LR Parts do a kit but it says 200/300 tdi upgrade. https://www.lrparts.net/catalogsearch/result?q=POWERboost+Kit+for+Non+ABS+Land+Rover+Defender+300tdi+%2F+TD5%2F+TDCI+-+available+with+or+without+Servo

Just want to make them better, they work fine but see you can upgrade them but upgrade says 200tdi/300tdi

I have a ex military 110 1985 land rover and see you can upgrade the brake servo to the td5 i think. Is this possible on my land rover? If not is there an upgrade? SilverFox44
