wikipedia extract

Wikipedia is not a valid source man.

However, I believe that the CRX Video Catalogue released specifically by Honda which I have on DVD is valid. And that states that the first generation B16A found in the JDM EF8 CRX SiR produces 158HP and redlines at 8200RPM.

Though I think you're right, the B16A2 makes 160 HP and I was confused with the B16A II lol

But the alleged figures from the information you provided don't even give accurate power conversions from HP to KW. 1 HP = 0.7457 KW.

Therefore:
158 HP = 117.8206 KW
160 HP = 119.3120 KW
170 HP = 126.7690 KW

The figure from your quote that I have put in bold has also been edited (by you?) from the original text on Wikipedia - this is because Wikipedia states the following:

"Power: MT: 170ps (118.kW) @ 7,800rpm & 16.0kgm (156.91 Nm) @ 7,300rpm (AT: 160ps (114.0 kW) @ 7,300rpm & 15.6kgm (152.98 Nm) @ 6,500rpm)"

So, according to Wikipedia, the 'B16A second generation' makes 170PS/118KW? The figures don't even match up on that BS site.

Honestly I think there are also several more variants of the 'B16A' according to different sources that make either 158HP, 160HP, 168HP or 170HP. We need to find a more reliable source...
