Thanks to Joel Bowlin( @Silentkiller335i ) who did the footwork here, R&R Torque converters can increase the 6hp21 stall to 3000-3200 for $650. The turn around time is about three weeks and should be daily driver friendly. There will need to be a new stator, rework the fin angle and a high flow turbo mod.

No sir, not lvl 10. Company that is big in domestics has been doing this forever. Just send it in, and they modify it for max stall it can handle, which is 3000-3200. $500 takes about two weeks.

I just want to add one more to the list. TCR is working on mine as we speak. It’s getting the stall increase to 3000.

Sre you hybrid or single? I need to know if 3000 stall can let a non twin scroll build boost

I have a N55 with stg3 twin scroll turbo. I can’t tell yet if that stall is going to be the best for my car because my motor is still getting build. Anyhow, it should help. I’ll report back once I get my car back. Also, if I not mistaken the max stall you can get is a 3200.
