Ok I have a 1986 diahatsu hijet. I have removed the clip from the tranny to shift to high gear and works great. I have also unscrewed the govenor from the Speedo input and screwed the Speedo cable straight in so that I dont cut off at 25mph. That works fine. Problem I am having is I need more power. As far as I know this truck is bone stock. For instance, going up the slightest incline on the road and I am unable to get it to turn up enough rpms to shift to 4th gear. It's like there's something holding it back. Can you guys tell me what all performance upgrades I can do to this truck to get the most out of it I can? Thanks in advance.
