m20 flywheel hitting e34 oil pan

[luis.e30325es]

got mine to look exactly like that. cost $28 which isn't bad.

[luis.e30325es]

I had them take mine down to about 1-2mm above the ring gear.

i dont know if its me or just the pic, but did they shave around the center by the holes for the bolts?

[luis.e30325es]

Adrian is right, just that amount they took off did lighten the flywheel by about 3-4 lbs, which is a lot. A lot of people will have a large portion of the mass from the center out toward the edge of where I had the flywheel milled out too, taking out another substantial chunk of weight, but the shop I took it to wasn't really able to do it with their setup, and I didn't want to go searching all over for a shop that could. That degree of lightening is really unnecessary, anyway.

To have that material removed as well as a resurfacing (make sure you do that), cost me about $85, which is a little high, but not outrageous.

Yeah i'm just going to take it back to where they resurfaced the other side.
it cost about 35 bucks for resurfacing, which isn't bad being that they do commercial trucks with big flywheels.
i wonder how much they will charge me for this.

thanks for the help

I am definitely going to show that picture to my machinist.
thanks for the help guys, greatly appreciated.

I threw mine on the brake leathe, and just kept cutting. Worked out great.
I also have an extra I'm selling, thats been cut down in back and resurfaced in front, if anyone needs one.

When I did my swap using the G260, I had a local shop shave my flywheel like yours, but all the way down to the gears. Completely smooth around it, cost me $40 bucks. No rattle/vibration from it or anything.

I told the clutch shop to make it 12lbs, they did, it fit.

And with Redline MTL in the trans, I had no "rattle" from the lightweight flywheel, and an S52 still provided plenty of torque to get away from a light.

I meant to say resurface but my hands typed shave, brain fart.

Thanks for the reply, I was just gauging how much $ I should allot for that when the time comes (aka right now).

noob question, but how much did it run you, did they lighten yours as well aside from the shave?

Umm shaving all that metal off is lightening it?
