New head finished for a 2019 Hyundai Veloster N with a full complement of Supertech and GSC parts. This started as a brand new casting but still went through our complete process to ensure the quality was up to our standard. As I’ve mentioned before, these heads are very similar to the Mitsubishi 4B11-T as they were codeveloped.

Hyundai Veloster R head cleaned up and ready for machine work. This was actually a new casting from Hyundai but it is still going through our standard process to make sure nothing is missed and our quality standard is met. These heads were co-developed with Mitsubishi and are very similar to the 4B11-T.

Audi AAN 5 cylinder head complete for a ‘93 S4. This head was ROUGH at the outset. Besides being covered in peeling black paint and needing all the standard rebuild items, it also had chamber damage from debris, cam journal damage, and a pair of horribly repaired exhaust manifold stud holes. Add in a pocket port and there are a lotta hours in this one 😳. Very happy with the final result; 7A cams, full Supertech valvetrain, fancy seat profiles, and the port work means she’ll be a ripper.

Series of pics showing the recent progress on this Audi AAN head. So many steps involved when you’re chasing the best product you can build.

Refurbished a set of BMW M54 cam trays to go with a new set of Schrick cams in a head I rebuilt awhile back. Should have taken before pics, but picture congealed globs of oil and lots of oil staining. 😂

Another multi caption post to follow yesterday’s. Customer for whom I built a 944 Turbo head a few years back needed the left engine mount arm modified for a Himni Racing T to GT series adapter. The adapter has an o-ring groove that had nowhere to seal against on the factory arm. I turned up a nice chamfered plug on the lathe that was a light press fit into the original oil hole. The plug was a clean way of shrinking the ID to what was required by the adapter.

The original o-ring groove and plug welded up.

Peened weld.

After a few passes on the mill.

Not the simplest part to mount and square up. Took some tomfoolery.

Finished result.

Perfect surface for the adapter’s o-ring to seal against.
