Studs vs Bolts

[Jet Black]

Working with the studs in the T3 turbine housing is proving to a be a real pain in the ass (never mind that the unit itself is older than me). I was wondering if its possible to replace the studs with bolts?

Thanks.

the studs should just be screwed in. On stock 14b turbos there is one stud that is screwed in which you can replace with a bolt. Much easier to work with 4 bolts then 4 studs. Grab onto the studs with vice grips and see if they unscrew.

NICE! So I guess Im mos def going with bolts (Steel grade 8+). Ya I tried the vise grips, though my next option is to drill a hole...

when replacing studs with bolts be sure to use some high quality anti sieze, otherwise your bolts can break causeing you a huge pain in the ass and downtime until you find replacements.
for turo's and exhaust manifolds, use a antisieze thats nickel based. its designed to take the high temps and abuse of the turbine inferno.
and make sure you use hardened bolts too, the hardest you can find to prevent breakage, of course you want to be the hardest for a reasonable/acceptable price, i'm sure you don't want to pay 40 bucks for a set of bolts.
good luck

its also a very very good practice to spray antisieze in the threads and chase the threads with a tap before reinstalling bolts, that way you get the most available torque, makes new bolt thread easy without damage to them, and get all the previous oxidation out to offset corrosion of your new bolts.

Ya I plan to *attempt* to clean out holes before I install the bolts. I'm going to marinate the bolts/studs in anti-sieze before install as well.

Now I just realized that I might run into some problems with using diffrent types of metal. The problem comes in with thermal expansion, I'm not sure how the super-hard steel bolts will react with the cast iron housing.

Should I use some sort of washers for this case? Or is this a non-issue?

Thanks again guys.

Copper grease is the best anti-seize you could use for this.

the stock turbo setup uses washers. i would rcomend them on your setup as well.
