94 MPI 2.5 into 89 TBI 2.5 MJ

Not swapping out the renix TBI.

I know the distributor and all the sensors along with the flywheel have to be swapped. I'm obviously planning on using the renix manifolds and accessories

Is there any issues swapping all that stuff like there is when ya drop a 4.0 ho in place of a renix? Any sensors that need drilled or won't go in?

Never cared enough about a 2.5 before to swap in another good one. I always just swapped them out for 4.0s

Block and head are exactly the same. You'll have to use the 89 accessories and harmonic balancer.

Cool!

Flywheel same or different? (CPS tone ring)

This is a 98 going into an 88.

The crank snout will be shorter but your 89 dampener will go on, it will simply but up against the cam gear/oil slinger and stop. You'll notice the dampeners are different, one narrower than the other.

Yes, you'll need the 89 flywheel.

I'm using the 98 distributor, I just removed the sensor wire. Mechanically they are the same.

That's certainly not stock, lol!

These worth building? Got a buddy that built a bored/stroked one into a 3.0L but haven't been able to see it since it's been done
