I think that D15B VTEC was the same as a D16Z6, so use whatever the Z6 uses.

But also if you use a ODB-0 distributor and fuel injectors you could make it ODB-0.

You got me. The only 4Gs with 2 injectors were the DX and STD, Si had 4. And then on the CRX side HF and Si had 4, DX had 2.

You can go with the P28 if you want to do a lot of rewiring. Or you can go with the Si harness, Si ecu (pm6?), si injectors and dist. You can make the dist. work, but it takes a little work. If you go with the pm6, you'd have to add in a vtec controller, or an rpm switch. If you go with the rpm switch, you might as well get the 2nd gen teg ecu so you'd have better fuel mapping in the upper rpms.
