Plenty of INFERNO engines in circulation are Gen 1, and they still work. What they lack is the Gen 2 electronics and the features that came with them, which is where an upgrade kit earns its place: you keep the engine you own and move it forward.
This is the V3 version, meaning the AK gearbox rather than the V2 M4 shell. Gearbox format decides the kit, so the V3 parts are not interchangeable with a V2 conversion even though the engine family is the same.
Worth being clear about what an upgrade is and is not. It moves your existing INFERNO onto the newer specification; it does not turn a Gen 1 into a brand new engine, and anything already worn out stays worn out.

Good to know before you buy
Check your gearbox version before anything else. V2 is the M4 shell and V3 is the AK, and ordering the wrong one is the single most common mistake on a kit like this.
Treat it as a specification change, not a service. If your Gen 1 has a tired solenoid or nozzle, budget for those alongside the kit rather than expecting it to cure them.
Frequently asked questions
What does the kit actually change?
It takes a Gen 1 INFERNO onto the Gen 2 specification. Tell us your current setup and we will confirm exactly what you end up with.
Will it fit a V2 M4 gearbox?
No. This is the V3 AK kit; the V2 route is a different kit.
Do I need to send the engine anywhere?
It is a parts kit for fitting. If you would rather not do it yourself, our HPA tech service handles installation and tuning.
Is it worth it over a new Gen 2 engine?
Usually yes if your Gen 1 is sound, because you are paying for the difference rather than the whole engine. If yours is worn throughout, a new engine is the better buy.
