alright so I have the d16y8, I have an aem v2, skunk2 intake mani, (getting the skunk2 TB, and Comptech Header) and I have a megan raacing catback. Im thinking of saving up for a b16a2, but will any of the parts I listed above bolt right on to the new engine? Or do I have to buy all new parts?

 

exhaust - yes
throttle body - yes
intake - kinda sorta but the mount will be wrong

everything else - no

 

so the intake manifold wont?
If the throttle body will fit, wouldnt the intake also fit?

 

no. see different part numbers http://www.skunk2.com/Engine/index2.php?prodId=imd

like I said, the MOUNT will be wrong. The intake attaches to the transmission and the bolt pattern on the D-series tranny is different from the B.

 

oh ok thanks
