RRFPR or 5th injector?

[volvero]

I have a b230 intake manifold with a CSI injector and fuel rail for free. My idea is to run 12-13 psi on the weak '87 block. Would it be a good idea to use this 5th injector or is better to use a RRFPR? What is the best way to control this injector, pressure switch or the TPS?

Thanks.

Better to use a larger fpr. A 4 bar works well. Or brown tops. You should search the article section... A great write up on how to install them on your car.

At 11 psi I'm still on the rich side, Its just to be safe.
