S2 Auto Box Into S1

[66yostagea]

I want to fit an S2 RWD auto box into the S1 Dayz which is an S1 AWD that I have converted to RWD. The motor I have just fitted is an RWD type. The S2 is Tiptronic whereas the S1 is not.

Is this easily done or are there a host of mods necessary? ECU, loom etc.

Any help greatly appreciated.

Wiring is different. Trans is different enough for that to become difficult.

The correct trans , also from r33, re4r01a sell for pretty much nothing.

I think you'd be better off buying an aftermarket transmission controller unit if you wish to remain auto, while adding features like tiptronic/manual gear selection. If you have cash you could look for someone selling a built box (someone on SAU was selling a RWD skyline box a while ago)

You'd also be able to control shift points and alter when the torque converter clutch locks up. You could copy the stock shift map (Im sure I have it in a PDF somewhere), and then tweak it to suit. I think the TC clutch could lock up far more often (and probably get better fuel econ as a result)

Thanks for info. Have an awd box i will fit.

A built awd box with a shift kit, a trans controller and custom paddle shifters would be kinda neat

just on the teptronic box i have a r34 4 door it has the tiptronic in it, i am currently building a rb 26 30 with about 400 450 bhp max will this gear box work or will i need to get a turbo box i heard someone say that the gear box dosnt talk to the ecu or some shit if you could shed some light that would be mad

Ask a trans place . An na nox definitely won't last. A stock turbo box probably won't last. A decently built turbo box will last.
