The guy in NZ that did the BL/BP EZ30 swap into a GC chassis used a Link G4+. Mind you, that car took him like 5 years lol.
The EZ30 from the BL/BP is more complicated due to having AVCS (& AVLS?) on the intake cam. Plus it has Drive By Wire Throttle and all that economy stuff, that you basically remap to be like a cable throttle.
I've thought about doing this swap myself, into a BH Legacy - kinda like @whitebait19's Lancaster, but with the BL/BP EZ30 and a 6 speed.
Seeing that beautiful car around town a fair bit doesn't help with the temptation too
