I have a sr20 blacktop and looking to build another sr20 longblock over the winter. Was wondering which parts are NOT interchangeable from black top to red top?

from what i know S13 SR20 Blacktop and Redtop are both the same, there is no difference between the two.

Bottom ends
Yes S13 R/T and B/T are exactly the same.
S14 SR Oil pump and water pumps bolt holes are different.
Internally they are the same, Heads are obliviously differnet

The blacktop I have is an S13 blacktop, not an S14 blacktop.
Sorry for not specifying.
With that, the heads are the same, correct?

Everything is pretty much the same and will interchange with each other...
