Head Drilling

Unfortunately, the ZC32S head doesn’t have all exhaust manifold holes drilled and tapped – unlike the ZC31S. I only heard about this reading the documentation from the shop in NSW (One Stop Mechanical) that originally fit the turbo to the ZC32S I purchased the kit off. I later confirmed this was the case when I removed my extractors from my current setup.

I did my best to mark out holes but wasn’t entirely happy with how I had measured and drilled.

With how tight the holes on the HKS manifold are to the M10 studs, you don’t get much allowance for error. With this in mind, I decided to only tap the 4 extra holes to M8 (instead of M10) to give myself a bit more room to play with. This worked out great.

My only remaining concern is the depth of one of my drillings. It’s 1-2mm deeper than the factory drillings. Looking at the casting, I think we are fine. Famous last words?

My Suzuki Swift Sport ZC32s

Purchased in late 2020 with 67,000 kms this car was to be my new daily.

I attended a track day at MTA Wodonga (Logic Center) one week after purchase to get an understanding of the car in factory trim. This ZC32S was to build on learnings from our previous two swifts and become a street registered “track” car. You can read about my previous cars here.

In 2025 I picked up a HKS turbo kit suit ZC31S that had previously been fitted to a ZC32S. A large driver for this blog was the documentation of this phase of the build.
