is that an ATS TB inlet? looks nice. i ordered one last week!

Yup, I ordered that and the GM Knock Sensor Conversion for Doc to install. Along with the healthy dose of goodies that he's putting in the car.......should be really niiiiiiice.

i woudlnt recomend using the GM knock sensor. it dosnt work correctly for our cars and ats should stop selling it imho. keep the stock sensor.

And another thing . If GM sensors are narrow band sensors, then why can I loosen my valve lash and create knock that gets picked up by the sensor??? Why can I swap from a stamped steel rocker to a full self aligning roller rocker and get knock?? Why can I have a long tube header merge collector tapping on a crossmember and cauing the knock sensor to do it's thing?? Why do you have to completely disable the knock system when converting to a solid roller valvetrain? You can't possible say that the knock sensor will only pick up on a single frequency based on the bore of the block when so many outside the bore items will set it off.

Look at this. Where does the knock sensor install?? I don't know for sure about the 3S-GTE, but on ALL GM motors the knock sensor installs into a water jacket. WHY?? Because the knock sensor pickup will be always submerged in the coolant which makes an excellent transmitter for various knocks that occur within the motor. Hence, I don't see HOW the knock sensor can only pick up on a single tuned frequency. Support for this again is shown in the above paragraph.

You guys are starting to beat a dead horse with this. You're not going to change my or Doc's opinion on this. It's my motor, I'll do what I want. I took your advice with due regard, and made what I feel is an educated decision based on what I've seen from testing and real world use. Fact of the matter is that I'm sticking with the GM knock sensor because I feel that it's an adequate alternative to the overly priced OEM Toyota knock sensors, and that decision isn't going to be swayed. I know that you guys are watching out for me with what you feel is the best thing, and I sincerely appreciate that.

That said, if my motor ever grenades due to the gm knock sensor not doing it's job, I'll sponsor a meet or something (food, beverage, coordination, ect) and publicly admit I was wrong.

That's what these forums are for, right?? I'll pony up and be the classic example once in a while.
