An important part of getting the most power out of the EJ255 in the Forester STI is improving exhaust flow. The factory catalytic converter (cat) is quite a restriction on flow and it being right at the outlet of the turbo will really reduce the speed the exhaust gas can flow through the exhaust turbine […]

Forester STI – Cold Air Feed
The factory inlet to the air box draws air from just behind the headlight down into a Y piece with a large air box underneath then back up into the filter box. The STI fog light covers have a useful grille section on them though that I thought could be used as a nice cold […]
Forester STI – Fitting Longer Wheel Studs
Having trial fitted the Rota Grid Drift wheels I was happy I wanted to fit them properly. The first thing to do was to fit some longer studs on the front due to needing 5mm spacers for the wheels to clear the Brembo calipers. I boought a set of these Hardrace studs. Time to get […]
Forester STI – Rota Grid Drift Wheels
The wheels that were on the Forester when I bought it are proper GC-010E Prodrive/Bridgestone branded forged items made in the Rays factory in Japan. They’re quite a desirable wheel, look good and are about as light as a set of 18’s are going to get so they drive very well. Me being me though, […]
Forester STI – Front Anti Roll / Sway Bar Whiteline Drop Links
I bought these drop links when I bought all the Whiteline parts for the rear anti roll bar upgrade. All info on that here. These are the same Whiteline KLC32 drop links as I used on the rear as they are also the correct part to replace the front drop links on the Forester. They […]
Forester STI – Wales Road Trip and EVO Triangle
We thought we should do a road trip in the Forester. Wales is somehwere we hadn’t really driven round much before plus it’s where the famous ‘EVO Triangle’ is, so we figured we’d better go stay there for a week and check it out. After a good clean the day before, we packed our stuff […]
Forester STI – Pre Road Trip Clean and Detail
We planned a week away for a bit of driving on some nice roads but before we could go anywhere the Forester would have to look it’s best. While I had it up on the lift for a general, pre road trip, check over I gave the Genome exhaust a polish. Then out the garage […]
Forester STI – Whiteline Rear Anti Roll / Sway Bar
If you’re not already aware, A Subaru Forester is basically a jacked up Impreza with a slightly larger, boxy body. Those are the things that attracted me to one, the performance and tuning potential of an Impreza but with more space in the back for stuff. Being ‘jacked up’ and the ‘larger, boxy body’ both […]
Forester STI – New Fog Light Cover STI Decals
The left fog light cover could do with a new decal and a little freshen up with a layer of lacquer so I carefully measured the dimensions of the original STI decals and had an eBay seller make me some exact copies of them for me. I wanted to make sure I placed the new […]
Forester STI – How to Repair Brembo Caliper Threads
As I showed in my last post, when I replaced a rear wheel stud, Brembo calipers can cause problems when it comes to removing them. This is because they are an aluminium alloy and they are bolted with steel bolts. Galvanic corrosion happens between the two different metals which weakens the aluminium and it sort […]
