VICS manifold from 2.0 on a 1.8

[Rubberspoiler]

Hi. I'm going to post this under the 2.0 forum, because it seems there are more activity, and because it is relevant relevant for 2.0 engines.

Is it correct that the VICS manifold is controlled by the ECU??

Anyways. I have the FP-DE and no VICS manifold. Am I able to use the VICS manifold on my 1.8 FP?? What would "activate" it?

I didn't really have any luck with the search function, but maybe I'm just not good enough.

Thanks

the ECU controls operation the VICS butterflies, so it won't work on the FP. according to protegeFAQ.net, the manifold should bolt up. you would be better off getting a JDM FS-ZE intake manifold.

The FS-ZE manifold's only bonus is the extra resonator.

VICS is controlled by the ECU via a simple solenoid that controls a vacuum-actuated mechanism. You could probably jerry-rig a VTEC controller or another rpm-switch to run it.

Hmmm. Thats a bit disapointing. Was hoping it was some kind of vacuum control. Like the VICS on the FE3 and the BP (vacuum solenoid). Maybe that could be fixed togeather with the FS manifold somehow??? Or are those ALSO connected to the ECU in some way?

The VICS seems like a nice manifold. But I'm not sure how easy it would be to find a FS-ZE intake manifold here...

Thanks for the replys so far.

the valves themselves are vaccum controlled, but the ECU operates the solenoids. Like niky said, you could install an independent rpm activated device to operate the solenoid, it runs off 12 volts. if you have a standalone with a programmable output you could use that too. if it's a 12 volt output you can wire it directly, if not you would need to use a relay.

BAM! here you go, http://www.summitracing.com/parts/SUM-830449-1/ comes preset to 5,000RPM which is close to stock i believe.

Don't let you confuse. I'm trying the same over here in Germany, just come over and I'll show you the manifold disassembled. I already transplanted an DE throttle body. The advantage of DE and ZE-IM over the 01 is a switchable resonance tune which improves torque in midrange with the VICS. It's basically a set of flaps opening a passage connection. They are operated with a vacuum actuator, but this is switched on/off with a vacuum switch. (Some also have VCTS flaps you wanna get rid of, only for cold start emissions)

Operating the switch is quite easy, either manually or with an rpm switch (hint: lots of scooter tuners sell it for adjustable switch rpm for a couple of €)

But if you are after serious power, go for a 626GF-IM, which has larger diameter runners (but loses torque in midrange).

Thanks for all the great info. It is really appreciated.

Thanks for the info Cougar. Sounds promising

I am pretty confident in how the VICS works.
How it works
But the electronics are a bit difficult.

What I would like to know, is what should be done to assemble it properly and fix the butterfly screws properly.

@ Pighunter
That does sounds like an tempting offer, but I think finding the time can be a problem. Do you have any pictures of it?

What is hard finding a VICS manifold in Germany??
Its seems to me it is only found on the 136 hp mazda 626 2.0. I haven't had that much luck finding such one here at the scrapyards. Where di you find yours?

 

[Pighunter]

Thats an interesting question. I bought it off a user in the forum and got it via USPS from USA. Even this way is probably easier than to a) find one in europe and b) seduct a scrapyard guy to sell it without the engine.

If you wanna try to find it locally, it is also in the 323 BJ with the 2.0l FS Engine around 99-2001 I think. In case you find one, I would like to have its head ;-)

I knew that, but the 323 Sport are very hard to find. Even more as used scrap car.

But I'll note it down.
I'm on a lockout (nothing critical) for a 1.8 FP head, from a 323, myself. I need the cams to be send to DBILAS for regrinding. Its seems they have a profile for the FP-DE cams. And apparently, it HAVE to be from the 323, since the cams are different than those from the 626 FP-DE (114 vs. 90 HP). Its a bit easier to find the 323 1.8, but scrap yards here are murder to deal with.


Thanks for the info, though. I will try and locate the VICS manifold in the US.
