Convert Efi To Carb

[Guest Kieran]

How easy (difficult) is it to convert the efi engine managment to run carbs?

 

I am now reaising the limitations with the efi injection system reguards tuning, (it doesnt like lumpy cams and the inlet plenum chamber doesnt flow air very well)

 

I have a 38 dgas carb, wot else do I need?? Would a distributer from a cortina be better than ther engine mangement given to the carbed sierras??

 

Regards

Hi Kieran

I run a 38DGAS, FR32 cam & big inlet valve head.

I couldn't for the life of me get the ESC 11 system to run properly, or

the second earlier electronic unit from a scrappy to run either.

I gave up & bought a Bosch distributor from a 2.0 Cortina/Capri,

with points & condensor, which runs a treat. It may cost a few HP

but it has still run 135 bhp on a rolling road.

I havent had to touch it in 5000 miles last year.

I carry a spare set of points & a condensor for backup.

You need a big base Weber manifold from an early Sierra, which had the

Weber DGAV fitted. The DGAS has the same bolt spacing.

KISS always works for me...

Cheers, Bob

Agree with the above. If you want to get fancy then replacing the points with after market electronic ignition and a 'sports' coil is worth it in smoothness, drivability, reliability and possibly a horse or two at the top end.
