It does look like a weak alternator. Could be worn out brushes which is a cheap fix. Where is your ground probe connected when you are making these measurements? You should measure the voltage drop across the major cables in the the charging system to rule out high resistance in any of the...

Drain and pressurize the cooling system, then scout around the engine with a stethoscope. Remove the plugs and drop the scope hose into each cylinder listening for escaping air. Obviously you need to find a quiet place to do this.

I've got a soft spot for 70's italian cars, so sexy but engineering definitely took second fiddle. I still have nightmares of snapping bolts and cracked castings from the last one I owned.

Fantastic. Did you keep the original wiring feeding the MKIV fuel pump? Is that an Espada you have as well (at first I thought it was a Pantera, but the details were a little off)?

Could you post up the lengths for the four lines as a reference for others. Thanks, and it looks awesome.

I'm no turbo expert, but it seems possible that it is clocked wrong and that is causing the ports to not be aligned right.

Plastigage your cam bearings too. You may be in a for a nasty shock.

Oil squirters are listed for all North American 7MGTE blocks starting 08/86 and ending 05/1993. They don't' seem to be listed for 08/86 to 08/87 7MGTE blocks outside of NA.

I sent my CSI to RC engineering for cleaning and flow test. It was cheap.

I am sold out of reader boards! I would never have believed the interest would have been this high when I started, but that is the current status! We will probably run more but not for while as a redesigned daughterboard would need to be completed first.

Please comment on the Diamond D6. I've been thinking about putting those in for a long time now. Did you keep the stock rear boxes?

The entire branch should be 4inch, but if space is an issue, smaller diameter will still work. I would think a T-junction would be best, to keep the main pipe air flow more uniform. A y-branch works too if you need it for fitment reasons. Ideally you want it in the middle of the resonant...

Wow! That's a complex assembly to reproduce. Hope you can provide more info on price.

You could get away with smaller diameter piping for the stub pipe. The diameter changes the characteristic impedance of the stub, which ideally you would want to be the same as the other pipe. The smaller stub will not cancel quite as well, but will still make a good improvement. For any...

I assume he is talking about a replacement "headlamp door". Maybe this point could be clarified. i.e. Parts 53131A/53132A here http://www.cygnusx1.net/Supra/Library/EPC/291420/catalog.aspx?F=5301&P=1

Mine occasionally does this, especially when the A/C is on. When it was under warranty a long long time ago I complained to Toyota. They said nothing wrong could be found. The next step was to push to replace the transmission, but I figured that would do more harm than good in the long run.

If you look at how the program is structured, it is basically geared to provide a subsidy towards the purchase of a new truck, especially large trucks from Ford/GM/Chrys that each have some models that just barely meet 17mpg. For large trucks you only need to show a 2mpg improvement (from a...

The Supra qualifies at 18mpg combined! :biglaugh: The new “cash for clunkers” program, which was signed into law on June 24 provides subsidies of up to $4,500 toward the purchase of a new car or truck if your trade-in is a clunker. The law defines a clunker as a vehicle that gets 18 miles...

The only way you get a coolant leak inside the turbo is if the housing cracks.... not very likely. Any gurgling noises on a cold start?
