Keep turbos under 15psi, and you shouldn't see any issues.
A nismo or tomei direct replacement pump isn't too pricey considering g it's direct fit, plug and play.
Check voltage to the fuel pump also, just had to put a direct feed wire and relay in mone due to pump seeing 10v.

If you don't have the budget, don't try and cover suspension, brakes and tyres (we spell it with a y) in one hit.
Focus on what needs to be done.
One thing at a time.
Before you know it, you'll have spent more than you purchased the car for.
