All 93 z28's had black tops. I dont think you could get keyless on a 93, at least it wasnt standard.

It wasn't an option, at least not when mine was made. My car was fully loaded, minus T's. I had to add an aftermarket keyless/alarm system, but that is good... It is a lot better than the factory system would've been.

I love my 93Z too
I only have 34K mi on it
no t-tops (Would like a targa top, but I heard they might be a bad decision)

I swapped the speedo display with a 94-96 one. JUST the display though. If you swapped the whole cluster RPMS won't work correctly.

While I'm here... anyone looking for 93-96 Z28 Wheels with new 245/50/16 Tires???

I need 18+ wheels! I have a brand new set of 2002 Chrome 17" SS 10 spoke wheels. With new 275/40/ZR17 Tires.

I believe the 93's had the 1.46 inch springs and the later years had 1.25 inch springs. Not positive but prety sure. Don't forget the 93's are faster. </font>
The springs were 1.250, the same as all other LT1's! Also the heads are all the same from 92 thrugh 97.

<font face="Verdana, Arial" size="2">For gear change - You should be just fine with the speedo gear for automatic. The speedometers on the '93 A4's were not electronic like in later years. </font>
Maybe someone can confirm, but I'm pretty sure the 93 A4s had electronic speedos. Meaning they were not cable driven. I would go crawl under mine and check, but it's been raining here all day; Still is actually.

I am almost positive that the last time I was under my car, there wasn't a cable coming from the tailshaft, just a wire..

<font face="Verdana, Arial" size="2">Oil pressure sender is directly above the oil filter instead of on the back of the intake manifold (unconfirmed)
</font>
That is the location of the oil pressure sending unit. Maybe this will help confirm it..
"The oil pressure gage sending unit is a variable resistor mounted to the engine block so it will sense the oil pressure in a main oil passage just downstream from the engine oil pump."

Ok, I'm looking at a factory service manual for a 93 Pontiac Firebird:

The transmission does have a speedometer gear (appropriately called the Speedometer Driven Gear)that the VSS (Vehicle Speed Sensor) attaches to. An electrical connector then plugs into the VSS.

So, everyone is correct here. The 93s do have an electronic speedometer, and the speedometer can be corrected for gear changes by swapping out the Speedometer Driven Gear. I can take a digital picture of the page I'm looking at if anyone would like to see the diagram.

93’s have a non-electronically controlled 4L60 automatic transmission (internals are swappable with 700R4’s). True but 93's also came stock with 4L60E's. Mine did.....

Gahlee.. some people.

NO THEY DIDN'T

You think the GM engineers just put whatever tranny they had lying around into the cars?

ALL automatic 93's are 4L60's, and practically identical to 700R4's, except better in some manners.

Gonna have to agree with the Gabemiester.
All 1993 A4 F-Bodies have non-electronic trannies.

GRRRR.....
I just took my 93 to the local trans pro due to a shattered 2-4 band. And yes mine is the 4L60E trans. Has electronic shift instead of a TV cable. It was the first thing they looked for to do an estimate.......
