I can't decide if i want to buy 3:42 with a 2000 stall or 3:73 with 2600 stall. The 3:42 and 2000 will be a lot cheaper in parts but someone said i will take off like a Rocket is I do the 3:73. i dont know what i want to do.
I have a 96 z28 a4, best time 14.0@ 98 mph. Also with the 2600 stall and the 3:73 How high are my chances of break my axel or ring and pinon

 

Theres no reason to install a 2000 stall. You wont notice a damn thing. If ANYTHING, get the 2600. You'll be happy with either the 3.42 or the 3.73's. Again, make sure to get the 2600 stall

 

If you really want to get the full potential out of it get a 3800 stall with a set of 3:73's. That will realy wake up the car and you will feel how much torque you gained with it. The bad thing is that you will need a set of ET Street Slicks to go with it bc i used that set up with some street tires and almost hit the wall. But with the tires it is well worth it. Dont get the 2000 waste of money.

 

The 3.42 with a 2800-3200 stall is ideal. The 3.42 has more meat to it than a 3.73 and looks much stronger. I am pretty sure you would not be able to feel the difference between the two gear setups. I went from a 2.73 to a 3.73 and could barely tell. The stall speed is more of a personal choice. With only a 2600 stall I always waited for the car in front of me to get about fifteen to twenty feet ahead before touching my gas from a stoplight. I don't think 3800 is really a good choice unless you drag race a lot and you only drive the car on weekends.

 

I have an LT1 Caprice, obviously heavier, but I have an Edge 2800 stall and it totally rocks! The 2000/2600 are most likely a 12" converter as going to a 9.5" pretty much relegates you to a minimum of 2800 as a stall. Going with the smaller converter gives you much less rotating mass (read: more horsepower) and modern h/s converters have tamed just about all of the bad manners of the ones from even 10 years ago.

If I had it to do over again, I would pop for a 3000, it takes about a day to get used to it and it may be the best mod you will ever do.

As I said, I love the Edge product, especially for the price, but you can go with another brand if you like. Just don't go with a cheapie brand that just bends the fins on stock parts. Spend the $500 to $800 it takes to get a quality part.

Not sure on the rules about posting links, so if you google "edgeracingconverters" you will get their page. If you decide to go with them, call and ask for Andre, he is very knowledgable and patient, he will treat you right.

Oh yeah, you will be buying a new rear-end with a higher stall. I had no trouble as I get the 8.5" unit behind my driveshaft from the factory.

 

thats funny, when i went to 3.73s from 2.73s i noticed a HUGE just going down the road the first time, and was barely driving the car at the time (this was during a huge tranny rebuild issue so i only got to drive her on weekends.. the trans was tore apart all week every week =/, but as far as which gear, if you do a lot of interstate (70+mph) driving then go for the 3.42s.. the 3.73s will rape you on gas at 70-80mph for long trips.. (last trip i made was 20mpg with the 3.73 interstate the whole way)

 

I'd recomend the 3.73's with at least a 2800 stall converter. There isn't much difference between the 3.42's and 3.73's, I went with 3.73's just because the bigger number is better :P

What he said ^^ I also recomend the Edge converters. You can pick your stall speed and your stall torque ratio for a few hundred bucks less than the precision industries converters. My edge 3000 stall has got me a best 60' of 1.687 with drag radials, nearly a .3 increase in the 60' over the stock converter

Automatics ain't nearly as hard on the rears as the 6 speeds are, I wouldn't worry too much about your rear if these are the only mods your doing.

 

I agree with the 2800-3200 stall. If you can get your hands on a Precision Industries Vigilante, do it. They are pricey, but they are hands down the best converters. Got mine used from a guy i knew in florida who only put 500 miles on it. Best mod i ever bought.

Im gonna do 3.42's myself just because i like the beefier gear thickness that comes with the 3.42's and i also only go to the track just about 2 times a summer. So 3.73s are not really worth it. Id rather have the reliability of the 3.42s since i drive it daily all spring/summer.
