With so many threads about turbo upgrades for RB25's i thought itd be a good idea to start a thread that shows results only, as the results from various threads are scattered everywhere. Everyone has there own ideas about what power they want so obviously there isnt ONE perfect turbo upgrade for everyone.

Please post your RB25 dyno graphs only and state the following:

-Engine management

-Boost ran

-Fuel used (pump or special)

-significant engine mods (eg cams)

The idea of this thread is to be a quick reference to various turbo's performances on RB25's, not to be a discussion thread.

Thanks
