Power by stage
Stock is Honda's US figure. Stage 1 is engine power from Hondata's tunes; Stage 2 to 4 are at the wheels (whp), as US tuners quote them, so they read lower than engine power. US 93 octane equals 98 RON, the best fuel sold in Israel.
Names with an arrow go straight to that part's product page for this car. Names in a dashed outline are other brands that make the part; exact links for them are being added.
Stage 1: Software only
340–365 hpA tune on a standard car adds 33 hp and 39 lb-ft on 91 octane and 47 hp and 72 lb-ft on 93, Hondata says, and 58 hp on a 25% ethanol blend (Hondata). Honda locked the FK8's engine computer, so it has to be jailbroken first: Hondata does 2017–2019 cars with its instant jailbreak, and 2020–2021 cars need its jailbreak module (Hybrid Racing). COBB's Accessport includes an unlock box for 2020–2021 cars (COBB).
Typical cost: Hondata FlashPro $695 at launch, plus $250 for the computer jailbreak.List prices, Sept 2026, before shipping, import tax and fitting.

Reads the ethanol content so the tune can use blends like E40–E50.
Stage 2: Intercooler, intake, downpipe and fuel system
360–400 whpThe stock intercooler heat-soaks quickly, so it's the first part. On Hondata's dyno for DSport, Full-Race's intercooler kept intake air around 72°F where the stock one rose from 77°F to 117°F, and gained 8.64 whp (Full-Race). The engine has direct injection only, so more power needs more fuel: Full-Race says a car with an intercooler, downpipe, front pipe and cat-back went from 360 to 400 whp on the stock turbo with Hondata's fuel system (Full-Race).

|---|---|---|---|---|
| Full-Race intercooler | — | +8.64 whp | — | Hondata's test for DSport |
| Injen intercooler | — | up to +27 hp | +23 lb-ft | Works with the stock calibration |

Stage 3: Upgraded turbo
450–550 whpStage 3 replaces the turbo with a bigger one that bolts into place. 27WON's Kuro is sold for up to 500 whp on the stock fuel system (27WON), Full-Race's kit is quoted at roughly 400 hp on 91 octane and 500+ on race fuel or E85 (Full-Race), and PRL calls its P700 600+ horsepower capable with a custom calibration (PRL). PRL's P600 test car, with its bolt-ons, Hondata's fuel system and a built engine, ran a 10.91-second quarter mile (PRL).
Typical cost: turbos $2,200–$4,800 (27WON, PRL, Full-Race); Exedy Stage 2 clutch £638.List prices, Sept 2026, before shipping, import tax and fitting.

Stage 4: Big turbo and built engine

One FK8 for sale with a Rampage G30-660 kit, a built engine with a sleeved block and a full fuel system is listed at 485 whp on 93 octane and well over 600 whp on ethanol (Built for Backroads). 1to1 Tuning sells a built K20C1 rated for 650 hp and up (1to1 Tuning).
