On my quest to bolt 35"s under my 80, I've come across a problem - I need more power! The easy solution- Diff reduction gears ( a new diff ratio).

Can someone put forward a recommendation on a cheap (but decent) mob that can set me up with the gear I need? I have had prices of $550 per end so far- Not quite what I was expecting.

Has anyone gone this path, and can they provide any other recomendations? I am not dropping the box on my cruiser again, so a set of rock hoppers is pretty much out of the question, and Im content with having 2 sticks to play with- I dont need a 3rd.

4.10 is std, 4.55 and 4.88 and 5.29 are out there...they are available from the states or through most 4b places check out manell motors...550 per end may get you the gears, then you need to fit them....id suggest you buy a turbo, and do it that way...3k and you can cruiser all day at 110. No spedo problems, etc etc etc.
Now on outerlimits there is a 1hdft motor that will bolt in for 4500....thats got enough power to turn 44's.

Well I fitted 35's last year & did notice poor acceleration from 80 km hr. however after having a full pump & injectors job done by MTQ , the perfomance is better than original which was also varified by before & after dyno readings . The motor is an 1HDFT @ 200,000 - also the Speed Shop at Castlemaine does speedo corrector boxes .

Jaycar do a kit for Speedo correction as well, far cheaper than Castle or Marks.

As much as Id love to get a turbo, it means a turbo timer, and that would mean working on the handbake again to get it working... that just spells trouble. see I've got this disorder where when theres a working handbrake next to me I just have to use it every chance I get which of course makes it useless again a few weeks later.
So as you can see, a turbo is more work than its worth.

That and as soon as I save the $3k for it im taking off out of the spinafex here and into the rainforest for a few weeks.

I heard stories about how good the HDFTs are- thats pretty impressive.
Hows the fuel consumption on it?

Dunno about the HDFT consumption, but I regularly get 12.4 l/100km out of my 1hd-t (2 valve T/D).

If turbo timers are so important, why dont they come with them from the factory....they are a good idea if you are letting everyone drive your pride and joy, but un needed if you idle the motor for 30 seconds...as the factory turbo is water cooled, it stays cooler...if your at the top of big red, then 2 minutes, other than that, 30 seconds....now on www.pickles.com.au under quick search for a cruiser, there is a 98 40th annaversary 80 series that has been rolled....if you get that for 5k, and you can selll your donk for 3, that leaves a shoretfall of 2k and alot of spare parts like ABS, interior, wheels, etc etc etc.
The front lawn wont look that good though!
