Hi,i have a civic 97 sedan with a d15z4 non vtec engine and i'm interested to change my FD from 4.25 to 4.9.Is it good for a 400m?Note that my engine is stock.Light tuned like sport air filter,exhaust and iridium spark plugs.

 

20" slicks will give same effect and help with traction off the line.

 

Yes its a great start. Before I even put an intake on my car I put a 4.7 FD in it. Playing around with the trans I was able to go from a stock 17.7 to a 16.04. Only changes to the engine were a VTEC head swap.

 

i'll definitely go for it.Its the Mfactory 4.9.My actual FD is 4.25.I think it should be good for the 400m drag.

 

im running the 4.9 gear x final drive and its deff. well worth the money!
