I was speaking of the compressor exducer, and turbine inducer.Scott is correct, RCC Turbos has used a .48 a/r turbine housing on our stage 1 and 2 kits for over 15 years now. Also the Garrett 50 trim we use is actually a 54/56 turbo size wise. A 76/64 as Rob mentioned is typically rated for over 1000hp, a GT35R is only a 61/62
Is the T04 50 trim GT series??The GTX turbos do not spool quicker than the original GT series, where are you reading about how quick they spool?

The official Garrett site.
As for the spool i have heard many tuners on car ie VW to say this abt the spool but i understand it is not the same on every type of engine..that is why on a VW you may see close to rated HP but on a busa there is big diff between declared and actual hp..
Had anyone used gen 2 on a busa?
turbine side is the same, the compressor side is modified. Same spool.
Slightly is a good word, since it is really hard to notice . . . but if you take a look at the Rocketman thread (ROCKET MAN | Powerhouse Motorcycles) you will see the difference between a GT35R and a GTX35R . . . basically 100+ more to the rear wheel . . .Typically a billet wheel is heavier than a cast wheel so spool time is slightly later, not sooner,
