Yes, the firing order problem is solved, but the fuel injection ECU still needs some fine tuning.  CB emailed a custom tune, but as we know each engine is slightly different, so adjustments will have to be made for optimum drive-ability.

 

I hope this 901 5 speed is worth all the hassle.

Carl, with install is not an easy one.  My mechanic, who has many years experience working on Porsches and was at one time a service manager at a VW dealership, is  surprised at the number of little problems that have cropped up.

One of the biggest obstacles was finding a way to lockout reverse gear on the 4 speed shifter, without having to rip out all the carpeting to modify the tunnel to fit a Porsche 5 speed shifter.

He ended up going with a solenoid on the tranny that pulls the reverse lockout when the button on this shifter shaft is pressed.  Cool idea, but we don't know how well it will work.
