I need to know if the center-to-center spacing is the same between the B-series and C-series engines. I also need to know the bore diameters. It relates to the engine swap rules for my region.

 

No one?

 

What the hell is a C-series engine?

 

i think c32 was the acura legend engine

 

what is he trying to swap a 6 into a prelude? Interesting, costly too.

 

i dont think so, he's comparing it to a B series

 

Ooops that was supposed to be D-series vs B-series

 

Sorry dude, the D-series and the B-series are not swapable. You have a D block and want DOHC right? Well, you are going to have to purchase a whole changoever.

 

That's not what I asked.

My rule book says that internal engine mods are allowed (any and all) with the following limitations:
1- Bore spacing must remain the same
2- Drive configuration remains the same

So as long as the D-series and B-series blocks have the same bore spacing I can do a full swap and call it "Internal Engine Mods".

So again I ask my original question (a concept that this board often struggles with); what is the bore spacing (centre-to-centre) of the B-series and D-series engine?

That's it! No advice. No "We need details". No "I think you should do this". Just the bore spacing!

Look in your damn manual then

The spacings have to be the same center-to-center. Other wise you could bore the engine to change the spec. But thank you for being the first person to attempt an answer!

And I don't have the manual since I don't own a civic. There's no point buy a shell if I can't compete with the car once it's done.
