Hello everyone,

Does anybody know, where to obtain JE high compression pistons (1,5mm overbore) ?

And another question : What are the possibilites of regrind or aftermarket camshafts ? - I know only about KENTcams..

Thank you for answers

(Winters are long - here in Czech Republic - So Im planning something... )

Thank you for answer : Mincehead. As always good and fast answer.

Ill try to contact KEDO.

Kedo definately has pistons. Kent does cams, but there are also Tornados and V2. See this link for specs:

Whau, 250€ per piston + 80€ head gasket... I expected little less


The V2 cams doesnt seems to be that "HOT" as I affraid they are, if I look at the graph from the tuning-fibel.de ... The max Torque is only 1k rpm higher, but there is still about 80Nm at 4k rpm (Yes I know, I cant compare engine to engine...)

Does anybody know something about KEDO cams ? - 30188 this number on www.KEDO.de

thank you.

I have the tornados, prob wrong set as i get a ton of tourque and mid but they´re top end...guess one need to set them with slotted sprocks or programable ecu. (wich i have so when changin to 900 motor soon mech will get all things right)
