03 wrx bb500 grimmspeed 27psi speed density 3rd gear pull!

[@shawnsquires2716]

what all is done to it? Also how is the spool time? If you're able to compare how is it compared to stock?

[@SubieMayhem]

It's really strong like I'd say 6 times as strong as stock it starts building spool around 3000rpm and fully spooled by 4200rpm. The wastegate flapper bushings are a bit weak so I wouldn't do any 2step on these turbos. Many things fmic, ethonal sensor speed density, 1050cc injectors fixing to move to 1300cc, 1 step colder plugs, 04 sti transmission, map dccd controller, uppipe downpipe tomi extreme ti exhaust, tein suspension and center roll and bump steer correction, turbo smart bov, many upgrades. I have a iag closed deck 2.5 block I'm getting ready to build as well and will be making a video on
