94-96 style injectors on 90-93 Q... INFORMATION/PICS

[qship96]

Has anyone replaced their O2 sensors as part of this operation? I didn't see any further references. Do you use O2 sensors from a 90-93 or 94-96?

One has nothing to do with the other....use the correct o2 sensor part number for your application. Try www.sparkplugs.com if you want to save a big bucket of cash.

Thanks for the information and tips.

Per thread recommendations -- here's the approach (items) I will be taking.
1. Set of 8 94-96 injectors
2. Set of 2 94-96 Fuel Rails
3. One 94-96 injector harness
4. Set of 90-93 fuel rail-to-runner seals (donuts) -- thus following thread recommendations.

In addition to the FI component upgrade, both O2 sensors will be replaced.

Also, clean the fuel tank, replace as many rubber fuel lines as possible, new fuel filter, and somehow run a fuel pressure check. I want to remove the possibility of contaminating the new injector setup by flushing tank and/or replacing accessible hoses while verifying the existing fuel pump can deliver the recommended pressure level.
