170 vs. 225

Talking to people on the / board, they said that the 170 shorter stroke would probably be better with a turbo. I hadnt thought about that in my looking. I know my duster was a factory 225 with a 3spd. I was going that way for that reason.

Can someone give me pros and cons to boosting each motor? Obviously the 170 could use Smaller turbo, which might give me a few more choices in turbo. Other than that whats everyones input?

Thanks in advance,
Mat
