I have a GA16 engine sitting in my lock up. I'll bolt the TB on to mine and see how it runs if you wish?
Could give you an estimated 0-60 before and after, idling issues, setting up issues etc.
If you get no other responses that is.

apparently they run crap, altough i dont know so myself.
you need to have it mapped for it to run ok iirc.

If your car doesnt have NATS fitted. the throttle body will be great with the 1.6 ecu
Thanks people, keep the info coming please. Reason for asking we have a new engine being built for the wide track rally car, 1348cc block with a distributor head. We are using the inlet manifold from the CGA engine with 1.8 Primera injectors. I assumed the old style mass air flow meter would fit but the fuel rail gets in the way so I'm looking into an alternative and the GA16 unit is my best bet. The car will be remapped and I think I have found away around air bleed idle adjustment.
The other advantage is it has a bigger throttle valve. Has anyone removed part of the inside of the air flow meter just leaving the hot wire pick up in place? Just a thought..

I think Matt's still using the Pectel ecu from the good old NME days Ed. I'm not sure what it's capabilities are.....
I did run a GA16 throttlebody on a CG13 engine once. Setting up the idle wasn't too much of a problem without the AAC valve. With regard to the fuel rail being in the way, I modified the throttle hanger to clear the injectors and did away with the idle control all together, (removed and blanked it off). the car however was never mapped to take advantage of this, so no gains were proven. If you are using a later inlet manifold with top feed fuel injectors, then this could be another issue.
With regard to the hotwire pickup on the standard CG engines, cutting the element down, if that's what you mean Matt, renders it pretty useless. The MAF bar is hollow and air flows directly through and around the element.....there's a small gap for air bleed between the plastic unit and the throttlebody wall.
I don't know what the gains of this are for most of the MSC who run a standard engine, but I would imagine the sort of power you are pushing, 140hp, it would be worth persuing.
Ecu wise, that's why I got Ed to order me an Omex, so I can take any tack I like with regard to MAF, MAP or Alpha-N mapping.

what does nats have to do with it?

has anyone got pictures and how to,s for modding the micra harness to use with 1.6 tb....
you know that valve, that controls the fast Idle, if you unbolt that whole unit, (not just the solonoid but the other part too, and stick a plate over it and seal it. then you have to connect up the water system to the side pipe. its near this plunger thing below the throttle. that should get round it

No it wouldn't!
A re-map would be the ideal solution for changing the TB. The GA16 ECU is designed to work with a whole GA16 engine.
Having a CG with GA TB along with the 1.6 ECU would not be ideal
Worked fine for me.

certainly not ideal, but done before !

Thanks everyone for the feed back. I will first try the GA throttle body on its own in a standard (well nearly standard) Micra and work from there to see what happens. I need to get moving as the replacement engine has arrived and needs fitting and running in before it gets mapped.

will the needle valve fit from a carb or has it to be home made.....
na this is just a bolt, look under the bonnet of any Ga16 Primera, and some of the TB's will have a bolt and some of them will have this electronic valve thing. if you can find the bolt then you are sorted.

you see the solonoid with the purple plug. that is the bit you are trying to replace with a bolt. if you see any primeras with a bolt where that thing is then get the bolt.

cool what about the rest of wireing as plugs are not the same are they...wouldnt care the other one i left had the bolt in there
as far as i know the other wireing is all there you just have to splice the plugs on
I've got the same TB as shown on the picture above. You say replace the purple solonoid with a bolt. The only thing left is the brown plug.... But this one has only 2 wires, as the idle connector on my CG13 has a 5 wire-connector.
How do you connect this? And how will the idle run? Soon I'll put Emanage inside the car. I guess this will make modifications as this a lot more simpel.

i think the 1.6 t/b uses ( 2 wire ) solenoids for idle control, and the CG, s use a ( 3 wire ) stepper motor (it looks to me like the pink is the +v feed, and the other 2 are neg (-) signal wires from the ecu) this is why i cut mine off and have a knob on the dash .
if your e-manage has no alternative idle control, you could maybe attach the CG idle stepper motor/valve to the 1.6 t/b (either directly, or remotely, via a pipe)
