Exclamation 20b 15psi street port

Im looking on getting a 20b and running stock twins with a street port. I need around 550bhp and streetable (i have a very loose definition of this haha)
Do I need bigger injectors to run at 550horse? and would the stock computer compensate for this? (I know you need the stock computer to run the twins so how are people doing this?) Would stock apex seals work? if not i found 2mm racing apex seals which should do fine.

(I am not worried about smog because this is going in to a pre-1975 vehicle.)

you are going to need an aftermarket ecu. (which you need anyway unless you want to run the stock auto trans)

on top of that, you will need a medium size turbo and at least the exhaust ports opened up.
