I'll do my best in the coming weeks!
Awesome!. I bet the car sounds amazing when that turbo spools up.

Hi, Just wondering if you have had any head gasket problems with those raceware head studs? I'm interested as I would like to use them myself to prevent any stripping of the threads when torquing down cylinder head. ESS have stipulated in another thread that on their TS3 build the only head bolts that were reliable were OEM ones. The Raceware studs couldnt keep the head seated firmly on the block and caused some head gasket issues. What did you torque the head down to? Due to the stretch design of the OEM head bolts I'm not sure that using the same torque sequence with head studs would create the same surface pressure between the mating surfaces.

As far as I am aware no one has had any issues with raceware studs. IIRC there was someone making close to 500 whp with them. I am using them on my build with no problems so far. Don't forget to re torque them after a few thousand miles.

Thanks, I was just asking since ESS quoted that when they used studs on their TS3 kit the head kept lifting and the only reliable fastener was the OEM head bolts. I would like to avoid OEM head bolts as I have a real sneaky feeling that the threads will strip when torquing down, although the engine has never been overheated. I imagine that it's much less likely to strip the threads when using studs as the stud is static in the thread in the cylinder head. If I use head studs, is it the same torquing sequence as BMW recommended? Also, since the final torquing stage is 90 degrees angle tightening, how would I torque them down again after a few thousand miles? Without a final torque figure due to them being angle tightened, then how would I know what to retorque them down to?

Thanks

I don't recall the exact torque specs, was awhile ago I put this car together but I believe it was around 85ftlbs in 3 increments. Have had zero issues so far. I've seen what stock head bolts do on stock motors let alone on an FI motor, that sounds like the most unintelligent recommendation I've heard

This car is making 430whp through the auto, on a manual we'd be near 500whp with this setup now. This car will see more boost in the future and 500whp though the auto trans

When you buy any of these aftermarket fasteners they will come with directions in the box of torque sequence and spec, not sure why you're worrying about it now?

The Raceware studs also use larger threadserts giving even more grab in the block, also extra machining and complete engine tear down to install.
