EFI Pinto Turbo with megasquirt

Hello again , I've had a good look around the Skogenracing forum and i must say the quality and style of your cars are superb.
I have a Turbo pinto which i am converting to EFI, basic spec is low comp block , standard head , T3 turbo , Granada EFI, EDIS ignition and megasquirt v2.2 . I am hoping for around 150bhp on .5 bar boost.
Does anyone here have a similer spec engine running megasquirt ??
Can anyone tell me what size injecters i should use and do i need an aftermarket fuel presure regulater ??

Any help/advice/opinions would be great !!
