ok just did a compression check on my 87 turbo and the compressions were 1-2-3-6 were around 120 and 4-5 were less than 90. spark plugs 1-3-4-5-6 were all red in color and 2 had oil deposits on it. i just changed the hg in january and have only driven the car maybe a month max. so i think it is time for a rebuild or i might even put my n/a block from my wrecked supra into my 87 and just do a na-t. wut do u guys think? its either that or sell the thing and get another car, which i will be doing maybe a 4dr luxury sedan, and just have the supra as a project car.
