I am in the middle of a rebuild.
I am doing the 3.8 to 4.2 swap
2002 V6 Cont. Windsor intake, 70 mm throttle body, dual exhaust, cold air intake, factory 3.73 gears.
My question is while everything is apart and the fuel injectors have 200 K miles should I replace them?
I am not trying to build a street rod, this is still a daily driver, but why not have a little extra if you can.
I am not sure of factory pressure for fuel injectors.I think it is 19 lbs.
If you could suggest which way to go it would be appreciated.
Stay with factory and factory pressure or upgrade slightly?
Replace or do not replace?
Thanks again, I have found lots of useful information on here.

IMO, replace with stock injectors, no reason for more pressure if you are not supercharging.

agreed, stock injectors unless you go FI.

You can get flow matched injectors though. That's where they match all six injectors to have a within 3%, 2%, or even 1% flow rating between themselves. Makes for more consistent power. If you go that route, make certain they provide a certificate of calibration with the injectors, if they don't, don't pay extra for their 'matched' injectors as they could just be selling you the idea.

Anytime I've replaced injectors, I always go the matched flow route. Costs a few bucks extra but may as well for piece of mind.

Thanks guys for the input. I really like the balance fuel injectors I will see who offers them.
