34 de+t conversion using s2 stagea automatic transmission, engine harness and ecu

[albyz34gt]

Hi alll im new here.

 

I've been seaching here for days and can't find what I'm looking for so I hope someone has some knowledge they can share. 

 

In looking to +t my na neo 34 sedan.

I've purchased the complete turbo setup off a late 98 (series 2) rwd automatic stagea.  So i have the hot and cold side, ecu,engine harness and the auto transmission. I realy want to keep the car a nice cruiser that's why I want to keep it auto.

 

I'm hoping someone here can confirm I can use all this in my 34. Or point me in the right direction if I need to modify the engine harness to plug into the 34 body harness.

 

Any help would be great. Thanks guys.

Does the stagea have the gearbox control in ecu or separate controller?

A mate did this conversion and went a r34gtt ecu with Nistune and added a few resistors and diodes to ecu loom to give ecu a few fake signals and gearbox uses factory controller.

That setup has worked well but is all being removed for  a Link plugin and 8hp50 conversion soon

So the stagea was a series 2 neo det with tiptronic auto. (I have the transmission aswell) and has integrated tcu in the ecu. I'm hoping to use the entire stagea ecu, engine and auto harness.

If the original NA ECU has a separate TCU then you are going to need to reroute wires that used to run between the trans and the TCU to the appropriate (1 to 1 equivalent) pins on the ECU. Other than that, it should work.

Look up posts by @Kinkstaah on the subject.

@GTSBoy totally unrelated but I am unable to message you privately. Do yoy know if the r33 turbobox and r33 na box have the same tailshaft yoke? Can I use a 34 na shaft in a 33 turbo box?

You need enough post count to have PMs enabled. It will come.

They are not the same. The NA box is the skinny little box and the turbo box is the big heavy one, and the yokes are not interchangeable.

Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue. 

Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?

 

Cheers guys

Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator.
