50466, manifold studs too short
Posted by hkillr, Jun-13-03 10:19 AM
my cars been in the shop getting my custom kit installed. when they went to bolt the turbo to the manifold the studs were barely sticking out, just enough to get the bolt started, but not enough to hold. has anyone else had this problem. the guy at the shop says he'll have to take the mani off and somehow put some longer bolts in it. i dont see how this can be possible, its a gottude mani and its all welded. any suggestions or help!!!!

I pieced mine together from what is availiable at McMaster Carr. 18-8 Stainless studs, washers, and nuts. $18 for the hardware, with nuts and washers to spare.

Exhaust studs 8 Metric 18-8 Stainless Steel Full Thread Stud M8 Size, 40mm Length, 1.25mm Pitch McMaster Carr 93805A359 10.40
Exhaust washers 100 pack of Metric 18-8 Stainless Steel Washer - DIN 125 M8 Bolt, 8.4mm ID, 16mm OD, 1.4mm Min Thickness McMaster Carr 93475A270 3.38
Exhaust nuts 50 pack of Metric 18-8 Stainless Steel Hex Nut M8 Screw Size, 1.25mm Pitch, 13mm Width, 6.5mm H McMaster Carr 91828A410 4.41

EDIT: oh yeah...I installed them the other day - to install my Bosal header. That thing has a THICK ASS flange on it...so I think 40mm studs should do the trick for whatever your bolting up.

the machanic didnt want to , he didnt think it would hold up to the pressure, he thinks he can replace them with some longer ones. i dont see how.
