I think this may be a B16 Del Sol intake manifold? It says P30 on the back. Anyway, there are two coolant nipples in the picture. I know where the big one goes, but what about the little one? I have never seen an intake manifold with that little one.

Thanks.

 

Does it loop through the throttle body?

 

It's definitely a coolant outlet. It looks like hose #3 "Bypass Outlet Hose" attaches to it.

 

#3 goes to the big nipple. Check out my post below with the red lines.

 

don't you mean #6? that looks more acurate

 

goes to #5 in the diagram.

 

Oh okay, now I know how to read those lines... they correspond to the other line with the same angle.

The bottom of hose #5 connects to the nipple. The top of hose #3 connects to the big nipple. Shweet. Never understood those lines before, never had too I guess.

 

Yea it took me a while to read the diagrams but I finally got it to

The first diagram that Rok Stok posted shows that the little nipple on the intake manifold goes to the front of the TB for the FITV, correct?



-------------------
My question now is, that can't be correct I thought the front of the TB for the FITV connects to this water outlet:



-------------------

Just like in the diagram of the 2000 Civic Si:

 

If you try to put the P30 manifold on you're si you're going to find yourself short a line, because you don't have anything to run to the smaller nipple. What I did was get the piece #6 in that middle diagram WITHOUT the nipple and then ran that extra line to the manifold nipple.

Make sense?

 

I think I might have figured it out. I think I need the Del Sol water outlet with the Del Sol Intake Manifold. On the Del Sol, the water source for the FITV is out of the IM, on the Si it comes out of the Water Outlet. If I have the Del Sol IM and the Si Water Outlet I would have two sources for one FITV!! Too many. (This is exactly what Sk8shorty said).

Sk8shorty - #6 (Water Outlet) without the nipple is the Del Sol or ITR piece correct?
