If it's a street car why not go N/A or supercharger at most, imo turbo's are only a headache to suffer if you need the power. Packaging, heat management, tuning, etc. are all inherent problems that a N/A street engine won't have nearly as much of. Go LS, get 550 ultra reliable hp for way less $ and still have way more power available than you will ever use on the street.

I have big blocks, small blocks, twin turbo small block, LS supercharged etc. I been there done that. Go with a LS based engine. Better design all around and will be much easier to sell in the future. Kurt Urban did my twin turbo smallblock in the Mule. I would recommend Kurt or Brian Thomson http://www.thomsonautomotive.com/?page=about.cfm

Brian is who built Stielow's engine in the red Devil and can build a LS engine to suit you. He knows what it takes to make them hold up. He and Kurt will both give you real dyno #'s not just made up magazine #'s

I agree. Kurt is great.
