how much power can u get with the cheap stroker?

Using an eta crank, super eta pistons, and an I head, you are basically building a super eta motor, so I would imaging the horsepower would be exactly the same as a super eta... :roll:

what car was the super eta motor in?

put the eta crank and rods from a 325e with the seta pistons

ive got a 2.7liter, not really all that powerful imo.

im looking to get an s50 or m30

But the stock eta compression is 9:1. Why do you want to lower it? Are you boosting it? Or are you putting it into a 2.5 block?

oh im sorry i have a 89 325i...so it has the 2.5 in it and i wanted to make it a stroker

has anyone done it? hows it run? is it a pretty good improvement?

i know that you can put the eta crank and rods from a 325e with the seta pistons from a 528e...and u get a compression ratio of 8.8 but i was wonder how much power gain will you get from that?
