I have read numorous turbo threads and I am just starting to understand the actual size differences of turbo. However does anyone know the actual size of our stock turbos? (measurements) Just want to compare actual numbers so I can see the difference between stock,towing, and race setups.

thanks

 

Do a search on here. They have been listed before. I just don't remember what they were.

 

IIRC for the 04.5-07 HE351 it's 60/60/9

Okay great, thanks. Wow, I didn't realize the stock turbo was that much smaller then the aftermarkets.

 

When comparing turbos, it is not best to simply compare wheel size. There are many differences that come through with even same size wheels...

You must compare using a map.

 

HE351 60\65\9 is the actual sizes. The 9 cm^3 housing is also misleading as it is a single volute not split. It flows comparable to the older 12 cm^3 housings.
