Re: backside of waterpump tube
You need the tube to circulate the coolant before the thermostat fully opens. There should be an O-ring on both ends of the tube. Replace the O-rings and then coat both ends with RTV just before installing the head. Dave W

If you do not have an inspection requirement then the engine will run OK without the EGR and most of the other emission controls. Your will need the O2 sensor, it's missing on the exhaust manifold. You will need a replacement or a resistor in the circuit to send the correct voltage to the ECU. You a...

Re: How did you improve your fuel economy on a 4ac?
About the only easy change is the exhaust system. Look at headers and low restriction pipes and muffler. A better exhaust will reduce pumping losts. If the exhaust is custom, get anti-revrsion in the primary header tubes. You will probably have to adjust timing because of the improved scavenging. Da...

Union bolt? Is that the bolt in the center of the plate that attaches it to the block, or the bango bolt that you need?

Re: 4age head bold. HELP
I assume you mean studs holding the head on the engine block. Typically you just put two nuts on the stud threads and tighten them together. Then you can back them out just like a bolt. If that does not work you can get a stud removal tool. It's a cam design that tightens against the shank of the st...

Re: 4AG Won't Run/Dies Immediately
If it runs for a second then the fuel and igintion systems are probably good. If your ECU does not see any signal from the AFM at start up it will shut down the engine. Check the AFM connection and wires. Manually move the flap and verify a resistance change. Davew7

Re: T50 good for autocross??
Auto-xing using a bone stock t50, should not be a problem, if the engine is making less the 180 HP. The stock trans will easily handle that type of abuse. I typically only make one shift off the start line and then run the rest of the autocross in 2nd gear. Dave W

A 2nd in-line pump would not help. The problem is fuel pick up. You need baffles around the fuel pump pick-up. The GTS has a baffled tank to prevent this problem. An option is to put a lowered sump in the bottom of the current tank and extend the pump mounting bracket to pick up the fuel in the sump...

The reason for the 7* is because you will start sideloading the piston and seals in the master cylinder at greater angles.
