Not sure if this is the right place as the Zetec SE is probably more like a Duratec but anyway it's a Zetec do here goes .........
This is my installation of Bike Throttle Bodies on a Puma 1.7 Zetec SE (also OK for the Fiesta, Focus, Puma 1.25/1.4/16 Zetec SE's as well as far as I can tell).
I had originally bought two sets of 2001 Triumph RS sprint throttle bodies (955i Triple engine IIRC) for a Mazda MX6 KLDE engine (aborted project), so when I got the Puma engine for my Anglia I offered up the inlet gasket and to my surprise they were almost mm perfect in both inlet shape and spacing. These throttle bodies are similar to the Jenvey Direct to head ones in that they have a round inlet but an oval outlet and so match the inlet ports on the head well.
As for mounting, as they have an oval exit a flat plate adaptor (10mm ally laser cut) is all that is needed, the throttle bodies are held on with self clinching stainless m6 studs (you could use coutersunk bolts if not), the plate is then held onto the head with countersunk m8 stainless bolts. You need to countersink deep enough so that the bolts rotate with the TB's in place as thy overlap. I also centralised the ports as the approx 1mm difference did not affect the throttle body connections and balance adjustment screws. Note you need to shave off a little bit of the TB mounting lugs as they foul the injector bosses on the engine.
Once fitted I added some full radius trumpets (brake duct ends) from Larkspeed (46mm) which do have a bit of a step but good enough for me, you could blend them in if you really wanted to, and a set of Ramair foam filters.
So, all up I think it has cost me around £150 (2 sets of throttle bodies £70, inlet trumpets £25, filters £25, ally plate £30) with very little work to be done, this is pretty much a bolt on and go solution and hopefully with a decent exhaust will give me around £150hp.
