20B Conversion Pg #4 Modifications & Upgrades

Now that our 20B conversion is complete, it is time to perform some upgrades and modifications to handle the additional power.

We upgraded to the Carbonetics Carbon LSD. The Tanabe Medalion exhaust was replaced with the less restrictive APEXi PS REVO system. We also installed Hawk HPS Brake Pads and the Tweakit Idler Pulley Kit.
