b3/b6

after searching i am still a little confused. What b6 parts will go on to the b3? it sounds like the intake and throttle body only?

I compared my 93 323 mazda b6 to the stock festiva exhaust manifold and they are different and definitaly will not bolt up.

on the 90+ b6's u have to drill 2 holes in the exhaust manifold flange and it'll bolt straight up. My old car has a festiva header on the 91 323 engine that it has inside of it and it works great

everything is interchangable on those engines. I had the b3 exhuast manifold on my old b6 for along time. The only think you need to watch out for is the intake manifold. Some of the b6 intake manifolds have the coolant lines run differently and changing it out with the wrong ones will block off the coolant and overheat your car immediately.

there were different styles of B6s. The early B6's are virtually the same engine.. exhaust manifold will bolt up as well as the B3 intake..

my b6 is from an 89 323. Running the b3 intake and exhaust manifolds, bolted right up.
