Carbed 7m?

Isphius · 07-01-2006, 03:50 PM

I was just wondering...has anyone ever tried a carb set up on a toyota FI 6 cyl, Like the 7m ge motor? It is a big upgrade on the 80s fuel injected porsches and things like that, In both power and throttle response. The only real hard part i can see is making the distributor advane, Youd would need a controller for it because its electronic. Unless an older 6cyl distributor will fit. Id also raise the compression a little bit, to like 10:1, And i think you vould easily make 250-260hp out of the 7mge this way. And then id like to put all of this in a mk2 supra or an old celica, like a 76. Itd be cool as hell haha.

I personally always thought the 7mge would be a strong engine with three 2 barrell side drafts. 3 pairs of 45 DCOE's, but I think you would have to make your own manifold. Much better than the 2 SU's on the old 240Z's. Oh well...........

LoL people with carbs want to convert to FI and now you want to go back in time? Why?

For an NA motor, The supras FI isnt really all that good for making power, Because of the small throttle body and things like that. Plus its complicated to tune and get running right with other engine mods. Carbs adjust themselves for the most part, By dumping in fuel for a given ammount of air. And most people just want FI because they dont know how to tune carbs and for the fuel economy. A porsche flat 6 converted to carbs from the early FI picks up a lot of torque, some hps, And a lot of throttle response. Im sure you could modify the fuel injection to do the same, But just bolting on some mikuni or webber carbs would be a lot easier. Plus...it would just be cool. haha. Thats my reason for anythin.

They do put out more fuel, but EFI's produce more balance of air and fuel, which is what u want. I would be interested to see what a carbed 7m would be like...
