Is it possible to run a D16Z6 crank on a D15B7 block...
i know rod bearings are different but what about main bearings, beacuse these are the important when swapping...

 

D15 mains are smaller.

 

anthing is possible if you have alot of money.

 

In theory it should be easier to machine D15 mains larger and use a D16 crank, than to build up D16 mains and machine it smaller to use a D15 crank.

Why do you want to use a longer bore in a shorter deck height block? I don't think you can find shorter rods, and you'll have to notch your block even more than you would than if you were just switching over to beefier rods, since the rod angle of attack (not sure what the term for that is) would be even wider.

 

why not just go with the D16 instead. Its not worth all that trouble and later found out it you could just get a D16 and save yourself some headache. my 2 cents

 

I was thinking about that, It would actually be pretty inexpensive.

 

except the info is all wrong.............

How do you machine a piece of metal LARGER

Now cutting a D16 crank down to work in a D15 has been done, but it required welding and offset grinding.........

it also went 10.77 NA in the 1/4

 

another BISI setup

 

Easy, add metal first of course. Duh.

 

I think he meant opening the main bore from 48mm to 58mm, then drop in a D16 Crank....

That would be about $600 in machine work alone.......
