1993 Toyota Supra (MK3 Turbo) — Should You Buy One?

Typical asking price: $12,000–$28,000. There are 3 high-severity known issues you need to know before handing over a check.

Kestrel Take

The overlooked Supra — the MK3 lives in the MK4's shadow, which keeps it (relatively) affordable. The 7M-GTE is strong except for one infamous flaw: the factory head-gasket torque spec was too low, so a re-torqued or upgraded gasket is essential. Rust and modification history do the rest.

Known Issues for the 1993 Toyota Supra (MK3 Turbo)

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

7M-GTE head gasket failure (factory torque spec)High — wallet impact

Toyota under-torqued the head bolts from the factory, causing chronic head-gasket failures. The fix is ARP studs and a re-torque; verify it was done or budget for it. An un-addressed 7M is living on borrowed time.

Repair cost range: $1,000-$2,500
