So I got my manifold on Firday...prostreet

i have a question though.. The manifold i recieved has two coolant lines, one big one and a small one comming out from the big one...(when mounted its on the passanger side of the manifold) does anyone know what i do with that small one?
My '01 GSR only has one line....



Ps i know id figure it out when i install it but...i just want to know before hand thanks

its for the coolant line that runs to the throttle body

Your GSR one is probably T'd before the large inlet. The small line runs to your throttle body to keep the butterfly from seizing up in cold temps.

Hmmm....i guess ill have to look at it myself when i get home....anyone have a close up pic of it already mounted?

You'll just have to run a small hose from that small barb to the small barb on the bottom/front of your throttle body. But if you really live in the "land of 115 degree weather", you could probably live with just blocking off both of the holes.

Hmm wonder if there will be an ramifications (SP?) on doing this?

Nope, most people bypass their throttlebodies, I did on my car and there's no problem with it. Unless you live up inside the Arctic circle you won't have a problem with your TB freezing.

actually that nipple is for the factory oil cooler

What? factory oil cooler? I thought only the b16's came with that...and since this is a gsr manifold....it wouldn't apply...so therefore it leads me to beleive what 90% of the other people said and that its for the throttle body.
