My bare block 20B feels like it weighs as much as my 13B with heavy flywheel and intake manifold with carb, cast iron water pump, old style external fan blade alt. If you ran yours NA it would be a lot lighter.

I've got some weights of engine parts here. I posted this info on the club forum a while back, and here it is again:
13 2nd gen 13B rotor housing
14 12A eccentric shaft
9.5 13B rotor
5.5 '74 13B intake manifold
28.5 '73 RX-2 rear side housing (without stationary gear)
5? stationary gear
75.5 grand total
I also weighed just the twin turbo assembly, who's likeness can be seen here on Mike's site: http://www.2751engineering.com/20Bturbo_alone.jpg
38 stock twins
24 exhaust manifold and downpipe
62 grand total
This doesn't include anything else such as intake manifolding or turbo plumbing etc.
After my friend and I removed all that stuff, the engine no longer tilted to one side while sitting on a block of wood.
Goodfellafd3s, thanks man! Yes sir, I like it.

I'll be playing musical chairs with my cars tomorrow. Gotta get out to the garage and move some more stuff around to fit the GLC in there. I just wish I had that half bridgeport done and ready to go into my REPU. Oh well, the 20B install in the GLC is at the top of my list. If there's time before sevenstock, I'll start on the half bridge engine.

I chased the threads in the threaded starter bolt hole in the bellhousing yesterday because they were all trashed. 10x1.50. After I got done, I tossed the starter in the tranny so I could lower the car back on the ground. While getting some visuals of how far back the tranny will have to go with a wrench that was a little longer than 160mm as a guide, I discovered that the firewall is spot welded to the tranny tunnel in a very convenient spot. It's like 190 to 200mm into the tunnel. If I could drill the spot welds out, the edge in there would be a perfect termination point for moving the firewall back. Luckily, it doesn't seem to interfere with the heater core or anything else as far as I can tell. I'll need to remove the carpet and get down in there with a sawsall or something, but so far, it looks pretty easy. The only hard part will be the gas pedal because it wil get in the way of the starter. I'll need to reshape that part of the floor.

ah does the glc have the same "lip" on the firewall that the 1st gens have? if so i know exactly what you are taking about. i also know about your gas pedal issue, the r100 is the same way, you may be able to tweak/shorten the gas pedal to get enought clearance to hammer the floor. do you have an fc starter? they are the smallest
