If you’re diving into the world of tuning your SR20DET, you know that the pistons are the heart of your engine. These bad boys take the combustion gas and turn it into the power that gets your car moving. But not just any piston will do; you need something that can handle the heat and pressure of a tuned engine. That’s where this set of Tomei forged pistons comes in.

First off, let’s talk about the build. These pistons are made using a high-strength forging method, which is a step up from the typical casting you’d find in most commercial vehicles. This means they’re lighter and more rigid, thanks to thinner walls that don’t compromise on strength. You’re looking at a piston weight of just 311.2 grams, which is pretty impressive for what you’re getting.

One of the cool things about these pistons is the exclusive forging material used. It’s designed specifically for these models, which minimizes excess material and avoids unnecessary machining that can weaken the structure. So, you can trust that these pistons will stand up to the demands of your engine.

The 3D profile is another highlight. With an oval barrel shape and calculated thermal expansion, these pistons move smoothly, reducing friction and improving performance. Plus, they’re compatible with 1mm oversized valves, which gives you some flexibility if you’re looking to push your engine even further.

And speaking of friction, the design includes thinner piston rings, which helps cut down on friction loss. That’s always a good thing when you’re trying to squeeze out every bit of power. You’ll also get the pins, clips, and rings included, all tailored for this setup, so you won’t be scrambling for parts when you’re ready to install.
