My first post on here, I've had the car since January and recently started doing some mods to it. So far I've got Tein street advance coilovers, Progress rear sway bar, Rota slipstreams 15x6.5 and federal 595 rsr 205/50. The car handles great compared to stock but I'm looking to get some more go fast bits in the future. What's recommend to get some more power out of these? Nothing crazy as it's my daily.
To start, I would do a hard-core tune up to get you back closer to factory power. Depending on car's condition this can make a huge difference in power and mileage. Also very cheap to DIY.
There are plenty of good threads to research. Steps might include depending on your mileage:
- New spark plugs (check recent threads as spark plugs tend to eject and destroy heads. there are new spark plug torque specs for some engines). This is #1 priority as this is major defect that is expensive to fix.
- Do a voltage drop test under load. Clean all major contacts including at alternator, starter, main fuse panel, and battery. Clean all major grounds to body and engine.
- Have a garage or store test battery; regardless, you might want to upsize. There are threads showing how people have cut parts to get bigger batteries to fit.
- Clean MAF and ThrottleBody. Clean EGR and clean passages and PCV. Get a new air filter (get an expensive DRY type like OEM Honda or Wix).
- Check and adjust valve clearances.
- Run a few tanks of high-test fuel from one of the major Oil firms (e.g. Exxon, BP, Shell). They have better cleaners. You should be running good fuel all the time to keep injectors and valves clean. You could also try a bottle of fuel injector cleaner as it is only a few dollars.
- Drain transmission fluid.
- You should change your brake fluid every 2-3 years for max performance (and to minimize rust of internals).
He was trying to save you some heartache. Dyno results show that you're best off leaving it alone. Cold air intakes and exhaust will make it sound faster, but are worth zero to negative to very little gains.
Add boost, motor swap, or leave it alone if actual performance is your goal.
Fiting is right tho, even if you are only making power back that's still progress. This is about the stage I am with my car despite only 40k miles.
As an aside- anybody else think it's lame that keeping a Honda in working order requires frequent touching of stuff that shouldn't have to be touched? I'd never considered cleaning an egr valve in any other car to restore power...

Me either. But once I started cleaning ThrottleBody, MAF sensors, EGR passages, etc., it was obvious this stuff should be done frequently on ALL cars my family owns. No required but can make a noticeable difference in pep and gas mileage.
A lot of this is just from dirty exhaust recirculating so I suppose a good catch can could help.
The Honda Fit loose spark plugs and frequent valve adjustments are irritating. But overall, it is a good car.

Short of bolting on a turbo or supercharger, or a full engine swap, you're basically looking at better intake and exhaust to gain a few HP's. Good luck and welcome to Fit ownership!

My $1,700 engine head replacement bill can confirm that checking the sparkplugs will save you a lot of money!
Bunch of good stuff already posted. Its funny how we forget how stuff drove when it was new. Pretty peppy.
Keep her near 5k (peak hp) rpms and you can have fun off the freeway. The gearing makes top end a no go in my book.
Can recommend a bunch of stuff said in the past, most of which wont interest you.
Cut weight (volk ce28n, konig helium, enkei rpf1), 19lb tires, slotted rotors, good grease on those wheel bearings, helical LSD, bypass the AC compressor, T-REV knock-off it truly does work.
Could go with getting your flywheel shaved, and balanced with a new clutch. I wonder if you could ditch power steering.. pitman arms could save some weight how cool would that be?
Seats. Lighter.. hah, not sure if you could find a light weight harmonic balancer, if that exists.
Denso ik22s.. might be able to downsize battery, actually, specially if you could reduce resistance for the serp belt. It'd be neat to pop bearings outta those stupid pulley wheels n throw in ceramics like with a skateboard. Oh, and get a roadforce balance for your wheels

nope. Weight reduction = speed 😇

thats max torque at 4800. Max hp is 6600. The car is most fun between those 😎
but yeah the gearing is meant to live in the 3-5 range. It shifts beautifully there. When you want to shift after taching out you have to wait for the revs to drop before hitting the next gear. Drives me crazy!

it truly does work.
how cool would that be?
