What is the best knock sensor for my application?

1G, 2G or Evo knock sensors are all tuneable. The 1G is much quieter though, which can be good and bad. The Nissan knock sensors on the KA24 and SR20 give low readings similar to the 1G. I am not sure how a Honda knock sensor would work on a DSM, the B-series Honda knock sensor usually max out from engine noise well before revlimiter, but those motors have a lot of valve train noise. The S2000 and NSX knock sensors work good, but cost $$$. I have tuned MR2s with the AEM EMS and GM knock sensor and it seemed to work decent, the voltages it puts out seem to be pretty high like a Supra knock sensor. You can get a generic Bosch knock sensor for probably $40-$60.
