Direct swap 2.5 1994 engine into an 89 TBI?

[89base]

My 89 2.5 TBI motor is tired yet still gets me down the road. Tired meaning; leak-down test no.1 cyl hear a lot of air through oil filler cap. a 50% leakage  ( 40/80). Other cylinders closer to 15% leakage. I have a chance to buy a motor from a 94 Wrangler under $600, 118k miles on it. With COVID 19, I have a lot of time to make the swap. I have heard the porting on the "newer" motors with multipoint injection are different than the old TBI inlet porting. In that case I would need to reuse my TBI head. Question: is the porting different enough that I would have to reuse the TBI head on the 94 block ?  Also understand the flywheel will need to be changed due to the ignition timing coming from the sequencing of slots.

The head porting is the same on the 2.5l, only real difference in the head is that that yours has an extra tapped hole for a temp sender, the spot is there on the later head but it's not drilled/tapped.

 

The long block is nearly identical but the front accessories are all a little different, you will want to swap everything from the timing cover on out so everything lines up correctly.

 

There is also a small difference in crank length so you may have to address that as well to get the crank pulley to line up right with your accessories.

 

I went with 95 parts onto my 89 long block but going the opposite way shouldn't be much different.
