Also, it misses the torque a B18 has.
A B16a SiR-II also has a 170hp, like the B18c4, but also misses out on torque.
And, the only difference with the B16a2 is a knock sensor and a few minor things.
When driving around in this part of the world, there is another type of weather (airpressure and so on), and a lesser fuel (lower octane), wich decreases the power of the stronger JDM engine right back to 160 or something like that.
If you want to get almost 200hp out of a B16a2 btw, read my post in the n/a section about different n/a set-ups.
