muddymj Posted September 2, 2009 Author Share Posted September 2, 2009 i just read it only gives you 12hp gain of another site. and this :(The horsepower gained by swapping from TBI to MPI is not worth fooling over ) Quote Link to comment Share on other sites More sharing options...

Geonovast Posted September 2, 2009 Share Posted September 2, 2009 Is there anything else wrong with it, or just a shot motor? Quote Link to comment Share on other sites More sharing options...

Pete M Posted September 2, 2009 Share Posted September 2, 2009 Any 2.5L block from any year Jeep will work. (note that the older CJs had a "iron duke" 4banger and that is a completely different engine) Quote Link to comment Share on other sites More sharing options...
