and auto computer

in the future the gearbox will be getting work done to it just not keen on doing any work to the rb20 auto would rather spend the cash on a rb25 one

just want it do drive good for now then get it registed and on the road.Then ill start the big mods lol!!!!

I think Chris loves gts4s and is trying to point you in the right direction. He has both trade experience, and a love of his own restorations, but especially his gts4, check out his thread. I think the easiest tranny, is rebuilding the one in the car. A properly built JATCO is well proven in the VL drag scene. Cheers.

True but they probably "farm out" any auto transmission work.

    • 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"
