We typically use a "reverse split" style camshaft on turbo setups, meaning intake duration is larger than exhaust.
However, what size cam you want/need will depend on your driveability requirements. We tend to go a little conservative on turbo cams because you don't need a big one to make big power. That's what the boost is for.

The 239/232 looks good, but all those cams have way too much lift IMO. It's not necessary to run that much lift especially with the added risk of valvetrain stability issues under boost.
No one is going to be able to help you unless you spell out what you want from the car. Driveability? Desired idle speed? Desired power levels? Desired power curve? Worried about service intervals and spring changes? Etc.
Camshafts should be chosen based on a large combination of reasons. Not because it was the best looking one in the catalog.

That is why I'm seeking advise on it and prefer someone with results from a similar cam similar build. As far as idle 800-900 rpm with some lope its mostly street driven with some 1/4 mile passes if I find time! Power goals are 1000whp or a bit more but most of the time it will be dialed down. I would prefer a cam with gentler lobes so I don't have to mess with parts very often plus it will see maybe 1500 a year. Power range I would like to make power from 3k to around 7k that should help with narrowing it down I think and its a Auto stall with come after the cam is picked to suit it!
