Ive heard that the 2.5 is better for turboing due to the thicker walls? But I understand having a bigger engine to get more power. Still need to research for myself, but I have seen that posted somewhere on the forum I believe.

 

I think I may have posted that or quoted that from Steve Martinez (Exile Racing).

 

I'm not sure how much thicker the walls are as some one is running the 2.5 heads on the 3.0 block ... if there was a difference I'd doubt that would work

 

I believe that is correct silver. wasnt intending to steal thunder anywhere...

I'll have to look for it and quote it, but I think Steve said the difference wasn't huge, but thicker is thicker. If you think about it, the 6g73 is basically a bored out 6g72. It made sense to me when Steve brought it to light and it stuck.

That would be where you said the 2.5 walls are thicker.

 

Good find bud. I wish I had quoted Steve on that one. As you can see that was in 2006 and Steve had been saying that for some time before then.
