difference between 16g and big 16g and 18g

[96talon4g63]

i picked up 2 turbos last weekend and i was told one was a big 16g and i was wondering where i could get some pics to see if its the real deal. second i picked up an 18g and the only difference that i can see is that it doesnt have the lip inside and bigger ports, how could i tell the difference, or where could i get pics???

The inducer wheel and exducer wheels are the most accurate way to figure it out. The Big 16Gs inducter wheels diameter is 1.89"(48.006mm), and its exducer wheel diameter is 2.68"(68.072mm), I am not sure on the wheel diameters for the 18G. I will keep looking and post when I find them. Also the inducer Diameter on a MHI EVO III 16G is 1.903"(48.3362mm), and the exducer is 2.675"(67.945mm). Here are 2 links, the first is to the 18G with a TD-05 housing>>>http://linux.forcedperformance.net/...oduct_Code=NTDSM18G5H&Category_Code=DSM-Turbo, and the second is to an 18G with a TD-06 housing>>>http://linux.forcedperformance.net/...roduct_Code=NTDSM18G6&Category_Code=DSM-Turbo

No I didn't. Look at both maps side-by-side. They are different.
