If my 993 engine was out of the car I'd weight it, but it's lighter than stock because I've cut off or deleted a lot of auxiliary systems like power steering pump housing and gear, the AC compressor (and mounting bracket) the heater and intake vapor-evacuation blower motors, and even the cruise control. My flywheel/clutch/pressure plate assembly is light as well at ~19lbs total with the early push-type clutch and a PM 6.75-lb DME flywheel.
That said you have to add the weight of the large external oil cooling system that has to be added (no onboard cooler). In my case that means the -12 and -16AN lines and fittings, and two oil coolers with associated ductwork. I'd guess the 993 weighs at least 75 lbs more than the 2.7L before it, and there is an estimated additional 25 lbs of oil system... then there's the added 18 quarts of synthetic oil. The 915's weigh about 125 lbs. The mag cased versions are a little lighter, but not more than 10 lbs. I don't have a 930 in the shop to weigh, but a buddy in my neighborhood has a couple, one of which he uses in his McLaren reproduction build (from scratch BTW). I'll find out if he's weighed one of them and report back. Regardless, add at least 10 lbs for the 108mm CV's/axles more than modified 914 axles with 944 CVs. I don't remember the weight of a complete 914-4 axle/CV assembly. I'm still using a 914 transaxle with the 3.6 so I don't have the double whammy of a heavier engine/transaxle combo... yet. Since the extra weight is unavoidable, I've installed the fuel cell as far forward (in the front trunk) as possible and still accommodate the front cooler ducting, and the battery and fire bottle is up there as well. That makes the balance as close to my desired 50/50 as I can make it. Geez, I'd replace the headlight motors, but then I'd have to add weight to the front! Good luck |

Do you have to run one of those big oil catch tanks (Peterson) with a 3.6? |
