terrible idea

 

Now that makes 10x more sense than a frakensmission.

But if you're looking to be going over 100mph on a dragstrip, a striped-down f-body will be cheaper than a supercharger kit.

If you're looking to go over 100mph anywhere else... ...unless you've got the autobahn in your backyard... bad idea.

 

I live in NC, and i know alot of local cops and highway patrol. i can get interstates and highways shut down in 15 min intervals, so no need for the autobahn.....lol

i was also told that the autos cant really be modified. i dunno, but thats what i was told. ive doubted the validity of it since i heard it.

to answer the question about how is a 6sp auto better than a 5 sp. since this is my daily for now, extra gear = better fuel economy and higher speed. my buddy and i built a 2000 gt mustang with 646hp and it still got 23mpg. on pump gas.

 

Wayyyy too much trouble for just one more gear. If you're looking for fuel economy and even speed (at least NA speed) you've got the wrong car.

 

wow.....you either have no faith in the car you own, or you have no clue what the car is capable of with some money and wisdom. Give me a couple years, ill show you....lol

 

A couple years.... we don't keep modified cars a couple of years. Your post is stupid!!!
If you can find one poster from the knowledgeable posters ( and their are a bunch) that would change a 5AT for a 6AT I would love to hear from them!!!!!!!

 

Lucas, if as you claim you're a man of function rather than sink all the $$ into some off the wall 6 AT and you still want HP over 100 MPH change the differential gears to a higher gear. If you can find some place to go that fast and you have quality rubber that might be fun.

Actually, I'm quite familiar with my car's current and potential performance -- certainly enough to know that adding one AT gear is not going to magically make it significantly faster or more economical. In fact, if you knew anything about G35s, you'd know a diff swap is a far easier, cheaper and smarter way to go about it. NA you will want to go with a lower (numerically higher) FD for a better dig; if you go FI you will have the torque to go higher (numerically lower) and gain potential top speed.

In NA form you can spend thousands and not see 300whp. It's just not a fast car. The first time you take it to the strip and get schooled by an SRT Neon, you'll find that out. (In case you're wondering, that has never happened to me, because I know the limitations of my car in its current form)

FI is a whole different story. I could be running a dependable 400whp on stock internals, and I personally know guys who are running 650+ with built motors. You can make almost any car fast if you throw enough money and/or DIY skills at it, so by doing that you won't be showing me anything I haven't already seen.

So go ahead, knock yourself out, and after those couple of years you can come back and acknowledge that I was right. I'll be here.

 

FYI, i ran my last project for 8 years, at 683rwhp, and 785lbft of torque. and put over 100k miles on the car......

apparently it has been misconstrued as to what i am asking. I never at any point said i wanted another gear to go faster. I said i wanted to keep the auto for my wifes sake, and the skin on my ***' sake. but go to a 6sp auto for the setup i had in mind. at no point did i imply or state that adding a gear will make the car in its stock form go faster. I simply wanted to know if there was a 6sp auto that will bolt to the VQ engine, or if the 7sp auto will....

thanks to everyone who gave input on the matter, and to the few who decided to bark in an effort to preserve dominance.....go play in traffic....your opinion isnt wanted or needed.

 

Somebody has a very short memory.

I posted nothing that was aimed at dominance, nor any opinions. Just the facts, ma'am, since you seemed to be tragically short on same. Lots of experienced, knowledgeable people told you it was not worth it with this car, but you seem to be hard of listening.

You also said I have no clue what my car is capable of, and I simply refuted that claim. And BTW, I *do* play in traffic.

 

i have read every post, and deemed all of them fair advise, with the exception of yours, im not hard of hearing, seeing as how this is a forum, not a conversation....you must be either a lawyer or a cop, because you pick **** apart and take what you can use and discard the rest. please, save the bandwidth for people that have a righteous opinion, and stop wasting it with your boasts and childish little comments.....ma'am *tips hat*

 

I say leave it alone. In the end, you're going to end up selling the car after all that...

 

While I am now very tempted to go back and pick apart all eight of your posts , I'm not a mean guy as the OG's on this board will attest, so instead I'll help you out a little.

1. Your 'research' will have told you that no 6AT was ever made for the 3.5/3.7 RWD/AWD platform, so you're in tough from the get-go in trying to adapt a tranny from another car completely. That said, with enough time, effort and money, anything can be done. Consensus seems to be, however, that it's not worth that kind of effort. I happen to agree.

2. You might have a chance at getting a 7AT in there, and to my knowledge nobody has done the swap so you'd be a trailblazer and I'd applaud your efforts; you probably have a better chance if you swap in the entire 370 powertrain. Again, JMHO, not worth the effort and the cash you'll spend versus buying a 7AT G37.

3. I'm not a cop or a lawyer.

There, don't say I never did nothin' for ya. Welcome to the board and good luck.

 

Thanks OP, there is a lot of valuable information in this thread.

 

thank you......

yes i did find that they never made a 6sp auto, in my career with building domestics, some of the bell housings are interchangeable, are these nissan trannies the same way?
