another happy 3.76 LSD mod
I read the nudderGS400 thread and felt that I may as well go for it. The RMM people did not have one and were not sure when one would get in. I called Carson Toyota and they had one in stock ready to ship and for 300 less than RMM.
Bell Lexus in Phoenix installed it and it is worth it. My '03 430's low end torque has woken up. I don't feel like I'm dragging an anchor when I leave a stop light. The car is perfectly drivable in city traffic. The RPM's are higher but that seems to make acceleration alot cleaner at any speed. Put it in "4" instead of "D" and it really, really goes.
I'm convinced that the original GS was probably what we all know as L-tuned and with the 3.76 LSD. It drives like a Lexus luxury car, but with extreme performance compared to stock.. My theory is that the marketing guys told the engineers to undo some of the performance for the sake of preserving the luxury image. It's just too much of a concidence that all of the parts are so readily available from Toyota.
Since it occasionally gets a little warm in Phoenix during the summer, I'm a little hesitant about a torque converter and a cooler. But what can I expect if I do it? I have stock 17 in wheels, Eibach springs, TRD shocks and TRD sways.

It sounds like a no brainer mod for all those more inclined towards performance!

What can you expect with the PI TC? How about shorter tire life? LOL Actually the LSD will have preserved tire life some which is good.
But the PI TC will improve launches still further, but even better it makes downshifts smoother which makes passing better.

I don't know anyone who has done this, I've asked before. There is an SC430 member that has done the swap into his car with no problems.

Congrats Presto
Glad I didn't steer you wrong, always a worry when you post your own impressions. Everybody is different!
I still smile when I drive mine everyday.
About the TC, for me, I will pass. Until I hit closer to 200K or so on the odometer and need to do some tranny work, then I probably will change the stall speed. (The previous owner was not informed of the importance of changing the tranny fluid.)
If you love the new acceleration, and want another full dose, go for it!
Enjoy your ride.

however like dave and i said in the other thread, if you want blower later, don't get the rmm, not good
you want others like the trd. but that's very hard to install and very labor intensive, costd A LOT more to install
