the TD05H series for EVo-1, 2, or 3 all run 7cm turbine housings. The only diff is EVo-3 which has a larger Compressor wheel exducer, which is why it's called a 'large' 16G, but the inducer for all Evo-1,2,3 are the same, which is 48mm.
The other diiff is..Evo-3 (49178-01470) has a slightly thinner and lighter turbine housing. Which is why most ppl look for the E3 turbo's...but turbine wheel for all Evo's are the same.

if u port n fit in a 16g fin then it will be a diffrent story
porting n fitting in a 16g , i would rather get a td05 16g from a vr4 which has a smaller backside than evo's for quicker spool
