Look at the difference for the money:
Everything in one box using the best quality parts
CARB Legal!
A real electronically controlled secondary fuel system with spark retard, the stock computer operates with no spoofers
Finished hoses with AN hose ends, banjos, or o-ring flange joints
An intake manifold that not only mounts the secondary fuel system but improves performance.
Garrett ball-bearing watercooled turbocharger
Pre-built exhaust manifold-turbocharger-outlet elbow-oil & water hose assembly

Simply the best of everything. E-mail sales@dralleengineering.com for more info
