Trying to find the bolt size and pitch for the T3 Turbo flange on pfabs elt top mount Mani. Emailed pfab but haven't heard back.
Thanks

 

Most T3 flanges are tapped for M10 x 1.5 studs/bolts (otherwise, they're likely 3/8-16)

 

I have a similar question. What bolt size for the T4 flange for the pfab elt top mount?

 

Yeah just picked up some M10 1.5 but they don't really want to thread in. May have to run a tap.

 

I know inline pro manifolds are 10x1.25

 

My AFI was 3/8. If it isn't installed on the car, take it to the hardware store with you and size it. Best way to know for sure.

 

I tapped them to m10x1.50 the holes were already stripped at the start of the threads so I just retapped them to this size. Will also run a nut and Nord lock washer with them.

 

i believe they were 3/8th. the one hole is hogged out because they idiot at the hardware store gave me stainless bolts when i asked for grade 8 and guess what fused itself to the manifold when i had to take the kit off to do something.... yeah you guessed it

 

Yeah I saw that. Tried a 3/8 also didn't fit. The bolts in it were wore and the threads were rounded. The m10 tap worked should hold good with the 10.9 m10s and the Nord locks

 

I got a pfab manifold too, T3. The M10 bolts didn't want to go in. I had to tap them all.
It looked like only the first tap was used.... 2nd and 3rd had yet to be done. Bit weird.... but it works fine now.
