i have a 91 honda accord and its in amazing condition, its been in my family for 18 years and i have redone the interior and i do not plan on selling it anytime soon. yet i want to do some engine work. i am thinking of buying a new engine all together yet i want one that has better performance, torque and over all makes the car able to keep pace with a stock 5 series beamer or somewhere around that powerful in performance. also if you could tag on a price range that will be great
