No the loom is not the same because D16Z6 is OBD1 and your EK4 is OBD2 you will need to modify it a little bit or just change everything to OBD1 and yes you can use your old gearbox

yes it can be turboed. and you old box will fit but the ratios on the ek3 are very high but you'll already kno that
visit homemade turbo .com they have a guid to it and what turbo size to fit which engine codes mate also with it being forged you wanna check whether its not got high comp pistons cos if it hasd you WON'T be able to turbo it on those pistons you'll have to keep it n/a or get new pistons

all d-series boxes are interchangable apart from the DOCH d-series like the D16A9.

the D16Z6 and Y7 are the cloest ratio UK d-series box.

theres absolutly no reason you cant turbo higher compression ratio's, in a D-series i wouldnt drop below OE compression.

your also notice they tend to run custom length rods to bring the CR back up and deck the block.

a set of eagle rods and CP OE CR pistons will do you well.
