We offer 5 stages of SPORT CAMS performance VCT camshafts for 2.0L/2.5L Mazda and 2.5L Ford Duratec engines (6 tooth cam trigger). These cams cover a wide range of applications from mild pump gas bolt-on equipped engines up to wild all-out high rpm track terrors!
Stage 1 cams are for unopened 2L & 2.5L n/a engines and also work extremely well in turbo engines
Stage 2 cams work well in unopened Hot-Street 2L & 2.5L n/a engines
Stage 3 cams are similar in duration to Stage 2 but require aftermarket pistons with deeper valve reliefs.
Stage 4 cams for high compression street engines that have aftermarket pistons with deeper valve reliefs
Stage 5 cams are for racecars with 12:1 compression or higher.
*** Stage 1 & 2 cams are can be run with the OEM valvesprings. Stage 3 through 5 require our valvespring kit found here: SPORT CAMS Ti Retainer Valvespring Kit ***
During back to back dyno testing on a mild 2.5L Ford Duratec street engine we logged the following gains:
Stage 1 SPORT CAMS gained +19hp & 18ft.lbs
Stage 2 SPORT CAMS gained +27hp & 15ft.lbs
Stage 3 SPORT CAMS gained +29hp & 13ft.lbs
At no point above 3600rpm did the SPORT CAMS make less power than OEM cams, and in addition to the huge gains across the middle part of the powerband, at 7200rpm the cams gained:
Stage 1 SPORT CAMS gained +18hp!
Stage 2 SPORT CAMS gained +35hp!
