Mick Posner's WRX Wagon

Potent Performer:

Mick's Sonic Yellow WRX Wagon is a real sheep in wolf's clothing. It's fully built 2.5L with Darton sleeves, Oliver rods, running coated CP pistons all fully blueprinted and balanced. The V7 large ported heads have had additional porting, 1/2mm oversized valves, dual springs, shimless buckets and Kelford 272 intake, 264 exhaust cams. The Perrin GT30R rotated turbo setup supplies the 23 psi boost on pump gas and 28 psi on race gas. Mick is the author of the UTEC Quick Tune Guide which is deemed a must read for all newbie UTEC tuners.
