Can I add a blow off valve to a black top sr20det?

[patrick_kouki]

Sorry if this chat already exists my phone kept bugging out while searching. Anyways, i have two questions. First, what is the difference between the black top and notch top? (If they're the same thing my bad I'm pretty new to the sr20). My second question is can you add a bov to the sr20? Btw I have a 1995 240sx s14 if it helps. Thanks!

The Difference between the S13 blacktop and the S14 Notchtop Blacktop is that the S14 has variable valve timing, intake ports on the lower part of the head, better valve cover for air/oil separation, wiring of course, and a T28 turbo. Those are the main differences. There are other small things of course, but I don't feel like listing everything, ha ha. And yes, you can add a BOV to any turbo engine.

When you say add, what do you mean? An SR already has a bov. Are you wanting an aftermarket one?
