carbureted commodore v6??

Could you perhaps use a remapped ecu, just tell it to ignore the fuel mixture tables? So long as the crank angle sensor is still on the engine it should know how fast its spinning and where in its rotation its up to, right?

Carb a Holden V6

Triple down draught Webers!! :yeah:

Anything is possible.. just not "bolt-on" for many good reasons.

#1 - It comes factory EFI...

#2 - EFI is good and easily tuned.

#3 - A dizzy? :hmmm: why ditch the direct fire ignition? it's worlds better than a dizzy. GM spent moonbeams developing DFI. It's more accurate and carries alot more current - better spark, better bang!

#4 - why not just get a Chev V6 or a dirty old 308 they carb and dizzy standard :rofl2:

Having made those points clear, if you did carb but stayed with the Delco to control the DFI, the Fuel tables can stay, as "fuel" in the ecu wouldn't be used. Just leave the injector wires unconnected.
You would have to use the MAP sensor connected into the manifold for load reference (tapped into all six runners for Webers) and a TPS on a Carbs throttle shaft so ecu knows throttle position (idle, back off & WOT)..
Change fuel pump to low pressure/high flow or reduce pressure of stock efi pump with a regulator.

Jet and tune to suit! :spot on:

that manifold wont fit and you wont find one that does LOL have to custom make one out of a stocker manifold and a carb plate made of alloy welded on top like the speedway guys do

I just seen the buick in the original post.... Didnt realise it was for a ecotec....

 

[delcowizzid]

wont fit buick either they are all different thats for old buick not any of the engines in a commodore

 

[IMCRZY]

Well there u go then....
