I had no issues up to 25psi and ran most of the time just above 20psi from about 2000-5000rpm
Boost is just half the issue, its flow you want to worry about, a big turbo will often flow more air at the same psi than a little one on these engines as it removes alot of the restriction.
I agree with piggy, these engines aren't exactly rev happy, you may find it goes alot better with a modern turbo. Piggys figures speak for themselves about the strength of these engines and I'm sure mine would of got there power wise without issue as at about 200bhp it felt remarkably untroubled
