The 175hp RENAULT 21 Turbo, built from 1987 to 1990, uses the 2.0 turbo J7R 752. This page carries a single active reference.
It is the WOSSNER forged piston set for the J7R 752, offered in two bores: 88mm with an 8:1 compression ratio, or 88.5mm with 8.1:1, a low ratio suited to forced induction.
No con rod, bearing, gasket or head part is linked to this engine so far: building the J7R here starts with the pistons.
