Forester STI – SWRD 3 Port Boost Control Solenoid

The OE Subaru boost control setup is not as good as it could be so when wanting to increase the boost and gain better control of the turbo actuator a 3 port boost control solenoid is really worth fitting. ScoobyWorx sell a known good 3 port solenoid with the correct plug adapter meaning I wouldn’t […]

Forester STI – Turbo Back Milltek Exhaust System

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 – Spark Plug Change

Time for some new spark plugs and while I’m at it an upgrade to a cooler running plug in preparation for more boost, more on that another time. From what I read, the spark plug to go for is the NGK ILFR7H. This is more of a job than with most other cars due to […]

Forester STI – New Rear Discs and Pads

I had already bought a set of rear discs and pads when I bought the set for the front from Godspeed. I didn’t fit the rears at the time I did the fronts as there was a decent amount of life left in the pads. Now it was time to fit the Godspeed G Hook […]

Forester STI – Noisy Power Steering Pump Fix

As the title says, a simple fix here for what I was worried might be a more costly and involved job of replacing the power steering pump. The symptoms were a whining/whirring noise when maneuvering the Forester in the driveway or when parking so when going from lock to lock. This began happening on cold […]

Forester STI – MeisterR Zeta CRD Coilovers

While I didn’t have a major problem with ride and handling on the OEM STI springs and inverted dampers (the stiffer rear ARB and subframe locking bolts really helped, see here and here) and I didn’t mind the STI ride height with the Prodrive GC-010E wheels either. But with the Rota Grid Drifts, the standard […]

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 – Sloppy Gear Change Fix

There was a bit of play in the gear change. To be honest it wasn’t too bad but I really hate feeling any slack in a cars controls so I took a look at the linkage to see if I could find anywhere with any slack and if I could do anything to tighten up […]

Forester STI – Engine, Gearbox and Diff Oil Change

Whenever I get a car I tend to change all the oils early on so I know it’s all fresh and decent quality stuff. The Forester was no different so I got myself some Millers oils for the engine, gearbox and differentials and a genuine Subaru engine oil filter and sump washer. For the engine […]
