Converting from 2wd to 4x4

[twin turbo]

if you change pickuppipe you need the oilpump too...

Is it an Escos your converting back to 4x4 or a 2wd sierra that's going to 4x4?

If it's a. Escos it won't need tunnel mods as it was designed for 4x4, it's only when the shell was 2wd originally it will need modding.

i thought there was a bit around the gear box tunnel to allow the 4x4 gearbox?

Maybe there is then? As I did it the other way round 2wd from 4x4.

Yes Mark, very good point, best add 1sq metre 18 swg steel sheet, spot welder and grinder to the parts list

Also, I recall Paul Bailey used to offer this conversion (4 x 4 running gear & floor/tunnel mods) to customers with 3 door cossies. He did at least two that I know of.

Dont think so mate. I put 2wd stuff on to an escort Cossie before. Think the gear box cradle needed to be different, but the floors are pretty much the same.

early 4x4 used the power steering pump on the same side as the 2wd so it wouldn't need changing

[Adamski]

Yeah as long as you've not got a 3.9.

[Billy_RS]

Are the 7" and 7.5" rear diff the same ratio as standard?
