MAP sensor / injector swap - what do ppl think?

I am trying to solve the fuel supply issues in my 7AFTE.
Initially i was going to do:
* larger fuel pump (4AGZE)
* Rising rate fuel pressure reg (malpassi 1.7:1)
* 2 extra injectors controlled by greddy rebic2 extra injector controller.
But now I am thinking I might try another suggestion I found on a US website:
* 4AGZE fuel pump
* Swap 1 bar MAP sensor for 2 bar MAP sensor (ex MR2 turbo)
* Install 320cc injectors
* Install rising rate fuel pressure reg (malpassi 1.7:1)
What are peoples thoughts on this? Apparently it works well, but i have not found anyone who has actually done it.
Thanks,
AL

Al,
What ECU are you using? 7AFE Standard needs to be programmed what ever way, swapping things is never a good way of doing it without make the ECU suit the mod's.
Anyway, The best options would be..
Fuel pumps: Bosch Motorsports or a standard Bosch from a 911 or Merc's (S500 or better), these will supply more than enough fuel and will accommidate for future mods. GZE or 7MGTE will also be fine, but the bosch we be the better way to go.
Injectors: 12A rotor, cheapest and biggest, GZE would do, but again, future mods.
Map Sensor: ??? Never tried
Pressure Reg: malpassi-Certainly

I think without buying an aftermarket ECU anything substantially larger will just be providing way too much fuel. If only i could get my fact computer re-programmed.. apparently it aint possible though.
