316 stainless steel construction eliminates the most difficult fabrication steps involved in turbocharging a pit bike engine. Each header and downpipe is precision jig-welded for consistent fitment and long-term durability.
No welding and no engine-case drilling required.
Aluminum intake manifold / 26mm carb adapter with O-ring seal
Turbo oil supply kit: banjo fittings + high-pressure oil line
Turbo oil return system: flange, hose, clamps, and modified valve cover
316 stainless engine-to-turbo header
Universal 316 stainless stubby downpipe (no muffler)
Complete bolt-on hardware pack
Full 316 stainless post-turbo exhaust (downpipe to muffler) for select models (Apollo RFZ 125, etc.)
O₂ sensor bung for easy tuning with a wideband AFR gauge
This kit fully plumbs the turbocharger to your engine—oil feed, oil return, intake manifold, header, and all turbo connections—eliminating the most challenging fabrication work so you can focus on installation and tuning.
Engine setups vary widely (compression ratio, ignition timing, carburetion, altitude, temperature, fuel, engine condition), so final tuning and safe operation are the responsibility of the installer.
For off-road use only. Improper tuning can cause engine damage.
No liability is expressed or implied.
A properly tuned VZ21 system on a stock 125cc engine with a 26mm carb typically produces 3–5 psi of boost, offering a noticeable increase in torque and mid-range performance.
Results vary with tuning and operating conditions.
Made to order — 3–4 week lead time
Turbocharger and carburetor not included
VZ21 turbocharger requires a minor modification (available separately)
