I think the Ford 2.0L I-4 EcoBoost might be a good E30 engine

I wouldn't think it'd be too hard. The rear-wheel-drive Ford Falcon in Australia uses it. :)

Seems like the small lightweight turbo 4-cylinder from the Ford Focus ST would be a good candidate for an E30 swap. Ford Racing sells a crate engine and also an ECU and wiring kit . It looks like a salvage motor pulled from a 2013-14 ST runs about $3k. Mated up to a 6-speed I think it'd be pretty awesome.

I'd agree. depending on the complexity of adapting it to rwd it would be a monster. Few local guys have those ST's wrapped up over 300whp.
