Better stick to the J series its bullet proof look awesome all painted and sound great even with 3 main bearing crank although later Js might have 5 mains but can be transplanted with J15, J16 or if you can get a mexican or central/south american J18.
A member on Ozdat is supercharging a J15 after removing his j13 look him up he has a wagon but cant find link atm on his build thread.
I would import a J18 for cheaper all up imported rather than rebuilding a J13 locally.
