Are you worried about throttle response or spool at low rpm?

 

I'd prefer a little lag for a road race

 

I'd prefer faster spool for better exit speed out of corners and throttle response is actually really good with my AEM and light flywheel!

 

At 5-6000 rpms a gt35 and a gt3071 will build power at about the same rate..

 

But I would prefer to hit power before that range

 

Can you just use a slightly smaller a/r with your current set up?

 

Thats a possibility but I don't need a 750 hp turbo I just want the 500 WHP to hit as soon as possible. If I gotta buy a smaller turbo with a ball bearing thats fine I'm just trying to figure whats the best dependable route(as much as dependable anyways)
