It's 1998 TJ has a 4 cyl auto in it. Some day I hope to put either a 4.0L or the old 4.2L with a fuel injection conversion, and a 5 speed.  I have put 4.88 gears in front and rear. I went with 4.88s, because I was going to put 35s on it but instead I kept the 33s, let's just say it is the first 4 banger that I've ever seen able to smoke a set of 33s. It has a 4" Pro Comp suspension lift and 2.5" exhaust running through a 40 series flowmaster, it sounds ok I guess.  It is still  an ongoing project, I'll never be able to finish this one.  Once I think that I'm done I will want to do something completely different.
