The SPi tank should be good for more than 12psi boost.

What you have to remember is that the SPi system runs at 15 psi to start, with 30psi right at the top of its range. So with the carb running at 3psi and boost at 15psi, you wont have any problems.

Problems arise when, like me you fit a multipoint injection system running at 45 psi and 15psi boost. I,ve even had to upgrade the standard MPi pump*oh well*

Is it A-Series only? I think it should be...
So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...
