Hi.

I have a civic ef 1.3l engine and was wondering if there are any mods i can do?

(I dont want to replace the engine)

 

well you came to the right place

heres two questions for you
first

what does your civic have that you feel needs to be updated?

and second
what is a problem that your having right now that you feel like fixing?

for example
when i first got my civic i noticed that on the interstate going 75mph when going up a hill
the car would slow down to about 70-68 ish mph
my fix for this was going from a automatic to a 5 speed
after that was done the car would stay at 75 mph even while climing those long hills

remember that a mod is only a mod if it make the car better than it was in the first place

 

My honda is a manual 5 speed looking for some extra hp i can gain or some low end torque maybe some mods like changing the exhaust manifold or something like that
