Springer's LT4

Thats really hard to guess Mike... depends mostly on the driver, track conditions and weather.... best way to find out is just go to the track and find out.

TIMSPEED

Personally, I would have went with a set of 3.75 gears, you'd be much happier with those in the LT1 motor.
Just my $0.02

CORVETTE MIKE

Ya but i dont want to loose to much of my top end,so i went with 3.54

vader86

i'll guess somewhere in the mid 13's, on the high side maybe

I'm going to guess 13.2 to 13.4.

I believe that nickd posted a 1/2 second increase on his. I never ran mine with the 2.59 in it before going to the track. I have a friend that has a 94 A4 with 3.07 gears and he was running 13.80s. My best is 13.49 and consistantly 13.50s. Also keep in mind mine is a vert. We both are running street tires, were running at the same tracks on the same days, and have little track experience. I dont want to start any flames here but I wonder how many of these people who tell you to go 3.73 instead of 3.54 have ever had both gears with a A4. I can tell you that I went with the 3.54 because the price of a rebuilt unit was much cheaper then I could find a 3.73. I paid $759.00 exchange at Zip on a group purchase, and because I live about 90 miles away I was able to drive there and save the shipping. When I purchased mine I ask Justin why zip only is doing the 3.54 and not the 3.73 and he explained it to me as being the 3.54 will hold up better. Im not going to try and explain this, if you have questions about it call him. Justin is a very good at differentials and he would be glad to explain the differences. I origionally wanted the 3.73 but I was looking at about $500.00 more for the rebuilt diff. For a 5% gear change I couldnt justify that much money. One other point I would like to make is if you read any of the testing that TPIS did with the 92 LT1 vette that they used as a test car, they installed 3.54 gears in it as well. Sorry about ranting on about this but if you do change gears Ill bet it will be the best seat of the pants improvement you will ever do for the money. Good luck!!

I went from 2.59's to 3.54's in my 94 convertible. My best with the 2.59 was a 13.82@101mph,
since the gear went in I have run consistent 13.30's@104.5-105.5mph.
I have run new bests of 13.25 @ 105.9mph and 13.23@105.5mph.

Did the rearend you purchased from Zip come with the side yolks? Did you also purchase the heavy duty rearend cover for $325.00?

Newbie question... What's the stock rearend on a '93 6spd???

Is it a 2.59??? :U

vader86

Should be something like 3.45. Check the RPO codes. It wouldnt have anything less than a 3.07.

rideklein

RPO G92 (3.07, I think) was the "performance" rearend for auto's only in '93.

This isn't looking good.

:U :U :U :U :U

vader86

if you have RPO G92, what is your other Gxx code. I'll bet that G92 for a M6 is 3.45

93 ragtop

No side yokes on mine. I had to transfer them over. The cover was not out yet at that time when I purchased mine. I to, would like to know more about the hd cover.

mfranco

About when did you purchase your rearend? The reason I ask is because when I spoke with Justin yesterday he told me that they come with the side yolks but I thought the price was awfully cheap to include the side yolks.

Hi Mike,

Here are numbers you requested:


0-60mph 60-100mph 0-100mph
Stock 94 6 speed 5.3 sec 6.7 sec 11.8 sec (24 cars tested)
" " Auto 5.6 sec 6.9 sec 12.4 sec (16 cars tested)
Similar 94 Auto* 5.0-5.3 sec 6.5-6.7 sec 11.3-11.7 sec ( 2 cars )

* With only two cars tested that were setup like your is now, your time to speed should range in the group listed here. We believe that more cars need to be tested to get a really fair estimates. Sorry, we do not do quarter mile testing.

Hope this will be of help.

Stan :chevy

I'm throwing in 3.54s and a 2800 stall Vig next month and I'm hoping for low 13's... Dare I say high 12's??? :D

cprgmr

I just purchased the 3.54 diff a couple of weeks ago and I had to spring for new yokes (felt better installing brand new ones), snap ring kit, and a MatCo snap ring pliers. Last time I talked to Justin, he said they were seriously considering installing the yokes at Zip on new diffs. Sounds like they went that way. :)

jay17

I say you'll get 12's with sticky tires.

jay17

All 6spd have 3.45s.
