Side feed injectors, Is it a BOB v6 ?

You can fit Nissan RB25DET or SR20DET injectors. RB25's are in sets of 6.
The standard ones will give you up to about 330bhp, depends on fuel pressure.
Or you can use Subaru yellow injectors. They are said to be 550cc or 440cc depends on the year. but in sets of 4 so you wil need two sets.
Also all the above will need different injector plugs fitting. I got two subaru inlet manifolds complete with wiring to do mine.

Remember to swap the o-ring seal from the ford ones to the others.
