So far I’m looking at

an st170 engine or 2.0 Zetec blacktop

a different sump to clear the crossmember in the mk3.
a shorter sump pickup that fits the sump (can anyone point me to where I could find this stuff or the correct name?)

an ib5 mk1 escort gearbox that will fit the engine (will this fit the st170?)

a zetec engine mount (how many?)

and probs a bunch of other stuff I’ve missed like upgraded brakes and wiring, fuel pump? but as usual any suggestion/links/ advice is greatly appreciated. Many of the build projects on here are pretty detailed and would love some simplified versions.
