I am going to upgrade soon, should I go all out with 12 or play it safe with a 14, I still have the stock turbo on my 91.5. What king of horsepower gain can I expect?

Thanks

I was advised by "wannadiesel" to go with the 12cm ex housing! I've never regretted it.

Look at the truck in my signature....I've even towed a 30' 5th wheel with the 12 on the truck!

Good luck

Thank you for your quick reply TJE, I am seriously considering the 12.

I went with a 12cm waste gated when I revamped my turbo with the gds kit

If Stock injectors on your 91.5 I recommend a 12CM 100%. You would also benefit from a MWE SLOT on that cold side when you increase your drive pressure/low end boost.

With Stock injectors and the 5-speed the 12 is really nice. Won't increase peak HP but it will drive much better and feel much stronger at the bottom of the RPM range because you won't be waiting for spool. If you get into some really big injectors you'll need a bigger housing but you will likely be going to a different turbo at that piont anyway.
