91 first gen 5 spd 4wd (jake brake)
 

wanting to put a jake brake or engine brake on it have any ideas for a kit or how to? also wanting to maybe upgrade tubos so trying to do it all in one any help?

The only option is an exhaust brake, no engine brakes available. you will also need to upgrade your exhaust valve spring to the 60# springs. If you want more information on the available exhaust brake & springs for your truck let me know.

thanks
