Re: 1HD-t vs 12H-T vs TD42TDi for WVO
There is a little group of us in Perth developing more power with our 12h-t and these build ups are being covered on other forums as they are not really related to vege oil.
I agree with Nuddy's assessment of the Nissan motor, and for vege use it is probably a better proposition than the 12H-t in some ways given the IDI head. They also come with intercoolers which is a real bonus.
However I have proven that with good management the 12H-t direct injection is a fine base for vege, and being DI, the extra power that can be unleashed over the Indirect Injection engines make the 12H-t a lot of fun to play with. Running on vege means I can use that power quite happily and not be at all concerned about the cost of the extra fuel I might use.
