Since its introduction we have been impressed with how well the 370z’s VQ37 responds to simple bolt-on modifications. Steven L’s Solid Red Z34 made some great power gains with intakes, exhaust, pulleys and an UPREV tune from Rob.

Shown above are the Stillen Gen 3 dual intakes, Stillen exhaust system and pulleys.

Before/after with the Stillen exhaust system.

Stillen intakes before/after.  We dyno’d the car before the mods, after and also with the tuning…


With just the bolt-ons Steven’s Z picked up 23hp/9tq to the wheels with gains throughout the entire rev range. Icing on the cake: Rob’s UPREV tuning squeezed even more hp/tq for a grand total of 315hp/251tq!
