  2. MHI Turbo Reliability

    Hey guys, I have a 2020 civic SI and I am considering the MHI Turbo upgrade as it fits all my needs. I am currently running TSP Stage 1 with a PRL Stage 1 Intake.

  7. Is this Hondata ECU re-flash for the 1.5T (L15B7) a real thing?

    Here is the link: http://www.vtec.net/news/news-item?news_item_id=1284152 They say it costs $295 and gives the L15B7 an extra 25 to 28 HP, works best with 91 octane instead of regular and doesn't impact fuel economy. That much power is "hidden" in the same exact engine with the stock...

  9. Connecting rod measurements?

    Are there any internal measurements for the 1.5T yet? Specifically I'm looking for rod length, since bore and stroke are already known (73.0mm x 89.4mm, respectively). I'm curious to know what the rod-to-stroke ratio is.
