996 Upgrades !

bossmls said:

Hi
Anybody know / reccomend the best tried and tested non destructive engine upgrades available for a 2003 996 3.6? If remap or chip who are the recommended indies / OPC in the Notts area? ( willing to travel for right service). Also how do mods stand with OPC warranties, I read on rennlist some upgrade software is OPC undetectable is this so?

Thanks for your time. Great Forum :wink:

Extracting extra power out of the 3.6 is notoriously expensive. There are some tuners out there (Manthey, Cargraphic, etc) which have been successful in liberating additional horses through new manifolds+cats+induction+ECU remap. But this doesn't come cheap, and has typically been done on the motorsport 3.6 engine as found in the GT3 which is a completely different engine to the one in the RMS-prone regular 3.6. Manthey have quite a few different engine upgrades and all of them are TUV tested/approved which goes quite some way to demonstrating their reliability apart from road testing. It's worth having a look at their different websites to see what they offer.

Porsche did an X51 power upgrade for the 996 which liberated an extra 20bhp or so on the regular 3.6 (this was standard on the 996 40th Anniversary edition). But I think this involved new heads, induction etc and was an £8k+ option from the factory. Not sure how feasible/available the parts are for retrofit.

fitted an induction kit which makes the noise nicer and the throttle seem lighter (claimed 23hp but i'm sceptical).

Sports exhaust next but not sure whether to do back boxes or whole shebang inc headers etc........

More like 2.3hp from an induction kit.

Stu - your Targa sounded great with the red bit. How come you didn't sell it with the car?
