Hello. I have a 1984 vanagon and will be installing a 1998 subaru 2.2 engine in it. I chose the 2.2 because I have a 1997 Legacy and a 1998 Impeza as parts vehicles. Both engine are in good running condition but I plan to use the !998 Impeza engine because it has lower miles. I plan to rebuild the engine completely and am looking for any ideas for performance improvements. I am aware that this single port engine was only used for two years and am finding that some parts such as pistons are difficult to find. Any ideas would be greatly appreciated. Thanks
