Question About Rochester Injectors
The stunning engine bay photos gave me the bug to at least improve the appearance of my 1987 otherwise stock engine. I bought a complete 1987 TPI off of ebay to work on. It came with the original # 5235302 Rochester #22 injectors. I tested them and they are all 14.4 -14.5 when I test the pins. If I send them to Cruzin for clean and test match @$12 each will they be good to go, or, am I better off to buy the new aftermarket units which are only about $100 more. Your thoughts would be appreciated.

Unless you are absolutely sure about the condition of the injectors-
mileage, how the car ran with them etc, just go with a new set..
Do you even need new injectors or are you looking for something
to do?

How did you guess? Part of my new years resolution is to take apart a smooth running system on my vette to see if I can screw it up. No, I bought a tpi as mentioned and it came with these injectors that tested well on the ohm meter and, I thought if a professional clean and flow for $12 each would renew them I would send them in, and I'm sure that I would if my only other recourse was $500 for a new set. However, with the Ford/Bosch sets @$200 new I wanted to ask the question and you answered it. Thanks

Thanks for the reply Cusinartvette, I believe that you do know what you are talking about, and, with my 87 being 18 years old I know that I want to replace them if I have the top off for any reason. What I didn't understand was the possible role people who clean and flow test injectors played, thats why I asked the question. Do you recommend the Bosch/ford 22lb 0280150561-098 as a good troublefree replacement for a stock application? Regards

The reason to have the injectors flow tested and cleaned is to verify the flow rate and condition of the injectors. That is what people like Cruzin do.
From personal experience, having bought new injectors for one of my vehicles and also having had a set of injectors flow tested and cleaned for another vehicle, I'll take the used, flow tested and cleaned injectors over a new set. Just because a set of injectors are new doesn't mean they are a good set. They are a mass produced part and are rarely tested and matched up as sets.
If you decide to purchase new ones, ask the seller if the injectors have been flow tested and matched up as a set. Also ask for the flow sheet showing that they are. My bet is that they won't be unless you pay extra to have them matched.
Just my experience and $.02.
