Turbo upgrade

[Dazm100]

Currently running 210hp. On stock turbo. Thinking of going that extra bit. And modify the standard turbo. Or can u buy a off the shelf turbo?
Secondly I'm on the limit with standard injectors .if I was to go for upgrading the turbo. Would I be ok with just a fuel pressure reg?

The standard injectors cannot provide enough fuel for boost pressures of over 1 bar. The extra fuel cools the cylinders & without it, you are in danger of overheating certain components.
Some have used injectors with a capacity 50% larger than standard, but the ECU controls fuel digitally by opening by length of time.
The way around this is to use a 3 bar Manifold Absolute Pressure (MAP) sensor instead of the standard 2 bar one. Because this reads 1/3 lower, it compensates for the difference created by the higher capacity injectors.

The real question after you have done that... will it aid the drivability of the car?
