From Stock to Monster: How to Build a 500hp Supra

Few cars capture the heart of JDM fans like the Toyota Supra. Whether it’s the legendary MK4 (A80) made famous by Fast & Furious or the sleek new MK5 (A90), the Supra is a platform begging for power upgrades.

But how do you take a stock Supra and turn it into a 500 horsepower street beast without blowing it up in the process?

Here’s the roadmap to building a monster while keeping it reliable — and ridiculously fun.

Step 1: Start With the Right Base

While both the MK4 and MK5 can hit 500hp, the 2JZ-GTE (MK4) is an absolute tuning legend thanks to its iron block and massive aftermarket support. The MK5’s B58 engine is no slouch either, delivering modern efficiency and tech. Pick your platform based on budget, style, and parts availability.

Step 2: Boost Is Life — Turbo Upgrades

MK4 2JZ-GTE: Upgrade the stock twins to a single turbo kit. Popular choices include Garrett GTX or Precision turbos sized around 6266 for a perfect street/track balance.

MK5 B58: Hybrid turbos or full big-turbo kits can push serious power with minimal lag.

💡 Fun fact: The stock 2JZ bottom end can handle 700+ hp if tuned correctly — making 500hp feel like a “safe” number.

Step 3: Fuel and Air — Feed the Beast

High-flow fuel injectors (1000cc+ for E85 or 600–800cc for pump gas)

Upgraded fuel pump (Walbro 450 or equivalent)

Front-mount intercooler to keep intake temps low

Running E85 fuel can unlock more power with less knock risk, but you’ll need the right injectors and tuning.

Step 4: ECU Tuning — The Brain Behind the Brawn

A standalone ECU like AEM Infinity (MK4) or an advanced ECU flash tune (MK5) ensures your upgrades work together. This is where a good tuner earns their paycheck — safe AFRs, boost control, and timing adjustments are the key to reliable power.

Step 5: Support Mods — Don’t Skip These

Performance clutch or upgraded automatic transmission.

Bigger brakes (Brembo, StopTech) to handle the extra speed.

Suspension upgrades for better traction and cornering.

Sticky tires — because 500hp is useless if you can’t put it to the ground.
