Im sure it will work if thats what you have to use, provided you make sure they get the valve releifs machined to match a 2T-G piston. But I am told its not a good idear, as the compression will probably be lower and the piston top is a weird shape. Do they have a raised part on one side of the piston only? For my motor, I got new 3T-C pistons from Repco, and ordered the 1mm oversize ones, and got the exhaust valve releif machined only.
