Hilux 2.0 Liter 'advice'

[Mod]

Hi, im gona get a toyota hilux 2009 model in a week or two, and need some help deciding which version to pick

im going with single cab

1) single cab 2.0liter 2WD

2)double cab 2.7 4x4

i wont be using it for off raoding or anything like that, just street use, so i said ill go with the single cab 2.0liter 2WD ,

the 2.0 liter and 2WD version is a little lower, smaller tyers and a less powerfull engine, will the 2.0 liter still be fine or will like be very slow?

one more i would like to raise the car with out changing gears and stuff is that possible, and how high can i get the hilux?

i wana also put slightly bigger mountain tyers , will that kill the acceleration and speed, coz its 2.0liter ?

i currently own a toyota fortrunner and am happy with its rigidty and was hoping for some first hand opinions about the hilux, is it strong ,rigid, body and engine wise?

can i modifiy or accersorise anything else on the hilux or is it limited?

i would like to also increase the hp of the 2.0 liter . can that be done on this vehicle?

is there a big diffrence between 2WD and 4WD?

thanks you sooo much!
