Do you notice something on this?

[cybtech]

die lo... all this while i'm using E1 and pressing the oil hard....
any after effects (other than the taxi sound)?

 

[TRD.AE92]

Wahahaha... I already know many people will not aware of it... Lolzzz

 

[cybtech]

now who got sell C6/E2 sure got business here....

20V Sensor Locations Vacuum Hose Id 1, Vacuum Hose Id 2 Engine Manual Club 4AG
Each of the two brake booster vacuum lines needs it's own check valve before the T fitting.

SILVERTOP MAP CONVERSION
I will explain how I got a good vacuum reading for a MAP sensor on a silvertop 4AGE, but for the rest of the conversion you're on your own. With quad throttle bodies, if you draw vacuum from a single throttle, the vacuum will pulse rapidly making it unusable for a MAP sensor and less than ideal for anything else that uses vacuum like a fuel pressure regulator. You have to draw from all four throttles to get stable vacuum. The solution is a lot simpler than what I was lead to believe. The 20V 4AGE has a "vacuum rail", basically a chamber that is already tapping off of all four throttles for you. It is on top of the throttles between the fuel injectors and connected to the PCV, often beneath part of the engine wiring housed in a plastic cover. It is being used by the AC, power steering, and there is another small line drawing from it I'm not sure for what. The problem with using this vacuum source is that it is being used by the IAC. To overcome this you basically need an air chamber that is larger than one inch inside diameter. I'm not sure how long it needs to be, but I'm assuming it should be at least one inch also. Get a carbuereted fuel filter. One of the clear ones, with fittings about the same size as the AC vacuum line,.. well, that's where I hooked it up anyway. If yours isn't free, get a t-fitting and splice it in there. Leave the element in the filter, it wont hurt anything and it will add an extra layer of protection to your MAP sensor. I got a T fitting and some reducers and connected it to my MAP sensor and fuel pressure regulator. Now the fuel pressure is a stable 37 psi at idle, and I am able to map out my fuel curve with the AEM EMS. I'm willing to bet it will work just fine with a blacktop ECU if that is your plan for the conversion.

COMPRESSION CHECK
When shopping for a 20V 4AGE, check the dry compression. There should be less than 14psi difference between each cylinder, 156 psi minimum pressure, ideally 193 or more.

IMPORTANT NOTE: I did not come up with this page, or the part numbers. I only copied this from shaundrake's (guy who used to be on club4ag.com) site. So I really can't vouch for the accuracy of the part numbers.

guys, seriously need advise on 4AGE 16V pistons in 4AFE 16V block. my car is in the workshop getting an overhaul now. handed them the pistons for the swap...some mechanics say can but some others are skeptical! Made me feel kinda scared and indecisive now. Any advise is much appreciated. thank you

This is correct oil filter for 20V:
90915-YZZC6
90915-YZZE2
C6 is using sponge like filter element while E2 is using paper. Could be due to different filter element, E2 is slight taller than C6.
If using a wrong oil filter, perhaps the VVT pulley will die earlier (produce "clack clack" diesel sound)??

Yup...

Here's the C6 filtering element...

And here's the E3 filtering element...
somehow, E2 got a "bypass valve" .

Source : 4AGE 20V Blogsome



Here's the bypass explanation...

If you wait too long to change the oil and oil filter, there is a danger that the oil filter might become plugged. To prevent a plugged oil filter from starving the engine for lubrication, oil filters have a built-in safety device called a “bypass valve.” When the differential pressure across the oil filter element exceeds a predetermined value (which varies depending on the engine application), the bypass valve opens so oil can continue to flow to the engine. But when the bypass valve is open, no filtration occurs. Any contaminants that find their way into the crankcase circulate throughout the engine and act like an abrasive producing accelerated engine wear.

somehow...
1) When using E2 ...some say the response, the "kick" not as good as C6 ...I can't say much, cuz I never used one...

2) C6 it's hard to get, as "they" said, C6 not longer imported or discontinued from Japan... :( :(

But then...E2 still ok to use rather then E1...which clearly too small for 4AG engines...

You might need to read Sifoo Acoustic page : my-acoustic.com

Note : C5 swap with E1 and C6 swap with E2

c6 filtering element looks like zxr250 oil filter..maybe can use that one..high rev engine summore..16.5K rpm..
after reading this topic only i know the oil filter got different type and not suitable for various engine..
now, i change to the correct spec of the filter..

 

[netmatrix]

C6 looks less restrictive than E3. Explains lower oil pressure.

 

[ryuichi]

hmmm.....that's also what i heard from the spare parts shops that i frequent...said C5 n C6 no longer available...most now is coming in from Thailand....
even B6 filter that I use for my Svt now change to D2 which is made from Thai as well....
