i have a 91.5 and im looking for a better turbo upgrade i hear the 14 cm turbo housing and the 60mm compression fan is the best choice can anyone help me out

 

As far as "upgrading" your stock turbo, yes it's pretty sweet. Just think about how addicted to bombing your truck you are. If you feel you're gonna end up continuing to add hp here and there, you may just want to look for a whole new turbo. If you're content with a little extra power and better ride, this upgrade is great.
I'm happy with it. It spools ALOT faster than stock and makes driving my old girl quite a bit more satisfying. Although I have a few plans up my sleeve and my upgraded H1C is officialy temporary.
Also, I noticed you have the 5 speed, You might want to consider the 12cm exhaust housing(waste-gated). It should compliment your transmission better than the 14cm, if it's waste-gated you can adjust how much boost you want to run.
