    2.7i flywheel/clutch questions

    just got a 1986 325 (2.7 eta) for free yesterday with the intention of building the budget low compression 2.7i stroker and a home brew 50 to 60 trim turbo for, autox, drift and other fun events. this is a budget build and i fully understand that i may not be competitive in many series.

    the car does not spark, the crank postion sensors have been replaced and i will be replacing the flywheel shortly (bmw tech said most likely the timing positioners dropped off the flywheel when the car hit a curb and died).

    i fully understand that a stock clutch would hold 2.7i power perfectly fine, but i need to know if i can use a 325i clutch with the eta flywheel as the car will have 220-240 hp (goals) down the road with the turbo. thanks alot for your help guys.

    btw car is rotted to shit and it's all getting swapped into a clean shell (but dying m42 318i) will be posting pictures shortly in the for sale classifieds if anyone needs parts. very clean interior mostly.

        Use an I flywheel, they're like half the weight

          what did you do to deal with the crank shaft indicator that eta's have on the flywheel?

              correct me if i am wrong (very new to this), but i was under the impression that there weren't many heavy duty after market clutches for the eta. hence the question of whether i can use a 2.5 clutch, considering the possibility of forced induction and low mid 200 hp numbers in a few months.
