2.5 to 4.0 TBI swap question

I have a 95 YJ with a 2.5. I just picked up an entire intake setup(intake, tb, injectors, rail)from a 4.0 Cherokee. Has anyone swapped the injectors out too? Not sure if this possible, or even will be beneficial. I was also thinking about putting a tb spacer on with the 4.0 tb.

The 2.5 is a 4 cylinder. Im not sure why one would think an intake from a 6 cylinder would bolt on. You realize this will not work, right?

If you actually read what I wrote, I asked about the injectors. I know the intake will not fit. I am asking if the injectors would fit and provide anymore power. Thanks for the response.

I think it's a direct bolt on. I didn't use the the 4.0 tb on my 2.5, but I bought a modified tb that's slightly larger than the one on the 4.0. Wow what a power difference. I've heard from others than the 4.0 tb will work on the 2.5 With no modifications. You'll go from 52mm to about 60mm. Doesn't sound like much but you will find the power is noticeably better. Keep in mind you'll have to drive it several times before your ECU adjusts to the new air flow.

Interesting --------------

I was once a tree house.
I lived in a cake.
But I never saw the way - the orange slayed the rake --

Does that mean it will throw a check engine light, while adjusting?
