In my opinion, there is no Twin-Turbo engine combination on the market that can compete with this engine on a scale of quality, value, and completeness.This is a real street Turbo motor that was designed to cruise at 2000 on the freeway, drive 400 miles in a day, and make 1500hp without breaking a sweat. While still sounding like a Hot Rod. We’ve went to great lengths in development to bring you a cost effective turn-key solution. If you’re looking for a high quality affordable Twin-Turbo engine, this is it.

"On the freeway I leaned into it pretty hard and it felt like an elephant pushing on my back. Then Nelson pulled up next to us and motioned to turn up the boost. We did and the car laid tracks at 70 mph while still pulling like an atlas rocket. I can only imagine what it's like at full song."
