here is some pictures and information for R1 carbs that i put onto my c20xe

this is what the carbs look like the fuel inlet is in the middle underneath the carbs.

the best fuel pump to use is the r1 pump, it has a built in regulator. when you are wiring in the pump
make sure you dont mix up the wires because the pump will burn out! the earth is the black wire.

you will need to get a manifold made, these can be got off boggs brothers, i made my own manifold

you will need a altanator adjusting bracket, i made my own one

the main jets need to be drilled out to 1.8mm for a c20xe these are the middle jets.

for the ignition set up you can use a mk2 cavalier ignition set up or megajolt setup which is what i used.

if you use megajolt you will have to move the new coil up so the plug leads will reach. i modified the old one

to connect the carbs to the manifold i used 42mm water pipe and jubliee clips

i just blanked off the water ways, the manifold and carbs never really get warm so it still runs fine

may i add, a cheaper way to spark zetecs would be the e.s.c module from early fiesta 1.1 a this is similar to ford edis. vauxhall probally read off a different number but if they dont then its a cheap way
