An Unexpected Power Enterprise Build

Several months ago, one of our customers had a recently purchased 350Z with the Power Enterprise TT kit that unexpectedly decided to let go on him soon after purchasing. Rather than giving up on it, he decided to let us work through the issues and make him some more power in the meantime.

Upon picking the car up, we soon noticed that the Power Enterprise manifolds and turbos would need to be replaced at the very least. In addition, several years of rust from the salt and snow along the coast had taken a toll on his engine bay and engine itself.

We decided to go with brand new Power enterprise manifolds and turbos, an Injected Performance Stage 1 short block, and fresh heads with upgraded valvetrain. Many other items were replaced with brand new components as well, including a powdercoated front engine cover and Power Enterprise air filters.

Our customer wanted to continue using his UTEC for engine management, and several maps were created for different power levels and exhaust setups. At the time, a stock-like exhaust was still installed on the car. This severely limited the amount of power to be made. Disconnecting the exhaust yielded major gains, and showed more than enough evidence for our customer to decide on a larger and more free-flowing exhaust. The dyno chart below shows a before and after with his original exhaust and then removing the restrictive piping.

After a thorough re-build, our customer was happy to receive his refreshed 350Z. He is now enjoying a very responsive and reliable Power Enterprise kit that is surely lots of fun on the street. We used our motorhome and fully enclosed trailer to deliver the car back on a beautiful Monday morning.
