- ECU and Tuning: $1,000 – $1,500
- Exhaust System: $600 – $1,000 (Kelford)
- Intercooler: $400 – $800
- Miscellaneous (gaskets, belts): $300 – $500
Total Estimated Cost: $7,000 – $11,000
Comparison of Performance and Reliability
Both the 2JZ and RB26 engines are capable of producing 400 HP reliably, but their performance characteristics may differ. The 2JZ is often praised for its linear power delivery and ease of tuning, while the RB26 is known for its high-revving nature and aggressive power band.
Reliability
Reliability is a crucial factor for a daily driver. Both engines have proven track records, but the 2JZ is often considered slightly more robust due to its design and the availability of quality aftermarket parts.
Power Delivery
The power delivery of the 2JZ tends to be smoother, making it more suitable for daily driving. In contrast, the RB26 may provide a more exhilarating driving experience with its quick spool and high-end power.
Aftermarket Support and Parts Availability
Both engines enjoy extensive aftermarket support, but there are some differences in parts availability.
- 2JZ: A wide range of parts from various manufacturers, including Tomei, is readily available.
- RB26: While also well-supported, some parts may be harder to find due to lower production numbers.
Final Thoughts
Choosing between the 2JZ and RB26 for a 400 HP daily driver ultimately comes down to personal preference and budget. Both engines have their strengths and weaknesses, but either choice can lead to an exciting and reliable driving experience.
When considering reputable brands like Tomei and Kelford, it’s essential to factor in the total cost, performance characteristics, and your specific goals for the build. Whichever engine you choose, you’re sure to enjoy the journey of building a powerful daily driver.
