Honda R Series 1.8 SOHC

[420Coupe]

This post is more for any R18's pushing it to its limits.

I was interested in trying to gather any information on Fully built Civic R18, the 1.8 SOHC, as I am currently in the process of building this Platform to the next level. With the Help of Jotech Performance we have been working on this project for a little over a year now and are finishing up Fully building the block with custom head work, valve train, and so forth. I was curious to see if any other R18's out there pushing the platform harder then we are or N/A please inform as I would like to see their progress and exchange useful information.
The last run the car made at the track was 13.5 @ 7.5 psi creating 241 whp /231 wtq and still averaged 40+ mpg on the highway, prior to building we cranked the boost up to 9 psi and it made a huge difference, 276 whp /250wtq very big jump for just increasing boost 1.5 psi which is I decided to fully build this platform.
