Re: Overheat problem on small port 4AGE

I can see coolant spill out when rev engine to 2-3k rpm, is that normal? If the engine is warmed up (thermostat open) with the radiator near full, you will see the coolant circulating in the top tank when you have the engine idling. This is normal. Rev the engine and the coolant level will "su...

Re: Carbed 4AGE dizzy issues

And if you can't find the Bosch igniter and coil at your local junkyard, there is another possibility... the venerable 4-pin HEI igniter that was widely used on a range of older carbed US cars, and some early EFI models. These are said to be a dime a dozen in the junkyard, and it should be easy to p...

Re: Extrude hone small port mani

I don't have any data but if I was using the adapter plate I would not be too concerned about any loss of flow due to the taper on one side of the port. If anything it may be helpful in promoting swirl in the combustion chamber and that is something that is said to give a better burn for improved ef...

Re: Silvertop loosing power while driving..

Those pressures are indicate a normal healthy fuel pressure. The rail pressure increases as you blip the throttle which is how it should be, and the return pressure goes down because more fuel is going into the engine and less back to the tank. Go ahead and replace the fuel pump and filter. I'd be s...

Re: Silvertop loosing power while driving..

Sounds to me like it running extremely lean... barely enough fuel to support combustion. You definitely want to try the fuel into a bottle test while it is in that condition. An engine needs very little fuel to idle, but once you open the throttle and put a bit of load on the engine the required fue...

Re: Silvertop loosing power while driving..

It certainly sounds like you have a fuel supply problem. So to clarify... 1. Before the problem the engine ran fine... normal power, no hesitation ? 2. Was there a gradual loss of power or did it just lose power completely ? 3. When it started again and you were driving, did the engine run normally ...

Basically, as I see it, if you want to run a simple MSD ignition only setup without any form of ECU, there are two separate matters to be resolved.

It seems to be very difficult to get accurate information as to how you make an MSD box work with a Toyota distributor. The 4AGE distributor has VR (reluctor) pickups inside and MSD instructions only talk about "magnetic" sensors. VR amd magnetic are not the same. VR outputs a weak variabl...
