| Mod | Cost | Reason | Install Time | Result | Rating (1-10) | |
| Home-made Skip Shift Eliminator | $1.07 | 1-4 shift is a crime | 20 minutes | The car shifts like it should - a must have! | 10 | |
| Foreman Ram Air Kit, MTI Clear Lid, K&N Filter , and Free Ram Air Mod | $212 total from ls1motorsports.com | Stock intake setup is beyond restrictive - they did a lot of engineering just to keep air from actually getting into the engine. They wouldn't want the $20K cheaper Firebird and Camaro to have the same rating as the flagship Corvette would they?! | 10 minutes for the lid & filter, 30 minutes for the Foreman Ram Air Kit | Picked up approx 3 mph at the track | 9 - for the price, it was worth it. | |
| Comp Cams 26918 valve springs | $145 | allow for higher revs and will compensate for heavy stock valves | ||||
| Hardened pushrods (Comp Cams) | $119 | Stock pushrods bend easily | ||||
| Comp Cam with 114 LSA probably 222/222 or 224/224 (maybe the Thunder Cam?) | $400 | Over 50 RWHP hopefully! The Cam would make less power under 4000 RPMs...but really shake things up to 6500+ RPM. | ||||
| Hypertech 160 Thermostat and SLP High Capacity Radiator | $50 for thermostat, $300 for radiator | Cooler engine means less chance of detonation and more power | ||||
| NGK Plugs (TR55 for stock, TR6 for turbo) and Wires | $20 for plugs, $75 for wires | Stock plugs are not very good - usually worked after 10-15K hard miles. | ± 5 hours | |||
| SPEC Star Stage 4 Clutch/flywheel | $500 | Stock clutch is almost worthless | ||||
| LS1 Motorsports street/strip turbo kit | $6,000 | 200+ RWHP and 300 ft/lbs...nuff said | ||||
| SLP Headers, 1 3/4" Tuned/Long Tube | $849 | SLP claims big gains. According to this guy, he gained a half second and 5 MPH. (he gained 21 RWHP and 34 ft/lbs) This won't happen if I decide to go with a turbo. |

| Custom 2.5"-3" dual exhaust with X-pipe and high flow catalytic converters. | $380 for the cats / $100 for the Dr. Gas X-pipe / unknown for the custom exhaust ($600?) | Will be needed to allow the engine to make more power and have a great sound. | ||||
| SLP H.O. Hood | $800 shipped | It looks good. |
