What size and thread are the bolt that go into the engine block(though the bell housing of the transmission.) i know ill probably get flamed but i need the info for mazworx(making my adapter plate)

 

I think 17 from the tranny side. 14 or 13 from the engine side.

 

For the heads of the bolts, yes it's 17mm and 14mm.

OP: I'll try and get you the size and pitch when I'm at the shop tomorrow. I'd imagine for the 14mm head bolts it's M12x1.25, for the 17mm head bolts maybe M14 or M15.

 

okay, sounds good

 

I was a bit off; 14mm head bolts are M10x1.25 and 17mm head bolts are M12x1.75.

Come to think of it, the M10 might've been x1.5, but it should be 1.25.

 

oh oops. i thought he meant the sizes of the heads. haha.

 

thanks a bundle for the help, if you were wondering the adapter plate is so that i can put the 350z engine into a pontiac fiero, using a megasquirt setup.

 

Any updates on the parts

 

nobody has touched this thread in 8 years, the same time frame it has been since the OP logged in

 

Interested in both parts ASAP.
