ive searched and couldnt find any helpful info w/ the d16z6 mani.... ok i am doing the mpfi conversion on my 91 hatch, with the hoss d15b2 in it. i have a d16z6 intake manifold that i will be putting on the car pretty soon but have a few questions first. My problem is that i do not know where these 4 lines should go. #1 and #2 are off the IAC/EACV, and #3 and #4 im not sure of at all, infact i do not even know what the thing underneath the throttle body is... maybe someone can help me out i think that #2 connects to #3 but im not sure and wanted some extra opinions

I am pretty sure those are all coolant lines. They should receive collant from before the thermostat and return it somewhere after it.

That thing below the TB is the fast idle thermo-valve, it raises the idle when the car is cold. The lines into the IAC do something simliar.

HTH,

thanks, im starting to think that maybe that TB wasnt off a z6 or the mani isnt an actual z6 mani because it doesnt have a map on it... but thanks for being the first one to try and help me
