The primary difference lies in the cylinder head. VVTi engines have a variable valve timing mechanism on the intake camshaft, requiring specific camshafts, cam gears, and cylinder head components. Ensure you purchase parts designated for your specific head type.
Q3: Is it cheaper to buy a full engine package or source parts individually?
This can vary. Full packages often offer a slight discount due to bulk purchasing and curated compatibility. However, if you find specific deals on individual high-quality parts, it can sometimes be more economical to build your own kit, provided you have the expertise to select compatible items.
Q4: Where can I find parts for a milder 2JZ build (e.g., 500-600hp)?
The same specialist suppliers will offer components for milder builds. You might look at packages labelled "900hp" (as mentioned by Goleby's) which often have more conservative, yet still robust, internals suitable for your target. Focus on upgraded injectors, fuel pump, a good turbo, exhaust, and potentially forged pistons and rods.
Q5: Are there any common weak points in the 2JZ that I should upgrade regardless of power goals?
The stock oil pump can be a weak point under extreme stress. Upgrading to a unit with billet gears is a common and recommended modification even for moderate builds. Water pumps and timing belts should also be replaced with quality units during any major engine work.
