terryo Posted May 8, 2011 Report Share Posted May 8, 2011 (edited) i can help you with cast pistons via my work. i have an engine shop with lots of Toyota experience. pm me if interested. There are still plenty of suppliers of reasonable K pistons, but they all are cast. the 4AG forgies definitely wont go into a 3K removing the gudgeon bush is an old 4AG trick to use pistons with 20mm pins in a rod designed for 18mm. these days, if you use diamond hard coated pins ($60 ea), they last oK. without the hard pins, expect about 1 season before replacing the pins FYI, the ACL piston factory in australia has closed and most of the tooling has gone offshore. I doubt we will see much old stuff from them ever again. Edited May 8, 2011 by terryo Quote Link to comment Share on other sites More sharing options...

Crostek Posted May 21, 2011 Report Share Posted May 21, 2011 I talked to venolia, wasn't sure i wanted to spend the coin and wait 3 weeks.... Special rods are big bucks for an old school set-up. OK for a teardown after every race, not for a motor that you want to teardown every 4-5 years. I'm just vintage racing. My 3k runs 1GGZE rods, and have 20mm pin the 1ggte are 19mm pin and could be machine out and re-bushed as well. Do you want to sell your pistons :rolls: ?
