Want to make your Toyota 1GZ go real good?
You are going to need some compression, some valve clearance, and plenty of strength.
We stock these to suit up to a 13:1 compression ratio. (we can supply them in any ratio you like)
The key to running lots of compression, boost and timing is the combustion chamber shape. The dome on our 1GZ forged pistons are designed to fit tight up in to the combustion chamber of the cylinder head and squish band. This forces the fuel/air and flame into the centre of the chamber and piston, which allows us to control the flame front much more accurately.
Modern multi valve engines have really good combustion chamber shapes and valve angles, when we design our forged pistons we make sure to capitalize on it.
As an example, our own in-house built 1GZ's run these same pistons in our NA motors at 13:1, and in our boosted engine at 12.2:1 @ 12 psi (that's our 1,200hp, 10,000rpm engine) and we have never had a piston fail or melt.
*Includes 12x Forged 1GZ Pistons, 12x Ring sets (high quality Japanese rings), 12x wrist-pins, 24x lox.
*Does not include Connecting Rods, pistons will not work with OEM or OEM-length Conrods. These pistons are designed to work with out custom 138mm length forged Conrods.
*We can modify piston tops to suit any compression ratio, allow 1 week for machining. We are happy to talk through your project with you to help spec them to suit your fuel, cams, project.
