Is it possible maybe for one of the experts on precision turbos to give a sort off matrix about the precsion turbo lineup? The reason I ask this is because all the info is scattered all over, not only that some of it is wrong ... ex:

SC61, makes 600whp, 28psi @6000rpm on B16A, 5500rpm on B18C etc etc ...
SC63, makes 650whp, 28psi @6500rpm on B16A, 6000rpm on B18C etc etc ...

There seems to be very little info on these:

GT32B, GT32E, GT35, GT35B, GT35E, GT35S, GT37-76, GT37-81, GT37, GT37E, GT37S.

For instance I have seen the GT35E advertised as a 600hp turbo vs the SC61 advertised @ 680hp, however I have seen a thread on here that says the GT35E is worth 50hp more than the SC61...

Anyone know all about these things and feels like letting the rest of us know?

Or something like this https://honda-tech.com/zerothread?id=523242
But more geared towards the newer models..

The GT series turbos use ratings taken from the downloadable Garrett catalog, which you can get at http://www.turbobygarrett.com. They are usually very conservative.

I tend to try to make a distinction between peak hp at the crank, peak hp at the flywheel and and actual hp in round town driving at moderate boost levels on pump gas.

Thanks Rod, will check it out ... is there a way to work out spooling ... for instance instead of saying that a turbo will spool up on a B16 at 6000rpm, rather maybe saying it will start spooling at xxxhp or something?
