1- Engine dynamically balanced and carefully assembled using stock CR pistons/gapless rings.
2- Cyl heads with 1982-1993 6.2L "C" series precups.
3- DSG - Phaser or gear drive timing set.
4- If DS4, set TDC-Offset to -1.94. If DB2-4911, set timing up to 5 degrees BTDC.
5- Hi-pop injectors.
6- Free flowing exhaust - including port matched exhaust manifolds and 3-1/2" mandrel-bent exhaust system.
7- Turbo set to produce 3-5 psi at a 65-mph cruise.
8- A 4" lowered 2WD 1500 series truck/Sub with an under-bumper air dam, and riding on stock size radial rubber at max air pressure.
