Later Euro cars have door beams and a lot had power seats too, but cruise and aircon were indeed not such popular options. The car I'm looking at has UK headlamps too. It's a cabriolet (with aircon & cruise).

From what I can see, the only issue here is the transmission oil cooler - which ought not to matter too much -after all the 204 bhp SC managed without one for its 915 gearbox, so an extra 3bhp shouldn't make a difference.

...which is all good news (I'm not going to track it - I have a choice of 2 Caterhams for that)

Thanks for your help and any further comments are most welcome

IMHO the north american cars are not only less attractive with respect to performance (after all Porsche is about performance) they are as well less attractive to look at -higher ride height, huge bumper impact strips,different coloured marker lenses,no rear fog lamp,and of course no h4 headlights (not in this case )

US Carrera 3.2 MY 84-89 9.5:1, 207 bhp
US Carrera 3.2 MY 84-89 9.5:1, 218 bhp due to a remapped ECU

ROW Carrera 3.2 MY 84-86 10.3:1 231 bhp (no catalyst)
ROW Carrera 3.2 MY 84-86 9.5:1 231 bhp (no catalyst) same bhp due to a remapped ECU.

The US engine is the same as the ROW but wirh catalyst and it would be possible to retain the lost bhp by remowing the catalyst and remapping the ECU.

I have sucessfuly done this with an US car.

Oh, and a couple of more things,


If the car is in good shape, you might find it worth the effort to correct this and you can easily do this in an afternoon.

Performance: corrected
Ride height: corrected, lowered
Huge bumper impact strips: Yes they where hideous but are replaced, simple task.
Color marker lenses: Doesn't bother me
No rear fog lamp: Doesn't bother me, quite the opposite
No H4 headlamp: Replaced

how many minutes to change the compression ratio?

Dear ms/mr creaturecat,

The compression ratio was only higher in the models MY 84 to 86. After that it was the same. Look at the post above.

As many have stated, the key reason for the increased Euro torque resulted from
the increased compression ratio. As a result of this, more potential problems occur
when chipping those engines. It's also correct to state that Porsche updated the
fuel/ignition maps in '87 and then again in '88-'89. The '87 re-mapping gained about
7 ft-lbs of torque which gained about 7 HP over the '84-'86 models. The '88-'89
re-mapping provided more data points to determine the optimum fuel/ignition
settings which resulted in a smoother overall engine.

Most Euro cars in the U.S. were "mickey moused" to include the O2 sensor.
It's a costly effort to correctly modify those cars to properly pass the emissions
tests. Over time, fewer and fewer cars in all the states will be able to pass
(visual & probe) without the CAT and the stock chip (NOx failures). The bottomline:
The government (you & I) doesn't want these old cars on the roads anymore
especially the ones that have been modified. The days of modified cars have
ended, e.g. '96 and later OBDII cars.

Dear Loren,

Except if you live in Sweden where it's permitted to remove (though I have kept the O2 sensor) the catalyst if the car is MY 88 and before.

So Loren what's your opinion of what to do with simple means and a possibility to remove the catalyst to regain as much bhp as possible on a 930/21 from MY 1986? And also how much bhp and of course torque would you gain by your suggestions?

Looking forward to your soon reply.

Best regards
Anders
