oh and the 1800 is only 1769cc unlike the zetec 1796cc

so youre only talking 172cc difference - say 10% --- so if everything was kept exactly the same -- youd be talking 10bhp more - for equivalent power per litre...

knock off your low comp ratio that you'll get..... knock off the lower revs due to the undersquare bore/stroke, lose efficiencies with short rods and higher stresses --- and if it makes 10bhp more than your standard xr2 ill be amazed!!!

ferriday engineering do a 1800cvh based on this block - but its not a simple bolt it all together hope for the best kinda jobby - i.e. it has zetec pistons etc
