hey guys, i picked up my 99 GSR motor (going into a 94 dx). i was inspecting the motor when i noticed this funny looking canister that sits under the intake manifold.

it has a couple vacuum lines running to it. one runs to that funny thing on the side of the manifold.

what the hell is all that stuff for, i dont think my dx harness has a plug for that.

can some one please explain. :roll:

someone told me it controls the butterflys in the intake mani.... whats that all about?

yes it does control your butterflies. you will need to wire that in.
 
There's a similar system on the 1.8L Escort GTs. There are 4 butterfly valves in the intake manifold which are held closed by the vacuum pressure. At 5500 rpm vacuum is released from the canister and the butterfly valves open to allow more air to continue on to the 7000 rpm redline. The system Mazda (yes Mazda built the 1.8L) called it was VICS, Variable Inertia Charge System.

I didn't know the GSR had a similar system to this. :)
 
I have a B16 so I really don't know,

but I do know the gsr's have a 2 stage IM and the butterflys open at a certin rpm, and I believe these butterflys are controlled by a vaccum source as well as the ecu, I believe you will have to wire the control directly to the ecu if it the thing you are talking about is in fact for the secondary butterflies

c-speedracing.com has a gsr swap write-up that shows you how to do it with pics, check it out, also reference section of this site is good for pin outs

thats exactly how it works on the GSR except the open point for the GSR is at 5750-5800 rpms
 
or you could just take them out. friend of mine with a 96 b18c1 in a 94 hatch did it...works just fine.
 
yeah and then you lose the variable length intake manifold- which would be counterproductive, don't ya think?
<_<

Sweet!

Some of you guys think the Escort engines are pieces...Mazda has been using this technology since 1990 when the 1.8 DOHC was born...and probably earlier in the dohc 1.6s. :D

What's the first year Acura put that system on the GSR?
 
the first gsr was in 92, but i dont think the b17s (1rst gen gsr) had it. i think its 94 or 95 and up on the b18's but dont quote me on that.

94
 
he ran a 14.4 last night on a stock b18c on street tires, with just header/intake.


seems fine to me.

Maybe someone should do a little reading about variable length intake manifolds- Yeah it's great that he ran a 14.4, but he could knock off a tenth or two by using the manifold the way it's designed-
 
the gsr mani can only be used on the gsr. this is the one head in the b-series that has non interchangable parts. The two stage mani is gsr exclusive. IMO, honda was trying to expand on it's vtec system, but it's obvoiusly not the greatest design, otherwise honda would have used it for the type r. For a b16, the cheapest manifold upgrade I'd buy would be a type r mani, or if you are going for all out top end hp gains, skunk2 and jg edelbrock victorx are good. I heard endyn has a Carbon Fiber manifold, but it's super pricey.
