You don't need either of those. Turbo'ing either an "eta" or an "i" motor has been done a thousand times. You need at a minimum a manifold, turbo, downpipe, exhaust work, fuel management, a wideband, oil feed lines and oil drain. Also plan on an intercooler, plumbing lines, air intake filter and a lot of learning and manual labour.

Or, just throw money at it and take it to a shop.

Optionally, there are lots of things to do. Low compression, o-ring the head or block, metric blue bolts, head studs, external wastegate, spark control, EGT monitoring, fuel and spark control via standalone, intercooling upgrades, clutch, traction improvement (tires), etc.
