Why dual turbos?

What size turbos will you be running?

I would think that for a rally vehicle you would want power all the way across the rpm range and not just up top at high speeds. Are you concerned at all with turbo lag?

I would think a super charger would be a better application for rallying.

What about the suspension? What cha got goin on there?

Either way, good luck with the project and I hope it all works out. Do post pics of the progress as you go along so we can all admire them
