I am still very new to all of this and am reading through various articles on the web and have found a few things.

This thread was a massive help to me.

If you have a read through that you should learn a fair bit.

The most costly part of the conversion as said above will be the mapping and finding a suitable managment system. If i was to go down the route of a zetec turbo I would be looking into the MS1 system and that is mainly because I am familiar with their ignition mapping products which I have been very happy with.

Failing to fit a suitable management set up and have it mapped properly will leave all of your previously completed hard work pretty much useless.

There seems to be a lot of topics regards the zetec turbo conversion so get searching and reading and any questions you are still left with I am sure people will be happy to help.
