With my setup (DRAG Comp, Smarty, stock injectors) what would the best option for a bigger turbo be?? and at what point do i need to get head studs or O-rings??

 

I think this question is a personal oppinion thing. You can upgrade to the BD Super B and it will handle what you have now and more. or you could get a larger exhaust housing and use your exsisting compressor. You could even do twins. Its all about how much farther you want to go and what you expect from your truck.
Headwork should start when you get into higher boost psi. Its best to do it when you want to than when you have to.

How much does one of those cost??

 

The Super Stock 62 can be had for $1400....more for stainless housing. I will second that suggestion.....great turbo!

 

Where did you find the Super Stock 62 for that? PDW has the Street Stock 62 (HTB2) for $1439, but the HT71-62 is another $140 on that. Stainless housing is $300 more.
