    Default Can you dumb-down an M20?

    Can you do away with the computer controlled stuff and still use an M20? I don't know how you would get around not having the computer to adjust the timing or not having the electronics to control the transmission, etc. Is this even possible with the M20?

    there are carburetor kits available for the M20. I looked into it when i had my E30.

    Default Dumb down the M20 and...

    you'll have to smart up the the owner.

    A triple Weber DCOE set up would take jetting, synchroing, dwell and no OBDC help.

    It's all old school plug pulls, sniffing exhaust and $$$$

    I like DME

    Early L-Jet M20s had a "regular" distributor as well - I'm sure you could combine it with a carb kit, for the ultimate in prehistoric fun.

    i am interested however in dumbing down the auto trans, so it acts only in "manual" mode like SMG, but with an auto gear system. i would love to be able to switch it to 5th the second i get on the highway, instead of waiting till the OFFRAMP!!!!... for it to shift there. and also shifting for hills in advance instead of waiting for the transmission to determine its already unable to do its job in the current gear.

    as for the M20, if you drop in some ultra light components from metric mechanic, new hot cams, and throw on megasquirt with individual coils, you will be absolutely amazed with the performance output of the M20.

    redline higher than an M3, with more power all the way there!
