4.10 gears....

[FunkZ]

I don't know how similar the two harnesses are. Best bet would probably get ahold of wiring diagrams for both years and compare.

thanks funk....I'll go grab the holy book of haynes....

[tdz16]

Well, actually, I was just rereading what you wrote and you said the "harness and pcm". I plan on getting the engine harness and computer because It would obviously make things a lot easier. But is the obdII connector on the engine harness and just run into the car? Or is that part of the dash wiring harness?

[FunkZ]

I'm not sure. I thought the wiring harness extended not only to the engine but also inside the car. But you're saying the wiring that goes inside the car is a different harness? I'd think you'll want at least the ODB-II connector so you can hook up a scan tool or reprogram the PCM in the car.

Well funk, i get my car tonight(the 94) and tomorrow i'm off to pull the engine and whatnot from the 97. Its gonna be a long night/day/night...haha. I'm gonna just pull everything I can.....

[FunkZ]

Good luck, let us know how it goes.

why are you getting 4.10 gears? there is really no reason, they will hurt your 1/4mi when compared to 3.42's and 3.73. so far 3.42's have the best times. this is really a waste of your time and money, just get the 3.42's.

[tdz16]

Well, i bought it from a kid for 400 bucks. It's girdled, new gears, new carrier, new clutches, new everything....like, well worth the money so i just jumped on it. But with a larger powerband like i'm hoping for with a custom supercharger setup, it should work better. People with V8's live for 4.10's so i'm sure they'll be fine with a powerful v6.....just my opinion....

[T-Punk]

i dont think shirl even runs 4.10's and she has run in the 11's with her nitrous SC setup. You will not be happy with those gears until you get a power adder. also the V8 guys who live for 4.10 gears are usually well over 400rwhp which is really quite a feet for the V6. good luck but i think you really might be happier with a lower ratio gear set.

4.10's will haul ***. For some reason everyone says they wont run good in the v6 because "hardly anyone has done it." Our car is just like anyones, the more gear you run, the quicker it will run until u put too much and have to shift into OD (5th M-5 or 4th-A4). It doesnt matter how much HP you have as to what gear you can run. And really, the less HP you have, the more gear you need. I can garuntee if i didnt have to drive so far to school i'd have atleast 4.10's in mine, maybe some 4.56's. Put it in and get after it, you will be happy!

hey t-punk, thanks for the advice, I do really appreciate it. First I have to finish my first project of swapping in the 3.8 m5 into my 3.4 a4. Then I will see about the putting the rear in. I may wait for a power adder to put it in, or if i'm feeling energetic put it in for a few weeks after I get the new motor/tranny setup glitch free just for kicks. i guess its all up to experimentation. Wicked, thanks for the backup btw, but you have to consider power curves like t-punk is saying. Its all numbers and graphs that you have to take into account also.

[T-Punk]

wicked, you really need to think of why certain gears are optimal for certain projects as opposed to others. Yes the 4.10's will get you out of the gates faster than hell but you will hit your top speed just as fast unless you have enough power to keep going. 4.10's are optimal for the 400+ range imho but if you just want quick acceleration they are great. Your quater will be hurt with them if you dont have the extra power you will need to reach high speeds. tdz16 good luck with the swap, i doubt you will be dissapointed. the 3800 has a lot more performance options than the 60 degree v6's.

thats completely wrong dude. How much power you have has nothing to do with what gear you can run. And like I said, the less power you have, the more gear you will need to run fast. I garuntee him running 4.10's will outrun anything higher (numerically lower) that he runs. He just needs to turn the speed limiter off so he doesnt hit it. You can use Shirl as an example but she has tons more power than most here which means she can pull a higher (numerically lower) gear a lot better than a NA car with much less power. The more gear you have, the more of your power you will put to the ground. And with the little amount we have, we need to put as much as possible down to run quick.

[T-Punk]

so what you are trying to say is that a 4.10 gear will not only make you accelerat quicker but also make you faster? that makes 0 sense, do more research on gears. if this was true everyone would have the highest # gear they could find, and i wasnt talking about hitting the speed limiter i was talking about purely running out of power because you would hit you highest gear and be at your RPM limit (unless you upgrade internals to take more than 5700-6000rpm) where as the 3.42's and 3.73's still have room to accelerate to a higher speed. im not even going to go into why you dont need to let your car rev past 6000rpm due to where you make peak power with the 3800.

Go for the 4.10's - you'll never regret it with the T-5. Little G's best times with his 3.23 posi was about 14.6, now with a 4.10 posi he's runnin 14.23x coming through the traps in 4th gear at about 4500ish rpm (with only a few other mods).

The numerically high gears (such as 4.10s) increase your torque multiplication, and thus greatly improve your 1/4 mile performance. Going from a 3.42 to a 4.10 gear will only hurt you if you plan on doing land speed type racing over long distances. The theoretical top speed of a 3.8 with a T-5 and 4.10s is still 151 mph, and no one here is going nearly that fast in the 1/4 mile.
