d15b or y8
 

ok so i feel kinda dumb to ask but i need to know how can i tell(or can u) if a head is a d15b or a y8?:confused:

Which D15B?

We figured it out its a po8-1 so its a vtec jdm d15b we are putting it on a jdm d15b block

We have done the swap ran into a few issues. Its throwing a code 21.. vtec solenoid not 100% sure what's wrong :-(
