First , Thanks for all the great info on here. I just got a 92' YJ with a 2.5 in it. The last owner said the compresion was down in all cylinders 20% and gave me a 2.5 with 55k on it but it's from a 01 TJ will this work? Thanks and i'm sure this won't be my last question. Also wanting to do some things to it, ( small lift,more HP) but on a limited budget.
