I noticed there was a heater hose on the dpfi that runs from the intake near the thermostat to the bottom side of the tb/injection unit. I dont see where to route that large hose from the mpfi? Does the motor come with a different water neck and that nipple go to the heater hose or am I missing something?

 

If I'm understanding/following what you are saying, you are talking about #6 on the DX/STD (DPFI) side of the diagram. You need #7 on the Si (MPFI) side of the diagram or some sort of rigged substitute. The water neck/thermostat housing is the same but the hose should be a "U" and connect right next to the cylinder #4 intake runner.

 

thats exactly what i needed. ill be at work shortly so Ill be able to see it in person thanks!

 

No worries

PS
Usually when I need a quick diagram I go to www.thehondapartsstore.com (you can use any similar website). They use exploded diagrams but you have to dig around to find the one you need.
