S14 ITB - DCOE airhorns

[Lee]

Who needs that? Probably nobody. But hey, I had to make them. So, I will probably run these just for the fun of running them on the S14.

[Grover]

Lee. In theory could this set-up be used on an E12 head and utilize MegaSquirt, sort of a replacement to the TWM system?

[Lee]

It could. But interfacing the ITBs to the M10 head might prove a lot of work, but nothing impossible. The ITBs have the proper 100mm spacing, same as M10 bore spacing. ITBs can be purchasd for $200-$250 per set, which is 1/3 of TWM prices. Plus you get the fuel rail and pressure regulator for $30, versus $300 for TWM.

Basically, you get an S14 set-up for a lot less than TWM. But you must fabricate the intake flange, which can prove difficult.

[Grover]

Since we're just talking pipe dreams here... Are you basically saying that the bolt pattern on the intake side of the E12 head is simply not compatible with the holes of the S14 manifold? Or am I missing something else?

[RSwannabe12]

I'd like to get a set of these with alpha N so I could run without without the air flow meter.

Is there anything from them preventing someone from using a Alpina carb aribox then? Hmmmmm.....

Exact. Very different.

Kinda like this?

schnittle,

Any chance you have a drawing of that flange?

Kinda like this?

Yup. And a lot of work too.

i bought this kit on ebay a few days ago, has anyone successfully installed S14 ITBs on an M10 before?

[Lee]

Hi B.

Congratulation in your purchase. The main problem you will face is hwo to seal between the plate and the S14 ITBs. Originally there was a very thick rubber gasket. In your case, you might want to fabricate some rubber gaskets.

Thanks, Lee! I've made paper gaskets before but never rubber, how would I go about making something like that? I was hoping to find someone that has this setup installed on their M10 that could help me figure out what I need.

Lee,

How much for the air horns? I have this setup now from B, I was thinking of finding an o-ring large enough to cover the area and have the grooves machined on the flange side. This may work for the sealing of the itb's to the plate.

[Lee]

It will be cheaper to make some thick gaskets.

I don't sell the airhorns, just the adapters.

They are $45/pair.
