ok well i have read a bunch about upgraded turbos and such, but for 500hp daily drivin and sometimes pulling, the silverbullet turbo which is similer to the sps66. seems to be the one to go with,

where do you buys these darn things? and any other suggestions thanks

 

I personally have the SPS62, I daily drive with 550-600 hp, and I tow a 12000-13000 pound f'ver, and have never had a problem with my egt's!!!!

 

I think a 62 will be a much better daily driver than a 66 and will support 500+hp.

 

I just ditched stock turbo 4 a hitechturbo htb2ss and I love it no lag lights up great claim it will handle 425-550 upgradable to

 

my sps62/14 supports 500+hp, is daily driven very easily, and tows 10K lbs like a dream
