The below is only a guide and examples of prices off Ebay and for sale posts etc..

The best value for money way of going EFi is by using weber (Coworth) Management. The reason i say this and not FRST EFi for example is due to the amount that mapping costs. 1) Who will map FRST EEC4 2) How much! 3) Where in the country.

Weber can be mapped at every corner of the Uk and has some VERY good tuners to choose from. The cost for the map is around £100 - 200 Compare this when thinking of other systems.

Now the next issues is the parts costs.

FRST ECU £100 Chip (Off the shelf not even for your spec) £100
Cosworth £100 (Custom chip for your spec) £75

FRST LOOM £100
Cosworth £100

The sensors cost arpund the same for both systems. 3 bar map sensors on Ebay are £55 a FRST OFAC Map sensors is £45

Trigger items cost the same for both systems although with weber its costs a little extra due to the one extra sensor you will need. This is the cam sensor!..

So after all that the main differece between the two is the Thottle body which is bigger and better design on the cosworth and the extra cam sensor.

Both are just as easy to fit.
