uk tubos in a j-spec

I swapped for UK turbos without any issues and I can run higher boost (1.4 bar).

 

Yes, but it wouldn't have just been a direct swap, you'd need the UK manifolds, EGBV setup, downpipe, etc.

 

It's a waste of time in my experience, you loose that lovely mid range torque and only gain a small amount of high end power. The only way to do it properly is to uprate the jspec injectors, get a piggyback/standalone ECU, go TTC and have it mapped to run your desired boost. but then you're getting a fair way into the cost of the next level of mods... ;)
