I have a Garrett t3/t04e, with a 4 bolt downpipe. I need studs/bolts to connect the downpipe to the turbo. I'd rather do studs and nuts. Is this the thread pitch I need for the studs? M8 x 1.25 If so, what size nut would fit that? Does the M8 mean 8mm? Isn't that a bit small?

Also, for the feed line, is the threading 1/8 NPT?

Just want to be sure before ordering...thanks

 

Anyone?

 

yes the feed is 1/8 NPT
and yes it should be 8x1.25 for the T-DP. M8 means 8mm, but i dont know about pitch. im rpretty sure M8 is 8x1.00

 

M8 x 1.25

Thats the size i used for my 5bolt t3to4e..

 

Thanks guys What about the 4 bolt?

Would these work?

8mm (1.25pitch) Stud
8mm (1.25pitch) Nut, Locking Head

Yep those are the ones...

 

Thank you sir 8mm seems a bit small lol Time to order up.

 

8mm is the Diameter of the threaded part of the stud or bolt. 1.25mm is the distance between 2 threads.

The 4 bolt may use either 1/4" NPT or 1/8" NPT depending when your turbo cartridge was made.

The downpipe side can either be 8x1.25 mm( 95% of the time) or it could also be 5/16-14 bolts/studs as well.

Just take your turbo to the hardware store and find the right ones between the two I gave you above.

hope this helps, otherwise, IM or email me
