COBB Tuning Blog

At COBB Tuning we spend a lot of time working on our customer’s cars or building new parts for better performance. After working hours, we turn our considerable talents to our own cars. While snow covers most of the ground, it’s time to perform major surgery on our rides, like COBB Tuning Surgeline tuner, Lance Lucas’ 2004 WRX Wagon. With a built engine and larger turbo, Lance has transformed his grocery getter into a serious Hyper Wagon!

“I recently finished this rebuild on my personal car, a 2004 WRX Wagon I’ve owned for about 3.5 years,” said Lance. “The last setup was a 2.5-liter hybrid with an 18G and EWG (external waste gate) on E85 that I used, abused and eventually destroyed at the dragstrip. I refused to let a broken OEM piston slow me down and immediately began the rebuild. We made the active decision to build the car using commonly available, proven products as a good example of what can be acheived with a “budget” build by Surgeline, without our normal touches — no AN fittings, no V-Band flanges, no Tial exhaust housings, no rotated manifold, etc. Everything has turned out wonderfully and my car is a great example of the potential available using the good-ole K.I.S.S. principle.”

“These are the preliminary dyno tuning results, at both wastegate (16psi) and a couple days later at 22psi tapering to 19psi or so,” said Lance. “At a very rich .75 lambda I am out of injector at ~21psi, so I kept boost low on top for the time being. Timing curve is extremely soft as well. My long-term plan is to add a second Walbro in-tank and raise base fuel pressure slightly, then tune to 450whp on E85 for daily driving and hopefully an easy 500whp on C16 for drag strip fun!”
