I dont know much about the swaps in hondas, but i have a 92 civic w/ d15 in it. i need to know if i can drop in a b16 sohc vtech and use the d15
transmission, and if the d15 header will bolt up to the new b16. any other info would help, thank you.

 

If you want Vtech, you have to figure out how to wire in one of these-->

If you want VTEC, that's a whole different story...

 

1) B16 is DOHC
2) If you're thinking of the SOHC D16, then yes, the D15 transmission will work.
3) Header should bolt up, but not positive.
