when you drive a saturn... fabing up your own turbo system is the only option you have LOL. There are several guys on the ion redline forums that fabbed up thier own turbo systems, even a couple that kept the eaton and pieced togeather/fabricated thier own twincharged systems. the origional twincharged ion redline was built back in 2004 before we had any tuning options at all, thier solution was a second fuel rail with an extra set of injectors that were controlled by a secondary fuel system. it was pretty amazing b/c it kept the drivability of stock injectors/fuel system/tune, but was still capable of supplying enough fuel up top.
of course since then larger injectors and tuning solutions have been made available, so thats not how i would go about it today, but it was amazing that sombody pulled it off at the time. between the blower and the turbo i think it was boosting 24 psi, and made some 360-370 fwhp, and about the same torque.
