low end torque

[pacacu]

own a 91 auto with low miles. want to increase low end torque especially for take off in city driving. car all stock.
please suggest if headers and/or Taitec exhaust would do the trick. Or perhaps need to work on chip replacement.

do they make torque converters for NSXs?

That would do the trick. I saw one once in Hyperrev, but can only imagine the cost.
I think a 4.25 or 4.55 Ring and Pinion would give you a "sensation" of more torque than the other options and improve low speed acceleration. There have been many threads regarding this if you do a search under the gGeneral section for gears.

headers and exhaust will probably do more to hurt low-end torque than help. Lower gearing will help for a moment, but then the moment’s gone. I’m not sure there’s much we can reasonably do to our cars to increase low-end torque other than compressing air into the cylinders in some manner.

You need some of that liquid torque (comes in a blue bottle that goes in your trunk) that Brent uses so well.

Geearing and forced induction/nitrous is the only method that I can think to improve low end torque on a smaller engine like the one in the NSX.

The exhaust modifications you mentioned (exhuast/header) will only give you power in the mid to high range, as DanO points out. The restrictive stock exhaust system increases back pressure assisting with low end torque.

Try giving these guys a call. They may be able to do something with your tranny. Perhaps bump up your stall speed a bit.
