Putting a new motor in my Si, ive got a question
 

Replacing the motor in my Si because it was burning oil pretty badly and then got a real healthy knock.
I still have to finish taking apart that motor to see exactly whats the problem but in the mean time I got another motor local to throw in there.
My car is a 99 Si so you all know what came stock in it, the motor I have is a b16a3 which I am told has a different oil pump than the a2.
So do I just need the pump itself?
I was looking online http://www.hondaautomotivepart...82%29
and didn't know exactly what I needed of the parts mentioned here.

Also anything else I need thats different on between the two motors?
