Description
01
What it is
The K24z mounting and exhaust system from Bostig allows flexibility, functionality, and protection. Integrated full protection skidplating for engine and transmission is just the start. The ability to install the K24z engines into 83-91 VW Vanagons with selectable engine decklid rise is both game changing and practical.
The manual
The full K24Z build reference is free and public at docs.bostig.com/k24z, available before you spend a dime. It's a living document and says so at the top, growing as the line grows.
02
What it has
The armored system includes all of the skidplating, mounting, brackets, and hardware. The downpipe and crosspipe are added at checkout for $400. Muffler and muffler isolators are purchased off the shelf.
Through extensive testing, we've selected an optional stainless resonator that makes the K24z exhaust as quiet as possible without a noticeable hit on performance. The optional resonator is not compatible with some trailer hitches, so consult with us first.
The rear support bracketry is now optional. Unless you are doing serious or competitive rock crawling (in which case you might re-consider the Vanagon as a platform), it is overkill, and just adds weight.
I drove the newly-installed K24z back from Boston to Saint Louis, Missouri. That was a 1200 mile, 20-hour first-drive, and it handled it like a champ. Driving the Vanagon with a K24z makes accelerating onto the highway just like driving a modern car. No more worries about getting up to speed and plenty of oomph to get up the long steep hills without a strain.

What is the cost to complete the install if I buy the armored system?
DIYing is *the* cheapest way to get into a K24z. The additional finished cost with a K24z2/3 can start as low as $6,700. The first Bostig K24z install as it stands now was actually done for $6500 (yes, everything, including the engine).
Are you going to be offering a full kit?
Not this season, but perhaps next. We will be offering installs however, email us or call if you're interested. Expect eventual pricing for the full kits to be in the $9500 range. Turnkeys in the $16k range. Most of the parts are simply bought from a list, and you're paying us engineering rates to order, pack, and ship them (twice). This is why we encourage DIY!
Is the K24z cali legal?
Not yet, but it's getting closer! Because of the choice of engine and our exhaust design, it is possible to run *both* CA legal catalytic converters and not delete any emissions system components. This means it is possible to get a BAR ref to allow it (there's never a guarantee). If we have enough interest, pursuing a CARB EO (which we have experience doing) is also an option (which would provide the guarantee). But there is currently no plan for this.
Will the angle changes of the engine and transmission affect syncro driveline angles?
Yes. As with any driveshaft, the angles should match to prevent torsional vibrations and shorten joint life. This can be accomplished with both the front diff angle, and the transmission. The Bostig mounting system can also allow the front transmission mount to be relocated from the body to the front plate, and from hanging, to supported from underneath which lends to further adjustability.
Is there an upgrade path for Bostig Zetec customers to the Honda?
Yes, however it isn't a hardware compatibility that allows it. We will be offering a trade in program. Since the most expensive custom parts for the Zetec are either non-wearable or serviceable, we'll offer refurbished Zetec kits to customers looking to get into a Zetec for less money, that can offset the cost of the Honda for existing customers. No other vendor entertains any such idea.
What is the ground clearance?
On the shop syncro with 27.9" tires, it's 7.5" with no decklid lift, to 11.5" with a full lift. And that's at the skidplate, which can be hit... *not* at an oilpan.
