That is an odd result. The dampener screw should move. Are you sure the line is pressurized (you can hear the fuel pump run?). For the EGR tests you are saying that you did test 6(b) and engine ran rough? Also, for EGR vac mod you plugged ports P and R and blew into Q with air passing to filter?

The seal size is 10X20X6mm DBL METRIC SEAL. You can order this at partsamerica.com (SKF 563709), but I got mine from Motion Industries for $2.10 ea. You can also use a 10X20X7mm DBL if you like (SKF 563509).

The union bolt torque is 36 ft-lb. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=LU&P=17

The holes would only need to be 71 deg apart for 3 deg adjustability.

That is correct. The fuel-pressure up VSV is only used for a few seconds during a hot start to raise fuel pressure and help prevent vaporization of the gas in the fuel rail from heat soak. It is not used at any other time.

I think the first thing to do is confirm that the high air temp readings are accurate. It could be that the hot AFM is making the sensor read hotter than the air temp actually is. I plan to measure the temp in the accordion tube with a thermocouple and see if it matches the AFM sensor.

Why not buy from Toyota? 90116-10025 $1.34 each at Camelback.

@Mentat-vvo. Looks good. Do you have a disassembler for the Fujitsu MCUs?

I wouldn't bother with the ducting. My tests on the stock air cleaner show that the incoming air is pretty near ambient, the stock system pulls air from in front of the radiator and it works well. The problem is that the AFM get really hot. Put your hand on it after running a while. the air...

Torque spec is 13 ft-lbs. it's in the back of the TSRM.

45 psi fuel pressure seems odd. Should be 36 psi with vac line disconnected. I guess we'll never know.

The rear one has a bolt to mount the stay for the hose coming from the heater union. I am amazed no one still has this part? Its 87263 in this diagram http://www.cygnusx1.net/Supra/Library/EPC/291420/catalog.aspx?F=8716&P=1

Check the EGR vac modulator is working properly. especially Step 5&6 http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=EC&P=13

Penz Plat and Ultra are available at Walmart in 5 qt jugs.

I notice even on new cars they often don't perfectly match the bumpers to the body paint. Still, it looks pretty close from the pictures.

Thanks. So you mean you used a 2-part urethane clear coat on the front but not the back? I would expect that to be a better finish too.

Looks good. Did you use a primer or adhesion promoter for your bumper repaint?

The pink is a OAT coolant (sebicate),and it is said that it does not have additives to protect against copper/brass components in the older cars. Use the red stuff instead and premix it before adding to the car with distilled water.
