Adding horsepower
 

I have a 99 v4 accord


I would love ANY advices or suggestions on how to do easy modifications or
tuning for the engine.

I just took some interest in the modification stuff and i would love some
easy to do things to add some horsepower and performance for my accord.

please contact to minyoung0115@comcast.net or please simply reply

thank you.

No, you don't! perhaps you have an I4 Accord, but they never put a V4 in
one. Saab had a V4 in the 70's, but it is a very unusual constellation
for a 4-banger.

By "easy to do" I assume you mean bolt-ons, nothing that involves engine
work or forced induction.

You could install a CAI (cold air intake) and a free flow exhaust. On
some cars like the base RSX where the stock air intake is severily
restricted there are gains of 13-20hp. However on the Accord you won't
see nearly as much, probably less than 10hp. Short ram intakes are an
alternative to CAIs, but they're a waste of money IMO, because they take
the hot air from inside the engine bay rather than cold air from the
outside.

The only way you can get real power increses is by either doing forced
induction (turbo or supercharged) or engine modifications, but either
one is fairly expensive. If you don't have that kind of money, it may be
better to focus on the handling of the car and the breaks.

The Accord is far from a sports car, and its handling is pretty poor on
the stock tires and suspension. My dad's 02 Accord I4 sedan handles like
a boat compared to my 01 Prelude SE. That could easily be improved by
getting good tires. No need to change the stock rims (unless they're the
steel ones), because most cheap aftermarket rims are heavier than stock,
and the more unsprung weight that you have the slower your car will be.

The suspension is another weak point. There are too many options in this
respect to list here, but a set of aftermarket shocks is not
prohibitively expensive. If you do change the tires and the shocks be
warned that the ride will become less comfortable than it is right now.

A good set of break pads and rotors will also help. But do keep in mind
that the Accord is a heavy car (even the coupe is fairly heavy), so
unless you will do extensive mods to it, it will never compare to a real
sports car. Even my Prelude is heavy, a Civic or an Integra (or RSX) are
much better suited for mods.

If I missed anything, I'm sure others will come up with other ideas.

Not quite... As long as you're comparing Al, Fe and even Mg wheels,
and not Pb to Mg, there will be no discernable difference in velocity
or acceleration. A reduction in unsprung weight will, however, be
noticed in both ride and handling.

Wrong, I already found 8 cheap / f-o-c ways to increase pwr / torque,
below is 1.

Honda fits only short ( 4 into 1 ), cheap & heavy cast iron exhaust
*manifold for its engines <2.2 litre, result is lower though adequate
torque @ low rpm ( as during buyers' test drives ), but very low ( <½ as
much ) torque & mpg @ high ( >3000 ) rpm. My 4-2-1 * uses
aluminised mild steel : 13 kg < the original * on my F20A engine.
In 6-02 I saw a new Civic vtec 1.6 litre engine with very short * : a waste
of vtec ( no way is torque / mpg esp @ high rpm maximised ).
Many car makers ( incl Nissan in Sunny 130Y, Hyundai in Sonata 2.4
, Proton in Waja 1.8 ) save on *, because 99.9% buyers do not test drive
on highways, or know / experienced the difference between short &
long *.
