Well apart from the engine mods... semi-slicks tyres and omex launch control rev limiter. Later on quaife gearbox with paddle clutch and quick shift.
With just the cv35 camshaft, motorcraft chip, bigger intercooler and semi-slicks tyres I did 0-60 feet in 1.9s. And the Orion is a bloody heavy car. Finish line with just these mods 13.6s. Now I'm eager to try to go down to 12s after 2 years spending money while in the garage!
