Re: Ford 2.8 / 2.9 v6 swap questions.
The C4 tranny uses the tranny bell from the AL4D if I remember correctly, and the short tail shaft from the E-150 series Ford. The flange on the shaft bolts nearly directly to the stock Zuk shaft, you have to grind the lip of the flange on the Zuk though.
Yes, the 1.6 is easier. But 10 years ago it wasn't. 5 years from now everyone may be dropping the 2.9's? Blah blah blah about breaking this and that and what not. With the hp/torque from the 2.9, you don't need to get on the pedal. Don't get on the pedal, and you won't break it.
And it's nice to have that power on the road when I need it too.
