GCG TO4Z Turbo Kit w/ Wastegate Pipe & Exhaust Manifold - FC3S RX-7 13B-T

This is a GCG TO4Z (Garrett-based) turbo kit including a wastegate pipe and exhaust manifold, built by GCG/HKS for the late-model Mazda RX-7 FC3S with the 13B-T rotary engine. The seller states it was previously used without issue: the turbine wheel spins smoothly with no shaft play. The exhaust manifold flange has a crack, though it does not extend to the outer edge and currently shows no exhaust leak. The catalytic converter is a one-off unit based on the OEM part; its internal substrate has collapsed and the seller recommends converting it to a straight pipe. General wear includes scratches, rust, weld marks, and deterioration of the heat shield. V-band clamps are not included and must be sourced separately. Only the parts shown in the listing photos are included; any additional hardware, bolts, nuts, or sockets are not provided, and the seller cannot guarantee which incidental parts may be missing.

Seller self-grades this D, needing repair: the exhaust manifold flange is cracked (not through to the outside) and the catalytic converter's internal substrate has collapsed, plus general scratches, rust, weld marks, and heat shield wear.
