Key features:
Dyno proven models featuring many variations to achieve best all around performance( not just top end RPM ). Units are equal length, and equal bend for proper balance between rotors. Tapered runner design, only slightly oversized from OEM. Does not hurt throttle response or bottom end/midrange performance. 
6 injector for semi pport, 4 for side port ( Billet 8AN fuel rail included with purchase).  Does not work with other fuel rails, as the fuel injector location has been changed for better fuel delivery. 
All oem emissions removed( for off road use only**) FC water passage removed.
LIM flange o-ringed( between UIM/LIM)
Mounting tabs for heat-shields
Properly clears all of our corresponding Cast EWG FC Turbo System. Will not work with our IWG FC turbo systems. 
This FC lower intake manifold shares the S6 flange between the UIM & LIM. You can use the OEM FD3S UIM, or the Turblown UIM model. 
OEM turbo coolant feed port is  removed from FC LIM; no coolant will be flowing through LIM like stock. Coolant feed will have to be pulled from rear iron or water pump housing. 
LIM will NOT work with off the shelf fuel rails, as we have changed the injector positions for optimum spray pattern position.  We do sell optional 48mm dummy injectors for those who do not want to run every injector position.  Fuel rail is for 14MM upper and lower o rings only 48mm total length Injector Dynamics injectors. No press in sleeves required. We have not checked fitment with the OEM FC turbos. 
8AN ORB fuel rail does not come with AN adapters, or Pulsation dampner. Fuel rail does not require 8AN lines, one can use 8AN ORB to 6AN adapters. 
Dummy injector blanks available for those who do not want to run all injectors.
Supplied with all necessary mounting hardware.
If you have a stockport, bridgeport, or streetported engine you need the sideport model.
