Well, I was attempting to go stage 2 yesterday and started to remove the stock DP, I managed to snap off one of the studs and a second one stripped itself allowing the nut to spin on the stud and not back out.

I'm going to pull the turbo out tonight so I can bring it to the shop at work tomorrow and remove the broken studs. I just called Farifield Subaru, the replacement hardware is crazy expensive. Each stud is 8.58 x3, 2 bolts are 9.25 ea, and 2 nuts are 1.83 ea. Almost $50

Guess you never know what kind of issues you are going to run into when buying a used car. I never had these kind of issues on my old wrx. I rode my motorcycle to work this morning, bout froze my *** off too. Hoping I get this back together fairly quick before it starts raining again.

Anyway, just sharing another one of my stupid car experiences...

i messed up one of my studs when replacing my turbo. think it was overtightened and got cross-threaded. there was enough slack so i ended up buying a hacksaw and just cutting it off. don't know if that is an option for you. if anything, buy the studs and nuts at home depot. much cheaper and there is nothing special about the dealer ones other than the price.

I actually tried some, I think they tightened it on there way too tight.

Thanks, will check into that, prices seemed crazy to me for a couple nuts and bolts, lol.

Good plan!

Dammit Eric, you're a bad influence!!

Thanks Ron! I'll give that a shot, way better price!

Use the OEM studs, Put anti-seize on it this time, use PB Blaster next time about 2 hours before removing.

Use the OEM studs and nuts and they are designed for the OEM turbo and the heat cycling that those studs deal with day in and day out. Others are made of different material and will crack,strip or snap in the long run. Or they will never come apart ever again and they gall themselves into one.

The ones listed might work, But more then likely are made for cast iron heads and manifolds. Not the same as IHI turbos.

From first hand experience they work just fine. In fact I had a guy run these same studs for over 70k miles on the vf39 until I swapped out his turbo and tuned his car. I'm not saying they work better than the oem ones but they do the job for daily driven applications.

Good luck, I had the threads on a nut get munched and Subaru Modesto wanted $10.20 for a single self locking nut. o_O Went to autozone and got 3 nylocks for $2.68

And that has what to offer the OP? Or did you use nylock nuts on your turbo?

The cycling of hot and cold is what is going to get turbo studs. Do it right the 1st time or fix it again later, Costing you even more money down the road.
As for non exhaust type bolts.. Go to Ace for better deals. And make sure you get the right type and grade of bolt or nut.

I can not recommend this book enough!!

I had actually ordered the OEM subaru fasteners before I posted this thread, had to order a intercooler to throttle rubber coupler also. I was mainly just complaining on the cost of parts there days, I buy grade 8 stuff from time to time at ACE here in Vacaville for other projects and they are a fraction of the cost. Still, I will usually spend more to do it right. I bought this STi a couple months ago, you never know what you are getting with a used car. I knew the turbo had been replaced about 20k miles ago, but someone over tightened it and did not use anti-seize like I would have.

Still, from reading your other posts and seeing you experience from your time attack car, I appreciate you sharing your knowledge and experience. Ron, (STINGR5) is a buddy of mine, he's very knowledgeable and I trust him when it comes to subaru's. He's bailed me out a couple times, he means well and was just trying to offer a cheaper priced alternative.



I wish who ever installed the turbo on my car before I bought it had read this book. I only know the basics on a small portion of this stuff, but what I do know is it's important factor, the guy who put this in most likely overtightened it along with the temperature cycles caused them to break when I tried to remove it.
