since the vitaras are low deck height in a d16, why not get your crank lobes welded up and offset ground, or just undersize them off-center? poormans stroker kit for the most part.

seems logical, but why does noone do it?

becacuse FJT sells custom rods for vitara setups :1

not the point i was getting at.

you can use the lower deck to stroke the motor and not play kissy kissy with the head to piston clearance

I'm assuming the machine work cost would easy pass the cost of vitara slugs and aftermarket rods.

Also stock rods can't handle the HP that H beam rods can.

I think he meant stock rod length.

you can use a d17 crank w/ 137mm h-beams w/ d16z6 head and gasket =9.10:1 found this using http://www.zealautowerks.com/dseries.html.
Using FJ's rods 138.65mm you get 10.43:1

Again that would kinda defeat the ideas of using vitara for mega boost turbo or supercharger setup.

That machine work to a crank would be very expensive. Welding on the lobes would cause all sorts of problems and give many sites for crack prorogation. Also, there is a very precise radius that needs to be at the edge of the bearing surface to prevent fatigue failure. The journals are also case hardened.

The d17 crankshaft isnt going to help the d series motor it has enough stroke. What the d needs is work up top. manifold,throttle body,ported head,camshaft then your done.
