Default Re: Regearing?

screw the Dmax ( sorry to those that did it)
waste of $25k for 5 mpg gain and lots of torqe and some HP on a used engine and unknown install and problems down the line.meanwhile, your paying more $ at the pump to fill the same 33 gallon tank.

same amount, you can buy another H2, do some decent mods to it, have cash to $$$ to actually fill the tank, and take the GF or wife out.

when i return from my deployment, my plan is to:

Regear to 4.88- $2000 ( rounding up and adding hidden costs)
new long tube headers and exhaust - $1500 ish
new tuner - $400

right now
2003 H2 @ 100K miles
8.9 mpg city (according to the DIC).. and i would guess about 10 mpg HW (maybe more, maybe less). i dont have a light foot. baby shifts alot, but i love cruising at 80 MPH. ( love the looks people give as i cruise by people ont he HW)
4.10 gears
K&N CAI
year old tune up ( plugs only)
Diablo Tuner
37 BFG M/T KM2 on 20 rims

thinking about possibly swapping the heads out and manifold to gain alot more HP.. but i think my tranny is under, but near its limits and not far from starting to feel abused. i would love to get a 6 spd tranny from a new H2 instead of the 4 spd i have now.

ill run this into the ground, and when the engine is dead, i will do a 600+ HP RWHP crate engine and a 6 spd tranny rated for 750 HP and do it all over again.
