Pictures of my reworked 1st Generation Head |
|
|
This is a picture of one the intake ports. You can see how the valve bowl
have been opened up. Some of the casting material has been removed from the sides. The bottom and
top were untouched. They are left rough to help the atomization of the gas, when it is injected in.
This is another picture of an intake port. You can see the swirl polish in the
stainless steel valves.
This is a picture of the 1st generation intake manifold. I had it polished smooth and
JetHot Ceramic coated.
This is another picture of the intake manifold. In this picture you can see that I had
them spray the ceramic coating on the inside of the manifold also. I had this done because the
ceramic coating is a slick surface and this should help increase the flow. I am hoping that
it will be similar to extrude honing.
This picture shows the bottom of the head. The intake valves are on the top and the exhaust valves are on the bottom.
This is a close up of the bottom. You can see the size difference between the intake (top) and
exhaust (bottom). The exhaust valves are 1mm oversized. Stock, the intake valves are standard steel. I have
replaced mine with stainless steel.
In this picture you can see the exhaust manifold, head and intake manifold.
You can also see the AEM cam gears. I bought two, but I have been told that I really only
need the exhaust cam gear. My intake cam is monitored by the ECU with the cam angle sensor.
This is a close up of the insides of the head. It is difficult to see, but I have replaced the
hydrolic lifters with the latest Mits replacements. They have a larger diameter hole on the top, and are
not supposed to tick. You can also see the new valve springs. These are slightly stiffer then stock. I am
not going to rev the car over 7500 RPM, so I did not need very stiff springs. I have also replaced the retainers
with Crower Titanium retainers (on top of the valve springs). I have been told that I will notice a big difference
with these, because they are so much lighter than stock.
Picture of the head and exhaust manifold. You can see some of the porting done to the exhaust port.
This is a picture down the #4 exhaust port. You can see the work that was done to smooth it out.
This is a picture of the #3 exhaust port. Again you can see the port work that was done. You can also
see the work that was done to the valve bowls.
