I got this idea from the zeal compression calculator it gave me a compression ration in the 11's. my question is it even possiable to put a D17 crank into the D16 as a bolt on affair or would I need to make changes to the block has anyone done this before?

 

I think it's been talked about a lot over at http://D-series.org

Try doing a search over there, you should find what your looking for.

 

Possible, but I never seen it done before, so I don't know.

 

i think it would basically make it a d17 with 16 pistons

valves meet piston, piston meet valves

 

be sure to CLAY the motor before you run it

Yes, it is possible, in fact, that is what I am running right now. You need to notch the block and main girdle for the rod swing. You will need to carry over the crank/rods/pistons/oil pump from the D17, or have custom pistons and rods made if you are looking for more than 280whp. I am running right at 260whp at 11 psi right now, on stock rods with polished beams, and stock PLR pistons .020" over. You will also need to run a b16 crank pulley, or bore out the stock D16 crank pulley to match the D17 crank snout. If you are using a D16Z6 block you will need to modify a D16Y8 rear main seal housing to fit. If you are using a D16Y8 block, you will need to drill the oil pump for the dipstick. Either way, you will need a Y6 or Y8 oil pan.
