I suggest you give Ian Howell a ring - he has quite a few different injector choices for you to choose from

"If you are running OFAC you will be limited by injector size as the ECU will
not be able to control large flow injectors at idle properly and you will
end up washing the bores."

this will not be a problem on OFAC - dunno where he got that idea from

I sugest you hand the car over to Stu and let him work his magic
