## ⚡ Stock Numbers (Let's Be Honest, It's Fine)
| Spec | Factory A90 |
|------|------------|
| Engine | 3.0L BMW B58 inline-6 turbo |
| Power | 382 hp |
| Torque | 368 lb-ft |
| 0–60 mph | 3.9s (factory) / ~3.6s (real world) |
| Weight | 3,397 lbs |
| Transmission | ZF 8-speed auto (BMW) |
BMW engine. BMW transmission. BMW infotainment.
Toyota built the body, tuned the suspension, and put their badge on it.
The internet lost its mind. We get it.
But here's the thing — **the B58 is one of the most tunable engines on the planet.**
Toyota accidentally gave you a platform that laughs at horsepower targets.

## 🔧 The Build — Street / Track Hybrid
### Stage 1 — Bolt-Ons (~$3,500 | Still daily-able)
- **JB4 piggyback tune + MHD flash** → 450–470 hp on a stock turbo
- **Catless downpipe + intake** → pulls harder from 3,500 RPM
- **Coilovers** (BC Racing / KW V3) → kills the stock body roll
- **Stiffer front sway bar** → completely transforms turn-in response
### Stage 2 — You're Done Being Reasonable (~$12,000)
- **Pure Turbos Stage 2 upgraded turbo** → 550–600 hp
- Full bolt-on supporting mods: FMIC, injectors, fuel pump
- **BM3 full standalone tune**
- Brembo big brakes if you're tracking it
### Stage 3 — It's Not a Street Car Anymore (~$30,000+)
- Full standalone ECU
- Built transmission + differential
- Pure 800 / Precision 6266 turbo → **800+ hp**
- At this point the B58 has been pushed further than BMW ever planned

## 📊 Numbers Recap
| Stage | HP | Cost (approx) | Track Ready? |
|-------|----|---------------|--------------|
| Stock | 382 | — | Weekends |
| Stage 1 | 460–470 | ~$3,500 | Club days |
| Stage 2 | 550–600 | ~$12,000 | Full track |
| Stage 3 | 800+ | ~$30,000+ | Strip / time attack |

## ⚔️ The Controversy
Half the community says: *"It's a Z4 in a dress. Pass."*
The other half says: *"Who cares what the badge says if it runs 9s?"*
Here's where we land:
The GT-R was built from the ground up to be a weapon.
Every part exists because Nissan engineers obsessed over it.
The Supra A90 was built to be *good enough* — and then the aftermarket turned it into something Nissan engineers would lose sleep over.
Different philosophies. Both valid.
But if you're buying a platform to build on — the Supra is genuinely one of the best choices in the game right now.
The B58 responds to mods the way the 2JZ did in 1998.
That's not an accident. That's Toyota knowing exactly what they were doing.

## 💬 GT-R or Supra — which platform would you build on and why?
Drop it below. We're reading every reply.
> **Next week: 760 horsepower. Supercharged. Hand-built in Michigan.
> The car Ford made to prove America still knows how to do this.
> The Shelby GT500 doesn't ask for your opinion. It just runs.**
