Good afternoon,

I hope everything goes fine in Sweden, i'm Javier form Madrid, Spain.

I've found that the OG900 can be upgraded to T5.2 & T5.5.
I own a 900 "91 with Bosch 2.4.2 and EZK ignition and i wanted to know if there's a guide with the things that need to be done.

As i know you need to bypass the old wiring and conect T5.5 and you need to install a crank position sensor.

I wanted to install a turbo engine with Bosch 2.4 ECU and manage the engine with T5.5.

¿Could somebody help me, please?

I don't no Swedish but it does not matter, i can manage to understand.

Thanks in advance.

Best regards.

Javier
