Good day guys

Can someone please post images of both the 2 liter head and of the later 2.5 liter head.

The say the 2.5 head has much much smaller valves and hence the engine cannot breathe well. I's like to compare myself.

Thanks a lot!

 

There are more differnces to consider, the valves are the same size, but the I.D of the combustion chamber is larger than a 2.0 and the position of the position sensor is differnt as well as a differnt type of sensor. i.e. don't try and fit 2.5 on 2.0 and don't try and fit 2.0 pre hawk to a hawk. 2.0 JDM hawk heads will fit though.

 

what is the 'I.D' of the combustion chamber?

thanks for the answer

 

Internal Diameter

 

thanks Scotty.
