Too much propoganda and rhetoric in that.

Basics about LSD.
It tries to prevent one wheel from spinning more than the other.

LSD does NOT integrate with the transmission unless you have a transaxle.

LSD does NOT sense anything. A series of clutches or viscous fluid (depending on the type of LSD), keeps one side of the diff from spinning more than the other. The more clutches, or the thicker the fluid, the less the chances of one wheel spinning more than the other.

As long as the driver can keep both wheels in complete traction, then an LSD will be of no help to him/her. Just like ABS and braking. ABS does not make a car stop faster. A good driver, modulating their own brakes, can stop just as fast, if not faster than the same car with ABS. What it does help is for panic stops when the driver isn't experienced enough.

And a car with a lot of power, an LSD, and an inexperienced driver will be more than twice as likely to spin the rear end of the car out while applying power coming out of a corner.

 

You missed headers on there. Dyno is SC430 section. Also not sure how many here have done all of the mods to actually know for themselves which works best.

Preference as I have had/do have these on either my SC or GS4

PI or Dragon Torque converter. Much better drivability as well as launch.

LSD/3.76-Better launch for hole shot and power to the road. Thing is you should have this if you have a TC for traction. Just watch the wet corners.

SRT/ECU and Headers-I would do both at the same time.

You have a lot to learn youg grasshopper..No pun inteneded. Other guys can chime in

 

Since I had done all of these things, I can personally say that the TC is the best bang for the buck. No it will not give you more HP, but you can get into your power band much faster since the motor will rev "freely" until lockup.

SRT will give you some ponies, but I have noticed that a good aftermarket filter, I used the Tom's one (from Steve Ganz) and noticed that I had felt more torque on the bottom end than the SRT with the ECU.

LSD would help more with handling of power on hard turns and acceleration from a stop. I have yet to see a NA GS3/4 break loose on a dry road at 20 mph in a straight line.

That being said, if you can get a TC and installed for under 1200, I would do this than spend 500 on an intake.

BTW for those who are interested. I did race my friend who had an SC'd GS4 at 6lbs of boost without an upgraded TC. I had a 3.76 LSD, intake and TC 2800 stall. I beat him off the line, up through 2nd gear and he finally past me when we hit 60 mph. He was upset because he actually got a jump on me but my gearing and TC helped me get to the engine's sweet spot faster. NOW........................no competition, I'll give him the smackdown even with him having a good jump on me. My snails make up for my snoozing

 

Please correct me then. Sorry, I'm new to the GS. But I'm not new to RWD or cars. And the workings of the differential (open, CLSD, VLSD, or locker) don't change because the car changed.

 

So the SRT alone will not improve 0-60 and quarter mile times. LSD would help more with handling of power on hard turns and acceleration from a stop.
"I have yet to see a NA GS3/4 break loose on a dry road at 20 mph in a straight line."
That is what I wanted to know, because I usually encounter some happy go lucky at a stop light that wants to race. I can tell you that with this LSD, I hung with a 05 Mustang Auto.https://www.clublexus.com/forums/sho...d.php?t=199731 Guess the next mod will be a TC to go along with the LSD.

 

Let me make sure we're on the same page. I have yet to see an NA GS 3/4 break loose from 20 mph on a dry road/straight line regardless of having an open diff. Of course an LSD would be even harder to break loose.

TC will definitely help 0-60 times much more than any intake. Unless................. at the other end of the intake is a blower or a couple of turbos

 

It will help both, just not like a TC will.

 

Don't worry about any of it. Some people have their thought process locked in and do not want to learn.

 

yeah if money is not an issue when it comes to paying for labor i would agree with Hi98...

The TC is gonna let the car jump or rev up into the "sweet" spot much faster... that would be the ideal mod if you want a quicker jump off the so called line. LSD just allows the torque to still go to the wheels even if one of them is slipping in lament terms, as AZ-GS300 stated.

 

[QUOTE=AZ-GS300]

Disagree with this statement. So what is the purpose of the drive shaft in our cars?

 

Hmmm I'm inclined to agree with AZ, the TRD LSD doesn't help at all with accelleration, it helps with traction. The 3.76 gearing in the RMM / Supra TT Torsen LSD will help with accelleration. Only if your GS is 'hot' enough to have traction problems or on bad surfaces where you lose traction will the TRD LSD give you a better 0-60 or 1/4 mile time.

I added the TC to your poll a bit earlier, and that definitely gets my vote for biggest bang for the buck.

But the gist of this thread is to find out which individual mod gives the best bang for the buck. I am seeking opinions from members who have or had these modifications done. That is all. In your opinion the TC is the best bang for the buck. Great. I would like to hear more guys as well.

 

[QUOTE=DASHOCKER]Exactly... we've had plenty of posts for biggest bang for the buck (but not a poll, great idea ) and the TC is nearly always named. I just don't want to have a post out there with info direclty opposed to what I've observed / learned on what a mod might do for performance without saying something to clarify

As you say I have (or have had) all three of these mentioned, TC definitely wins hands down for me.

[QUOTE=DaveGS4]LOL, even in 2002 you tell guys to use the search option I see that the TC is the best bang for the buck.. That will be the next mod to make the GS "hotter"
