terryo Posted May 8, 2011 Report 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

Crostek Posted May 21, 2011 Report 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: ? Quote
pinsx3 Posted June 7, 2011 Report Posted June 7, 2011 Got the pistons! but now I need valve springs and a camshaft! Any leads? Pete Quote
