I personally have never tapped anything thing on a engine. So i need to need to tap my block on my lsx block for ls1 style sensors since i am running a ls1 wiring harness. Is it hard tapping the block or should i have someone professionally install it for me? The lsx block has m8 theads and the ls1 has m10 threads. Can i use any kind of an adapter instead of tapping the block or is there a ls1 sensor with a m8 style thread?

 

just drill it and tap it

 

well i know the other option is using the motor mount holes. Could i use on of the motor mount holes where my motor bracket is? So it would just be like a 4th bolt ?

 

come again? use the knock sensor as a 4th bolt? Just drill and tap the block. It's not hard.

 

Figured it out, ended up not tapping the block too!

 

how'd you do that?

 

Talked to my tuner first but, i put one knock sensor on the rear engine mount hole, and the other in the front side mount hole. Appears that on the lsx block you can mount your knock sensor towards the front of the block or the rear of the block. i know what i am saying sounds confusing. i will take pics of my car in the air monday, when it goes to the exhaust shop. Just finishing my engine swap.

 

cool, interested in the pics.

 

any pics on how you did it yet?

 

not yet, car is at the dyno shop..

 

just tapped my block, nothing to it man.

 

No need to tap the block. I had like 5 bolt holes to choose from on the passenger side because I'm not running AC, and 2 on the driver side. Screwed them both right in.

 

ya i forgot to mention i am not running a/c so ya same as runner like 5 different bolt holes to choose from.

 

haha, that made me laugh.


I had a hard time finding holes. My Kooks 2" made all but 1 M10 a no go...

but like said above... i just drilled one a bit bigger and I was good to go. no big deal.

jk. it was a big deal to me. I was a scaredy cat. That was an expensive motor.
