Kaxe,

Now that DRM motorsport have there throttle body kit out i am thinking that the NA route might be back on again.. ;-)

What put me off last time was having to ditch the OEM cluster, new ecu, new pedal box etc..

With the DRM kit, you retain the fly by wire throttle.

With a ric wood head and some custom cams, then the ST could be a real flyer on the NA route.

The big issue with the duratec lump is the fact that the cams and crank are not keyed.. this means that in our engines, if you rev past 7300 rpm, there is a real chance that the crank pulley or the cam sprokets might come loose/off..

With these components key'd plus some rods and pistons, then 9000 rpm is a real possability, this is where the throttle bodies really start to make some power..

So it's options, options again.. LOL
