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.

Fastbird and Doc:

Your logic escapes me here. Please explain why this statement from Justin does not concern you:

If it can be used to "fix" a knock problem it can let that same problem exist where a stock knock sensor would alert the ECU.

It can't be used to fix a knock problem. It never was intended to either.

QUIT PLAYING WORD GAMES! You know the word "fix" was in quotation marks. Justin wasn't saying that the GM sensor could fix a knock problem. You know that. The question is: Why aren't you concerned (based on the information that we have all now read) that the GM knock sensor which is designed for a larger bore cylinder will not pick up some knock and possibly result in engine failure in a 3sgte?

LOL! Maybe I should have italicized the word "fix" as well. Thanks for clearing that up Jay.

Yes, I am using the GM knock sensor because I know that it's harder to blow. Think about this: You're running the car hard without a datalogger. You start to get knock that you can't hear audibally, and it's working as advertised. Then the OEM one blows and before you have a chance to react (you're still in the gas) the knock continues and you pop a piston. I'd rather have the GM knock sensor in there with it's ability to take a bit more abuse than the OEM one.

This is turning into a pissing match more than anything. Obviously the OEM sensor works, and the GM sensor is proven to work also. Some like it, some don't. Leave it at that, and let those who choose to use the GM sensor use it without the condascending statements like "It's your motor" or what CelicaSTX02 said.

Ever consider the fact that the GM sensor doesn't blow because it's not designed to "hear" the same frequency the Toyota sensor is.
You know that the knock sensor blowing puts the car into low boost mode right? Blowing the sensor will not alow you to continue knocking. It is a safety feature built into the Toyota ECU. If you have knock severe enough to blow your sensor there is obviously something wrong and it puts the car into low boost mode. That is, if you still have your T-VSV connected. If not you should at least have it wired to a light so you know when it's being activated by the ECU. Again, all of this is covered in the post that Jay linked to at MR2OC.
