hi ive seen a few turbo cars running twin 40s with turbos are they standard carbs or do you have to seal them cus on the net some sites say you do and a few say that you dont have to. and have you got some for sale that are sutible for turbo that are a reasonable price i can pay buy paypal thanks adam
pretty sure the ones for use on turbo engines have sealed throttle spindles, may be difficult to do on non turbos ones.

I think you can put the carbs in a sealed box and balance the air pressure with what the turbo is making. I could be wrong......
yep that would work,
pretty sure some jets/airways need soldering up too, and maybe some drilling out.
is there a specific reason you want to use 40's?
would be a lot simpler with a home made planum, and a single body.

i just want to use carbs ive got a mk2 escort with a 2l pinto in and i dont want to spoil the looks of its so i was thinking turbo it with twin 40s. i
was just thinking that when you open the bonnet it would look right

Ditch the jets and solder the holes up, weld 4 injector bosses on the underside of the runners to the head after the throttle valves (ie out of
sight). put a megasquirt on it and just use the dcoe throttle valves as ITB's
new seals in the throttle shafts should be tight enough to put some boost on <7psi otherwise take them out and put proper bearings in them.
I have seen this on a supercharged honda civic (really old one) once.

There is a discussion of this in Vizard's Mini book.
2 options
1 suck through with standard carbs with obvious effects on mixture heat etc.
2 use dellorto's from Lotus Esprit turbo that were 'specials' for blow through use, or copy the mods from those carbs on to your
standard atmo ones.
A bit pointless using DCOEs this way , Not really a sensible thing to do these days, if you are going to supercharge /Turbo either use fuel injection
or use suck through using a simpler single big carb.
DCOEs are worth money don't butcher them. Either buy suitable throttle bodies or adapt an standard efi intake sytem -- you can even use
manifolds off other engines for example the complete Rover 2 litre M16 Turbo inlet assembly can be fitted to Ford Zetec and CVH heads and can flow
enough air for well over 240 bhp power outputs.

Jus be sure to post pictures if you go this route. that would be some "wolf in sheeps clothes" install
