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

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.
