im having a new crank put in as mine is knackered as was contemplating some new injectors but are they worth fitting with the setup i have ie will i gain much more out of the car with these fitted, im sure the bloke repairing the car said hes found an sti crank so will that make any difference on its own to, plus the timing belt was out by 1 notch or tooth not sure what it is so is that another concern to worry about

i have

Why are you using Dawes device when the Apexi is controlling boost at 19 psi?

Crank change won't affect power, if the STi crank is any better than the one you replace ( you don't say what car / year your's is ) then maybe it's stronger and so safer to higher power / rev limit?
Probably best to uprate the bearings and change piston rings maybe ( even go to STi pistons ) while engine is in pieces for stronger engine all round with best efficiency.

The new 440 injectors would mean a remap to the Apexi PFC to sort fueling out, assuming you had 380's in before. Then, if the extra fuel flow is needed, more power could be had - if more fuel was not needed, then you have head room for future improvements. Or ignore the 440's if your current running duty is 80% or less injector duty cycle and save the money for something else.

Timing belt - hmmm some one set it up wrong, car won't give it's best if cam timing is out, get it set right.

apexi needs a boost controller be it dawes or electronic you will be fine with 440 injectors and raised fuel pressure
