Turbocharger must be under hood. See drawing for maximum turbocharger size. LINK HERE Turbocharger must have a restrictor plate 1/4 inch thick with a hole no larger than 2.8" in diameter to be measured 2" from the compressor wheel blade. All air must go through the 2.8 turbo inlet restrictor plate. No oval or oblong shaped holes permitted! There must be only one turbo going through one pressure stage. No welding to the turbine housing will be allowed. Exhaust housing to be a T-4 series base.

This is from the interstate website pro farm rules.
