Hi guys.

New to the world and looking to upgrade the BA turbo.

Anyone currently running a 6466 or a 6766 on a lowmount setup. Any results on dyno/track? Any big difference in ball bearing vs journal bearing power wise? (I am aware there is a $1k difference in price!)

I have a low mount 6466 on my car. You have to modify your dump a little and cap off your water lines not a big deal at all. It starts spooling around 2000rpm. Don't waste your money on a 6 boost gate turbo and plumbing- you won't get to much change from $5000. Buy the bolt on 6466 from rotor master, use the internal gate and the 1.07 rear housing, $2699. I'm running in my car at the moment so once it's run in ad had a power tune I'll give you an update.

If people aren't seeing more than 500rwkw I don't see why you would go such are large frame turbo when smaller frame GTX, efr, MTA, are doing upwards of that on stdanifold? Just my 0.02
