Yep. It's on the list of parts to buy. What one did you go with? The VAC ones are pretty expensive. I'm considering this one http://www.r-mracing.com/catalog/pro...products_id/33

Although I really am considering making my own seeing as this is all any place selling adjustable cam gears is doing...



I've heard bad things about the cheap ebay gears with the tooth patterns being off causing belts not to fit.

Not too much to update about. I'm supposed to be picking up a flywheel tonight and will hopefully get into the shop tomorrow night to lighten it. Then I can get my crank balanced with the flywheel and get to assembling the bottom end. Also, a friend of a friend might be powder coating the block for me (depending on what he says it will cost).

Today at lunch I measured up my cam gear and drew this. It shouldn't be too hard to make with a mill and a dividing head.

let me know where you get your flywheel machined and how the price/quality is. I'm gonna need to get mine done for my m52 swap.

I'm going to be doing the lightening myself at a friend's shop. I'm not sure if they can do it, but give Heimpel Automotive a call. They decked my block and head and I was satisfied with both the price and the quality of work. If they say they'll send it out to be done they are more than likely sending it to Forest and Forest Racing. They are located in Ayr. That's the shop where my crank is getting balanced. I haven't gone to pick it up yet so I can't comment on their work but the gentleman I spoke with at the shop was friendly and knowledgeable.

Quick update. I picked up a flywheel last night. It weighed in @19lbs (as expected). I am going to be lightening it this evening and will update with the after weight and pics tomorrow.

Just a side note. The shop I picked up the flywheel from is located in Mississauga and is called KTM Motorworks. It's a one man shop and the guy who runs it is an E30 nut, he's got a built Turbo M20 in the shop that he told me put down 500hp on pump gas last year. He told me he's planning on getting a better turbo and some race gas this year for some serious power. Overall he was a nice guy to deal with.

Flywheel updates:

Started by turning down the step



Then I cut away some of the middle



Finished result



I just weighed it and it came in at 15lbs. This was my first attempt at lightening a flywheel so I was conservative with how much material I removed. I definitely know where the other pounds can be removed next time around. However for now I'm happy with a 21% weight reduction.

The flywheel and pressure plate are going to get balanced with the crank this evening.

You work at Linamar, just make friends with the guys who work on the manual mills and lathes if you have them at your shop

The 4 cylinders actually have pretty heavy flywheels to help them get off the line smoothly without having to rev them too high. A lot of the M42 guys do lightened M20 flyweel swaps.
