Its not as big as a big block, but is just as heavy. If you are staying stock, its not a big deal but if you plan to hotrod your Dmax, start looking at the cost of some of the parts. Building a high end Dmax is expensive. The only company I've found so far that makes a stand alone engine harness is PPE, the guys that did the Dmax Chevelle.
I think its a cool idea, I hope to follow your project if you go at it. Just don't expect to be very popular, I've built against the norm and caught lots of flak. Thats how I came up with my screen name
