MX-5 2.0 vs 2.5 Swap — Dyno Comparison

Dyno comparison between a stock 2.0 MX-5 and a tuned 2.5L swap configuration. Both vehicles tested under the same conditions to demonstrate real-world performance gains.

2.5L Swap Configuration

  • 2.5L Duratec engine swap
  • Stock camshafts
  • 42mm performance headers
  • Full 63.5mm exhaust system
  • Custom dyno calibration by DMS Tuned

Dyno Results Overview

The first dyno plot represents the stock 2.0 engine. The second plot shows the tuned 2.5L swap. The difference in torque delivery and mid-range power is immediately visible. The 2.5L platform provides significantly stronger low and mid-range response, making it a substantial upgrade for both street and track applications.
