I do not know about the rest of you, but I certainly hope that the Swift-Racing products do what they say. I see in the performance forum the RMM intake has caused some problems and decreased performance. That would be a nightmare! I would be willing to spend some $ to upgrade the performance of the my beautiful IS, however proven HP gains, reliability, and voiding the warranty are concerns of mine. Swift-Racing certainly seems knowledgable and dedicated to the task, but talk is talk, anyone have any information on this company?
Thanks!

I know a lot of people who have used swift-racing parts on their lexi's. And they do and are proven by Dyno's that they really work. It isn't crappy ass rod millen that doesn't prove anything they make. Don't know why or is it just for show.

Hey GSnav, I have heard good things about the torque converter for the GS. What do you think?

I just picked up a G4 so I was referring to it instead of the IS. The problem is that I'm in Dallas and I worry about installation.

I have to ask, Why does brad get special prices. I know I sound like a 4th grader. Seriously though. I am interested also. I have noted my concerns. I am sure you are a very reputable operation. But, I am also a cautious and frugal individual. Looking forward to positive news!

Does the upgraded torque converter retain stock-quality shifts, or do the shifts get noticeably harder/harsher/less smooth?

And I will assume that it will fit in the IS300...

I would assume that it would be less smooth... Lexus loses a significant amount of power to smoothness.....

I wouldn't assume this actually. My understanding of a tourqe converter is that it acts like a like a clutch off the start. It just raises the RPM that the transmition is engaged at off the line. Other than that it does not affect the other operation of the transmition. You can hold the brake and build rpm's higher at the start than you can currently. Like droping the clutch. This is my understanding from my much younger drag racing days.

So if it has no real drawbacks as far as smoothness is concerned... Then why don't manufacturers use more aggressive torque converters to begin with?

That is a good quesion. This is my guess: It might not be as smooth off the line due to the increased RPM and that it might adversly effect MPG, a definate concern of the automakers, but thankfuly, not aftermarket performance suppliers.
I am no expert, and this is just a Hypothesis (trying to use big words to show I am educated since I know my spelling says otherwise). I am hoping that Swift can provide more details on this question

Yes, I am sure that fuel mileage is a major reason why the stock torque converter is like it is.

Also, a higher stall speed torque converter would make it a little harder to "creep" along at very slow speeds as many auto-trans users do in slow traffic.
