Throttle body upgrade for 1987yj 2.5L

Is there a throttle body upgrade for my 1987 2.5L yj wrangler? I've read some posts where this swap was done. I appreciate any help.

Been curious about this too, know it works putting the 4.0 tb on 2.5l's work but wasnt sure if it worked for the 87-90s 2.5 with TBI opposed to the FI of the post 90 2.5l's

Yj's predate safety regulations.

For the 91-95 2.5 there is. Those years are multiport injection, so a 4.0 throttle body is an upgrade. Our 2.5, 87-90, are throttle body injection, one injector in the throttle body. I haven't found one yet.
