Reverting a special Subaru to OEM+

Project Management

ECU tuning & general refresh

Vehicle: 2010 Subaru R205 (1 of 400)

Purchased into collection by owner

Reinstate engine control to factory ECU with map adjustment and safety system. Remove unnecessary external boost controller. 

Reinstate R205 specific 6-4 brake system, sourcing STI specific pads + aftermarket rotors. Replace straight pipe with original HKS Legamax system for better sound and NVH.

Repair STI Spec-C specific power steering pump. Repaint, polish & detail overall and replace stone guards.

Install head unit - sourced unit fits originally styling and paid attention to unit with matching backlight colouring as the rest of the interior.

When we picked up the car it had an aftermarket boost controller which was also plummed in wrong. This cause extremely high levels of boost for what is still a stock engine and no control. On the drive home we saw 1.8 bar of boost!

Can't understand why one would use such an aftermarket boost controller which means there is 0 control by ECU. No factory safeties. No 3D mapping for the boost control.

So we removed this boost controller and plumbed the boost solenoid back with the factory ECU. Later on the boost was then adjusted using factory ECU.

Front bumper had awful cheap aftermarket bumper spring/clips to make it look race car....it just looked shit. So these were removed and the holes filled in and the bumper repainted.

The reversing sensors were also "fixed" by Subaru.

The power steering pump was rebuilt as it was leaking and making noise and they are very expensive to replace.

All fluids were changed.

The straight through exhaust was changed to have a HKS backbox

Some more gauges removed and wiring cleaned up

Spare key made

ECU was tuned to make a little extra power but still be safe and to also have better throttle linearity as well as different boost levels between the different

Modes
