Tomei Powered USA is proud to announce the release of their ARMS-M7760 Bolt-On Turbocharger for the EJ25!

Tomei has done some serious testing on this guy for quite some time now, and now, here at EDO Performance, we will be conducting our very own tests of this turbo on our own cars! Of course, the necessary steps to prepping the test vehicle has to be done. We have already selected our candidate and will be performing the pre-runs, installation, post-run, and tune all within this week!

You can count on yours truly to deliver the up-to-the-minute scoop and details of the installation. But hey, how about some more pictures of the beauty?

Things to look forward to:

- Side by Side comparison of a stock STi turbo to the Tomei ARMS M7760
- Dyno tune results of Tomei ARMS M7760 turbo (with supporting mods)
- Initial impressions from STi owner, Greg Wiist
- In car video
- TONS of pictures!

Needless to say, I’m going to have my hands full. Stay tuned!

Tomei’s newest addition to the ever so popular “Expreme” line- up is their equal length exhaust manifold for the EJ25! The 4-2-1 piping layout helps extract the absolute maximum power from your single scroll turbine. Exhaust gas pressure is best controlled with the equal length design, ensuring that power loss through the higher RPM is minimal.

Take this installation just as you would any other exhaust manifold installation. No additional oil pan is required for this installation as you’ll simply remove your stock manifold, and bolt on the Tomei Expreme Equal Length Exhaust Manifold! Of course, you might want to wrap the manifold to try and retain as much heat as you can in the manifold, and to avoid spreading the heat to the oil pan.

WRX Owners should not fear, as it IS possible to install this particular exhaust manifold on your vehicle, just as long as you have the right parts. Luckily for you all, we already did the work for you so we know exactly what you’ll need: an oil pan off of the EJ25. A quick phone call to Ferdie@SouthCoastPerformance and an oil pan was en route to the shop!

As you can see, the EJ20 Oil Pan is blocky and doesn’t have the clearance needed to fit the piping design of the equal length manifold. Purchasing and installing the oil pan from the EJ25 will quickly solve that issue as it has a “dent” to clear for the piping design.

Initial Start-Up

I started the STi right after the installation, things have already cooled down so I could technically call this a cold-start. I noticed that the exhaust note was a bit deeper than normal. As the car warmed up a bit, the car seemed to have quieted down back to “normal.” That lovely Subaru “boxer rumble” can still be heard, and fades away as you step on the gas to rev the engine. But that sound is replaced with a more refined, race-car like exhaust note.

Driving Impressions

After a quick drive around the block to make sure things were all good to go, you’ll quickly notice the torque is spread across the entire RPM range. Normally, you’ll feel it all at one shot, but now it starts and power does not fade. Now, this is all according to the famous “Butt-Dyno”, but the car will be tuned and the results will be posted so you all can get a more accurate gain.

Now personally, I don’t miss the rumble as much as I said I would. I still hear it. The feel of the car now makes up for the loss in sound. I have no complaints by it whatsoever!
