How well does the 2.4 header flow? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

We pit the 2.4 vs the OG 2.0 header on the FA20 and tune for both. I think you will find the results revealing and account for some of the issues (aka torque dip) fixed on the 2.4.

awesome info, thanks!

Nice video. However, I can't see a clear comparison between FA20 w/ stock header & stock tune vs. FA20 w/ FA24 header + tuned. Could you post a dyno chart comparing these two?

There still is no tuning solution available for the 2.4 globally. ECUTEK are likely to be the first but you will need to wait unfortunately.

He was asking for the dynochart comparison of the fa20 with OEM header + tune vs fa20 with the 2.4l header + tune so both are with the fa20 engine where tuning software/hardware is available
