Been looking at the three vehicles. The listed vehicles would be a
2002 up Ecotec 5 speed
1998 up GT or GTP
1998 up F-body 6 speed
They all will get about mid to high 20’s on the highway. With I/H/E, a wideband, HPTuners, and a possible methanol kit, their power will be much different between the three, but so is the weight. Would like to end up with mid to high 30’s on the highway. I know that tuning for max MPG wouldn't necessarily mean the most fun, but I think it would be challenging to get it working all together. I guess power goals would be to run in the 13's or 12's, but not much of a drag racer.
J-body
Pros
Smallest engine
5 speed
Smallest vehicle
Cons
Not very fast, and would need a turbo to get up to the power that I would like, plus the lack of a 2 bar MAP sensor
W-body
Pros
Boosted from the factory
HUD
Cons
Huge
Automatic Transmission that doesn’t like any power
F-body
Pros
6-speed
RWD
Torque
Lean cruise?
Cons
Probably the highest insurance deductible
Highest purchase price.
If you choose other, let me know what and why.
