The Rx6 is a ball bearing turbo; with a good portjob and 18lbs as well as efficient plumbing and what not you should be able to reach your goal of 450rwhp. This turbo will be at 15lbs by 3300rpm's it hits just as fast as stock twins and feels fanf@%kingtastic at 18 or 19. I have been in alot of 7's and I have yet to ride in one that responds this good.Poweraxel(moderator;) ) has had just about every single kit there is including this kit and he will tell you the same thing you can't beat it for the street.:D I also have to agree with above It would be very hard to find a streetable turbo that give you 450rwhp at 15lbs;)

Anyone know if you can get just the turbo from apex or do u have 2 get the kit?? I perfer 2 make my own kit and dont want 2 have to order stuff that the kit already comes with b/c i dont like it. If not anyone know what the response of a T-66 BB 1.15 AR P Trim?

You can buy the RX6 turbo from apexi by itself but it's really expensive-over $2000. Same thing with the HKS turbos.

I do have the KKK (stage2) from SR. Its not ballbearing, but does spool extremely fast. Im very happy with it.
Another option that will give you mega power is the new Greddy T-88 w/ the ballbearing option.
