western Posted February 2, 2006 Share Posted February 2, 2006 I think Nige [Hybrid from hell] posted something like that or it might just have been a chart. Quote Link to comment Share on other sites More sharing options...

landrover598 Posted February 2, 2006 Author Share Posted February 2, 2006 Well after playing with the numbers, changing to a disco lt230 and 33" tyres may be a bit too high geared I'll see what difference the bigger tyres make first before deciding on changing the box Quote Link to comment Share on other sites More sharing options...

landrover598 Posted February 2, 2006 Author Share Posted February 2, 2006 Thanks for the offer, but i've got it sused now, from Marks program i just wanted to see how much difference the transfer box and tyre size makes just need to find the money, parts and time Quote Link to comment Share on other sites More sharing options...
Mark90 Posted February 2, 2006 Share Posted February 2, 2006 OOPS sorry Mark didn't remember it was your info/program Well it was Nige's program that has been on here recently, mine was posted a few times in the dim and distant past on LRE board. I'll run it for you, it is very very accutae. Oi what you saying about mine It's as accurate as the data that you put in it, that calculations are correct, although I haven't factored in any slippage in the torque convertor for the auto boxes Quote Link to comment Share on other sites More sharing options...
landrover598 Posted February 3, 2006 Author Share Posted February 3, 2006 I presume the 1.2 box is a straight swap for a 1.4 box ? or did land rover in their wisdom make them completely different Quote Link to comment Share on other sites More sharing options...
Mark90 Posted February 3, 2006 Share Posted February 3, 2006 Aye straight swap Except possibly for the handbrake cable bracket mounting holes are different between the RR and defender setups. Nothing to trouble a chap of your abilities Quote Link to comment Share on other sites More sharing options...
landrover598 Posted February 3, 2006 Author Share Posted February 3, 2006 B) Excellent I've got one of those fantastic disk handbrakes so no problems with the brackets Quote Link to comment Share on other sites More sharing options...
