A larger displacement motor will spool any turbo quicker. As far as it being for low end power and no top end, that's up for debate. I would think that cam profiles, any head work, and turbo sizing would be more of a factor in determining the shape of the curve. You'll definitely make more power down low, but I don't think we've seen enough stroked VQ37s to determine if they die off up top.

If I'm remembering correctly the stroker kit from GTM shortens your revolutions. So if you bought a stroker kit, for example and my understanding, and managed to stuff a 71mm turbo down I think its going to need more time to spool up, right? So our cars are what 7300rpm? If its full boost at 6500 hundred and the stroker kit knocks out the revolutions to 7000 rpm, what exactly is the point of a stroker kit? The 71mm turbo will never be fully used. I don't know but thats my understanding of a stroker.

Boring out would increase the revolutions. I see that MORE beneficial. IF IM UNDERSTANDING THIS. Again, I could be talking about of my ***.
