It's the off season here in the wonderful state of Oklahoma, USA. That means bitter cold and prepping for spring.

 

I'm considering boring my block and fitting over-sized forged pistons. The only place I have found that make pistons for the 4K is Kameari and those are 88,000 yen or about $770 US. They're also 79mm which seems like a stretch in the 4K block.

 

Is there another company that makes over-sized forged pistons for a 4K?

 

Thanks and happy holidays,

the usual piston places like wiesco or arias will make a set for you and not at a huge cost, just fill out the form or give them a call and they can sort it out for you. should be easy from the states.

 

79mm wont be a problem for 90% of blocks, just have the machinist sonic tested before boring to see if they need to move the centerline a bit to get in the center of the casting.
