Part #: 800-1010
New set of 6 pistons with rings and pins for L20B engines. These are the later 280ZX pistons in a true flat top for higher compression in your l20B 4-cylinder. This is a set of 6 pistons, only way they come so you will have two extra pistons. Available in standard and .020" oversize 280ZX which is a L20B (85mm bore) will need to be bored 1mm oversize to use the stock 280ZX (86mm bore) piston. Get the .020" oversize for a L20B with a 86.5mm bore.
This piston should add approx 1 point of compression over the standard dish piston found in a stock L20B. This will vary depending on the cylinder head used.
