Different size s366's????

Hey fellas,

I’m putting another motor together for a friend and he will also be jumping up to a 366. We went to order it and he brought up a great question. What is the difference between the ones listed as 91/79 vs 66/74? The 91/79 states a 91.4 exducer and 66 inducer on the compressor side. A 80 mm inducer and 73 exducer on the turbine side.

The 66/74 labeled turbo is the same for the compressor, but the numbers are flipped on the listing for the exducer and inducer on the turbine side… 73mm inducer and 80 mm exducer. I’m not sure if it’s a listing error or not, but we just want to make sure to order the right one for the truck. Does someone want to explain?

Both are .91 A/R Twin scroll Turbos

Thanks in advance!

cmon turbo wizards...school a newb here. This should be fairly easy to answer, or maybe irrelevant... They are listed different from many different companies and ebay listings as well.

Here is a 66/74

Here is a 91/79

What the hell is the difference?

That sure helped. I'd assume from what was stated, he will want to go with the larger trim turbo.
