simply because its not an STI.What you can do is sell it and get a Honda type r or s2000....or even a 1998-2000 civic v tec and drop in a b20z motor to get 150+ kw
5W30
Probably 10-40W Probably is not an Answer!!! I know the 6 cylinder is 5w20 or 5w30.
5w 20
it needs 10w-40
That would depend on the type of car. Most likely not.
