Just an MBC Manual Boost Controller.
I didn't use an AFR guage , just kept winding it up bit by bit.....the rods are fine, don't believe the scarey stories about chocolate rods, but DO get an AFR guage....
The larger diameter aluminium tube from turbo to big intercooler (GP Racing on eboi) using their piping/silicon tube general selection kit that comes with all sorts of bends and clamps was fun to use to pipe up to the throttle body, a proper final silicon reducer with IAC valve offtake from Samco was used at the TB itself, I believe all the extra air volume and higher boost made it great, you may want R/T5 injectors to be sure. Green tops were over the top for this, it ran poorly.
Plans for air to water to air intercooler in place of battery to give direct shot at TB and very short charge hoses were shelved as the above setup was so much fun around town. An oil cooler on the auto was going on but I got a nicer V70T5 auto instead, I missed the low down torque of the 2.4 greatly.
