i jus got a couple questions i wanna ask to sumone that has JUN3s or neone that knoes...
wenever the cam breaks...which side (intake or exhaust) does it usually break?
do i need to have high compression pistons or a "built" head in order to get the full potential of the JUN3s???

btw the jun3s are going to be installed on a gsr motor...i already know that i need to upgrade my valvetrain
any input will be helpfull...
thenx

 

cams breaking? your guess is as good as mine

Of course to get the FULL potential you WILL need a ported head and high compression

 

Erick from ERE was running Jun , it broke in 5 pieces , just forgot which was it do'h

 

Hehehe, my exhaust cam broke into 5 pieces too, I bent eight exhaust valves, but nothing else got damaged. The pistons got knicked, but are reusable
