Alright. I've searched and read the fuel injector upgrade threads here on this forum and elsewhere, and I know it's a touchy topic. But, since I am going to have my fuel rail off anyway...

Are these http://m.ebay.com/itm/161331686944?nav=SEARCH going to be a good injector for my 01 5.2liter truck?

I know those are EV1 (Jetronic) and I have EV6 connectors (US Car) so I'll need an adapter. But other than that, those 19lb injectors should come out to about 23 on our dodge rails, which is about where I am now, but those are the four hole injectors which *should* be an improvement.

Will they work? Anyone else use these?

 

For my '98 5.2L I've been running Bosch #0280155784.
They're 4 port 22.3lb/hr@43.5psi (23.7@49psi) 12.5ohm.
They also need EV1/EV6 adapters.

Stock injectors for mine are Siemens 53030778 (EV1) 21.9lb/hr@43.5 PSI (23.2@49psi) 12ohm.

 

Personally, I wouldn't waste my money on used injectors... what do you think you're really going to get for $7.50ea?
Spend $25ea and get new/overhauled, and save on the labor of having to do the job again down the road.
