the above enigne in his ZX is a CA18DE so if you get a CA18DET from an S13 for parts.. drop the internals in or buy forged items for the S13.. use the exhaust manifold and turbo would need a custom downpipe and intercooler... and you can use the ECU IIRC to control it or an apexi power FC
youll need the FWD block Gbox and inlet manifold as there a different way round lke the SR20
