Message	Great comparison! I would like to cut one up & take some measurements, but its cost prohibitive currently. From what I have seen it look like: Plenum Volume R35>/=Z32 (R35 taller, but shorter on length) TBs R35>Z32 (60 vs 52) Runner Length Z32>R35 (Z32 is nearly 19" long) Runner Cross section @ Plenum Chamber Z32>R35 (Z32 is roughly 2.5" ID) Lower Plenum Cross Section R35>Z32 Valve Diameter R35>Z32 (R35 I37 & E32 , Z32 I34.0 & E29.5) Piston Diameter R35>Z32 (95.5 vs 87.0, allows for bigger valves & less shrouding) Take into consideration the R35 has more displacement, higher compression, newer technology, etc. ~Induetime~ "Lag Less" First Stock Turbo to break 500WHP on boost alone (Pre-E85).
