Don't listen to this BS. Run 15psi daily on 93pump and your fine, no matter if your running the KKK stage 2 or HKS T51R. Anything more than 15psi, use C-16 race gas to be safe. Thats it, no rocket science involved. Get any turbo you want. Just remember the more power you want, the bigger turbo you'll need, hense a little more lag. The lag issue is blown out too. I've driven a RX7 with the T51R and its not bad at all. In fact, when I do it again, thats the turbo Im getting. Its bad ***.

Correct me if I'm wrong, but I thought the T78 is very comparable to the T-66 from Turbonetics as far as compressor maps.
So, if it's true, then 15psi is just getting into it's efficiency range.
However, remember that 15psi on a T78 flows way more than the twins at 15psi. It'll have less heat since it's less stress on the turbo at the same boost levels.
Like Ernie has stated, you'll be using 15psi for daily driving or what not, but you have the option to crank it up with race gas to get some serious power.
I seriously doubt you're going to run 25psi often to and from work.

Don't take somebody's word for it, go to a dyno and find out for yourself. Taking somebody's opinion is asking for trouble. Doesn't matter how educated we are on the subject, every car is different.
