Hey guys,

At the mo, I'm running a standard 5.0 in my NC on dual fuel. On colder plugs, 8.8mm leads, an Impco 225 mixer and a few other bits and pieces, the car dyno'd at around the 100rwkw mark.

In the VERY near future, I'll be "acquiring" a refreshed motor out of AUII XR8.

The question is...
Will the Impco 225 be good enough to cope? Or will I need to upgrade? If so, what are some recommendations WITHOUT going LPGinjection?

Thanks
Kos

if you can fit impco 425, or alternatively GRA 440-480, etc, might be hard to fit the 425 they are bulky.

would the GRA 440 simply replace the existing throttlebody?

does anyone have any advice on this sort of mod?
