Big bore 103.6mm 996/997.1TT piston-cylinder set

Have us add these awesome 103.6mm pistons and liners to your project, or grab some outright for your own project.

Using the highest quality Nikasil Coated Capricorn steel liners we could find, we’ve achieved durability and reliability rivaling the oem’s while also increasing the power and torque of your project substantially.   CP pistons using 2618 alloys and DLC coated wrist pins are also run with this setup.

Gt3 valve pockets and a perfect range of compression ratio depending on stroke can make these simply amazing on the street or track.

With stock 76.4 stroke, these are 3.9L.   Throw our 80.4 crank in with these for an amazing 4.1L!  That’s a full 500cc greater than the stock 3.6L engine!

These definitely fit the “no replacement for displacement” saying.

Available with reliefs for up to 12mm or 1/2″ head studs and either o-ringed tops or plain.
