top of my head says no mate if you're talking cossie pistons out of a cossie engine  If you are not increasing the bhp of the car, i think the pistons are ok, at a push maybe some ARP Conrod Bolts but the standard crank can handle 500bhp y0  If you are turboing, calibra turbo pistons are good, but require overboring and a 2.1 turbo result etc etc yada yada and is expensive |

going technical on me now  also is a 4-2-1 manifold better than a 4-1 |

Course it is! All the exhaust gasses won't be meeting in 1 point at the same time with a 4-2-1, it's kind of filtered into the single pipe rather than being forced into it. If ya get me! As for the pistons, no idea, all that knowledge has been long since lost in my ageing mind!

well the YB is really a 20 year old design engine at least, so i doubt it mate  and not all the knowledge has gone yet Des

I've been meaning to get remote start fitted for a while now, but there's always something else to be spending money on But I'd never thought about it being a homing device aswell, nice one

in short the answer to your question is no. the YB runs the same size pistons as a Pinto. hardly suprising as its the same block essentially unless its the thicker walled 200. anyways. the pistons in that are 90 mm (or thereabouts). the pistons in a 2.0 zetec are 85 with 86.5 being an acceptable size for an overbore. you can get performance pistons for a zetec. altho it would at this point be worth mentioning that the gudgeon pins are a bit of an arse to get out as they are interference fit in the rod and float on the piston. depending on the age of your engine there are 2 sizes of pin. 19mm and 13/16ths. (21mm in new money) and i have no idea of the pin size on a YB piston. but the essence of it is no they wont fit. the 4-1 is better for top end horsepower youll lose a bit of lower end...the 4-2-1 will sacrifice a small amount of top end for some more useable grunt lower down besides. cosworths are forced induction. why would you want a lower compression ratio in an N/A engine? jam |

just wondered and forgot about the comression ratio
