What is the best way to make the automatic TT perform better? I was thinking of torque converter or maybe just the 4.10 gear. Is it overkill if I put a 4.10 gear and a 2500-3500 stall converter? Which one would give me a better peformance if I have to pick only one Opinions please!!!

 

First thing I would pick up is the HKS ALC-II, that would be the simplest improvement.
Performance would also benefit from suspension upgrades like subframe spacers and ES bushings.
4.10 gearing and stall converter aren't neccessarily overkill. I'd say it depends what "better performance" means to you and how far you wish to take it.

 

two words... "manual Convertion"

 

Or the paddle shifters now available...sweet. I'll be damned if I can recall who was selling it though. I believe that set up was in the $1100 range.
I'll hunt it down tomorrow.

I want to lower my 1/4 mile times. I want to get into 11's using a stock auto. I think a 4.10 & 3000 stall would be a good combo. How strong is the stock auto tranny?

 

The HKS ALC II well be your best bet. The RE4R03A Nissan automatic is a tough transmission but it has soft gear changes and by installing the HKS ALC II you'll increase line pressure but also make the shifts chrisp.

In your first post you asked for ONE choice, now your asking about multi-choice.
First the final gear ratio of the N/A rearend is 4.08.
To get your car into the 11's is going to take a little more than a rearend change, hi-stall torque convertor and a HKS ALC II.
As been pointed out you'll need to do some suspension upgrades, tires and engine work. An 11 second car is going to cost and won't happen with 1 mod., but it's very doable and you have the right car to do it with.

 

damn, those F1-style paddle shifters are so cool!!! too bad their so much!!!

 

I think the 4.10 gearing from Leader Gears would give you a nice improvement in acceleration. I have read some testimonies from people on tt.net that have installed them and they say that it feels like a whole different car. They are $710 from Specialty Z and would be better than swapping in a weaker N/A rear. http://www.leadergears.com/site/content.php?content.5
A torque converter would help as well.

 

those geaers say "made in the USA" that dosent sound very JDM to me guys. Iono but i don;t trust us made parts in JDM cars.

 

manufactured in the usa... parts from china i bet!

 

I'm putting in a GT28R his summer including all the supporting mods aka: injectors, intercooler, boost controler and the rest of the mods that I have already purchase. I want to do something with the auto transmission while the engine is out. I have a little over 1k left for my project. If I can get both the 4.10, stall converter or HKS ALC-II. I would be happy.

 

Who cares? "JDM" gets overhyped. The gears are well made, otherwise Greg Dupree would not sell them.
