If you are pushing the limits of your BMW E36 M3, Z3, E39, or E38, you know that spark blowout is the enemy of horsepower. As boost levels rise and fuel mixtures get richer, the aging ignition systems on the M52 and S52 engines often struggle to keep up.

If you are a UZ enthusiast, you already know that the 1UZ non-VVTI is a legendary powerhouse. However, as these engines age, certain OEM parts are becoming harder to find. Specifically, 1UZ non-VVTI oil pumps are no longer available from Toyota, leading many builders to swap in the more abundant 3UZ oil pump.
