Engines going to get complete rebuild with new mains, arp rod bolts, jap type r pistons, new oem oil and waterpump and belt. Type r head and valves/springs with b18c4 cams, oem head gasket. Should be about 11.25:1 cr. Not a complete wrap up there who knows i change my mind alot. Still havnt got any bits for the gearbox which will need rebuilding/i want to rebuild.
