93 a4 vs 93 m6
93 a4 vs 93 m6 just wondering... i raced a buddy of mine (93 z a4, high flow cat, no stat, moroso cai, 3 inch cut out, kuhmos...dont know if i spelled right) he said he made 13.8 et...i have 93 z m6, 160 stat, fan mod, tb pass, cai, 2 1/2 exhaust flowmasters stock headers, kuhmos on 9 1/2 ss rims...i raced him from a dig...we both spon bad i got half a car in front of him by 2 gear...scratch 3 
...I lost by two car lengths on a lil more than 1/8 mile street strip... 
...i believe i can beat him if i race again...prob is...he now has tb pass, and 1 1/3 shorties/y pip....how much will that give him and will he kill me or just beat me by a car or so.

a lot of the mods your talking about don't make any noticible difference for your car.. for example, kumhos are street tires, they'll make no difference whatsoever in your cars performance. thermostat doesn't do much either, TB bypass and high flow cat won't do ****... so basically you're talking about a 93 Z28 A4 with a moroso CAI and a cutout vs a 93 Z28 M6 with a CAI and a flowmaster catback... shorties and y-pipe won't make much of a difference, but it'll be noticible. he'll take you by a couple of cars.
The gearing of your car is lower than his car though. The 93 M6's came with a more aggresive 1st gear making it as if the car has more of a 3.42 gear rather than the 3.23's in both cars(Im pretty sure they both cam with 3.23's. Please correct me if Im wrong.). I know its not much different but every little bit counts. Practice launching your car and get ahead of him from the start and if you hit your shifts, you should be able to hold him off. Go to the track and run him multiple times. He'll win sometimes and you'll win sometimes. Its more fun that way.
yeah i know the mods are more like tunes....but ever little counts...really i only posted so ya can picture the car better...i cant race him yet there is certain...tick tick....sound on my car and sounds a lil rough...once fixed then of course well go back to bay town.
i thought it was a bad rocker arm...so a friend(mechanic) checked it out and adjusted them...said the only prob he found was a bad oil pressure...so im going to change the oil pump...if that doesnt fix it i might have to look at those lifters...question is does a lt1 supposed to have some sort of ticking sound or should there not be any ticking sound at all.
The stock injectors on the LT1 tick very loud. The lifters also make some noise. Neither are bad noises, just kinda annoying.

If the ticking isn't very violent, then there's most likely nothing wrong. (key word- most likely) Older motors start to get noisy.
brandbo, the 4L60/4L60E had 2.73 gears with 3.23s as an option. All T-56es have 3.42s.

Verdad Gallardo well I mean the motor picks up great...so what im trying to do now is get better oil pressure...by the way how is your(anyone) oil pressure...how much does it go up and how low will it get...this way i can compare.
How many miles are on your car? When I hit 120k, I noticed that my oil pressure started to decrease just a little, not enough to hurt anything but I get dont like to take chances with stuff like that so I switched oil from 5W-30 to 10W-40. Over time, our motors, just like any motor, get older and the internals get "sloppy" and the rings dont hold pressure like they did when new so you have to use a thicker oil to compensate for this. A thicker oil might be hat you need.

In 93, the there were 2 different versions of the M6, the M28 and M29. The M28 gearbox came with 2.73 gears and and the M29 gearbox came with 3.23's. There was no 3.42 option.The gear ratios or the gearboxes are as follows...
M28 M29
3.36 2.97 --1st gear
2.07 2.07 --2nd gear
1.35 1.43 --3rd gear
1.00 1.00 --4th gear
0.80 0.80 --5th gear
0.62 0.62 --6th gear
Im still researching the A4 options but Im pretty sure its the GU2/GU5 story, just like the other years. Ill let ya know. Good stuff man

The M28 (F-Body spec wide ratio) T-56 got 2.73's.
The M29 (Close ratio Viper tranny) T-56 got 3.23's. This is the preferred tranny.
Noteworthy: The M29/3.23 combo is actually a steeper overall gearing than the 94+/3.42 combo.

Yeah, my buddy has a 94 M6, and we put some 3.73s in it, from his 3.42's and he can keep up with my 93 Z28 383 Stroker till end of 2nd. Sound weird? well it did to me too, ya see my camaro had the M28 in it, 360lbs/tq rating, and it busted so I put the M29 in it, not realizing the gear change...After reading up a couple of paragraphs, now I know why it takes my *** forever to get going...I have 2.73, with a 1st gear ratio of 2.97!!, to his 3.73 and 3.xx somethin. Makes me feel better though, knowin how much i'll be able to gain. Do you guys think 4.10's or 3.73's would be a better choice w/ the M29 tranny?
