We have a 1995 Grand Cherokee Laredo with the 4.0l I6, its a jasper rebuilt engine that is sluggish for some reason, has about 80k on it. Looking into rebuilding as a stroker or swapping to a different engine. Looking to simply get a bit more kick out of it, hopefully not at too much of a loss in MPG. Also attempting to diagnose some transmission issues, the vehicle is fine in reverse etc however in drive it will essentially start in second, then shift into 3rd, sometimes will shift if first if you physically start it in 1 then go through the gears manually. Idle is about 200 rpm low and has a slight hesitation. Rear end is going bad as well. Looking for suggestions on the rebuild or swap, were considering converting to 2wd and manual as we use the vehicle on the highway, transport kids etc. Looking to mostly restore and do some light custom work i.e stereo, reapholstering the interior, possibility of fiberglass dash etc etc. budget roughly 10,000 for the entire build. any suggestions welcome (besides dumping it, minds made up to keep)
