fireballs gs400

Would like to buy a lsd for my 99 gs400 and a t/c from p.i. Any ideas on someone with a used one in good shape. does steve still offer these at the best price possible. I just don't want to buy something and not really be happy with it. the t/c would be great. still up in the air about the lsd, anyone with these sitting around.

I will be putting my RMM lsd with the 3.76 gears up for sale in the very near future. Pm me for more info if interested.

Thanks

since your 400 is getting a s/c, why change? is there one better fit for the blower?

From what I understand, the 3.76 gearing in the RMM Diff. is geared too low for a FI GS, supposedly the car will hit the rev limiter due to the lower gearing. Without FI, the gears are great in the car. This is all hearsay, I will have some personal experience with it shortly. This is why I havent put the diff up for sale as of yet, It might work fine...I will see soon.

From what I know, the 94 Supra TT uses a 3.76 gearing. I'm getting one of those for my setup when I put on my FI kit. Or you could go w/ a TRD LSD w/ a 3.27 gearing but you'll have to wait 2 months to get those from Japan. That's what Steve told me.

Cong, your exactly right about the Supra TT rear, it is 3.76 gears. Hopefully what I have will be fine with the 3.76, we'll see.

With the PI TC and an LSD which retains stock gearing, I can easily roast my tires from a stop. With the 3.76 gearing this is an even easier task [RMMGS4 has this combination]. With the extra torque that a SC or Turbo provides you will find yourself extremely traction limited. And with the wider powerband, the stock gearing is a better fit. But there's no real harm in seeing how it works for you -- you may enjoy roasting your tires at 1/3 throttle.

Hmmmm...as much as these 20's cost, I dont think so!!

Actually, that is something I had not considered. I am running ultralight 18's [bit over 16# per corner] which helps. If you are running [heavier] 20's perhaps the 3.76 gearing would be ok. And my understanding is that the problem with the rev limiter is marginal -- since the diameter of the 20's is larger than the stock setup, perhaps the rev limiter problem won't be a problem.
