Default 03 Sti TD05 18G + 10 or 20% meth, Bigger injectors or FPR needed?

Hey guys,
I have an 03 STI type UK
I have just bought a second hand Andy Forrest TD05 18G that I will be fitting before mapping
I also have a perrin turbo intake pipe, Harvey up pipe, ported and wrapped headers, decat downpipe, K'n panel filter, walbro pump, 3 port boost solenoid and a cobra stainless cat back system
I think I have everything to get the best out of the 18g.
I also plan on running 10 or 20% methanol.
I know the standard Sti pink injectors would be ok enough without running methanol but taking into account that the methanol needs a much richer mix than normal petrol, would I at the very least want to put an adjustable fuel pressure regulator on or maybe even bigger injectors?
Anyone running a similar setup to this could maybe give me a bit of advice?
Cheers

Denis

My standard pinks maxed out at 350 odd bhp. That was with the standard fpr. Upgraded to id1000 and they was okay to mid 450s with a standard fpr.

650's would be adequate using 20% meth.

I'm running a td05 18g at the moment,making 380 on v power with 550's and fuelab fpr.
Not sure how meth would effect it though as not tried it yet.
