I did the same thing, but ended up spending too much. One thing after another i wanted to replace after having the motor out. Ive got over 11k invested but i did buy everything new. My car is for sale now because im getting married and need to pay off my debts. CC are about 4k. Depending on the condition of your car you could swap all together and sell rolling shell for 1k. take a look,
