Why?

Risk of galling and possible galvanic reaction I would say. Most stainless isn’t as going to be strong as good carbon steel fasteners either.

Or "Why Haas ST15 with a bar feeder and a parts catcher to make titanium bolts?"

Because he can!

Basically, stainless fixings are almost always much weaker than steel fixings.

Stainless shouldn't be used with aluminium due to galvanic corrosion.

They're OK for non-structural stuff if you really want but they're basically st.

PPBB, where does one procure titanium bolts from and how to you measure their strength against SS ones?

Haas ST15 with a bar feeder and a parts catcher is my go to procurement device.

... and if one doesn't have space for such a beauty in their workshop, is it possible to buy them somewhere at non-stupid prices?

hahhaha Indeed, I want to replace as many of my exterior (subframe, wheel bearing / hub holders) with titanium if possible.

What year is the car? Did it originally have a secondary air pump?

If it did, and you removed it, how did you get around the CEL light?

Any details appreciated!

Probolt will do most things off the shelf in Ti, however many grades of Ti are not a suitable material for some fasteners unless you want to life them like you would on a race car because it will work harden. AN/NAS bolts are a good go to but they are imperial for the most part. It requires a bit of engineering work to replace one grade/material of fastener with another to ensure the life and strength remains in an acceptable window.

It's a 99 as such it's one of the rare ones which is DBW throttle with all associated electronics but isn't OBD2 compliant despite having a standard OBD2 port etc. It's perfectly happy running with no Lambdas, SAP or similar and won't show a code for them missing as it doesn't monitor emissions devices like an OBD2 compliant system would.

Just a quick update to say it's in the paint shop. Porsche galvanising from this period remains mighty impressive as it's done 18 winters of salt and wet without much more than a bit of surface in a few hidden areas.

Everything is being done bar the roof and engine cover which were in decent condition to start with.

Really looking forward to seeing it back in its former glory and ready for another 20 years of taking stick

What's the current mileage?

Love following the progress of this car. I’ve literally read through all 36 pages and it’s given me a new appreciation for the 996

[marine boy]

read this thread from start to finish last night

what a lovely car and put to such good use, I applaud your taste and execution

don't mind me asking OP but which F1 teams have you worked for?

[Paynewright]

PPBB,

Are you still pleased with the Oz wheels - thinking of getting a set?!

Can we have pics of the respray process?

I put some of the cheaper OZ on my 997 as my OEMs need a refurb. The fake centre locks are a bit naff but the wheels are great.

Dup post!!

Yes very, they have proven to be super strong as well as light - a combination that doesn't happen that often!

[poppopbangbang]

Well that looks a little less used.....

[jonnyconnor]

Wow! Very impressive, your car looks great! Will you still be using it for the same purpose now that it’s got brand new paint?

Absolutely! The paints only there to stop it going rusty
