Subaru WRX 2.5L

Subaru WRX 2.5L

Gaining horsepower cannot come easier than this.... simply increase the size of the turbo to a bigger one, add a boost controller for controlling boost and tune the car using ECU Reflash method. And there you have it, 320~350 bhp on crank!

Everything else remains stock except for a legal aftermart exhaust system that produce a low bassy boxer blurping rythem. Trust Pe-Ti I think... not sure...

The owner of this ride is not unfamiliar, he used to drive the Honda civic esi turbo charged running 0.9 bar of boost. Now upgraded to pacific muscle car and done some minor modification. I told him his setup is very boring la... hahaha... he just laughed and told me, more to come, and will definately create a monster in due time... give me heachache like the last ride .... hahahaha...

This setup is for people who really enjoy the stock drivability and want to enhance it further. You basically want a car with a power packed mid-range. You get to rev all the way to 7500 rpm on this euro spec Wrx, while keeping in mind the best power come from the 4000~5500 rpm.

So, idling is perfectly stable, boost wise, is whatever we set and comes on strongly at 3500 rpm on gear 3. Pulls hard till 5500 rpm. At 5500 rpm, the turbo loses breath and continue to push the car till 7500 rpm. Torque wise, I think the 2.5 packs more than 2.0. Largely due to the earlier and faster build-up of boost.

p/s: after tuning this ride, i went home and tune my own car to make it 'feel' faster la... last time i have a policy that i only tune car slower than mine hahaha... nowadays like not very relavant liaoz... now my car feels like tortise hiaz hahaha... need to mod !!

cheers
