97 base to 2002 3.2 swap questions
 

Hi everyone,

I am in the process of accumulating parts to do a 3.2 swap in my early 2.5 car. I happened upon a salvage S w/ a blown motor that I'm in the process of figuring out that engines next steps - but the real question I have is - I have a 97 with the DME that isn't re-programable - and I have a full 2002 car w/ E gas harness ect. I'm considering doing a car harness swap so I can just move over to E-Gas as well as not having to buy a whole new DME, Immobilizer ect setup. Is that a crazy prospect? Has anyone done a full e-gas swap? Or am I just giving myself a lot of work for unreasonable benefit.

Have you looked at the article on the Pelican forum? It goes into what is possible and what is not reasonably possible.

totally - I have checked it out - it essentially says "swap the DME - Very hard" which is fine. I'm just wondering if anyone has done it - and is swapping the whole car harness the best way - or is there a guide or something where someone has done something similar and if there is a better starting point. I've swapped a full harness before - it's a pain but it should give me some fun upgrades like the use of the Boxster S cluster, electronic frunk and trunk locking and e-gas. The ability to go to an even bigger engine in the future if I don't bore out this one as part of it's rebuild process.

I recommend to swap the complete wiring harness including all ecu's. Everything else will give you big headaches, because the ecu generations are completely different and have to talk to each other via can and interior bus.
