Mr Phil

A guy wants to trade me his 3.42 rear end for my 2.72. I don't remember if his rear is tcs or not. But with me not having traction control and him maybe having traction control will I have any issues with the install? I know they're is a different 3 channel or 4 channel connection. What will happen if I install a tcs rear on my non tcs car? Do I just have an extra connection that goes nowhere or is it more serious than that?

actually it would work as long as you don't care for tcs. BUT, you really need to think of why would you bother? either way you are probably getting 3.73's or 4.10's so my opinion is no don't do it.

Mr Phil

What do u mean either way I'm getting 3.73 or 4.10?

Sounds fishy to me.. Easier to swap gears out then drop two rear ends and re-install.. Don't do it.

342 vs 373 wont ever be noticed performance wise. Way more pros for 342s than cons and less cons than the 373s.

Changing a rear is pretty simple.

Mr Phil

well tim i dont have the mechanical expertise to worry about shims and backlash and all that **** if i were to just order a new gear set from summit or something lol

Think about it... Why would he want to trade rears just for gears? There could be issues with his rear unknown to you and you wouldn't find out until you drive. Then.. next thing ya know you're assed out of a rear.

Mr Phil

He drove up here in the car and he has 2 others, alk 3.42 gears he just wants one with a Lil less aggressive gearing for gas mileage. It's the same guy I sold your hood to and plus he's a member on here so I doubt he's a douchebag lol

AmDWs6

so you're saying you are looking for more trouble that you already have?
given the ton of load trying to fix what you got, why bother for the potential other?
3.42's aren't aggressive as one would describe & if he really wanted a 2.73 i really think that any junk yard is loaded with those.

And what i meant is, since you already have a 2.73 there is no wonder or no guessing that later in time you'd be wanting a less of a ratio (3.42,3.73,4.10), knowing that 3.73,4.10 are most likely why even bother with the whole swap thing.

It's just not worth it

Mr Phil

Because I don't plan on going anything more aggressive than that, this is my daily not a drag car. And yes I'm sure he could find one in the junkyard but I doubt the junkyard is going to pay him like I am for it. 50 bucks for his rear and a hypertech programmer is a good deal to me. And it is non tcs so there wouldn't be any other problems.

And you're right, the 342 aren't as aggressive as the 272 I have, but they are more aggressive even if only a little bit and that's all I'm looking for

Just my .2 cents
But I would rather swap a entire rear axle than swap the innards ....
Really no risk unlike the Risk of swapping gears and having a whine which it seems a lot of guys have on here after a gear swap....
If he is the one looking for a higher gear ratio what are you paying $50 and a programmer??
Also not a problem for you but is the other guy going to be alright not having tcs any longer after the swap...

Mr Phil

Ok the is some communication issues lol, both of us have 98 non tcs cars, we are swapping the entire rear end axles and everything. If it was only innards I would just buy a new373 gear kit from summit lol

yes I'm giving him 50 bucks basically for install since I don't have the tools or space at home and the programmer to tell my car I switched to 342 instead of 272

im-not-guilty

iTrader: (4)

Ok I understand the $50
.....but reread what you said about the programmer??
You giving it to home but you want your car programmed for the gears ???

Mr Phil

Yea its the hypertech power programmer 3. I'm getting this with the swap. Currently it is with him, but when we do the swap, I'm getting the hypertech to change gear ratios and then it's coming home with me. ...is that what u mean? Or am I not understanding what u are asking?

I'm confused where you said 3.42's are less aggressive then 2.73... 3.42's are more aggressive then 2.73's is what I think you mean. Personally I wouldn't go any lower then 3.73's... I have 3.90's and I want 4.10's.

Mr Phil

ya u knew what I meant lol... but the cost of this upgrade is minimal at worst so when I do have the cash later on down the road, if I'm looking for more I'll jump into some 410s

AmDWs6

BANG ! right there !!!
do you listen to what you're saying ... think of it this way

by the less mpg you're gonna get from 3.42's with that saved money you'll be able to get a set of 4.10's.

seriously just don't bother.. besides the car is going to be tuned either way and a gear ratio change would be done with that.

i don't know why you're convinced that you want to do it, my brother has 2.73's on his M6 and the computer thinks its 3.73 and he isn't giving one damn about it !

don't spend twice !

Mr Phil

Yea I'm talking in like a year or 2 not in a couple months lol

And how do trick your car into thinking it has a different gear set? The shift points will change right but the gears are still the same so how would it make any difference? It still only has 272 so how would acceleration aspects change? I must be really lost

**** 410s in an auto unless you're going all out. If someone wants to argue with me about it, bring some facts and data to the table.

Ill make this real simple... 342 rear and tune for the 273 rear and 50$ is an awesome and best deal, period.

Why would you swap from 342s to 373? There is no difference in the two. And why would you want 410s for as much as Phil drives his car?

Some of you aren't making very much sense.

And Phil, this is Evan dummie. You sent me a message about the fuel pump... I don't know... 25$ shipped or less Im sure. Text me or hit mw up on fb about it.

Mr Phil

Haha I thought thatwas you but there wasn't enough hostility in your other posts so I thought it might have been someone else haha
