hes probably talking 0.040 not 0.4
0.040 is 0.5mm wich is the biggest u can get for aftermarket pistons like JE and still have plenty of sleeve

it wouldnt really raise the comp ratio but when you order up some pistons talk to the tech guys and they will set you straight on what you need to get.

Re: sohc boost question (nickromeo)
if you plan on boosting I would use 8:1. and as for boring I wouldn't bore too much, you need as much sleeve as possible when boosting, sure a blockguard will help with flexing a lot and is an alternative to using iron sleeves but if you boost way to much say good-bye to your block. Sleeves will only make your block virtually bulletproof

Incorrect.
0.020" is 0.5mm. You bored your block 0.040", which is 1mm over, or 76mm.
