The last time we saw Matt Sims’ BT1 at the track the car had just dipped into the 8-second zone. Since then a few wholesale changes have been made. The Nissan RB30 features a solid camshaft and is now boosted by a Precision 75/76 turbo at over 40 pounds of boost as well as an upgrade to a Haltech Elite ECU. A stronger Pro9 rear end is also in place.
