redvalkyrie Posted December 9, 2016 Report Share Posted December 9, 2016 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, JP Quote Link to comment Share on other sites More sharing options...
filfrederick Posted December 10, 2016 Report Share Posted December 10, 2016 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. -Phil.
