Ok! When should I replace my injectors and fuel pump? It's a 97 Tib and I haven’t replaced them at all. Also, I would like to replace my fuel pump with a larger pump. Would this benefit me at all if I’m running NA. I might put a NOS kit on it but, it wont be for another 6 months.

Help a brotha out.

Unless they're not working, you don't need to replace them. Ever.

If you're worried for some odd reason that one or two injectors are leaking, dripping or not spraying correctly, you can send them to RC Engineering. For like $100 grand total, they will test and flowbench the injectors just the way they are now... Then pressure and sonic clean them... Then re-test and flowbench them once they're finished.

Otherwise, fuel pumps and injectors really don't go bad unless they were cheap pieces to start with. A bigger pump is only necessary when you're making enough power that the stocker can't keep up -- ie somewhere over 200-220 horsepower on the pump.

 

Ok anyone else have some input???

 

Nope, he's right.

 

Injector malfunctioning, check resistence. Resistence OK, send for flow-testing. Flow testing OK, keep it. If either is screwed, replace with stock item.

If making monster horsepower, get the math textbok out. You're in for a few very long nights to get through this.

You're gonna need to upgrade if you go over the 225Bhp mark.
