g'day all,
Im wanting to put either BFG 33/10.5x15 AT's or Cooper ST 285/75x16 on my 2003 Hilux V6. What my concern is, with my current 265/75x16 BFG's they sap alot of power from hilux. It's not bad once the hilux is up and moving but it's getting off the line that's the problem, it feels like it's lacking torque!
Which is why I'd like to replace the high and low gears on my transfer case with the bigger tyres im thinking of putting on. I want the car to accelerate in high range slightly slower than stock (I reckon they were geared wrong from the factory which is why alot of V6's blew rear diffs), and the low range to allow me to not quite crawl, but abit slower than the previous models 3.0litre diesel did in low range.
I dont know where to go to get this done right in
Melbourne(west or north preferably) and which ratios should I get fitted to give me the driving characteristics im after, and how much would it set me back?
any advice is appreciated,

Try some number crunching on this & see what suits you best.
Changing transfere case gears wont do it, you will have to change the diff(s) ratio

Dont meddle with the transfer gears as that wont help. You need to change both the front and rear difff ratios to get the that extra oomph that you are after. Try the snakeracing website as they have a an extensive range of diff ratios and will probably find one to suit your needs. But remember to change the speedo drive gear where the speedo cable goes into the gearbox. Not difficult to do. If you dont change the speedo drive gear, you willl have a speedometer that is grossly over or under reading. But to err on eh side of caution and have a speedo that over reads.
Mine over reads by 5 KMH. Hope that helps.

ive fitted meself the Marks Adaptors variable ratio box which corrected perfectly the speedo, which was 9% out of wack with the 265/75x16 tyres fitted. good product, easy to install and works
well.
Just thought I'd mention that.
