A friend of mine just bought a 93 civic with a b16a2 swap and within a day it died on him. I need to know if it actually has a b16 head and dizzy. the head is a pr3-4, and the dizzy is a td81u. ive searched but all i get is marketplace people selling stuff. if it is the original dizzy what is it interchangeable with. thanks for any help.

 

That's the correct code for B16 head, and the correct part number for a B16 distributor.

I found all this by going here

 

google is good and all but in most situations i like to get info from someone who might kinda know what theyre talking about, maybe someone who has a 99si in their garage and knows for sure. thanks tho.

 

I have a 99 B18C ITR motor (PR3-2 head) TD-87U and TD-84U will work too. I have one actually, it's after-market though, but it works. It starts to flip out around 8200 RPM ... Go OEM if you need to replace the Dizzy.
