Over winter I'm going to be upgrading the turbo setup on my SC300 and will need someplace local to do some custom IC piping from the TB to IC and IC to turbo outlet. While it's there I'm thinking I should make it legal to 10.0...I know it's hard to quote without seeing exactly what is involved, but if you could let me know ballpark estimates on the following I would appreciate it. Feel free to PM me if you don't want to post publicly. Thanks!

1. Rollcage setup good to 10.0. Hoping to retain stock seats and not have to step over a large door bar. Back seats won't be used so piping can be done however is easiest for you.
2. Custom 3" IC Piping- From tb to fmic and then from fmic to turbo outlet
3. Downpipe- 4" off the exhaust housing down to a 3.5" pipe that will turn down around mid car. Will need bungs for factory o2 and wideband o2.

For reference the car is a '93 Lexus SC300 with the 2JZGE motor with a single 67mm turbo setup on it.
