So i just bought an NRG ETD and i believe i am missing a bolt as there are only 2 which must be for the ETD itself. What size bolt is used to mount the small bracket to the engine?

Thanks in advance!

 

No one feels like pulling that bolt off quick?

 

I took a look at a pic of it and it's very possible that you use existing bolts that are on the car.

 

If that is true i am missing the bolt on my engine or i am trying to bolt it up to the wrong spot?

I am almost positive i have the right spot..

 

thats the right spot. i thought it was a bit strange too, i got my nrg damper off ebay, same thing didnt come with that bolt. i ran down to the local hardware store, its an M10 bolt. I bought the shortest one they had (M10x16 i think?) but the threads arent very deep so try to go with something like M10X12 if that exists. also buy a washer/spring-lock washer for between the bolt and the bracket.be careful wrenching the bolt into your block too. even though i tightened mine down as hard as i could, after 5 minutes of driving, the bracket had shifted to one side so that it rested somewhat on the exhaust flange. this is a pretty shitty design imo, the bracket doesnt seem very solid but oh well i havent had any problems with mine yet

 

Thanks Jbird,

That just makes me wonder wtf is that tapped hole really for? lol

 

idk i thought that too.

 

I believe Billman told me once that the threaded hole is for an engine hoist to remove the engine from the car.

 

Well that is a fun little fact. Thanks for sharing!

FYI i measured the depth of that hole and its 25mm. so it would probably take a 20mm lg bolt seated flush but when you have the flat washer lock washer and .19" thick bracket a 25mm long bolt wouldn't be a bad idea. I will purchase a few bolts after work and try them out and report back to be 100% on it.

Thanks for all the help everyone, s2ki never lets me down!

 

how did you measure it? it may be that deep, but is it threaded to 25mm? i went for shorter, because after the first few threads it becomes very hard to turn as if its bottoming out
