Gord I think he got them from a old mate of his :wink:
He did manage to find the same piston from another Toyota engine that was the same as the 1G engine
Ask him at the christmas party as i'm sure he will tell you

dimis Yes this is true. The supercharged enigne of MR2 MKI has the same pistons.
Quote:4A-GZE
The 4A-GZE (produced in various forms from 1986 through 1995) was a supercharged version. Based on the same block and cylinder head, the 4A-GZE engine was equipped with a Roots type supercharger and therefore the compression ratio was lowered via the use of forged dished pistons. Although fitted with forged pistons they still had the same ports, valve timing and head gasket as the standard 4A-GE engine, although TVIS was omitted as it was not needed in this boosted application. It was used in the supercharged AW11 MR-2 in 1988 and 1989 and overseas in the pre-MY1990 AE92, rated at 145 PS (107 kW; 143 bhp) at 6400 rpm and 190 N·m (140 ft·lbf) at 4400. Later versions (MY1990+ AE92) were equipped with MAP (D-JET) air sensors instead of AFM (L-JET), 8.9:1 compression, and a smaller SC pulley and were rated at 165 PS (121 kW; 163 bhp) and 210 N·m (150 ft·lbf) for the AE92 and 170 PS (125 kW; 168 bhp) and 210 N·m (150 ft·lbf) for AE101 Corolla. These engines are also popular for a turbo conversion, as many parts do not need to be modified to support the extra boost.[9] The 4A-GZE, like the 4A-GE, also comes equipped with a high strength forged crankshaft.
Applications:
AE92 Corolla 1987–1991 (Japan only)
AE101 Corolla 1991–1995 (Japan only)
AW11 MR-2 1986–1989
AE92 Sprinter 1987–1991 (Japan only)
AE101 Sprinter 1991–1995 (Japan only)
