My combo is pretty mild. I have a stock motor with a TE-44 turbo and 50's. I am capable of running high to mid 11's (mid 11's if I really push it). My question is...I am getting my tranny rebuilt by Janis Transmissions and I was told the price of the total rebuild will be around a grand if I don't use the two billet parts (forward drum and input shaft). If I do it will be around $2200. Or it will be $1500 if I use just the billet forward drum. Now with a car like mine which is full weight and everything...not planning on going faster than I am now...should I do these two mods? Sounds like these two items are only neccessary if your car is a full race car/weekend racer. My car is mostly street driven with OCCASSIONAL trips to the track. Should I use any of these two items in my rebuild??? Those two parts alone are EXPENSIVE!
