Engine weights

[Ducktail]

Hey, gang. Anyone know the weights of a '74 2.7 and an '83 3.0? The 3.0 has no cat and, in fact, would be wearing the SSIs from the 2.7 when it goes in. A Pano article suggested the 3.0 would be heavier enough to warrant a change in torsion bars ...

The 3.0 with all cis devices on it and full exhaust weighs in at 438 pounds i'm told.

My 2.7 bone stock weighed about 425.

Below are wts. with citation. I asked Bruce Anderson & Jerry Woods the same T-bar question (but based on a 3.2L engine w/carbs in a '73). BA didn't change from his book. So I'm sure you could go with that.

Here's a link to a thread that had a similar table:

Weight of the 911 2.0 6cyl.

[Bill Verburg]

Not similar, I researched and posted it

[Randy Webb]

Let me add some more trivia here -- a lot of the wt. is in the induction and exhaust systems (besides the crank & oil pump). But PAG used CAE for the 964 and esp. the 993 cranks (Aichle's engine book). So... if you put carbs on the engines, and SSI's -- the big engines (3.6L) may not be anywhere nearly as heavy as you might think. I've never weighed or torn down a 3.6L, but if anyone wants to ship me one, I'll get accurate wts. on all the components -- and will also see how well it runs in my '73 after a hotrodding -- at no charge!

[Ducktail]

So, Bill, as I read the charts (or try to, as it were), it looks like a '75-77 2.7 "S" (which is what my '74 Carrera has, except that '75 had airpumps) is between 441 lbs (Aichle) and 452 (actually weighed), and the '83 Euro 3.0 I'm putting in (930/10) is 419 lbs, w/SSIs & heat but w/o AC WEIGHED, and is also the weight stated by the "Tech Book." Do I have it straight?

Also, is there a way to actually weigh the engine when I get it out, short of taking it somewhere?

I have always put the engine on a set of corner balance scales to get a weight.

The 930/10 will be very similar to my old 930/02 Which was measured at ~419# dry, w/ exhaust, intake, flywheel etc., w/o AC.

The spec book also lists that 419# for the 930/10

Or put it in a truck or trailer, go to truck scales (free in Orygun) and eigh full & empty. Correct for whatever gas used if in truck. These scales are inspected regularly and will resolve to the nearest 20 lbs. (in Or.).
