Hi all,

I'm looking at making a change from my 1995 850 GLT to a 1996 850
Turbo. I looked at the Turbo car today and had a peek under the hood
and noticed the engine (from what I could see) appeared to be the same
as what I have in my GLT but with a turbo bolted onto the back.

Is there an actual engine difference? I also noticed the 1996 doesn't
have the OBD interface under the hood the way my 1995 does... can this
be retrofit or transferred from a 1995 or will I need a whole new
wiring harness?

Thanks in advance,

The engine is very similar, but there are critical differences. Lower
compression ratio in the turbo engine, fittings drilled in the block for
oil feed and drain, different computer, different injectors, plumbing,
other small changes.

Can't help you with the OBD, never messed with it. Where is the
interface on the '96? I thought all cars that new had to have one?

The OBD interface on the later 850s is under the coin holder on the
central console.

Thanks guys. Yes, like the '95, the '96 Turbo has the OBD jack under
the coin holder in front of the shifter. BUT the 1995 has a "self
diagnostic system" under the hood mounted on the left side that allows
you to connect a jumper, press a button, and read the codes off
WITHOUT an OBD device (just count the number of times the little red
light flashes).

It is THAT which is mising in the '96 and which I would be keen to add
if it's just a matter of getting the part and plugging it in. Again,
if it's crazy wiring harness work then fugeddaboudit. I could see the
mount for the unit is there but the unit itself is not installed.

Thanks,
