    Engine weights

    Please forgive me if this has been covered (yes, I tried to search the topic). With all the conversation about engine swaps, I was hoping someone could give the weights of varying complete engines (engine with induction...no transmission attached). I am specifically interested in the following, but I am sure other would appreciate other engine combinations being provided:

    2.2 liter engine with carbs or mfi

    3.0 liter engine w/ carbs (Webers or PMO's)

    3.2 liter with factory injection

    3.6 liter with varioram induction

    Thank you in advance,

    221 487 M64/20 993RS v-ram w/o ZMS 993 Tech Spec. book

    These are the #s to look at because they all use relatively similar flywheels. The later engines will be lightened considerably by the removeal of AC, cruise control, exhaust etc. I see ~100# difference between the lightest and heaviest in a worst case swap scenario. The 2.7 is a bit heavier than 2.4, mysteriously the weights are not in my copies of the Tech Spec books.

    I would have to add (or actually subtract) that difference between my 2.4S piston and (iron) cylinder set and the 90mm RS piston and (niki) cylinder set I replaced them with was about 10 pounds lighter...
