One thing is for certain that the Ls/Vtec has a long stroke than a stock GSR.

Another fact is that the stock Ls/Vtec (stock ls bottom end with stick GSR head) will make more hp than a stock gsr.

Now, of course, the main variable will be the build quality, so we could say that more often than not, a gsr will be more reliable than a Ls/Vtec, especially in the high RPMs which honda's have been known to make substantial power.

So, with the original question answered above, the nexxt question is undoubtably somewhere along the lines of this:

"Which setup will make the most power, the cheapest way, while maintaining reliability?"

...exhibit "A"

Fast + Realiable = Expensive
Fast + Cheap = Not Reliable
Cheap + Reliable = Slow... eerrr something like that. ... don't quote me.

The moral of the story, kiddies, is this:

With the right amount of money, you can make power with almost anything.
The reason that the LS/Vtec was created wasn't because some honda owner sat down 13 years ago and worked out the schematics of an LS motor and concluded that they would have an increased displacement over a GSR by 1.97% by using a GSR head on a B18B block...

It was more along the lines of this...:

"Damnn Dude, I'm broke as helll, but I wanna faster motor. Sheit... I got this GSR head laying around, and I head that if you throw in on my ls it'll be quick."

...and VUWALA! The poor-man's-GSR was born.

So, if yoru like me, and you don't have deep pockets, and you wanna your civc or integra to keep up... Go for the ls/vtec. But beware... budget builds aren't garunteed for anything...

just my

^best bit of information i found in this thread, great point man.
