TheyMadeMeDoIt Posted April 3, 2019 Share Posted April 3, 2019 Apparently my 2007 Gen 1 Cayman S has the DFI engine in it. I didn't think the DFI came into fruition until 2009? Link to comment Share on other sites More sharing options...
Craiglm68 Posted April 3, 2019 Share Posted April 3, 2019 Unless someone dropped a Gen 2 S lump into your Gen 1 body, you don't have DFI. Link to comment Share on other sites More sharing options...

Mavrik Posted April 3, 2019 Share Posted April 3, 2019 (edited) I agree with 👆 If it is direct fuel injection then it's defo an engine swap imo. Plenty of info on direct vs indirect injection on google etc. DFI is always a more expensive fuel delivery system... Fitted to Gen2 cars only, from 2009. Indeed, some other marques use what is called MPFI (multi-point fuel injection but the Gen1 S only had basic port (rail) injectors whereas the DFI system has the injectors directly mounted on the heads injecting the fuel straight into the combustion chamber...

TheyMadeMeDoIt Posted April 3, 2019 Author Share Posted April 3, 2019 I think he just meant the revised 3.2 engine with the different IMS Link to comment Share on other sites More sharing options...
GlosRich Posted April 3, 2019 Share Posted April 3, 2019 DFI is also just on the Cayman S from 2009, the Cayman is still indirect from 2009. Link to comment Share on other sites More sharing options...
SpannerMan Posted April 3, 2019 Share Posted April 3, 2019 Who has told you it's a DFI engine? It wouldn't be impossible but highly unlikely that a Gen1 had a DFi engine even as a replacement it's not a straightforward swap. Have you got much history with the car? 1 Link to comment Share on other sites More sharing options...
