3.0 EFI intake manifold modified for a 2.2 head

It's not for a GT in this case, it's for a wagon. I honestly don't know if it fits under the hood of a GT, as I don't have a GT with a 2.2/2.4 head installed to test fit anyway.

I used a Ford TB because it's cheap, it's bigger, and it has a new TPS.

I don't know if it's any use but I have a cut down 3litre plenum in my GT and I'm also using a 2.2 head, so I have the raised ports too.

I decided to cut off the back two runners, no probs with clearance and am using a 3litre throttle body. I'll be going to a mapable ecu over the winter months to get better drivability, but put it this when she's going......she flys

I haven't had time yet, but I do have a 2.2 intake and a 2.2 head and the new 3.0e intake, I will be measuring everything and posting the results. I did check the highest point of the 3.0e intake and a rough eyeball measurement puts it 8 1/4" above the dowel pins in the head.

Is it just me, or am I the only one that's having trouble finding a 3.0 FI manifold to modify? Uwe sent one for a 2.5/2.8 before I knew the difference, but it has the same port size as the 2.2 FI manifold . . . smaller than the 3.0 and the 2.4 (too tall for GT).

If anyone wants a 3litre manifold just give me the nod.......that's why us guys on this side of the pond are useful to know

[baz]

mark they are thin on the ground up north i have been looking for some for folks for a while ,think i've looked in just about every junk yard for 50 miles around me so far

[tomking]

Well mark I would want one and I thank you very much. Let me know how the search goes.

Found a Dismantler with seven Omegas down here in Christchurch - but will only sell the complete motors - with out the ECU - and wants over $1,500 for each of them. Told him he was MAD!
The last WHOLE Senator I got for $800 - on the road and running!

Form an orderly...as the saying goes it's not what you know but who you know......I know a guys who's big in Senators and Carltons, I'm sure I can get my hand or 1 or 10.....let me know guys and I'll get some prices includinging postage (that's the killer, but worth it)

Measured the 3.0e manifold tonight against the 2.2 manifold. No way the rear four runners will work, it will have to be the front four. As I stated above the 3.0e measures 8 1/4" at the highest point above the rear dowel pin. The 2.2 manifold measures 7 1/16" above the rear dowel pin. If you locate where the dowel pin hole is to be drilled in the center two runners of the 3.0 manifold it measures 7 5/8" to the highest point, but it will also protrude further into the hood lip, which I already modified to fit the 2.2, but it now may have to be modified again. So as you can see, the 3.0 is 9/16" higher even if you use the front 4 runners. Unfortunately my body is now at the body shop and I can't test fit anything anymore. If in fact I have to modify the body again to fit this manifold I will be chopping into it after it is finish painted.

Regardless, I would still like one for my long-term, roller cam 2.4 in my GT. I'll deal with the fitment issues once I have it in hand. Thanks for the measured info, 'markandson' . . .

Id' be interested in one as well, though it will be fitted to a Manta rather than a GT. I have a set of twin manifolds and water neck (dBilas) for the 2.2/2.4 heads that I'll be looking to sell if this works out. I REALLY prefer the idea of putting EFI on rather than twin carbs.

I have a 2.4 intake that I got from RallyBob that I now do not need if anyone is interested. I know it will not fit under the hood of a GT but I don't know about the Manta. I also checked another measurement tonight. A 1.9 intake, modified to fit the raised ports of the 2.2 head with a 32/36 Weber sitting on it measures 7 5/8" from the dowel pin center to the top of the chrome air filter cover. This measurement matches exactly the 7 5/8 stated in my post above, which means there is no question that the front 4 runners will have to be used and that it will also fit under the hood. The only question that remains is whether or not the hood lip will need modification. I know RallyBob has stated in the past that there are several different intake heights for the 1.9's I don't know if I have a high one or a low one. I also did not have any kind of spacer between the carb and the intake when it was installed in the car. I only know that it fit.

[GTJIM]

Is it possible to lower the engine a bit by packing between the engine mounting cross member and the underbody of the car? A few 1/2" ( or 12mm!) thick spacer washers down there may give just that bit of clearance needed ...... just a thought ....

[neuropel]

Thanks for the offer, but I already have a 2.4 intake as well. Perhaps someone else can use it though. Mine came on my 2.4 (I bought direct from Germany and the seller threw in some extras). The 3.0 modification looks to be easier than what would be needed for the 2.4, plus it has the larger throttle body (I believe). I'm wanting to go with a megasquirt controller (I have the roller rockers as well). I originally liked the idea of running some weber side draft throttle body "replacements" but the 3.0 manifold trick caught my eye over a year ago. Too bad they appear to be constructed of "unobtainium". I unfortunately don't have the fabrication skills that you and many others on here have so I'm at the mercy of what I can either do myself (limited) or pay a machine shop to do ($$$). Now if someone on here wants to barter some top notch brain surgery on a rat or monkey in exchange for some fabrication work, I'm all ears!! Don't worry, I won't hold my breath...

Be sure to take lots of pics of the application you're working on. I can't wait to hear how it performs.

Just wondering, without a GT to try it on myself, if the normal angle of the motor in a GT could be increases some to allow the 2.4 maifold to clear better? Maybe angling the motor over a bit more with new motor mount(s) would be as feasable as the manifold? Just thinking with my fingers.

[markandson]

The 3.0 intake that I have came with a throttle body but it has the switch style throttle position sensor, not a variable resistor (pot) style. What I am planning on doing is using the TPS from the 2.4 intake that I got from Bob and put it on the 3.0 throttle body. I have checked and the shaft size is the same, but the 3.0 shaft is longer and the mounting holes are in different locations for it to operate properly. The fix is to make a 1/4" thick plate that mounts to the original holes in the throttle body and then drill new ones in the plate to mount the TPS. Both the 2.4 and the 3.0 throttle bodies seem to rotate through the same number of degrees from closed to full throttle so this modification should work.

Yes, the engine can be lowered a Bunch by spacing the mounting crossmember as Jim described. The crossmember can also be "leaned" back some by moving the holes in the tunnel/firewall. ( You have to move them anyway after lowering the mount) This moves the engine back a bit, makes it possible to use the long oil filter, it won't touch the suspension crossmember. There's a few other things affected by this, more to do for sure... There just may be enough reasons to do this that make it worthwhile.

Don't ask why I just happen to know this, OK? My car is completely stock, really!

[markandson]

The 2.4 manifold is extremely high compared to the others. I will measure it and post that measurement using the same reference as I have for the others.
