better off using throttle bodies

weegaz22

45's would probably be best, as higher up the rev range when the 16v starts to take off they will be able to give better fuel delivery where as the 40's may feel like they are strangling it high up

cossiecrew

is there anybody that has 45s or 40s on a 2.0 zetec in this club

YOU CANT USE CARBS ON IT MATE

it will fail mots miserably on emmissions and kill the cat very quickly.

you NEED throttle bodies - end of.

obviously you can use them on cars that dont have as strict emmissions tests but not on anything made after 1992.

i have got a set of suzuki GSXR throttle bodies that im gonna fit to my 2.0l zetec,. they need a fair bit of work to get them on tho.

and aslo with t/bs you will need after market management to get rid of the mas air flow sensor.

my mate has a set of GSXR t/bs for sale, £80

well, with 40's less bhp but more low down torque

45's more bhp at max revs but less torque

It's Czech Mate

45's

My mate has a 16i on a 2.0 zetec with 45's and it is superb.
