Or just some ways to get more power. i already have a weber carb (dgav33b1) plus new plugs and wire (ngk). it just seems kinda gut less.
thanks for the fast reply. so is there any tricks i can do to get a little more power then? I wasnt really fully wanting to do the engine swap but i would like more power.
The KA24DE from a later D-21 will bolt to your transmission. You will need to convert to EFI or Remove the CAS and install a distributor so you can run a carb. There's a guy on Ratsun that has done this.
