    993 TT POWER KIT II

    Good day guys; as you are certainly aware of the stock car was sold in Europa with an engine output of 408 hp with the possibility to increase power to 430 and 450 hp thanks to Porsche offered kit I & II. I have been told the kit I could be installed aftermarket whereas the kit II had to be ordered together with car i.e. it was not possible to fit it later. I wonder whether this is true as the seller of a 993TT i'm interested to purschase showed me an invoice related to the installation of a kit 450 cv a couple of years after car's first registration. I fear such a kit is not Porsche original one. Any thought?

    Cheers
    SM

    Re: 993 TT POWER KIT II

    Both kits were available in Germany for retrofit.
    Only the 996 Turbo kit isn't available as a retrofit and it has to be ordered from the factory but I heard that a retrofit might be possible for certain customers (depending on the country where the car is registered) if they're willing to bring the car to Exclusice department at Werk 1 in Zuffenhausen. Unfortunately this retrofit also includes a new gearbox, so add the cost of a new gearbox to the kit.

    Ýou can drop the 430Hp and 450Hp kit at Porsche whenever you want. The 450Hp kit includes ECU, new bigger turbos and new oil cooler together with other minor mods. I've seen two 993TT with those kits and both were insttaled as a retrofit, even car papers mention the upgrade, this is a comun situation, don't be afraid.

    Thanks for yr ppt replies. May I ask whether you hold datas regarding performance of 993tt with 450 hp power kit installed? There are many stock 993tt offered at reasonable prices whereas those upgraded to 450 hp cost substantially more. I'd like to understand if this is a consequence of the limited number of Porsche tuned engine or simply because performances of such an engine make the car really different in terms of pure performance.

    Thanks in advance
    Cheers
    SM
