2.4 DOHC Conversion

Click images to see more pictures from each day

The Original Plan: Remove engine,line-bore the block, mill the deck flat, bore cylinders straight, and balance it. Shot-peen the stock connecting rods and replace the stock 8.7:1 pistons with forged 9:1 pistons. Get intake and exhaust valves high-temp coated and get head work done. Replace stock wiring harness with one from a 1993 turbo Mitsubishi Eclipse. Install a 1993 turbo AWD 5-speed ECU. Bolt on a turbo DOHC cylinder head and connect everything back up. Basically copying a turbo Eclipse configuration using the stock 2.4 Hyundai block. Including the knock sensor, DIS ignition, and all the emissions equipment.

Unfortunately, this project was not as simple as originally thought. Plus I have upgraded lots more than originally planned. Many of the upgrades were not required to get the car running.
