Hey what is the best transmission would be for my 1991 Civic Ex 4 Dr. D16a6
for street racing?

 

Stock

 

ummmm; no. if you are interested in *drag* racing then the Si tranny would be your best option.

 

SO you saying that I should just go with stock? Cause I want to get a new trans, and stage 2 or 3 clutch. My stock trans is now making a grinding noise from 2nd to 3rd.

 

Do you guys think, if I get heat wrap on the intake will it be better like that, I know that I will still suk in hot air cause of the engine, but I was just wondering if putting the heat wrap will protect the intake from getting hot? Any get better performance?

 

The EX tranny is the same as an SI.

 

what year of SI tranny will fit my, 91 4 door ex?

all D16A6 trannies are interchangable. BUT 88-89 won't work with your clutch/flywheel. Get a 90-91. before you change it, try putting in some GM syncromesh fluid to smooth out the shifting.

You are right- I thought about stating that after I initially posted, but I had to leave my house & didn't feel like fixing it

 

From what I've heard the EX and Si trannys are NOT the same. The EX has a 4.0FD to the Si's 4.25 I'll do some math/experimenting and see whats up. I'm using my stock EX tranny, 200k miles and still no grinds.

Edit : If it has a 4.0FD when I'm at 80 mph I shoudl be at 3573rpms...if its the same as an Si I should be at 3797rpms...so when I go to work tomorrow I'll see what happens.

 

to my knowledge, there is no 88-91 " EX " trim model. so what ex tranny are you talking about??
