PHASE 2 - New 034EFI T3/T61 Turbo in 516whp configuration,: (Spring 2005) - The upgrade of simply the turbo results in an additional 100 wheel HP and a much peakier power band.

PHASE 3 - 034EFI Garrett GT40R Turbo, 034EFI High Output Intake Manifold, 034EFI Production Tube Header, 599.1whp (Fall 2005), 640whp Spring 2006.

PHASE 4 - 034EFI Garrett GT42Rs Turbo, 4"-3.5" downpipe, -10AN fuel feed line, dual 044 Motorsport Fuel pumps(January 2007). This phase is developed for 1000 wheel HP or approximately 1300 crank HP which is what this turbo is capable of, stay tuned!
Update! - I baselined the current head with the new turbo to the tune of 703whp at almost 40psi boost, the next step will be to install a new 034Motorsport high flow cylinder head with oversize valves, solid lifters and CAT cams, this head flows 50% more than the current head and should bring output to the 1000whp range desired, stay tuned!

After some "developmental sorting out" (read the Motorgeek Forum thread for more detailed info), and dyno tuning and street tuning, the results have been quite spectacular, and its only just the beginning.

Stay tuned for more updates about this powerful 20vturbo motor. Future plans include an 034Motorsport solid lifter head that will flow 250cfm and rev to 9500rpm. 800+ wheel HP (or over 1000 crank HP) and sub 11 sec. 1/4 miles' are in the foreseeable future for this motor.
