Very proud of these. Six months ago I owned only the 1990 Si. I was looking for a parts car for the 1990 when I stumbled on the 1991 Si. Now the 1990 is the parts car. 220K on the 1991 and 190K on the 1990. The Eng bay pic is from the 1991. This is how I bought this car. The 1990 is nearly as clean but not quite. Valve covers are extras I just finished. They are going on both cars. The black ones coming off are going to get the same red wrinkle finish and going on ebay.
