RT Throttle body conversion

Hi there,

Does anyone know how to fit a laguna throttle body (1.8 8v spi) to an RT 1.4 Clio engine? Do I need any wires from the laguna engine bay?

Cheers
Dan

I've just sourced a throttle body and injector, along with the 'odd-shaped plastic tubing' (technical description!) to the air-box.

Attempting to fit it to my 1.4 energy engine as soon as it arrives.

The Laguna TB has 3 bolts, as does my inlet manifold.

I'll have to find a conical filter from somewhere, and open up my inlet a bit, but no... No wires are required for me...

If you want, I'll post up my adventures as soon as it's done.

Okay this is what happened -

1st attempt:
Installed complete assembly - top and bottom half and the idle motor My throttle-pot multi-plug didn't fit... The one on the throttle body had less pins (4) versus the 7 or 8 on the car... So I left it off for the time being. Fired the car up and it redlined. I don't know why. Panicked and switched it off.

2nd attempt:
Installed the lower half of the throttle body, using my original top-half and injector and my original idle motor. Idled perfectly. Still not got the throttle-pot plug on. The car seemed to drive smoother, but attempting full-throttle acceleration resulted in a total loss of power - as if I had a vacuum leak somewhere along the way.

3rd attempt:
Still using the laguna bottom half, but now using my original top-half with the laguna injector. Also hack-sawed off the throttle-pots from both bodies, and used my original pot on the laguna body. Throttle-pot now plugged in.

It idles high, but I reduced it a bit with the screw on the back of the throttle-butterfly.

The car does seem to 'drive' a bit better - but it's running rich and idling at around 1050rpm when warm.

More testing and meddling around to follow.



If anyone has more information on the throttle-pot, and what it ACTUALLY does on the energy engine, please post here.
