Changing '95 993 Motor to OBD2 brain? Doable? Options

[SirAndy]

My '95 993 Motor is a pre-varioram OBD1 Motor and i have been toying with the idea of updating it to OBD2.

There was, for a short time, a OBD2 brain available for the (still aircooled) 993 starting in '96 with the varioram version of the motor.

It is my understanding that besides the tubes inside the intake, the two motors are pretty much identical.

I wonder if i could get a later brain and harness and make it work with my engine.
Is there anyone out there who has tried this?

The basic hard parts of the 95 and 96-98 993 3.6l motors are mostly identical so there should be no issues there.

Are you planning on using the vario-ram intake on the 95 993 long block? If not, why do the coversion?

Also, the ODBII exhaust has additional O2 sensors that the 95 exhaust doesn't have. You'll need to either source a later exhaust or weld in bungs.

Honestly, what will you gain with the ODBII upgrade besides the 10 hp from the Vario-Ram? I am very interested as I have a 95 993 and chose it to avoid some of the problems associated with the ODBII cars.

Very interesting idea, BTW.

Why do the coversion?

I have access to an OBD2 wireless data logger chip that uses satellites to communicate in real time to a central server that lets you stream the data into a customized Google maps webpage.

Real time position tracking, acceleration, braking, g-forces as well as any engine related data available from the brain. Rpm, ignition advance, pressures, temps, error codes etc.

And because it uses satellites there's no need to be within cell phone tower range. Works pretty much anywhere.

And best of all, it's all free of charge!
