First off to the users i was an *** too i apologize. I have a issue that i just need a helping hand with. I have swapped a d15b1 for a d16y7. The engine is in but having issues with what intake to use. As the forums ive read a conversion to mpfi is better but i dont have the money at the moment to get that intake. Soon i will but for now i need help with either using the y7 intake or the b1 intake. If i use the y7 intake then none of the electric plugs will work because they are different. If i use the b1 intake i cant figure out the vaccuum. Which in time i can research that but suggestions are welcome. The build car is a 1991 hatch. The donor car is a 2000 civic

 

you the stock intake for the chassis.

 

Ok thank you. Would u have a good place for me to find the vaccuum line diagram so i can connect all the coreect hoses to the apprpriate spot.

 

What car? what sub model?

Best bet is to search for a factory service manual for you car... It will have a diagram in there. Post a Pic and I'll tell you what goes where.

 

1991 hatch car engine d16y7 with d15b1 intake. Ill post a picture after work today. I found a couple diagrams last night that i think will help me. Gonna print those off too and take with me to use as reference.

 

You have to use the d15B1 manifold if you are not swapping to MPFI.

The vacuum connections are exactly the same as before you did the swap.

 

I figured my vacuum lines not. Now to the wires. I should have some plugs left that dont connect to anything right. Or do i need to use the plugs from the other harness to make it work

 

A picture is attached for viewing. You will see the tube that is open in the bottom of the picture i found where it goes. But there is(looks like) 2 egr vavles on the back of the intake. 1 of those lines is connected to where it needs to be which is also in the picture the other one that u cant really see is underneath that vavle that should have a vacuum line from it. I dont know if i can t 2 of those lines togeother and make it work or research the entire car again to see if i have missed something. I have raised the car up on a lift and looked at every nook and cranny but cant seem to find out where it leads.

 

the one without a hose on it goes to you're brake booster. FYI make sure you have the hose on properly. mark the other lines you're talking about.

 

Ill get another picture of it today after work and point to the line. I have all my plugs connected except a few that dont have a place. Should be firing it up today i hope ...
