The Stage 4 kit, nicknamed "The FAT twins", is expected towards the end of the summer of 2005. Preliminary estimates are 2 GTR30 Turbo's, 1 Tial Sport BOV, 2 Tial 38mm Wastegates and 1 monster Intercooler.

Price on the kit is estimated at $7500. Please contact us for more information about this kit. We will be posting some more information in the coming months including pictures, dyno charts and system specifications.

*All of our kits contain everything to Turbo Charge your vehicle. The only thing that the customer would have to supply is a minimum of a 2 1/2 inch exhaust system from the catalytic converter and back as the factory exhaust is much too small for Turbo applications.
