Rocketeer Just Put 300 HP of Jaguar V6 in the “Most Hated” MX-5 — And the NC Finally Has a Job

Rocketeer’s Goodwood NC MX-5 packs a ~300-hp Jaguar V6 without cutting the bulkhead — proof the NC wasn’t the problem.

Rocketeer Just Put 300 HP of Jaguar V6 in the “Most Hated” MX-5 — And the NC Finally Has a Job

Purists blamed the chassis. The boring engine was the real crime. AutoSnipes is here for the donors — and the sellers who finally have a story.

The pitch

~300 hp. Jaguar AJ30 3.0 V6. No bulkhead cut. £25,000 + VAT (~$33k) turnkey on top of a donor NC. Goodwood Revival debut. From the outside: gold wheels, slightly louder tips, OEM+ stealth so complete that most parking lots won’t clock it.

Rocketeer Cars — the British shop that already built a reputation stuffing characterful V6s into NA and NB MX-5s — just finished the generation everyone loves to dunk on. The NC. Too heavy. Too soft. Too far from the Elan fantasy. Evo, HotCars, and PistonHeads all ran the same thesis this week: the Mk3 wasn’t the problem. The four-cylinder that never asked enough of the chassis was.

Why the “worst” MX-5 was the right canvas

Rocketeer didn’t pick the NC because it was fashionable. They picked it because the platform could absorb what the featherweight generations couldn’t.

  • AJ30 V6 (Jaguar / Ford Duratec family) fettled to roughly 300 hp / 265 lb-ft — PistonHeads cites 304 hp / 300 bhp in Rocketeer’s tune
  • 18 months of packaging work so the heavier V6 keeps overall weight and weight distribution in the stock NC’s neighborhood
  • Subframe stays Mazda. Bulkhead stays Mazda. The surgery went into the engine — bespoke cylinder head, carbon-fiber inlet plenum, revised throttle body, new clutch and flywheel, freer exhaust — so the car didn’t have to be cut open to accept a personality transplant
  • OEM+ stealth on the turnkey RF shown at launch: two tells, not a widebody cosplay

That’s the adult argument. Earlier generations demanded structural compromise (or accepted a weight penalty that fought the car’s point). The NC’s extra real estate — the same trait that made forums cruel — is exactly what let Rocketeer seat a proper V6 without turning the roadster into a science project.

Mazda’s philosophy still holds: the MX-5 is a momentum car, not a torque comic. Rocketeer isn’t arguing with that. They’re arguing that if you’re going to add power, preserve the analog balance or don’t bother. Feel over figures. Character over mismatched track-rat energy.

Turnkey money vs “it’s just an old Miata”

| Spec | Number | What it means |
| --- | --- | --- |
| Turnkey NC conversion | £25k + VAT (~£30k UK / ~$33k + tax context for US buyers) | Heart transplant, stock-looking car |
| Restomod path | More ££ | Visual + chassis work beyond the engine |
| Shop track record | ~30 completed cars / ~180 kits worldwide (NA/NB programs) | Not a one-off press car |
| New MX-5 context | New 2.0 was already £35k+ before discontinuation math | The “expensive used Miata” objection needs a reality check |

Yes — that’s a lot of money for a third-gen MX-5. No — “just buy a new one” stopped being a clean rebuttal when new roadster money crossed into serious territory and the ND’s replacement path got weirder. You’re buying a high-revving V6 character piece that still looks like something a normal person parked at coffee. Stealth is the product. The power is the excuse.

Rocketeer’s NA/NB customers can already chase a 375 hp / 9,000-rpm version of the same V6 family. The NC launches at 300. Read that as a floor, not a ceiling — and don’t invent future prices AutoSnipes hasn’t seen hammer.

The AutoSnipes angle: NC donors just got a job

Forum hate suppressed NC values for years. That created a junkyard-to-driveway inventory of soft-top and RF cars that are:

  • Cheaper to source than clean NAs/NBs in many markets
  • More available as honest drivers with known miles
  • Suddenly relevant as conversion platforms, not just “the heavy one”

If you own a clean NC — sorted compression, no crusty sills, manuals that shift — you are no longer stuck explaining why you didn’t buy an NB. You have a platform story. If you’re shopping donors, the rubric flips: buy the best chassis and interior you can, because the engine bay is about to become someone else’s religion.

Seller rule: do not list your bone-stock NC at “Rocketeer money.” List it as a sorted donor or an honest driver with comps in the stock band. Conversion headlines are attention. They are not your ask’s justification unless the V6 is already in the car with invoices.

Buyer rule: a Rocketeer turnkey is a shop product with a published package price. A Facebook “V6 swapped NC” with no bulkhead photos, no weight-distribution claims, and a “trust me bro” wiring harness is a different animal. Pay for engineering receipts, not for the word “Jaguar” in a caption.

What private sellers should steal

  1. Lead with the platform truth — NC size/weight as feature for packaging, not apology copy
  2. Itemize the work — head, plenum, clutch, exhaust, “no bulkhead cut” is a checklist, not a vibe
  3. Separate turnkey from restomod — stock body + V6 is one product; gold-wheel hero car is another
  4. Disclose donor condition — miles, rust belt history, soft-top vs RF, prior accidents
  5. Don’t invent hammers — use the £25k+VAT package number; leave fantasy resale multiples off the page

Goodwood was the debut — the market is the hangover

The car’s public debut at Goodwood Revival (Sep 20–22, 2026) was the press moment. The useful aftermath is quieter: NC prices, kit vs turnkey demand, and whether private-party sellers start describing their soft-tops as “Rocketeer-ready” without a single torque wrench having entered the chat.

AutoSnipes is built for that hangover. Surface the comps that match your NC — stock driver, clean donor, or actual converted car with a file — and stop letting one Goodwood paddock photo reprice every Mk3 on Marketplace.

What to do with this

If you’re shopping MX-5s: open AutoSnipes /cars, filter NC vs NA/NB like a grown-up, and decide whether you’re buying a momentum toy, a donor, or a finished conversion. Those are three listings pretending to be one search result.

If you’re selling a clean NC: list with compression numbers, underbody photos, and an honest “stock driver / conversion candidate” frame. Steal Rocketeer’s file discipline. Leave their sticker price off your ask unless the engine is theirs.

If you already drive an OEM+ stealth missile that makes strangers lean in at lights: Street Visibility puts a QR on the car so curiosity becomes a lead instead of a napkin under the wiper.

AutoSnipes CTA

The NC’s reputation was a tax. Rocketeer just argued the chassis deserved a better engine all along. Your job is simpler: price the car you have, not the press car you saw at Goodwood.

Browse Miatas and MX-5s on /cars. Selling? /list with the photos and invoices that survive scrutiny. Already driving something that stops the right people? /street-visibility.

The NC isn’t the problem. Boring engines are. Know which market your roadster is in before you publish.
