Vivid Racing Gear Select the year of your Subaru Forester XT:
If you’re diving into the world of Subaru builds, you’ve probably heard of GrimmSpeed. They’ve built a solid reputation for quality, and their EJ25 Head Gasket Sets are no exception. Seriously, if you’re looking for gaskets that won’t let you down, these are the ones to consider.
These gaskets are designed to handle everything from a simple engine refresh to a full-blown high-performance track setup. They’re built with a multi-layer steel (MLS) construction that’s tough as nails. The layers are engineered to give you an optimal seal when you torque them down, which is crucial for anyone pushing their engine hard. Plus, the top and bottom layers come with a Nitrile Rubberized Coating that helps seal up those non-critical areas, even if your mating surfaces aren’t perfectly smooth. It can handle a rough RA surface finish of up to 50 microinches without breaking a sweat.
What’s really cool is that GrimmSpeed didn’t just stop at one thickness. They know every build is unique, so they offer these gaskets in .78mm, 1.1mm, and 1.5mm thicknesses. This means you can fine-tune your setup to match your specific needs. And for those of you considering a little overbore work, the slightly oversized bore diameters let you go up to 0.5mm overbore without a hitch.
Now, if you’re planning on cranking up the power, these gaskets have enlarged center head bolt holes that fit up to 13mm head studs. That’s a popular upgrade for anyone looking to increase clamping force on those high-power builds. Trust me, you’ll want that extra security when the boost starts flowing.
Here’s a quick rundown of what you get:
- Sold as a set, fitting both single and dual AVCS applications.
- Die-cut multi-layer stainless steel construction for consistent quality, with a tight manufacturing tolerance of ±0.001”.
- Folded stopper layer to ensure a solid seal in the combustion chamber.
- Coated with a .25 micron Nitrile Rubber layer to minimize the risk of leaks, even on less-than-perfect surfaces.
- Compatible with bore sizes up to 100.0mm.
- Works with head studs up to 13mm (1/2”).
- Available in three thicknesses for whatever your build requires.
These gaskets are compatible with:
- Subaru STI (2004-2007)
- Subaru WRX (2008-2014)
- Subaru Forester XT (2004-2008)
So if you’re gearing up for a rebuild or just want to upgrade your current setup, the GrimmSpeed EJ25 Head Gasket Set is worth a serious look. They’ve got the quality and attention to detail that you’d expect from a brand that knows their stuff.
