"Congrats, mr ford, you've been served by a motor with less fluid capacity than the soda your gf is holding."

 

another cool this was what Toyota came up with on the 4age engines. It was kinda the same thing as the RX-7's it had a vacumm actuator that at a certain RPM would open a second set of intake runners. Not really Vtec but it worked well. I had an '85 MR2 that could scoot for being a POS. I think they called it TVIS- Toyota Variable Intake System.

 

i never heard of the yota one, interesting.

 

Ok ok cool im glad someone brought this up or I would have never remebered. Ok so hondas are like hemis, plz explain how I thought it was because they had hemispherical pistons or some **** plz help me on this I have like a 20 dollar bet that hemis are like hondas but didnt know how to explain it.

 

In a HEMI engine, the top of the combustion chamber is hemispherical, as seen in the image below. The combustion area in the head is shaped like half of a sphere. An engine like this is said to have "hemispherical heads." In a HEMI head, the spark plug is normally located at the top of the combustion chamber, and the valves open on opposite sides of the combustion chamber.



Another factor with a HEMI head is the size of the valves. Since the valves are on opposite sides of the head, there is more room for valves. The engine design that preceded the HEMI was a wedge-shaped combustion chamber with the valves in line with each other. The inline arrangement limited valve size. In a HEMI engine, valves can be large so the airflow through the engine is improved.

Then there's Mazda's 4 rotor job, the 787 or whatever designation they were giving it. It has variable length runners from hell, plus a variable exahust system.

 

so mazda had the 6 port vtech in 82-83 and honda waited until 91.....
