    I've had both an 8lb flywheel on my E36 M42 and now a 14 lb flywheel M20 flywheel on my E30 M42. Both were a good upgrade over the 27~28lb flywheel, but the difference between the 14-16lb and the aluminum 8 lb isn't that noticable.

      Oh come on. Any MAN would do a 8lb flywheel. Any MAN-GINA will do a 14lb flywheel. :)

        might want to research beyond the usual forum bullshit on that one bubba
        I had an Integra and a G20 as I've mentioned a couple times. They should have had good gas mileage. I usually got 19-21mpg around town with a decent amount of interstate travel. I just beat on it. You got to beat on it to get anywhere......

        I get about the same with M20 as I did my old four cylinders. And driving back the other night I realized I couldn't really live with / enjoy any less of a car. One of the reasons I don't want to go fuh raze on this and need a daily. Screw that. M20 daily.


        And having to go 91 instead of 87 is a big difference in gas costs. I've found that 4.10 on a M20 unchipped feels good, with pretty decent gas mileage with 87 octane costs! And with a 3% shorter tire, it's lots of fun.

        So really, think about what you really want? A fun to drive car with straight six feel, or a lighter more tossable car with a buzzy 4cyl?

          And any REAL MAN would do a grand-am spec 11lb assembly on an engine other than a M42 (unless it's fully built :twisted: )

            My bad...didn't realize you meant overall weight. I guess that wouldn't have mattered anyway because I didn't realize the cars were different in so many ways. Trunk tar? Good for Buffalo winters huh.

                i just filled up with 302 miles on the tank and put 13 gallons in my 318is. works out to be about 25 mpg but i beat the shit out of that tank. I imagine i could get well over 30 mpg on an all freeway trip

                      I weighed my lightened flywheel the other day and it's 7.7kg (~16.9 lbs)..
                      It's a stock M40 single mass fly wheel lightened about 2 years ago but I didn't get to weigh it before it went back onto the car..

                      Not to sure what's the original weight, I believe it's about 9kg (~ 20lbs)

                      if we were to go on further on this subject, better start a new thread... ;)

                      EDIT:
                      From Brendan Purcell's website, the stock weight for the M40 flywheel is 9.973... So it's that's the actual figure, that would mean I actually shaved off 2.2kgs off the flywheel..... 8)

                        Well I just tried another 318is and I must say it handle much much better. Transmission was smooth and the engine responded much quicker. I'm definatly buying one.
