Hi All,

Looking for some input please.

I’ll be installing my inlet and downpipe soon along with upgraded TSP titanium studs. Stock turbo will remain (for now - at least a year).

My question is:

Should I upgrade the studs from the turbo to the engine as well while I am there or will I be fine later on when I decide to replace the turbo?


My thought is that if I leave it be for too long it may seize and I should just do it now. Unless i am overthinking it and I should just leave alone.

Note: I do not daily the car and will likely only put a couple thousand miles a year on it.

Thanks in advance for your thoughts on this.

Since you are leaving the turbo stock, and you are eventually going to upgrade, I would just wait until you have the turbo completely removed. That way, you have a lot more room in there to use the proper tools, and you do not encounter any binding. There always runs a risk of cross-threading or other issues if you are not experienced when more and more things are in your way. But it is doable.

I may be a bad source of information because I went from 100% stock to a notch under beast mode with 3000 miles on the odometer. I stockpiled all my parts and did the full install at once, taking my time. ((Not my daily)) Which is still underway (90%) complete.

Thanks for your feedback. Did you run into any issues with the turbo to engine studs?

Personally, no. They came out like butter. But my car has only about 3000 miles of light driving.

If you aren't pulling the turbo off, I'd just leave them as is for now.

I cannot say I've ever seen a report of those studs snapping.

Per decades of aerospace experience, titanium is a very poor choice for fasteners (unless weight is everything). Ti galls easily, creeps loose, and most Ti alloys aren't good beyond 600degF sustained.

And we were using certified aerospace traceable, USA sourced titanium, vs. eBay Chinesium Ti.

Are you implying that all Titanium studs that have been advertised to be better than the stock studs are actually not?

I appreciate your expertise, but do you have data to share?

What would you recommend as an alternative?

Ti is an awesome material due to high strength per weight. Excellent for aerospace structures, but not for fasteners per my above comments. Also Ti isn't as strong as many fastener alloys. I don't know what alloy Honda uses, but common grade 8's are stronger. More exotic nickel and corrosion resistant steel alloys are stronger and more heat resistant too. Ti degrades at turbo exhaust housing temperatures.
I won't quote numbers, but you can research the basics on the web.

Thank you for your feedback. Will look into it.

I can tell you what is better about our titanium studs: They install easily, come off easy any time you need them to, and look great in the process. My FL5 has endured a dozen or more turbo swaps as it is our R&D test mule along with being my daily driver. A factory stud snapped with only a few hundred miles on the car during our initial downpipe install. Ever since the titanium studs were installed, it has been a breeze anytime I've ever needed to remove them. My use case is not typical - most people will not be taking their car apart and reassembling it on a regular basis. However, if it holds up to what I throw at it, it should easily handle any of our customer's needs. Don't forget the 250+ dyno runs, multiple track days, and all the heat cycles associated with that.

We have not completed any lab testing and I'll admit that we don't see a need to. They simply work great for this application. If we were flying airplanes, a deeper dive may be warranted. 🏎

Thanks for chiming in on that and providing your thoughts. Never had any doubts on using them on the car, but certainly interesting input regarding aerospace applications with Ti hardware.

Glad to help! I certainly do not mean to imply that lab testing is wrong, just that for our application it has proven to be a great option in real world use. 🏎
