From what I've seen posted, I reckon up to 320-330 on a TMIC, maybe 10-20 more on a FMIC. Probably FMIC produces colder air more consistently allowing more boost or timing to be run.

TBH you're engine spec. looks worth more than a VF28 is able to provide.

If you're still on the original RB5 TMIC it's a bit small for the job.

No flame suit needed from me mate, I totally agree with you. But having to wait a little before my next spend on the car. Going to go for an APS front mount and definitley changing the turbo in future

 

I've seen 320 out of mine. That's on a decatted sti5.

Defo needs upgrading to go any further.
