Mazda MZR 2.3 engines found in: Mazdaspeed 3 6 / Turbo / CX-7 DISI Direct Injected Injection Axela A true cut above in quality and accuracy! You’ll need these tools to positively hold your crank and cams in place whilst timing your motor. No other mfg offers the level of precision found here. This high quality kit features both the cam lock gage, and crank stop TDC pin. Using both of these will allow you to be 100% certain your cam install results in proper timing – failing to do so can have very disastrous results – bent valves, smashed pistons, etc. Gages are much more than a simple piece of bar stock like others have produced – they are much thicker (and hence stronger) bars that feature 2 machined reliefs offering a TIGHT +/- .001” fit.
