Could a Nissan bluebird Manuel trans fit in a c34 Nissan Laurel???
Neither of those cars are sold in the US under those names.
We do have a few members of this forum that live outside North America but you chances of getting an answer would be better on a Nissan forum.
What I can find out is that a RB transmission is the easiest swap on these cars. Think R33 Nissan Skyline for example.
I’m guessing you don’t live in one of the 50 states?
Heck, I can’t even pick out a Nissan from a row of 3 parked cars and I’ve never heard of a “Nissan bluebird” or a “c34 Nissan Laurel,” but in the U.S.A. we sometimes defer those questions to a salvage yard (junk yard, used auto parts business, auto recycling yard). They often have access to that information. Hope that helps!
What year Bluebird? Is it FWD or RWD? What engines are in the Bluebird and Laurel?
