Speed Boost / Performance Increase without Turbo?

[Tsirpas]

Out of curiosity, what are some other ways I can increase the hp and torque without installing a turbo and paying thousands to adjust my engine with.

I-H-E,

Intake, Header and Exhaust.

You could also consider getting Hi-Cam, Big Bore Throttle, getting

lighter rims as well. Heard from somewhere that 1 lbs loss in rims = 7HP

[Tsirpas]

Lol I feel stupid asking this, but what's a header? (I got a CAI already) and I'm looking into an exhaust system.

its the pipes that lead from the engine block to the exhaust

[Tsirpas]

Never knew/thought about that, thx for the help! Looking into buying one now (used). lol

But this IHE combo will make your car fart hell a lot louder, fyi.

Cops might pull you over if you rev up high around them, lol

also if you know how to rebuild your engine like polishing heads and everything inside etc you could get atleast another 50hp
Also getting engine torque dampers, ecu performance chip.

Buy another car? Tires

By the time you mod and tune and mod some more, you'll spend more than the mazda 3's value.

The returns on investment are poor IMHO if you're looking for more power. The best these mods can do is improve responsiveness, quickness, more top end room.

Rip out the rear seats, passenger seats, door cards, airbags, sound deadening, air conditioning, radio headunit, excess plastic, spare tire. There's a good 500lb's of waste in our cars.

Ripping stuff out doesn't cost money, and definitely will be a huge boost.

156hp on a 2900lb car can become a 156hp on a 2400lb car.

[oasis100]

agreed..
changing your power to weight ratio will improve acceleration times much more than any other non-turbo mod..

[Gizzmo_jr]

Start a new credit card and order some NA parts from Ford Cosworth department. Convert to cable actuated (from fly-by-wire) and get the big bore TB, intake header, BSD, etc etc

[MistaChin]

definitely altezza tail lights and some NOS stickers

[Thrizzl3]

would light weight pulleys work too?

are all of the 3's fly-by-wire throttle? and what disadvantages do they have over cable actuated throttle?

[whiteomega]

Yep. they're all drive-by-wire throttle.

The computer controls things to a finer point, but the disadvantage is that you no longer have direct throttle control. your inputs go through an electronic committee, rather than directly to the throttle body.

[froggy]

thought as much. lol and I guess it's pretty safe to assume that converting to a direct linkage and a different throttle body would completely void my engine warranty. lol only 4.75 years to go before i do that mod

[Donutz]

some NOS stickers

That has to be good for 20 hp at the wheels.

There are a couple of things to think about; making more power, and putting the power you make to the ground.

Some of this is redundant, however:

I/H/E
motor / tranny mounts
those darkstar (medieval) suspension bushings
lighter wheels / tires
bored out tb
port / polish
thinner head gasket
intake mani
Rebuild your engine for higher compression; EMS.
light weight pulleys

And don't forget that dodad that makes the pshhh sound!

I think the deciding factor is how much coin you have to spend, and what your tolerance for potential downtime / breakdowns is.

In Australia you can get a cable tb.

a set of light weight pulleys

[Zoom Zoom Boy]

Just do what the Honda guys do and throw some 'Mugen Power' stickers on the car. Should be good for at least 100 more VTEC points...

Failing that, yes, intake, DP and muffler, or just buy a friggin' MS3 already...

[darkstarmotorsports]

^^^lmao!!

or lose 500lbs off the car.

the 3 at 2400lb's would be soooo awesome. That's honda fit /yaris territory but with 156hp plus whatever mods intake dp head exhaust, maybe 170hp

170hp on 2400lb would be freaking awesome and quick.

i'm tempted to shed weight off my car. going to make a new thread

[condor888000]

500lbs is a hell of a lot of weight to lose man.

[bhrm]

500lbs is a hell of a lot of weight to lose man.

Rear seats - 150lbs
spare tire, jack and tools - 50lbs
trunk trays - 10lbs
passenger seat - 75lbs
airbags all 6 - 60lbs
plastic interior - 100lbs
floor mats - 10lbs
sound insulation material - 50lbs?
sound system include all 6 speakers - 20lbs

[condor888000]

Do that and it better not see the street. The pulling the airbag would be my big concern. Not to mention the fact you're now driving a very large one seater.
