Converting an H6 to 5 speed

Featured Replies

I've got an '03 H-6 from an LL Bean mated to a '03 turbo 5 speed and noticed there is no pin that indexes the flywheel/crank together. Is it OK to run it this way? TIA, kent

Fine. Flywheel can be mounted anyway. No need for alignment just get it tight

Good luck! It's not going to be an easy road. Granted, you can bolt everything together but the computers will not be happy. ECU will be looking for 3 different signals from the TCU and without them, prompt a CEL.

Well don't go anywhere. You sound like you know your stuff and I certainly don't. :wacko: I had hoped to avoid most of this by swapping out all of the wiring & ECU from the donor. Using what I can, cutting out the rest. Hopefully unrelated codes can be flashed out?? BTW,   :ph34r:   this is all going into an old Porsche. Even the donor car's steering wheel. I know. Wrong forum for this. Just got off on a tangent.

There must be some way around this - I got a JDM manual EZ30 Legacy in at the auction house the other day direct from Japan. They do exist, so there must be a manual TCU out there that can handle the EZ30.

Shuld have specified, all Subarus with a flat 6 EXCEPT the XT6, had an automatic transmission coupled from the factory available in the US. I have seen the manual 3.0 overseas but nothing that was offered here.

 

I have seen guys do the swap into VWs and an XT6 but I believe there is a bit of a tuning issue when the engine computer waits for a signal from the transmission computer for a shift point. Im not entirely sure how it was handled using a stock ECU but if I were doing the swap myself, I would be running a MegaSquirt 3 box.
