hi,

i just recently bought a 1987 Rx7 and i dont have that much knowledge on rotaries... i was wondering which model 13b motor i have? i know theres alot of different type 13b motors out there and i want to know which one of them i have because i am planning to do a rebuild because i purchased the car with a blown motor. i know it may sound stupid to buy a car with a blown motor, but i am really interested in rx7's and how to rebuild there engines. i can really use some help. well thanks for reading!!! ^_^

Thanks,

If the car is stock and NA, you have a 13B 6 port. If the car is turbo, you will have a 13B 4 port, commonly referred to as a "13BT".
