What do you reckon? Will it work

You'll prbably need a progressive throttle quadrant to make it drivable at low speed.
Unless that is an ultimate spec Zetec with massive valves, cams, all steel bottom end etc. 52mm will be massive overkill, and will likely give you
driveability problems IMO.
The engine that Dave Walker fitted big TB's on was a Duratec that was already developing ~230 ( or was it 250?) bhp.
agree with this
cheers

It's pointless. You will wish you hadn't. I know a guy who had real issues with 48's on a 2 litre zetec. I opted for jenvey 40's over 45's on my old zetec having driven both options. Bigger in this case is definitely not best.
Throttle bodies arrived yisterda morning. They actually taper in from 55mm at the airbox side to 47mm at the injector (dual stage?)
That makes them about the same size as the ports on the ST head....
More parts needed...

Right, its a challenge now... everyone her saya they are too big....
Not according to Burtons, they reckon 48mm for a tuned 2L zetec, so thats me going for it....
May take a long time as its running carbs atm
and I have a set of 43mm jobs as well.
The bodies taper down from 55mm to 47mm. That should accelerate the air and punch it straight down the port. May be a problem whacking open at idle
but that can be over come with a correct setup IMO
STAY TUNED
