Single vs twin turbo on an LS2 From my understanding, the advantages a twin turbo system has over a single is:
-less lag
-more efficient for V engines like an LS
-easier to fit in engine bay (apparently there isnt always room for a big single)
advantages of a big single being:
-easier to maintain
-more torque
-cheaper
-more max power?
I was wondering if a big single turbo might be better for more of a drag racing application. The turbo lag isnt a big issue since i would want to daily drive it without going into boost every time i change lanes, and at a strip it would be screaming at 6k rpm the whole time. Thoughts?

Are you building it yourself?
I think I have actually decided to go single. I do my own systems & I think I have decided to do a log set-up mounting the turbo on the drivers side. I decided this for two main reasons; I want easy plug access & I want to easily retain my A/C.
Looks like if I relocate the module down by the frame & go to a different coolant tank & hose routing there should be enough room to run a 3.5" downpipe under the header.

Thats funny you say that. I am building a single, but now, I wish I would have done a twin build. I know the GTO's are a tight fit, and actually, so is a S10. The problem I have, is on a single, fitting a crossover. The crossover is best suited in the front on my configuration. The problem is, the steering box, shaft and accessories are in the way. If I had done twins, the piping would go out toward the fenders on each side, and the downpipe would go almost where the exhaust is normally on my swap.
I also want to maintain A/C, and so based on that, I can not run my crossover under the back, because then on a single, there is no room for a downpipe with the A/C box and the crossover, so actually, there is more room with twins. I did not know that at the time of purchasing parts, or I would have planned better. Sometimes you just don't know, what you don't know.
