I am in the middle of doing the DPFI to MPFI conversion, using the complete manifold from D15B7 from a EG coupe. Here is some pictures : -



Blue arrow shows the hose that I don't know where to connect.....



Blue arrow shows the same hose as picture above. Red arrow shows that the other pipe from IACV connected to the bottom on the TB.

I have referred to a B-series car, they seems to connect the blue arrow pointed hose to the metal pipe that runs along side the block at the back, and there is a barb fitting to connect this hose. However on the D15B2 there is no barb fitting there to connect. Hence any pointers where I can route this?

Nice to see you here Matt... Bump for help........ Can anyone point out if the blue arrow pointed line is the inlet or outlet line for the IACV?

As I am considering spliting the rubber hose that connects between the Intake Manfold flange (next to the 180 degree bigger hose) to the barb fitting next to the water line under the intake manifold. Would this work anyone?

the one coming from the long black tub that runs the back of the motor is were the coolant comes from into the intake, atleast it built pressure when i blocked it of for awhile on another car i was working on

Ok I think this picture would explain the problem a bit better : -



See the red arrow is point, (I don't mean the rubber hose) I mean to point at that black metal tube that runs along the block.... these is no barb fitting there to take the hose from the IACV.

Now see where the blue arrow is pointed, It is now connected to the manifold, hence i am wondering if I use a T piece there and connect the hose from the IACV would that be ok? (Note the second IACV hose is currently connected to the bottom of the TB).
