Precision 1/2jz machine work. When honing the cylinder block, it is important to use a torque plate to simulate correct cylinder bore shape as they can have a slight variance when not having a cylinder head torqued in place. Using this we can make sure each cylinder is precise to .00X~ .000X measurement. Come see us today for all your race engine needs! 111 N church st Greensboro 27401
