Outer Limits 4x4 Board

I bought another suzi for my little sister and mum as a runabout. It needs a bit of attention in the motor department. One motor been cooked real bad blow back and another is ment to have blown head gasket but I have never heard running. I was gunna stick with the 1 litre but how much is a rebuild kit worth. ppl are telling me it would almost be cheaper to put a 1.3 in. Any one know any prices?

PS in runabout I mean 30" mudders and when know one is looking weld up back diff.

I can get engine rebuild kit for around $250

An asthmatic 1L pulling 30" mudders with welded diff!
Put a 1.3L in it at least.
