BEP 60-1 or 50 trim?

[4g63t Power]

OK... I was litteraly a day away from buying a 50 trim... When I saw this site http://www.theturbotrader.com/product_info.php?products_id=167 offering various BEP turbos for awesome prices. Since it is so much cheaper im leaning towards a BEP 60-1. I can get the 60-1 with an internal wastegate for 725 as apposed to a BEP 50 trim for 825 from slowboy. I just need to know how streetable a 60-1 is. Approx. where would I see full boost on a stock motor (rebuilt motor and head with 5k stock internals)? Both turbos are favorites of the dsm community and its a tough choice, especially being the bigger one is 100 bucks cheaper. This car is my daily driver and ide like to be around 400hp. Let me know what you guys would do in my situation. I have all supporting mods to run either turbo but would like to still tune with my S-AFC.
Thanks, Ryan

I can get the 60-1 with an internal wastegate

If its with in your budget I'd recomend getting an external wastegate. I was using the bep internal gate with my hx35 and had boost creep issues up to 28psi. Also since switching over to an exeternal gate my already fast spool times have greatly sped up. With the internal gate I was getting 25psi at 3800 rpm's, now with the external I'm getting 25psi at 3300 rpm's.
