So I have a question for the board. I currently have a d16a6 in my wagon that runs good but burns a hellish amount of oil. I have a low mile d15b2 and an unknown condition d16a1 sitting in my shop. I can't swap the complete d15b2 because it does not have the cast in pads to mount the intermediet sp? shaft to the block. What I am thinking about doing is taking the head from the d15 and the pistons and rods from the d16a1 and putting them on/in my d16a6 block. Would I be better off just rebuilding my current motor or do you guys think that my franken build could work. From what I have researched the d16a6 and the d15b2 both use the same head casting. I know the cams are differant but are the valve springs the same? The d16a1 pistons with a pm3 head should run about 10.5 compression as opposed to the stock 9.2 with the pm6 pistons. The biggest thing I am concerned about is the fact that from my calculations I will be running zero piston to deck clearance with the pg6 pistons as opposed to the 0.020 clearance with the pm6 pistons. Will this be a problem? Also will the d16a1 rods work properly with the d16a6 block and crank? Sorry for the long book and thanks for reading.
