This mk1 Escort is a beautiful car and the owner has done a great job!
For me (i have done the cosworth conversion!) it looks a hell of a lot easier than doing an sr conversion! everthing matches being ford and i would never put an sr20det in any of my cars!! EVER... sorry
once you have tasted cosworth power.... you wouldn't look at the Jap engines... if you were looking at a better engine you would be going something euro and well built [:u][:x)]

not something thrown together and requiring a full rebuild to belt out more power than a cossie stage 3 chip on a standard engine!
You say the main factor is cosworth parts and the prices if you do your research the parts are pretty much the same, and you can track them down easily!!. Just because Autobarn and Supercheap auto stock the parts doesnt make the sr20 better than a cossie... and a worked sr20det is not cheaper than a cossie!! talk it up as much as you like. if you want big power out of a sr20 you have to spend money! and lots of it too! just like a cosworth!
I know cosworth conversions have been done over and over... but there is a reason for that! the sr20 conversion has been done over and over because of convienience nothing else... IN MY opinion! Most people who do sr20 conversions always tell you... its because i couldnt find a cossie [:u][88] you all know it [:I]
I reckon if Phil added up the cost of his car Vs the Cost of this mk1 sr it would be very similar! (VERY EXPENSIVE!!!) BOTH CARS are a credit to the builders!Well done building a great car Phil!! and this mk1 escort is pretty awesome too...even if it has a sr20 in it

JUST MY OPINION!
