There are a few different flavors of the 16g
small 16g - usually 340hp
big 16g - usually 350hp
evo16g - - usually 380hp
I have the evo 16g and am pretty happy with it. The smallest amount of boost I can run is about 9psi. It reaches that by 3800-4000rpm and pulls to redline.
I used to have a dsm t25 when my motor was stock. From outside, the turbo looks about the same size as a 16g. look at the compressor wheel and youll see a big difference.
I ran the T25 at about 13 psi on my stock fs motor for about 2 1/2 years with no problem using a safc and larger injectors. The evo 16g pulls way harder at 9psi and is probably safer then the t25 at 13psi. A smaller turbo is going to work alot harder to make the same power as a larger turbo at less psi. In doing so, the smaller turbo will also create tons more heat during compression as well as higher egts.
DSM turbos are cheap. The only problem is getting them to bolt up. If you or someone you know are handy with welding, Id say go for it. Otherwise just save up for the disco potato.
