All joking aside. I think with the upgraded 17s by adding headers-full exhaust valve springs, tune, highflow air filter you could get to 8k revs and around 220-45 hp. I’m not a fan of the e85 but that could push even farther. After that it comes down to major $$ to start changing major internals and going to a higher compression ratio. Or a full out custom job like Celek is doing but it has taken him year+ and he is still not done but when it is I can’t wait to see the results. The fa20 engine imho will exceed the s2k engine with more time and work done on it. We know it can hold the pressures of FI and the high hp. Now it just needs to be tuned for n/a. Sad thing is n/a is so much harder and $$ takes proper attention to all details. I would have love to see this engine with a mechanical throttle though true N/A should have one.
