What engines use the 7.8 DME ?
As most of you know, I’m trying to source a new motor for my car. It’s a 2004 Boxster S so it uses the motronics 7.8. I know that I can plug in a 3.6 from certain years of the Carrera by adding a few wires and a 996 tune. I’m trying to make a list of possible engines that use this DME and what electronic modifications would be necessary to make everything play nice together. An anyone help me out here?
Cheers, James :) |
I suppose you've seen this Pelican article which has info on the 2003-2004 cars? Before I decided to have my shop rebuild my 2003 S engine, they had a totaled 987 Cayman S with a crate 997 3.8 engine that was being parted out. They said it would work in my car with the ECU, but I passed as the total cost was way more than I wanted to spend. But they said it would work, which is consistent with the article. Good luck, I feel your pain!

986:
M96 2.7 228 HP M96 3.2 260 HP M96 3.2 266 HP 987: M96 3.2 280 HP 996: M96 3.6 (320 HP) from 2002 on with electronic accelerator pedal. M96 3.6 (X51) from 2002 on; X51. Might not fit easily in 986 engine compartment because of height M96/97 3.8 (381 HP) from 2003-2004. Might not fit easily in 986 engine compartment because of height The 996 M96 Turbo engines from around 2002 on also work with a DME 7.8 but there will be some problems to get them into a 986. The DME needs to be flashed to the engine and car. |
Cool! Thank you for this list. I believe that my add-ons such as headers and deep sump from my 3.2 3-chain should fit okay on a 3.6 as they are essentially the same motor?

I hope you get a good engine. I've been following your threads as my own 2003 S engine failed in July after I drove up to Mt. Tremblant from NJ and before I got on the track! I struggled with what to do with my own car for a while. I finally decided to have my shop rebuild the engine, and the case was sent out to LN for 3.6 Nickies. LN has completed the machining but its now in line at the platers for the new liners to be plated so that LN can do the final polishing and precision finishing. Once the case comes back from LN it shouldn't take too long, but the wait has been hell!

Then after I started on the rebuild path I saw that Porsche dealer parts departments were clearing out their rebuilt M96 engines. Still pricey but a known quantity. |
Top off your build with a set of these.

Id skip the rods and just install a set of arp bolts in your stock rods. The rods dont break, the bolts fail or the bearing spins causing the broken rod

You can certainly try to adjust bearing clearance, but I'd say thats less of an issue. |
I'm probably wrong here but my last experience with stock powdered metal cracked cap rods was the rod bolts cannot be replaced because they are integral to the cap alignment. Has that changed?

Of course, being there considering the Carrillo rods would be a 'huge step up' 😁 Honestly, originally I budget on my engine rebuilt (using LN Nickies) a set of Carrillo's along with a head work from Hoffman Automotive However, it is difficult to draw the line, that is the reason I said that you could 'only replace' the conrod bolts with ARP's to keep te cost down.. . |
