I want a new turbo but, is it worth it to settle for the 16cm turbine housing? how much lower will the E.G.T. be with the bigger turbine housing? and is there any other advantage with it?

 

I have the same question, also whats the cost of a new housing?

 

Depending on what you're doing with the truck you might not like the slow spool up of the 16. No big deal if you are towing for miles on end on the interstate but not so good in city traffic.
I only ran a 16 for a week before opting for a 14

 

is 14 the stock size on my 98 12valve?

 

Stock is 12cm wastegated. The 16 will be nonwastegated.

 

I have the wastegate disconected rite now, should I just get a 14 then?
