TVIS?

[Apolan]

On the subject of 4ag vs honda. Before hachi i hade a 4th gen civic ('90) w/ a d16a9 (i think). This is also the 1600 ccm 16 dohc engine, w/ similar outpt 130 hp.. aso the car wighted around the same as the 86.

It can still be felt - the honda engine (which is similar to the ZC ivan mentioned) pulls harder and harder as the rpms increase. No vtec here. it has a redline at around 7500 rpm, but you feel alot of power above 7000. Im pretty confident it would make quite some powere over 7500 too. Though w the 4age there is more torque down low. And its not fun to push it over 7000 or 7300 perhaps.. The car is more jumpy at low rpms. Perhaps this is the combination of better response, tvis, rwd etc. But it definitely feels different than the honda unit, although the specs are similar.

I read on bill Sherwoods page that it would be sensible to keep the TVIS i f you have cams that are less then 260' duration:

Quote:Note that with cams larger than about the 260° mark you will actually benefit from removing the TVIS, if fitted. The TVIS, when used with cams smaller than about that duration, will give you more low end ( < 4,400rpm) power, but this effect disappears with the bigger cams.
