2001 chevy cavi

i was just wondering if the fuel injectors from a 3400 sfi would fit in place of the stock 2200 ones

I don’t know the specific answer to your question, but you should be able to find out the technical information including physical parameters on the websites of the manufacturers. You may want to check out the fuel pressure/volume requirements while you’re there. And even compare the spray patterns.

You do know that you’ll have to reprogram your ECU?

In short, to get a drivable engine out of this will mean more than just screwing the old ones out and the new ones in. Let me suggest that you take the vehicle to a speed shop and let them work with you on adding more oomph to the engine.

No. RockAuto shows two different part numbers for the 2.2 liter and the 3.4 liter fuel injectors.


Tester, I think the OP was asking if they’d physically fit. I was trying to point out that there’s more to it than that. They’re entirely different animals…even if they do physically fit. You are of course correct, they’re not directly interchangeable.
