How about bike throttle bodies?
Suzuki GSXR 600/700 (the latest models have 8 injectors!!) or Kawasaki ZX6R
Cheaper and dedicated throttle bodies & more power than the fiesta EFI.
Especialy if you use the 8 injectors - 4 for stationary/low ref & all 8 when
power is needed.

I would mate
But im running a carburettor LOL
I just wanted to know that im not way too rich or lean
Some nice looking products on that website though and im one step
closer if I do want to go EFI since I now have an oxygen sensor
already plumbed in.
Best regards

Have you considered using a MegaSquirt for ECU?http://www.msextra.com
orhttp://www.bs-autotune.nl/pics/KdFi/kdFi20V1320English.pdf exactly the
same as a Megasquirt 2 but a cheaper version.
With it you can tune your engine to what it can give.
It integrates the AFR, water/air temp sensors, MAP, TPC etc. and you can
than tune/optimise the injection time, ingnition specs etc.

i loosely wired up the AFR gauge into the rover to get a baseline
setting, also handy as I'm using a rover / Bosch sensor too
after driving the rover for a week I've concluded that its taught me
not a great deal ;)
well that's not strictly true but i found out no matter what i do to
the car i can not get the gauge to step into the "normal range" with
it just sitting at the end of the lean scale (no wonder its got no
power )
all wired in

so after wiring it into the gauge i was happy to see it sitting to the
end of the normal range towards the rich during cruising
[IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01745.jpg[/IMG]
a little richer under more acceleration
[IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01746.jpg[/IMG]
and lean on the over run
[IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01743.jpg[/IMG]
this is pretty much spot on, especially since its a narrow band AFR
gauge and sensor so its not detecting anything way out either end of
the scale, so for a first attempt at carb jetting its spot on
other things I've noted though is it goes haywire with the choke out
and can go lean at WOT before the fueling catches up as the revs rise,
ill either need to change the pump jet or accept that a carb is still
hit and miss at best.
I've a matching vac gauge to go in next to it tomorrow so i should get
a good idea as to what the engine is up to.
other news, I've replaced the stat for a lower one, but first the stat
housing looked a bit shabby

[IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01734.jpg[/IMG]
so i blasted it

[IMG]http://i120.photobucket.com/albums/o192/jindal/DSC01736.jpg[/IMG]
like new
painted the hose ends with tick polyurethane paint to prevent pitting
and seal some old minor pits

engine seems a touch cooler now so smiles all round
