Just joined, so excuse my noob!

Thinking about doing stage 1 kind of thing. I am aiming ultimately for ~300bhp, nothing too crazy, no forged things. My main aim is to focus on acceleration, not worried about top speed at all.Thinking hybrid TD04 then...
Full Decat or Sportscat exhaust from turbo back 2.5 or 3” bore
Ecutek Custom ECU recalibration (similar to PPP)
Twin boost set up for high/low power switchable in-car
Walbro 255 l/hr uprated fuel pump
K+N panel filter

and ultimately

Full Decat or Sportscat exhaust from turbo back 2.5 or 3” bore.
Decat uppipe Pre turbo
Walbro 255 l/hr uprated fuel pump
K+N panel filter
Ecutek Custom ECU recalibration
Twin boost set up for high/low power switchable in-car
AFP 04-H custom ported hybrid turbo
High Flow multi spray fuel injectors 550cc (380cc as std)
Uprated turbo to intercooler 'Y' pipe
NGK PFR 7B uprated spark plugs

My question is this - is it worth getting an AFP 04-H kinda turbo at stage 1 rather than a TD04 to avoid buying another turbo in 6 months (would stage 1 support it etc?) and assuming I do all the things, which one will have the least lag? Pure accelaration wanted here. Don't even care if it tops out at 70mph!
