I'm currently having a 200tdi conversion done to my 90. I have been told that a disco transfer box will make improvements. However I have read that a 90 and 110 have different gear ratios and that the transfer box will not make a lot of difference to a 90. Anybody know anything or can help out...

Hi everybody. Am new to landrover and forums. Bought an 89 defender 90 a few months ago. Am learning slowly and have done a lot of restoration and work myself. It's currently having a 200tdi conversion and a new bulkhead fitted by North west land rovers. Can't wait to get it back.
