Wow, thanks. I was not expecting that feedback.

I had heard ST wasn't that much more expensive, is much easier to work on and fix once it's in, and has much higher peak performance, but I'd bet I wouldn't go very far with the stock fuel system; and to be honest, the greatest limitation I have today at speeds below 130kph is traction, not power. (And especially not peak power)

It was only that 'while I'm there, I may aswell upgrade' drive pushing me to aftermarkets - but if I have to go back in and re-do the job in a couple of years time, I'll be pissed.

I'm probably (much) better off just fixing the problem and replacing the turbo with the failed wastegate if need be. ... the good news is OEM turbos in good condition are actually pretty easy to come by.
