How much for a recon one of these for a MY97 Uk 2000

And what sort of power whould it take?

Please

 

You would possibly need to change the rear diff in this conversion.
The box will suffer under high torque not power, but mine has tolerated 360 lbft easy under drag starts (over 140 of them) and 5 years of racing.

You could do worse than talk to David at Welcome to the API website

Tell him '911' sent you. He will advise your options.
