want to change out my auto to a t-5, i understand i should look for an 88' or better t-5... how can i tell the difference? i also need to know how to identify a v8 t-5 from a v6 t-5. while doing this i would like to upgrade to a 140 mph speedo cluster but i was told the 85' ta is different from all other years...how can i get a 140 mph speedo into my car with a t-5?

 

oh, forgot...anyone know if the car will loose any weight going from auto to manual?

 

Depends what manual you go to -- but the world class T-5 like you're talking only weighs about 75 lbs. Definitely less than a 700R4
