4age 20V Silvertop MAP CONVERSION

I was surfing around found this information .. thought I'd share and see if anyone has similar experience or not.

it goes like this.
Silvertop MAP CONVERSION
I will explain how a good vacuum reading for a MAP sensor on a Silvertop 4AGE, but for the rest of the conversion you're on your own. Quad throttle bodies, if you withdraw from a vacuum throttle, the vacuum will soon pulse making it unusable for a MAP sensor and less than ideal for something else, that vacuum as a fuel pressure regulator. You must draw from all four throttles to get stable vacuum. The solution is much simpler than what I was lead to believe. The 4AGE 20V has a "vacuum" tracks, in fact, a room that already ticking off all four gas valves for you. It is at the top of the throttle between the fuel injectors and connected to the PCV, often a part of the engine wiring is housed in a plastic sleeve. It is used by the AC, power steering, and there is a small line drawing of it I'm not sure what. The problem with using this vacuum that is being used by the IAC. To do this you basically an air chamber that is larger than an inch internal diameter required. I'm not sure how long it should be, but I'm assuming it must also at least one inch. Get a carbuereted fuel filter. One of the obvious ones, without fittings approximately the same size as the vacuum cleaner AC line .. Well, that's where I hooked it anyway. If yours is not free, get a T-piece and read it there. Let the element in the filter, simply evil and an extra layer of protection to add to your MAP sensor. I have a T-system and a number of adapters, and plugged into my MAP sensor and fuel pressure regulator. Now the fuel pressure is a steady 37 psi at idle, and I am able to map out my fuel curve with the AEM EMS. I am willing to bet it will work fine with an asphalt ECU if that is your plan for the conversion.

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