Default What turbo came on a ver5/6 sti? What should I upgrade to?

I have a complete version 5 swap. It has a vf28 turbo on it, which I believe is orriginal. NorthUrsalia has a version 6 sti engine and his has a vf30. I am wondering if both of these turbos are orrriginal.
Did a ver5 come with a vf28, & a ver6 came vf30?

Also I am looking to get more power out of my ver5 what turbo should I go with and who should I have tune it. (has anyone done any upgrades/tuning to an older sti?)

F1 dyno said they couldnt tune it!
Franz isnt @ KTR anymore!
TDC tuning never returned my email!
Lachute tuning never returned my email!

I know Lachute can do JDM ECU's and I think the UTEC might work but im really not sure.

Yes those were the OEM turbos for those engines. It depends on how much power you want out of the engine and what your goals are. For quicker spool and decent power perhaps a variant of the 16g or 18g. And for more up top a 20g or even gt30 or FP green
