If I ran a J crank with KZ 10.25-1 pistons/block and a J head. Would that put the compression where it needs to be Or is there another alternative
If you are talking about 10.25-1 street pistons--like wiesco or mtc ---the dome is not thick enough for a turbo application in my opinion
I now have my crank.
I need some advise on piston selection next. I have a Kawasaki Mark 2 crank, KZ
big block and a J-head which is shaved .030. I am trying to decide what
piston to use to achieve the correct compression for a turbo setup.
Considering the J-head will drop compression, would I still use the KZ 82mm
turbo piston or a higher compression piston and rely on the head to lower
the compression enough I assume thicker base gaskets come into play now too.

I ran MTC turbo flat tops at zero deck on my gas,efi,turbo,nitrous FB.ran the same pistons for over 4 yrs--sold it with them in it and he ran two more yrs on them.I ran both J and gpz heads.
I stay away from real big bores--hard to keep round--the sleeves are thinner and distort worse.1395 is as big as I would go personally--and if you did mess up something the 1395 can be bored to 1425 without resleeeving.I used MTC power ring arrangement and loved it---zero failure.APE wrist pins.
I used trick oil--pennzoil 10w 30 and trick plugs--NGK B9ESEdited by: funny1
Thanks, that is the way I'm going.[img]smileys/smiley14.gif[/img]
What is a typical price to bore a Kawy block and where is good to go Machine shops around me are stupid about bikes.
