#6 Spec A2,B,C camshafts / valve springs / adjustable cam pulleys / 2.2L stroker kit (Turbo with rods)
or
TODA 2.2L turbo crate engine.
*NB: Turbo shouldnt be too small. This will cause excessive thermal stress on engine.
Bolt-on turbo to std engine, use 450hp turbo minimum.
Eg: HKS 3037S
Std engine will produce 190rwkw @ 6psi with correct set-up
NB: Some popular intakes are not as good as they appear. (Chose carefully)
High compression & low compression forged pistons are available in both 2.0L, 2.2L.
Forged NiCr connecting rods are also available for both 2.0L & 2.2L
Rear diff can present problems after fitting heavy duty clutch.
Hyper single clutches not recommended for daily drivers
Much work needs to be done to improve handling of vehicle.
High power outputs require stronger engine mounts.

By request,
Bang for your buck DC5R
As with DC2, The DC5 is pretty fussy when it comes to mods that actually work
On the race track
The following parts are must haves
Oil cooler / low temp thermo fan switch
If you cant afford a good aftermarket radiator, at least fit a low temp thermostat.
Both are better
. Suspension & brakes also need to be addressed.
These aught to be addressed before you chase any extra HP.
As for getting more power, Hondas are pretty fussy
The actual parts combination is everything
It must be put together exactly right
I cant stress enough how important this is.
Once its put together right, it can be tuned
This also should be spot on
The three work together, if 1 side has a weakness, power suffers
Examples: Your pipe dream combination isnt right
Power suffers
Your mechanic doesnt really know what hes doing
Power suffers
Even with perfect combination & assembly, with crap tuning
Power suffers...
NB: When fitting a heavy duty clutch to a DC5R, the front and rear engine mounts should be attended to.
That is fill them with sikaflex or use Mugen inserts / mounts.
This will avoid the inevitable knocking on the floor under the driver of the exhaust system.
Minimum budget Just a bit quicker
#1 Intake - Never use a SRI of any brand CAI only (Eg: INJEN / AEM / GruppeM)
#2 Header + S2000 cat + cat-back system (60mm minimum)
Power output: 116 ~118kw @ wheels (Dyno dynamics- shootout)
Low budget Sleeper (Quiet & quick)
#1 Lightweight flywheel
#2 Heavy-duty clutch
#3 Lower final drive
#4 Modified stock airbox (Aka Hondata)
#5 Header + cat + JDM DC5R or Mugen cat back
#6 Hondata K100
Power output: 120 ~122kw @ wheels (Dyno dynamics- shootout)
Low budget never going to get an ECU

#4 Intake CAI's deliver superior results.
#5 Header + S2000 cat + cat-back system
NB: DC5R cat back can be used on base model with small mod to rear or base model cat.
Further modifying the airbox Hondata style also adds a little power
For those who aren't sure, automatic models do not have flywheels or clutches
Regarding modifying your car.
If you cant afford to do it the right way, avoid the temptation to do something right now & save up until you can afford to get the right parts.
Obviously I recommend using only TODA products where they exist for the application.
Products from other manufacturers can be substituted with varying levels of effectiveness.
Ok
as before
