You've got lots of options out there, I personally wouldn't go the max out with fuel pressure you really want to keep the injectors within their spec range of use.
I think don't quote me as I'm still learning saxo parts, but the popular choice for you is upping to Clio sports 182's they are 330cc good for 200+ bhp
Once mapped in at their base pressure a fuel pressure reg will raise pressure accordingly to boost 1psi per 1psi.
