Our client came to us looking to make more power out of his true S15 Silvia.  Since this is a very rare car we made sure only the best parts went on this application.  We contacted PeakBoost and had a custom top-mount manifold fabricated utilizing a v-band inlet paired with a 3″ v-band downpipe.  We also contacted Precision Turbo & Engine to have a custom billet turbocharger assembled to our specs with their new line of v-band turbine housings.  For fueling we relied on the Injector Dynamics 1000cc’s after installing the Greddy S15 Intake manifold and converting the fueling to a top-feed injector system.  Paired with the AEM EMS and converting the engine to speed density we were able to fine tune this set-up to 423whp/356tq at 20psi on pump gas. 

(423whp/356tq 20psi) (406whp/339tq 18psi)  (375whp/315tq 16psi)  (317/262 11psi)
