I bought this car mid 2015 for a great price with nearly 200,000km on the clock but an engine only 60,000km old (replaced by Subaru under dodgy-bearing warranty for the previous owner).

Intentions were/are to boost the performance but keep it subtle/practical so I don't get unwanted attention and to keep full practicality with towing, climbing gutters etc. Accordingly lowering is off the agenda and a swap to 18" wheels is unlikely.

I very much appreciate the information posted on this forum (particularly by other SH owners).

[Kw line not reliable on the graph below 4000rpm due to auto gearbox slipping/flaring. Fine on the road. See full comments on page 10.]

Miscellaneous pics

Image

Kap catch can for head breathers (shown with engine cover and intake snorkel removed). I'm really pleased with how invisible/factory this looks. Pic taken before the standard MAF pipe was replaced. See how squashed it is between the Perrin turbo inlet pipe and standard airbox.

Image

"Invisible" hoses etc with the covers on. Black-painted brake stopper also shown.

Image

VF46 ported on the far side of the wastegate exit ramp. The theory is that exhaust gasses can race over the wastegate exit hole and keep going without striking a nasty right angle.

Image

Turbo inlet slightly widened in a lathe to reduce the lip.


Image

Typical in-dash display on the head unit from the torque app. Keeps the interior looking factory, saves money on gauges and has near-unlimited information display possibilities. One benefit the SH model has over the SG is the stereo head unit is closer to the driver's eye line for this sort of information display. Beats decent handling and frameless windows any day...

This Mishimoto "compact" catch can is surprisingly heavy in standard form.

Image
some time on a milling machine will see about that...

Image
The 35 grams saved is probably worth a whole second on the quarter mile :D (base subsequently painted black)

The Perrin turbo & dump pipe blankets are not cheap or pretty, but they are effective. You can briefly touch the surface of the turbo blanket with a bare hand after a drive. I'll consider an aftermarket heat shield but am in no rush.

Cusco stopper and Kobe MAF pipe installed subsequent to this photo.

This picture shows the Kobe Motorsports MAF/SFB pipe trimmed to fit and installed. Note the difference between the Kobe pipe and the standard pipe which was "squashed" between the standard airbox and the Perrin turbo inlet pipe.

The trick to trimming the Kobe pipe was to trim asymmetric (wedge-shaped) sections off each end to rotate the pipe (clockwise) more straight between the airbox and Perrin turbo inlet pipe. Hose clamps are a great cutting guide.

I've coloured over the Kobe Motorsports logo with a black marker pen to keep the engine bay looking more "factory".

The two hot water hoses from the header tank have been wrapped in silicone tape to prevent abrasion from the hose clamp bolt heads. Space in that area is a bit limited now due to the catch can hoses so the hose clamp bolts need to be on that side.

The picture also shows the black-painted Cusco brake stopper.

Looks good mate! Vf46 is a great turbo for these things. Had one on mine!

I have a stereo fascia that will fit your headunit in without the gaps if youre keen?

Cheers for the comments. I bought Swinno's fascia too and will sort out installation soon.

---

This weekend i installed a cheapo ebay 10mm ball valve on the head-breather catch can:-

Image

[photo taken from under the driver's side of the radiator.]

I had both drainage holes plugged with bolts since installation. As it turned out I needn't have rushed to install a ball valve on one drain hole since there wasn't a drop of oil from the bottom of the catch-can from the 6 weeks since I installed the can. There was a greasy residue around the top of the catch-can where the head breather pipe goes in, so it's collecting oil very slowly.

Clearly there isn't a lot of head-breather oil to worry about and the large volume Kap Industries catch-can is overkill for that half of the oil vapour system (the other half being the PCV system - different catch can to be installed). Still, the Kap can fits beautifully in the next-to-radiator space and there is no harm having more capacity than necessary. I'd rather have the grease build up in the can than in the intake system.
