98 2.7l 5 speed with 33X12.50X15 BFG MT KM's. I have no power up hills and if there is wind against me going up hills I may as well pull over and wait for the wind to stop. Just a little exaggeration but I need to regear bad. I emailed the guys at PORC but have not heard back yet.
I have the same engine/tranny with 33x10.50s. OE was 4.30s and I regeared to 4.56s taking me right back to stock performance (adjusted ratio of 4.28:1) but I still wanted more power, arr arr arr!
regeared to 4.88s when the front ARB went in.
around town and on the trail this is the way to go, hands down. but, if you do a lot of hi-speed hwy driving, like over 70 on a regular basis you gas mileage will suffer. If I keep it around 65-70 I can get just over 20 mpg but faster than that and it drops quickly.
there is a huge difference between the 56s and the 88s that I never expected. In lo range it's almost like having a crawler compared to the 4.56s...stress on the word almost
On the road I can cruse in 5th up small inclines again
get the 4.88s; if you ever decide to SAS and go to 35s you won't have to regear
