2 liter civic vtec engagement

Bruce71138 · Jan 21, 2017

After reading some specs on the K20C2 engine I noticed that the vtec engages at 6100rpm with a 6700rpm redline, i had my LX coupe in 3rd gear the other day and could definitely feel the vtec engage at 6100 rpm. i was just wondering why Honda would have vtec engaging at a relatively high rpm basically only giving you 600 rpm when vtec engages until you have to shift, Im sure there is a good reason for this was just wondering what the reason is.....thanks

This is the Si sub forum. i think you will get a better response from the correct forum. The SI will have a 1.5 turbo.

Helps with fuel economy.

This is done so that there is a gap between the 1.5 t (non si). If they had the vtec engage at let say 5500 I don't think the 0-60 would be any different then the 1.5t in manual. Fuel economy is another aspect. The engine would have similar driver dynamic to the k20 in the 8th gen si.
