GSC Power-Division Billet S3 Camshafts Non-AVCS for Subaru EJ205 WRX 280/280 Duration

GSC P-D 280/280 Billet S3 Camshafts for Subaru EJ-205

If you're diving into the world of high-performance Subaru builds, you've probably heard about the GSC Power-Division billet S3 camshafts. These bad boys are tailored for the EJ205 engine found in the WRX Version 5 and 6, and let me tell you, theyre not just your average camshafts. Designed to unleash some serious horsepower, we're talking about a potential of 700 WHP and beyond. But hold on; to truly harness that power, you need to be ready with a few upgrades.

First off, let's get real. You can't just slap these cams in a stock engine and expect fireworks. A built motor is a must. Think of it as the backbone for your build. Pair it with a well-ported head and a solid engine management system, and you're on your way to something special. While you can technically run stock valve springs, I highly recommend investing in some upgraded beehive springs. Theyll help keep everything in check, especially as you push those RPMs.

Installation Insights

Now, when it comes to installing these camshafts, a bit of finesse is required. Youll notice in the pictures that the long nose indicates the left side, while the short nose is for the right. Just a little heads-up: due to the size of the lobes, you might need to file down the head castings slightly for clearance. This isnt a huge deal, but its worth checking during installation to avoid any headaches later on.

Also, remember to break these in properly. Running high zinc oil is crucial for flat tappet engines, so dont skip this step. And if youre not a seasoned technician, its best to hand this job over to someone who knows their way around a Subaru. Trust me, you want this done right.

Specifications That Matter

Lets dig into the specs a bit. The intake side boasts an advertised duration of 280 degrees and a duration at 0.040 of 241 degrees, with a peak lift of 11.20mm and a centerline of 110 degrees. On the exhaust side, youre looking at the same advertised duration of 280 degrees, a duration at 0.040 of 240 degrees, and again, a peak lift of 11.20mm, but with a centerline of 115 degrees. These numbers arent just for showthey're engineered to maximize your engines efficiency and power delivery.

Oh, and just a quick note: these camshafts are non-AVCS, so keep that in mind if youre planning your setup. Overall, if youre serious about pushing your Subaru to its limits, the GSC P-D 280/280 Billet S3 Camshafts are a fantastic choice. Theyre built for enthusiasts who want to take their ride to the next level, and with the right setup, youll feel the difference in every rev.
