Hi all,
Well i am stuck with a 2.2l engine, i have done plenty of modifications but the limiting factor is starting to be the engine itself. A 2.2l has much more power than i need. I toyed with the idea of deactivating the cylinders but the balancing and infrequent power makes the engine vibrate and generally doesn't ride very well.

So short of changing the whole engine the only other thing i can think of is to destroke the pistons which i believe involves changing the crank shaft. It sounds like a very difficult job so it may not even be workable but has anyone ever done this. I am wondering if i can just get a crank shaft from another car which will work for my mazda 626 91. also how hard it is to change the crank shaft.

if anyone else has ever tried to get the engine itself more efficient i would be interested to hear what has been tried. I have already heard of changing the cam shaft, piston coatings and lean burn.

thanks
