will the ehayset and intake manifold for the twing turbo off the third gen mount up to the 2nd gen or are the bolt patterns different?

 

There's a way to do the intake swap. I've seen FC's 13BT motors with the upper intake off the 3rd gen before. I dont know about the exhaust. I've got no experience with turbo cars but i would imagine you'd have to use the manifold that fits your turbo. i believe the exhaust ports on the actual block are the same though (should be... it's basically the same engine)

 

the lower intake manifold does not even come close to bolting up, yeah with some modifications the top will work. i believe the exhaust will work, but i dont see the point. buy an hks manifold and throw a bigger single turbo on it.

 

helped a guy do it before. no noticable hp gains, big headache and waste of time.
