righty ho ! ive had to make this decision myself as i bought a vauxhall with imobiliser issues !!! or created them.
basically im buying a set of throttle bodies from a local breaker for £50 plus the vat on friday but im going down to pick my carbs. to go with this i need megasquirt. now looking at all the sites attributed with megasquirt for my engine i have worked out i can run mine with existing sensors from my engine as the vauxhall sensors are "perfect" for megasquirt. for me this works out that i can get my engine RUNNING on megasquirt with the throttle bodies i settle on.
now if you can make a chassis you can make a manifold for throttle bodies im using the std injection rail from my engine and injectors but the spacing issue well its the ISSUE ! there are bike bodies that can be seperated and spaced to suit the inlet ports on your engine thus making or cutting your std manifold easy as the injectors are correctly spaced already.
this link is fantastic for a zetec guide basically the same for all

but there are megasquirt forums you can just google.
for mine it looks that just over £550 all in i can megasquirt on bodies and buy a new acewell digi dash to display all the info i need
im sold on the bodies
