Intake Manifolds

[simplicity05]

Planning on keeping the car N/A for a while, turbo eventually. What would be a good choice for an intake mani?

[scort2498]

a ported stock one from jp.
or a frim.

[SeRiousZX2]

Frim

[2000ZxT]

Focus SVT IM is great choice, yet very hard to come by.

I have one. It may or may not be for sale soon.

[S/R]

guys in the UK are using Rover turbo manifolds with a zetec adapter plate. it seems to work pretty well too. pretty cheap alternitive to the Ford racing manifold

ports are way off, those guys are just nuts. I looked into this, let me see if I can find you pictures of how far the ports are off.... I think one of the runners was off by as much as 1/2 inch...

[Beodude123]

Yeah, pretty much all we have is a ported out stock intake manifold, or a Ford Racing manifold. I haven't seen many with the SVT on there, so I don't know much about that.

[simplicity05]

Can someone post up the ford racing manifold part number please?

[Beodude123]

It's sitting in my garage, but I don't feel like going to look. Maybe tomorrow.

[Spyke-Zee]

sometime this summer ill have my johnP IM for sale. ive got an FRIM now but he needs to do some work on it before it will fit right. drew and i have the old style FRIM, which require modifications. the part # is M-9424-Z20

[ZX2 Sleeper]

Contact zzzx2. He has the new FRIM.

btw, i think i might have my friend Port a stock intake manifold for me. My friend has good skill with stuff like that.

[simplicity05]

That FRIM is teh sex right there! Guess it's worth asking - how hard is it to get an IM on w/o previous experience doing it and what is the aprox. hp increase with this?

[2000ZxT]

The SVT manifold is better than the FRIM imo for anything N/A.

[Thnikkaman]

The SVT manifold is better than the FRIM imo for anything N/A.

not according to this book: http://focus.c-f-m.com/index.asp?PageAction=VIEWPROD&ProdID=139&HS=1

the FRIM will lose some HP in the mid range but will make more power in high end. I would want a FRIM over a SVTF manifold in my NA build. I guess thats why i have one! lol Old Style FRIM represent! it took me a long time to slot the holes, drill and tap the vacuum ports, adapt a mustang throttlebody... good memories.

[2000ZxT]

Or you don't even know about the SVT IM.

It switches to short runners at 6k, and you can set a switch to throw it to the short runners manually.

Of course CFM is going to tell you to go with the $600 manifold......

The ammount of usuable torque and technology behind the SVT manifold makes it well worth a $100ish price tag. Not to mention the angling of the plate where you mount the TB makes the airflow quite a bit more of a direct flow to the IM.

And anyways, N/A modding a Zetec Escort is a proven (again and again) terrible idea...

dude leave this thread, dont go around telling people that modding their cars with bolt ons is a terrible idea. what's wrong with you? why can't you just let people build their cars without your opinion getting in the way. what exactly proves that N/A is a bad idea? i've seen more zetecs blow up on F/I than N/A... so tell me, is it really a bad idea to stay N/A, or are you just caught up in the fact that turbo puts down bigger numbers? grow up...

That's a very bold statement considering that most of the members here are modified N/A.

Right on.

[simplicity05]

Ok, so now that that little pissing contest is out of the way... lol Go away for a day... eeesh

I'm not saying I never ever ever in a million years want to turbo the zx2. If I had the money I'd do it in a heart beat. But fact is that more people have this car and a lack of funds to do what we want than those who can play. So again, back to the question at hand - SVT or FRIM and why? Can anyone talk actual numbers? Even ball park them. If I run either or, are we talking 5-10hp gain, 20-30? 800-1500 (with a few stickers added on my bumper of course)?

P.S. If you can't laugh at part of the last sentence, please don't post calling me a newb....

[2000ZxT]

The SVT IM I have is for a [budget] 180 RWHP N/A Zetec I am building for a kit car...

That's all I'm saying.

[Robend]

check an SVT forum and see which manifolds they're running, that would give you the best idea

[vitaminease]

Does anyone have the FRIM Flow Results in CFM?

[Spyke-Zee]

if anyone does ford racing or johnP might. other than i dont know.

[TTFOWIA]

subscribed.

[HondaStomper]

so 2000Zxt you have a SVT mani on your ZX2... what did you have to mod to make it fit, and how did you controle the runners? I am thinking of picking one up my self...

[Spyke-Zee]

i highly doubt its been installed yet.

[99fordzx2]

Im interested in how its controlled as well, and if there is a way to control the runners automatically.


-D

[Thnikkaman]

you can use an rpm activated switch with the SVTF runner control box. set it to the rpm you want to switch over and you have automatic control. MSD sells many of such switches, http://www.msdignition.com/rpm_7.htm. I have one that controls my nitrous system - MSD digital window switch p/n 8969. works great with the factory DIS system.

[JohnP]

if anyone does ford racing or johnP might. other than i dont know.

Ford has no published flow rates for the ZX3R/Z20 manifolds , nobody at Ford Racing has a clue . Probably the only person would be the engineer that designed it and did the R&D , that engineer recently quit and moved on . You can find HP/TQ figures on line for the manifold ,all the way up to 500HP+ .

I clean up the ports/TB bore of flash and mold seams . The injector boss gets slimed down and the ears cut down that protrude into the port . Both manifolds do not match the head ports . The Z20(old) manifold needs the holes relocated to bring the ports inline with the head , then the head port matched to the manifold . The ZX3R(new)bolts on , but the port still doesn't match the head . The head port needs to be reshaped to match the manifold . I'm working on a ZX2 head and ZX3R manifold at the moment , had to drop the floor and widen the walls to match . Never have flowed one , probably should , if I ever get the time .

There are a lot of variables to come into play with flow rates for manifolds . What kind of head , cams , intake induction , exhaust and TB . You can flow just the manifold and get big numbers , then put everything around it and see what you have , it's not the same thing .

For making big numbers the Ford Racing manifold is the only way to go . It'll run on the street , just comes on a tick later , then will pull to wherever your brave enough to take it .

The stock manifold runs approx. 260 CFM , ported it can run from approx. 275-290 , depends on the port size and TB size , 55MM or 65MM . The ported stock manifolds I do uses a lot of filling to re-shape the plenum throat and runners .

or u could rig it to control it manually. u would have to hit a button or flip a switch ever time u want it to switch but its doable. just run the long runners reg unless ur racing then slip over to the short runners at 5.5k rpms maybe

[JohnP]

The runners in the SVT manifold are spring loaded , without the control hooked up the runners are in the Short position .You could use a locking push-pull choke cable . There is an excellent discussion about using the manifold on Myzx2.com . I have played with the lower manifold , maybe come up with a plenum to use with the short runners.

http://myzx2.com/forums/thread/4546.aspx

Pictures of the SVT manifold ,also pics of a plenum mock-up just to see how it would come together . It wouldn't take a lot to do a plenum for the Lower manifold , give you a nice short runner intake .

[aaronrun]

Anyone know what kind of gains you could expect from a JohnP, FRIM, or SVT IM? My car has intake, header, exhaust already.

[Spyke-Zee]

the gains will vary. im hoping 10-20 on my build. at some point ill have it installed and get another dyno. when i do, ill post the numbers.

[Beodude123]

A ported stock manifold, no matter how good of a job (sorry John) isn't going to give you nearly that much. But a FRIM should bump the power a lot.

[JAX]

Eh, it's a shot in the dark, but Focus Central made IMs for the zetec. Very hard to find, but I got mine off ebay so I know it can be done. It's got short, beefy runners and is constructed of some composite material, and that's about all I can tell ya lol But yeah, I've seen it on a ZX2 before so it is an option if available.

[pissdrunx16]

I seen a so called focus central IM listed on ebay it looked like crap.... I would post the link but its not listed anymore. It might of just been in bad condition?.....

[JAX]

It never was pretty to look at unless someone painted it. It had the look of a chisled piece of charcoal; no attention to asthetic value. If you do find one make sure it has a hole for the IAC valve or you're in for a hassle making it streetable.

[aaronrun]

Anyone know the part number for the new style frim? The new one bolts right up, correct?

[Beodude123]

It will bolt up, but I doubt the intake ports will the same relative size as the runners on the FRIM.

[pissdrunx16]

so is there a decent IM that will mount to probs?

[Beodude123]

Go ask Probe questions on Probe forums...

[Spyke-Zee]

right topic wrong car/engine. ill have to agree with drew on that.

[ChillinZX]

M-9424-ZX3R

There is a guy on Focaljet that sells ford racing parts for 10% over cost. I think his screen name is FORDRACINGPARTS and his name is Steve. Getting it from him is around $610ish, anywhere else is $720+. If JohnP is alive and well next year he should recieve a bunch of expensive goodies from me to port match for my N/A weekend warrior car.

[Stretch]

HI-JACK ALERT! :o

I've been snooping for parts at the "local" wreckers and did a search for intake manifolds. I'm prompted with SOHC and DOHC variants. Okay, ZX2 is a DOHC, no problem, BUT, then it asks for 7-bolt or 9-bolt?!?!??!?!? ("9 bolt mtg to head" and "7 bolt mtg to head")

What? :?

Can anyone shed some light on this for me please? I am new to these cars, but nothing i've read thus far has led me to believe this difference existed. Are there any other differences with stock parts Ford put on these cars through the years?

PATIA!

[JohnP]

Some of the manifolds have 9 sleeved holes ,some have 7 . They all fit the mounting bolt pattern . Some manifolds will have a blank top hole in the middle and one on the bottom . The reason I have never figured out , I have worked on both , thats the only difference .

[Stretch]

And John I thank you once again for your highly valuable input. :)

Now if only an after market assembly wasn't so difficult (read: timely) to procure. :angry:

Dammit here comes that stupid little bug to bite me in the ass again! :( :razz:

[pissdrunx16]

Go ask Probe questions on Probe forums...

I was not commenting on probs!! what i ment was a im that will mount up without any mod or prob..lems haha
