5th gens have equal length drive axles? Now that you mention it, I don't remember my wife's 5th gen having much, if any, torque steer at all. Of course, it's completely stock, probably about 100hp less than my 95.

Um, not quite.

Hmm... now that I think about it, that's pretty much impossible that the drive axles could be even on each side. Then how would you explain the lack of much torque steer?? I don't know how Nissan pulled it off but my brother's supercharged 2K1 doesn't pull to one side at all, even when he's spinning out. FYI, he has no LSD.
Edit: Not quite what Mr. Moderator?? I hope you're not talking about the small amount of torque steer because that's a fact. If your talking about the axle business, I corrected myself.

this may sound funny, but drag radials do not help me in any way. I don't remember what brand or whatever i had used, but I was able to pull 2.2 or 2.1 60's , which is same or worse than I pull on my stock tires. I was thoroughly not impressed.
jeff I think jason should try a new tire/wheel combo bc sounds like you have some nasty traction issues.
I don't really struggle too bad with traction - I mean it could always be better, but I am on all-season 400treadwear rated tires and they hook pretty darn well! as mentioned, in first gear if im going from low rpm and floor it, it wont even break traction.
Also, torque steer practically does not exist on my car, and as of a couple weeks ago I am back to a non-LSD tranny, and still no problems. I was able to pull 2.1 60' on 4 of 4 passes at the track (would have pulled 2.0's everytime except I didnt want to slip+tear my clutch anymore)

So you don't like your kit then? 
This discussion has happened many times. Because of the torque the VQ engines produce low in the rpm range even without boost, traction can be a problem. Once you hit boost ... goodbye traction! If you are breaking tires loose in third raw power has something to do with it, the other is if you have an open diff. The LSD I put on mine made a huge difference! No more torque steer and no more peg-leg burnouts!
Back to the original question though, I must agree with several others that the T3 spools quick and you feel fast whereas a T4 takes time to spool but makes bigger power. Maybe we should have a poll of how many people have T3s and how many have T4s, Granted there are so many trims, A/Rs, Ball bearing etc but it might be interesting!

So in my opinion, the larger turbo gives you time to get going before the boost fully kicks in, and when it does, watch out lol. A smaller turbo does reach full boost faster (in most cases), but I need the traction to at least get moving....

And you are still breaking traction in third? Dayyyyymn! how much boost R U runnin'? My boost controller is acting up again so I can't get past 9 psi but it is still fun!

Fully Clutch based with 800lb springs I think is the correct nature of the beast, true 50/50 with no zero effect. Full race warranty. So, even with the LSD diff, I am still breaking loose in 3rd.

How heavy are your rims? They look HEAVY, if so, that may be why others with light rims are having traction issues and you're not.

and I had even worse traction on my heavy 18's w/ 245's...
that is why I suggested trying a different combo
traction can be controlled.
