We’ll take a look at which elements want upgrading – and which of them don’t – to present you a greater concept of the place it is best to spend your cash, and what your subsequent improve needs to be.

The Honda Civic Kind R has lengthy been the go-to sizzling hatch for eager drivers, providing an intoxicating mix of rev-hungry, naturally-aspirated VTEC energy combined with a fantastically playful chassis that rewards ability behind the wheel. The FN2 is an ideal instance of this, however like all mainstream manufacturing vehicles it does have its restrictions and limitations.

Fortunately, there’s an unlimited tuning scene and a military of specialists to assist Civic Kind R FN2 tuning who’re prepared and prepared to take efficiency to the subsequent degree. Whether or not that’s sticking to the FN2’s naturally aspirated roots and crafting a throttle-bodied, 9000rpm-screaming observe weapon, or including some increase to create a brutish forced-induction fast-road monster able to go supercar-hunting, the FN2 Kind R can do it and may do it effectively.

Right here’s what you ought to be searching for when tuning your Civic Kind R FN2.

Civic Kind R FN2 Engine Tuning

The FN2 Kind R’s 2.0-litre K20 engine kicks out a reputable 198bhp and revs proper spherical to 7800rpm with out fuss. These are spectacular numbers for any sizzling hatch of the time however are significantly hanging for a natural-aspirated 2.0-litre; the Ford Focus ST of the identical period solely produces 24bhp extra from its 2.5-litre, turbocharged, five-cylinder engine!

However therein lies the FN2’s greatest drawback in relation to efficiency tuning; it’s already so effectively optimised from the manufacturing unit that you just gained’t see the identical big features different vehicles take pleasure in from easy bolt-on mods. That mentioned, there may be nonetheless much more to come back from the K20 in case your tickle it in the suitable locations.

There are two distinct routes to tuning the FN2’s motor: persist with naturally aspirated tuning or do what Honda was finally compelled to do with the later FK2 Civic Kind R and add some increase.

Remapping

Die-hard followers desire to stay with naturally aspirated tuning to retain the FN2’s rev-hungry character – it’s the final of the screaming VTEC breed in any case. Due to this fact, Civic Kind R FN2 tuning usually begins with a remap for round £500 – which, in contrast to the earlier EP3 Kind R, may be put in by way of the OBD2 port on the FN2, making Kind R tuning a lot simpler.

Don’t count on large peak energy features although; an additional 15bhp or so is all you’ll get from an in any other case inventory FN2. However that’s not the purpose at this stage; the principle advantages of the remap are extra mid-range torque and a decrease VTEC crossover level, getting you onto the extra aggressive cam profile sooner for added urgency.

Efficiency Exhaust

To take advantage of the remap, efficiency {hardware} will probably be wanted. The primary restrictions right here, as ever, are inlet and exhaust programs.

Naturally aspirated engines are significantly delicate to exhaust tuning, and a cat-back system by itself does little greater than enhance the soundtrack on an FN2. As an alternative, for any significant features you’ll be a efficiency 4-2-1 exhaust manifold from the likes of Tegiwa, Japspeed, or Toda Racing.

Costs vary from round £350 for the Japspeed merchandise, to over £1500 for the Toda Racing package . Add a sports activities cat (or de-cat for observe vehicles the place highway legality isn’t a problem) and a cat-back system to finish the package deal. Japspeed and Cobra Sport provide 2.5in (63mm) programs for the FN2 – the previous costing round £550, and the latter £850 – however many tuners desire the bigger 3in (70mm) bore of the Tegiwa cat-back exhaust, which is obtainable for lower than £500.

Consumption Tuning

Subsequent up you’ll want to take a look at getting air into the motor quick sufficient to match. Changing the inventory airbox with an induction package is your subsequent transfer, and there are many choices to fit your price range. An Injen chilly air consumption package will set you again £350, however you may spend as a lot as £1000 on the Mugen package. The Tegiwa carbon airbox (£450) is a well-liked selection, as is the HKS package (£530).

With the fundamental ideas of induction, exhaust, and remap lined, you may count on to see round 220-225bhp from the FN2. The following ranges embody including a efficiency inlet for round £500 (taking energy to roughly 230bhp), and eventually including a set of efficiency camshafts (£620) gives you sufficient to achieve 240bhp.

Additional NA Upgrades

And 240bhp is the candy spot in relation to Civic Kind R FN2 tuning; it’s visceral, full of life, and aggressive, and retains that naturally aspirated high-revving character – over 9000rpm is feasible, however you’ll need to add a modified oil pump to forestall oil cavitation at these speeds.

Additional tuning will see the usage of a bigger throttle physique, or a set of particular person throttle our bodies, and when coupled with a K24 2.4-litre backside finish to create what’s affectionately referred to as a Frankenstein engine (stuffed stuffed with acceptable high-compression pistons, beefy con-rods, and so forth) we’ve seen over 300bhp achieved from a naturally aspirated Civic Kind R. However it does begin to get very costly, and there are different, a lot simpler methods to unleash that type of energy from the Civic Kind R FN2… By including increase.

Pressured Induction Tuning

One of many best methods to get massive energy from Civic Kind R FN2 tuning is so as to add a supercharger package .The K20 responds effectively to a little bit of added increase; the additional low-down grunt works in concord with the VTEC’s prime finish. Kits like these from TTS Efficiency use the Rotrex vary of centrifugal superchargers, with kits beginning at round £3600 for parts-only. For that you just’d be trying on the entry-level, non-intercooled package with a C30-94 blower working round 7psi of increase – however that’s nonetheless man sufficient so as to add round 100bhp on the wheels.

Upgrading to TTS’s Supersport package sees a front-mount intercooler and appropriate radiator upgraded added, alongside a high-flow Walbro gasoline pump and 4-bar MAP sensor, however retains the C30-94 unit, now producing over 12psi of increase. That’s sufficient for 350bhp on the wheels – and you may push 400bhp with some intelligent use of water/methanol injection too.
Amazingly, there are even greater blowers out there too; TTS gives kits with C38 superchargers that can take the facility all the best way to 600bhp, however you’ll want a totally cast construct if you wish to run greater than round 14psi of increase.

After all, superchargers aren’t the one means so as to add increase; we’ve seen epic 500bhp-plus outcomes from turbocharging the Civic Kind R FN2, however these are customized one-off builds with worth tags to match. It simply goes to point out that something is feasible should you actually need it, although.
