The piston/bore is 105.5. They are a 12-1. The cylinder bolts in without any mods. The head does have to be clearenced.

I under stand that Pami has had these kits running in their races over there that is equal to our Baja races here.

I have never ran one of these kits on NOS or under boost ????

 

where can we buy the 105.5mm piston from? do we have to buy a set of 4?

 

JE makes the 105.5 pistons, they told me to go to Mr HP or TVI thats the only guys getting the Hi Compression Pistons custom made.

 

I had some of the 108mm made and had to buy 4 from JE. CP is going to start making some for me late Jan or early Feb. Depending on how custom of compression you want will depend on how many you have to buy. If it's comon probably just 1, if not ??????
