Everyone knows how unreliable these F4R swaps are, especially when using an unlocked...

I think you have that back to front, a small turbine won't be restrictive (ie more pressure in the exhaust manifold than the inlet manifold) until it makes boost, so you can run the overlap at low boost and gain spool, but you will need to get rid of it on boost/high revs. Simply put, if...
it's all about the cams, SR20DET and F4RT have mild cams with almost no overlap so can live with the backpressure of a small turbine. The F4R has what is more like a race cam to a turbo engine so you have to size the turbo to suit, if you get it right it'll piss all over an SR20, get it wrong...
