So did the swap put my dpfi on the b7 to get it going. Everything went fine motor started up. But as we were topping off the water it came pooring out the back driver side of the block.... Look like there was a extra house out the b7 for something just don't know what.... Searched around about the swap but didn't see any info on this.

 

I have exactly the same setup in my car. You just need to put a short piece of hose on that nipple and put a plug in the other end of the hose. It went to some parts on the MPFI manifold.

Also you need to hook up the fan switch differently. On the D15B2 it is in the block near the oil pressure switch. On the D15B7 it is on the thermostat housing (my D15B7 has a hole for the old location, but it was not tapped for the switch to screw in). Extend your harness wires from where the old switch was over to the new one on the thermostat housing.

 

Ok so put a cap on that. And so when I do the mpfi swap I'll be useing it agen correct?

When it comes to the fan switch we did that but the fan don't kick on. Does the fan only kick on at high heat? And I'm wondering if my car even has a thermo in it to be honest. When u start it cold takes for ever to warm up. Once it does the min u start moving temp gage just falls to nothing... Stop light will go to half mark then stops and don't go higher...

 

Sounds like the thermostat, if you have one, is not working right.

The fan won't come on normally until the after car has been idling for quite a while. The sensor detects the temperature of the coolant leaving the radiator, so the whole radiator has to heat up before the fan will come on. In the old location on the D15B2 it was driven only by engine temperature.
