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????

[lilly-tyler]

can some one please help me!!!!!

You don't need a computer unless you are modifying it. If you are a plug and play r32 GTR computer. Use R32 GTR coilovers and not the GTST.

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.

ok thanks but will i have to moddify anything to put a stagea auto gearbox in it as the rb20 when has shat its self

[DR 32R]

You can have the auto rebuilt, better to go with someone who likes JATCOs, what state are you in?

[lilly-tyler]

im in qld and i have started modding it , it has a full 3inch exhaust,fmic,and pod filter and turbosmrt boost controller soon will have bigger injectors and high flowed turbo

as for the auto ecu i have a rb25 auto computer running the motor previous owner had a rb20 ecu running the car

should i just get a apexi power fc for a gtr???? when i get the new auto??? will this work

[DR 32R]

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.

[lilly-tyler]

ok thanks so i defently get a ecu that is ment for the r32 gtr? abd how will my gearbox go being an auto with the aftermarket computer?

[Chris Rogers]

not on the ECU. do you know EXACTLY what engine is in the car? gtr is different.

[Sarumatix]

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.

well i have just found out i need to get a stagea box out of a seris one so its not tip-tronic would be less hasle.

+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...

im just going to get the auto that aint tip-tronic from the stagea and get the auto computer at the same time and maybe the ecu aswell then give it my local workshop GODZILA MOTOR SPORTS they should be able to sort out all the problems for me and give it a good tune, they know there skylines preety good!

[Chris Rogers]

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

[lilly-tyler]

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!!!!

[DR 32R]

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.
