With this dedication to extreme weight savings, I hope you're under 72kg or it's going to look very silly. :rofl:

A 6 feet 2" tall guy close to 40, weighing 72kg.. Now that would look stupid :D

The one with factory tint was 6,8xx kg, other two were ~0,3 and 0,4 kg lighter than that. Ofcourse, change to Lexan and save several kilos..

[Kershaw]

What were the weights of the other two rear windshields? How much did you actually save?

Keep it coming man. I love this build. The scale is my friend too.

This thing would be badass with an aluminum M52 with m54b30 rotating assembly... 240hp in that thing. Mmm.

That weighs more than my current setup, does not bolt on to a similarly nice close ratio box, and I can achieve my targets with the current lump.
If "more power" is the essence of BMW building, every E30 should have a turbo'd S70/2 :).
That said, I HAVE tested a 940kg E30 with ~240 hp M50 or 52 I forget. Anyway, it had slicks and all that racing stuff. YES it went like stink.

That's dedication to weight loss :P I wouldn't have thought about the weight differences of glasses.

That's just something I can do right now with zero cost. Applies to all parts that I have several of, in store. You'd be surprised at weight differences between two cast metal parts with the same part number.
Stuff starts adding up when you have a reaaally long list of small weight savings.

I had 3 rear screens in storage, put the lightest one to the car..

Repairing the wiring harness/deleting useless bits, adding/modding new stuff..

I bonded the windscreen on



Continued fiddling with the wiring

If I bolt on a part per day... How many parts are there to an E30?

Can't tell you the number of the parts but you have twelve weeks and there are 24 part categories. You need to finish at average of two categories per week. (Although you are well on the way in some categories)

Engine Electrical System
Fuel Preparation system
Fuel Supply
Radiator
Exhaust System

Rough measurement of cylinder wall thickness said the '66 block has a bit over millimeter more. Ofcourse it had 20 years worth of corrosion MORE than the E30 block when measured. Old block also is missing a couple waterway holes off the deck.

Pre '79 blocks are sought after items, in Finland atleast.

Battery will remain in engine bay due do cable weight. Moving it to the trunk would be 5-6 kilos of copper plus a significant amount of protection for the plus cable. Note that a longer main cable would alsohave to be thicker because of voltage loss (proportional to cable length)

I have no personal experience so Im just speaking on what Ive heard/ read

I quickly glanced through the thread, but Im curious why you used the 2002 M10 block and not a E30 block? Im pretty sure the E30 is lighter, though theres claims they arent as strong either.

No claims. It's a fact that e30 m10 blocks are not as strong as the old m10 blocks. The e30 ones crack easily from the head bolt threads. Even in stock engines.
