I a bit against RRFPR because it strains fuel pump and is non-linear device where boost enrichment is governed by a spring and is superimposed over actual fuel MAP. I'm even more against adjustable FPR as they allow you to make complete EFI map obsolete with one turn of the pressure-adjusting screw.

I'm not aware how different companies engineer their conversions. But 3.2 engine is already EFI and you could do the conversion "the right way" with 400$ worth of MegaSquirt II and bigger injectors while keeping predictable stock 3 bar FPR in place. I understand that you can do light-boost conversion relatively simple and cheap with RRFPR's and such but I still believe that proper turbo conversion should use 3 bar stock FPR, properly sized injectors and WBO2-verified fuel map.
Thank you for your time,
