Just weighed my mki.

Raptor13x · 06-21-2009, 08:40 PM

I just took my 2 to a scale!

2260lbs w/ 3/4 of a tank. That means it weighs about 2220lbs empty, perhaps slightly less.

Stats:
'85 MR2 w/20v blacktop swap, sunroof, power locks, power windows.

Weight reduction mods: no AC, no trunk carpet, no frunk plastic, lightweight exhaust, lightweight flywheel, 15" Kosei K1 racing wheels.

I'm fairly happy with 2220lbs, that's not too bad, though obviously less is more.

mr3 · 06-21-2009, 09:27 PM

Wow, I just looked at the papers from inspection and my car weighed in at 2650lbs. She's a heavy little critter. I guess its time to clean out the trunk with all my tools and other stuff.

Jackstand Queen · 06-22-2009, 10:15 PM

After removing nearly 250 lbs, a truck scale says mine weighs 2450.

I'd be deleriously happy if it weighed 2220.

Of course I have the heavy SC tranny axles, SC itself, PW, PDL, and T-tops.

Dumping 200 lbs. like say a hefty passenger, makes the car soooo much faster.

PearlJammzz · 06-22-2009, 10:22 PM

MK3's weight in at 2150...just FYI

Raptor13x · 06-22-2009, 10:59 PM

hmm, how do I dump 50lbs without stripping the interior or spending money? :P

Anything other than the stock exhaust including no exhaust

The stock exhaust coils around and weighs a ton. Mine goes straight back from the header and out the back of the car. It probably weighs 1/3 what the stock exhaust does.

Spare tire, jack, AC compressor and condenser, empty your windshield washer reservoir, and clean out the trash and loose change from under your seats.

Raptor13x · 06-23-2009, 01:59 PM

^ Way ahead of you on everything but the windshield washer reservoir.

Jackstand Queen · 06-23-2009, 04:45 PM

The heavy sound deadening mat on the interior side of the forward firewall.

The two 5 lb. slugs embedded in the body directly under the seats.

The two tow hooks in the front of the car.

The carbon canister in the engine bay.

Dump the oem seats. I installed some made in USA seats by Hunsaker at 25 lbs each. A weight savings of over 30 lbs.

No...if only I had a dollar for every time someone moaned about how many thousands of pounds the stock system weighed. it is NOT that heavy. The stock muffler is almost exactly 20 pounds, plus the cat and downpipe, which are another ten combined, maybe.

My car is 2400, full of gas. '85, sunroof, with power everything, functional A/C, cruise, spare tire, jack, etc.

Raptor13x · 06-27-2009, 07:26 PM

^ I guess where we differ is how much a "lot" of weight is. 30lbs is quite a bit of weight. I'd estimate my exhaust weighs 10lbs- downpipe, muffler, and all. Maybe a bit less. I'm a bit obsessive about saving weight- I basically take the Colin Chapman philosophy to car design.

And on that note, I ordered some lightweight lugnuts to replace the enormous stock ones I've been using. It's not a huge weight savings, but it is unsprung rotating mass.

kramerbuccs24 · 06-28-2009, 09:55 AM

2200 is great! what transmission are your running?

Raptor13x · 06-28-2009, 11:35 AM

C52

I wish I had some room for fiberglass work- I'd make a fiberglass sunroof, hood, trunklid, wing, and engine lid for it.

Ku-sama · 06-28-2009, 12:03 PM

remove the wing and side skirts. save 50lbs easy.

Raptor13x · 06-28-2009, 02:52 PM

^ More like 10lbs, and unfortunately I think the mki looks absolutely horrible without the stock bodykit. That, and the sideskirts are covering the huge rust holes in the body.

Jackstand Queen · 06-28-2009, 04:55 PM

If I had the money, etc. etc., I'd slap in a 6 speed tranny and use an aluminum flywheel.

The reduced rotational mass of the above mentioned setup vs. my E51 SC tranny, would make my car handle as good as an N.A., and make it drive like I'd removed well over 200 lbs. Though actually weight reduction would be closer to 100 lbs.

6 speed conversions aren't easy or cheap to do though.

Raptor13x · 06-28-2009, 06:10 PM

I have the aluminum flywheel, but I don't really see the point in a 6-speed. It strikes me as the "more is better" philosophy, that just ends up equaling more gear changes and no real gain in performance. The only point in having more gears is to keep the engine in the powerband- and if your engine has a good powerband, you can get away with 4 gears doing that, there's no reason to go for 5 or 6.
