Carbureted 7mge?
 

hey everybody,

has anyone ever seen a carbureted 7mge, or tried it themselves? Please let me know, because I am interested in trying it. I want a carbureted high compression toyota engine for my 1981 celica, and I'm wondering what options I have, if any.

Sounds a little wild ,if you were dead set on that route you might be better off looking for an engine that came carburate.But one option that looks promising is a stroker kit.

What is our Stroker Kit?
It's 6.5mm more stroke that when added to the increased bore equals 665cc more cubes of usable power!
Our stroker kit increases torque as much as 30% and 45 Horse Power (much more can be achieved with other HP increasing accessories). This means more pulling and launching power. This can be used with factory FI or Turbos (adjustments in fuel supply may be needed).

That's the first one I seen ,you may need to search around in case it can be had cheaper ,but it sounds about like what your looing for.

this might jus me
but leave the 7m alone
its an engine of its own
if its going to be modded
mod it the right way
dont molest it

If I were doing an '81 Celica, I drop in a V6. There's enough room in the engine compartment. You could build it up easily. Use the 4 or 5 sp tranny for that motor (ford, GM, etc).

etc etc

so basically, there are no toyota engines that are/can be carbureted that are worth the effort?

It would be realtivley easy to carb an n/a 7m motor, Because it has a distributor. Just tuning it and getting it to run perfect would be hard, because noones ever done it before. I think the 7m with some webber carbs and a header/exhaust could make a nice 260 hp while keeping it stock compression and cams and all that, Plus whatever other bolt ons you can get. The only problem I can see ATM, Is you have no way to advance the ignition timing. The ECU does that, But your getting rid of the ECU along with the whole FI. You have 3 options. 1. you could get a digital ignition that hooks up to an rpm sensor or a vaccum sensor to run your ignition timing, WHich would also be a nice upgrade. 2. you could possibly have someone make you a control module for the stock distributor. 3. And i also think the 5mge had a vaccum advance distributor, So if you could fit that whole distributor or the guts in the 7m distributor, you have yourself a winner. I would say get the swap accomomplished, Get the 7m motor in the celica and get it running in FI mode, With the ECU/wiring harness just sitting outside. The work on swapping it to carbs. I think you only need about 350-450 cfm worth of carb to get it goin, And theres a few you could get. 6 mikuni slide bores on a common manifold to each cylinder would would be nice lol, If you could afford it. Slide bore = 0 restriction at WOT. hehe.

I am currently in the process of getting a ITB'd 7M underway.
I just pulled the 7MGE out of my parts car this weekend, and cleanup will commence soon. I'm not sure if I'm going to run it as an injected ITB setup, or carbed. From what I've found, it's going to cost just about the same either way, and I'd rather run a Megasquirt and some Hayabusa throttle bodies than some weber/dellorto/solex carbs in side draught for the sheer reasoning that I can drive the car and won't have to worry about elevation changes.

For a simple setup, carbs are the way to go.
For a more reliable setup, FI is without a doubt the way to go.

supra2nr: There's no need for that, who said anything about molesting a 7M? I think it's a creative approach to modding, just because it's not what you're used to seeing doesn't mean it's a bad idea.
Variety is the spice of life. An ITB 7M would be amazing...
