First of all, the Honda GC engine is their consumer grade unit- their commercial grade engines all start with GX. Both of these units come with the consumer grade engine. Feature for feature they appear to be a match. It looks like the "T" version could be a special edition they made for a warehouse store. The handle angles look a little different- but that could also be the way the photos were taken. We work very hard to make sure what you see online is exactly what you get in the box delivered to your door- so if you order from us, you will get the black engine cover. The other thing to remember is that you won't pay shipping or sales tax when you order from us. (Sales tax is charged on Illinois orders, since our warehouse is in Chicago.) Thank you for your interest in Pressure Washers Direct!
