I am in a similar position in terms of thinking of the 24 engine swap however I'm not a Tw*t and would like a bit of information of the conversion.

1) I'm in Australia and a lack of st24/st200 means finding one is like finding rocking horse poo and will cost about 3K.

2) I am happy to let my insurance company know as being in Aus my insurance is only 200 quid third party fire n theft.

3) I have already done the mk3 caliper upgrade (had to import calipers) and there are a few cars i could salvage a duratec 25 out of

4) There are other cars I could get ie a ford falcon xr6 turbo etc but i like the mondy.

If someone could give me a hand that would be appreciated - even a pm so this guy doesn't make a people killing machine would be fine by me
