To all Cison V8 Engine enthusiasts:
First and foremost, we want to offer our sincere apologies for the long period of stock shortages. Over the past months, we’ve received countless inquiries and messages of anticipation—each one a reminder of the trust you’ve placed in us. This is why we’ve taken extra care to refine and upgrade the product, leaving no detail unpolished. Now, we’re thrilled to share: The all-new, upgraded Cison V8 will officially ship in mid-to-late July!
1.New sealing ring for cylinder head
The latest V8 models feature an additional seal ring on the cylinder head, boosting sealing performance significantly. This small but critical improvement effectively prevents oil leakage and seepage, reducing long-term maintenance needs while enhancing engine stability and efficiency
2.Gold-Coated Pistons: Unmatched Durability
You Can See Our new gold pistons boast a special surface coating, delivering a dramatic leap in scratch and wear resistance. Even under violent scraping with hard objects, the surface remains unmarked—unlike the older silver pistons, which show clear scratches after similar tests (damage that can compromise performance over time). This coating ensures the pistons stay intact even under high-intensity operation, extending their lifespan significantly.
3.Upgraded distributor with variable ignition angle
The distributor is now equipped with a variable ignition timing function, which can adjust the ignition angle. This optimizes fuel combustion, resulting in smoother power delivery, quicker response and stronger dynamic performance.
We know the wait has been long, but we’re confident this upgraded Cison V8 will exceed your expectations. The all-new Cison V8 arrives in mid-to-late July—thank you for your understanding and support. We can’t wait to deliver it to you!

Am I the only one wondering why buyers of the very first batch of the CISON V8 are not getting the upgrades as spare parts for free or at least for a couple of bugs? I remember in the beginning of 2025 Jan-March ALL Toyan FS V800G customers received an upgrade Kit with seals, screws, piston rods for free. And they didn’t even pay as much in the first place, or in other words only 2/3 of the mony. We invested in a totally unknown brand and product, knowing nothing about the relyability, endurance and buildquality… On the other hand as everbody knows with Toyan engines a lot can go sideways. In the article above I read lines like: “prevents oil leakage and seepage”, “reducing long-term maintenance needs while enhancing engine stability and efficiency”, “prevents potential damage that can compromise performance”. That makes me feel like I am going to blow the thing up by only hitting the gas, shredding the four figures price tag.
may be the new cison improvements will finally get my CISON V8 running – the longest run was 30 Sek. in idle ( low RPM ) as soon as the trottle is touched the engine quits…
