keith im not sayting its fook all but DIY is gonna be alot cheeper !!!!
not getting the 1.8 pully and drilled the block proper will be fook all in cost !!!, the cps holder is 3 quid from fords
you get a efi flywheel and efi loom from a orion,xr3i 90 spec or xr2i and pin swop 3 pins to convert it, buy a 3 bar mapsensor ( there 60 quid these days

) and then ya just need a addaptor plate as im not gonan be happy dremeling ya head for some reason
then buy the ofab ecu for 100 quid and then get it live mapped by grove and ya sorted
infact its ever cooler a idea as ya can use the top half of ya inlet and the bottom half of a efi inlet and then nobodys the wiser, then ya sell on the other junk to regain a bit of ya money (50 quid for a s1 metering head for example) and then ya also make a doubloe saving as the cars gonna be much much better on fuel too
dan payed for people to do it and as a result he got a job done that he wasnt fully capable of doing but he also went for cossie management too with is abit more involved too
it sounds alot harder than what it actually it, i would drill the block ( gotta be acurate and spot on btw) and fit the holder and flywheel just incase as the engine is already out
\
seriously i will drill the block for ya, ive done it already and still got me stencil for it too
