I am in the middle of building me a motor dont laugh but so far I have a 2.5 lt bored over 30 and am about halfway done with a major port job on my head, I would have never guessed there is about a 1/2 of extra metel on the intake ports that you can get rid of just to make it flush with the port, i am looking for a mid range cam so that i can make more power from the 2500-4000 I called crane cams and they kinda laughed said they have never heard of some one wanting to put a cam in 4cyl jeep but they could probally custom grind me one for some ensane price, and if seems no one make any high performance parts for the 91-95 yj but you can find some things but not a lot for the 97-03 tj anyone have any ideas thats not going to cost me over 250.00 by the time its done I dont want to have a grand on a 4cyl and so far the rebuild kit cost me almost 350.00
