4.3 Injectors

[TheDirtyJeep401]

When you sit for awhile looking at an engine you say, " Can I put that on mine?" So hear I wondering if injectors from a Vortec 4.3 will fit a 2.5 (Or if there are other injector options) Thanks for the info in advance.

Ive been wondering this myself. I even began to look into it a little, but didnt get very far. we need to figure out if the TPS sweep voltages are the same or similar, and if the injector voltage is the same. The other issue is if the stock PCM can handle firing 2 injectors instead of one or if a relay system would work or be fast enough for it to work. I think injector pulsewidth is mostly controlled by the O2 sensor and temp sensors so for a two barrel pulsewidth should be much smaller than with a one barrel. I'm looking at rebuilding a spare 2.5 I have in the near future and want to do some performance upgrades and if I could find a manifold or modify the original to work something like this it would be awesome. Let me know if you figure anything out in the meantime! Good luck.
