Real Fiero Tech

2000 Deville has a 150A alternator. It has a liquid cooled rectifier bridge.
Model number LR-630.


The water cooling circuit def. works cause I have never had one fail on me.

the amp internally regulates to pr0bably 12v. The higher voltage is going to just heat up the voltage regulator more. Thats how they work, they discharge the extra energy by heat. his lights however will still dim, they will just be brighter then dim to a normal level. I really have to suggest agai...

If you look at the internal regulator switch that feeds B+ to the field coil you will see the square wave AC voltage sense line that tells the regulator that the field coil needs to be turned on. The voltage regulator operates that switch at 400Hz and PWM controls field coil current to regulator vol...

Can you adjust the pickup tube depth?
If you can, put it as low as possible, put 1/4" of clay on the pickup screen install the oil pan and your depth is set, fix the pickup tube to where it came out.

Will, I will almost gaurentee that if you pull the heads, you pull at least one thread. From there on you should timesert all of the head bolt holes because you don't want to have to re tear it all down when another thread lets go during tightening. We never ever time sert just one hole when we pull...

I use red, just because I do not want them ever coming off unless I am taking them off.
A good 3/8 impact wrench will break them free, if not, a little heat and a nice smack in the middle with a punch will break the loctite bond.

Will is completely right. Unless you have a stupid orifice controlled PCV system which my Ecotec does, then leave it alone. Sometimes motors are known to pull lots of oil vapor through the PCV system at high rpms but putting an inline catch can to separate this oil vapor before it routes back to the...

Will, get a TIG. You don't regret it. It is slower but the control and versatility you have makes the speed seem like not an issue. If you can oxy actel weld, then TIG will take you a few weeks to really get good. Contrary to popular belief MIG is the hardest to master of hand held welding processes...

Being a GM tech....I have quite a few of the tools used in the disassembly....but in all reality they just help speed things up. I will get some pics up soon.

Pull the timing cover and do it right.

Or the Duramax has better rod bolts? Why assume that since its not the same design its weaker? It makes sense to off set the bolts like that so metal is taking the abuse not the bolts but I am not into diesels enough to say much. It is true that GM can't build a good diesel, but the new Duramax isn'...

This is def. a driveability/economy/emissions purpose for OEM engines. Low port velocities and cooler intake valve temps dont vaporize fuel well. So if you aim smaller jets of fuel directly at the valves and into the chambers, mixing will be better when at low engine speeds, reducing unburnt hydroca...

Use the right tool the first time....and go by a pry bar, that is why the sell them.

With a car that light the rears don't need anyting better in the rear that a solid rotor. Sure a vented disc is better but when it comes down to it, the solid rotor is quite adequate consider these aren't cars that are going fast like a Corvette would be. I think the GXP's have upgraded suspension a...

14.7v is what the alternator should be charging at. It will be kept around this by the voltage reg. and is just fine.

88 cradle?

Everyone I have know who have the non dustboot willwoods, which includes 6 piston vette brakes and 4 piston wrx brakes, say that the lack of dust boots isn't a big deal, they havent had a problem in the 2 and 3 years they have had them.
But thats just what I have heard

Those are way too small to be vents. Solstice fender holes?

Increasing compression will net more torque across the power band and therefore more torque. Not much of a way to guess how much power you will make per .5 of CR increase. Depends on a lot of things. You could make a balls to the wall 11:1 NA motor. You could probably even make it run well on pump g...

Cool that he can do illusions and shit but still doesn't impress me as much as jesus did when he walked on water, that shit was for real holmes
