haha 130 outa a .9 3cyl hijet i thought was pretty good =P. point is my 1.6 cant keep up with it! lol

3200 doing 100 in 4th would see you doing what, 2700 in 5th??? thats about the RPM im doing at 80km/hr in 5th, and its definitely got acceleration from that rpm up to 100, wouldnt need to touch 4th to accelerate quite fast either.

i think like others suggested - get engine checked for fault codes first - takes 2 secs and might get you an answer much faster.

not trying to be cool , but in my old zook, i got 130km/h in 5th, running about 30;s with my g16 carb motor, i know have that engine in my new car with another set off 30's, but have corrected the gearing to suit the 30's this time

i would of thought a g16 efi is alot better, so i reckon its has to be some thing to do whit your engine, if you cant get more then 80km/h in 5th

like fatzook said, correct your gearing by getting urself a set of transfercase gears and see if hat fixes your problem

i dont see how it could have anything to do with the engine when from 1st to 4th it goes great. its just 5th gear were it dies back to 80. might haveto try some gears i think

[atari4x4]

maybe put standard tyres on it, take it for a run & see how it behaves

[4x4zook]

that sounds like a plan

oh btw with the o2 sensor the wire from the o2 sensor to the ecu, does it haveto be the real fine wire type that comes off the o2 sensor or can i use just normal "cd player" stlye wire u buy from supercheap to run it back to the ecu?

Stock gearing for a WT and an uncorrected speedo should see you at an indicated 100KPH in 5th gear at around 3300RPM. My G16B with stock gearing and 30's still pulled 100 ok in 5th. 4th gear would wind the speedo out well past that easily.

Mine was doing the same and i just got the check light hooked up. I now know that i need a new MAF sensor. So id say thats whats holding it back. The reason it does it in 5th is because of where the revs sit, if i get mine upto 120 it holds it better then 100kmh.
If you dont have a check light hooked up pm me and ill do a write up on how to check codes with a 50c globe and some speaker wire

my g16b vitara revs about 3200 at 100ks on 215/75s
ive got it upto 155km/h on a motorway too
i reckon try some stock tyres and see how that goes
