SW20
Toyota MR2 SW20 import check
SW20 is the factory model code for the Toyota MR2 SW20, built for the Japanese market from 1989 to 1999. Every genuine car has a chassis (frame) number that starts with its code, such as SW20-. That number is the one thing that links its Japanese history to its UK records.

Reading the SW20 chassis code
- Every Japanese-market second-generation MR2 is SW20, turbo or not.
Have a chassis number? The chassis decoder reads it for you.
Is it a genuine SW20?
GT and GT-S are the turbo cars, but every Japanese-market SW20 shares the code, so check for the 3S-GTE engine and intercooler. UK-market MR2s have a 17-character VIN starting JT.
Known problems to check on an SW20
- Its tricky handling at the limit means many have had accidents: check for chassis repairs
- Rust in the rear arches, sills and the front luggage floor
- Turbo cars: blue smoke, charge-pipe leaks and turbo wear
- T-bar roof leaks
These are common issues for the model, not facts about any particular car. Ask the seller about each one.
Before you buy
- Look for water in the spare wheel well and under the carpets (T-bar leaks)
- Check the gearbox for crunchy second and third gears
The SW20 on a Japanese auction sheet
- The sheet names the car MR2. GT and GT-S are the turbo grades; G and G-Limited are not.
Most imports were bought at a Japanese auction, and the inspector’s sheet records the grade, mileage and every mark on the body. Ask the seller for it, then run it through our auction sheet translator to read it in English and check the chassis number and mileage against the UK record.
Recalls in Japan for the SW20
Japan publishes every recall with the chassis numbers it covers. Run a recall check with the car’s chassis number to see whether any apply to it.

Kilometres, miles and the first UK MOT
An SW20 sold new in Japan has a speedometer in kilometres. When it is imported, the speedometer is either converted to miles or left in km, and the first UK MOT should record whichever the dial shows. Mistakes here are common, and they’re where mileage problems hide.
We put the Japanese auction mileage and every UK MOT reading on one timeline and check the crossing: whether the readings agree after converting, whether the km figure was written down as miles, and whether the first UK reading is lower than the car had already done in Japan. See an illustrative example.
Questions
What is the chassis code for the Toyota MR2 SW20?
SW20. A Japanese-market Toyota MR2 SW20 has a frame number that starts with SW20, then a hyphen and a serial number. You’ll find it on the V5C and on a plate in the engine bay.
Which years was the SW20 built?
From 1989 to 1999, with the 3S-GTE (1998 cc turbo petrol) or 3S-GE (1998 cc naturally aspirated petrol) engines and Mid-engine RWD layout.
What should I check when buying an SW20?
Its tricky handling at the limit means many have had accidents: check for chassis repairs. Rust in the rear arches, sills and the front luggage floor. Turbo cars: blue smoke, charge-pipe leaks and turbo wear. T-bar roof leaks. Look for water in the spare wheel well and under the carpets (T-bar leaks). Check the gearbox for crunchy second and third gears. Also check that the Japanese auction mileage lines up with the first UK MOT, because km and miles are easily mixed up.
