what mods to gain more KW?!

[KaZe-]

Hi ALL,

i wanna know what i can do to add more kws to my car and ppl have said that

injectors

extractors

exhust *dought it will help our car*

manifold

clucth? not sure

i wanna know if any of these items will add any KW's at all ?!! and if so how much and wat brands would be the best

Cheers Steve, :)

If ur serious bowt power I would get K&N filter on a TRD or AEM CAI system, performance throttle body, new ecu n powerchip, ported and polished intake manifold, TRD extractors, full 2.25" exhaust system (mandrel beant n ceramic coated) and TRD clutch. (but im guessing u would already have some of this stuff)

But that is gonna cost u big dollars. If u r dead serious bowt performance (irrespective of cost) I would also look down the forced induction path (a small turbo or sumfin) but if u r gona do this make sure u dont get extractors prior to this as u will have to get rid of em in exchange for a turbo manifold.

Hope this helped.

i got a trd and k&n filter it sux balls.... any way how much for the rest i mean lyk injectors and manifold and clucth?? what are the gains exactly??

im thinking more along the lines of injectors with spark plugs my mate with his 180sx said that would help a bit but not sure how much it would cost and how much kw gain it would give and a manifold or somthing extracters and a light clutch just want an avarage price and how much kw gains it would give and also i dont think i would want a exhust too loud and annoying i reackon lOl ill save forced induction for my next car oohhhh yeeer!!

Soz bro i got no clue on exact prices. U will hav 2 talk to a place that specialises in porting intake manifolds (dont just take it to any old stooge). Injectors i dont really knoe much about.

Man u would b surprised if u put extractors n a 2.25" inch exhaust system (including high flow cat) at the gains u would get becos at the moment that is ur bottlenek (if u noe wat i mean). Wat i mean is since u hav CAI n pod filter ur air intake is prety free flowing (all u could do is throttlebody and a port + polish of ur intake manifold) but since ur exhaust is stock it is restricting the flow of gases out of ur cylinders which means even tho uv tackled ur air intake it is ur exhaust system that is holding bak the gains u would normally hav on a poddy and CAI. This is becos from the factory car manufacturers to a certain degree hold bak on highest performance with the outlet manifold so that they can put it in afta the engine n all other pipework n so forth is mounted (for cost reasons), therefore if you replace this with extractors which are designed for optimal flow n r a bit tougher to install u will get higher gains. And with exhaust systems car manufacturers often sacrifice power for gas emissions restrictions which they must follow in stricter countries (such asjapan who signed the kyoto protocol, as well as Europe who hav there own tough restrictions such as Euro 3 and Euro 4) therefore if you get these replaced with an exhaust that focuses on performance you will get powr.

if you are very confused by all this read some net articles such as this:

http://www.magictuneexhausts.com.au/exhausts.asp

As for the approx. gains u would prob expect round 10-20+kw higher than stock if u do pod air filter + CAI + throttlebody + extractors + exhaust, depending on ur choices. Although dont quote me on this as im just estimating from wat iv read and spoke to ppl about. If u want really high gains tho u hav 2 replace ur computer chip (ecu) but note wen u do this ur fuel consumption will significantly jump. If this is an indication I noe some1 who did up his pulsar SSS (SR20-DE engine) with all the usual pod air filter, CAI, extractors, exhaust and ECU + some other stuff i cant rememba n he claimed to do 150kw (from a stock 95kw or so). But his fuel consumption was also feckin massive.

index your spark plugs..

[MR22ZZ]

Look at your A/F on your Dyno... are you leaning out up top? no? Injectors will do SFA unless you can stuff more air in there, and for that you will need to go Forced induction!!!

wats index and sfa??

[MT]

indexing your spark plugs... its an old trick... actually has produced proven gains on a corolla. remember neils corolla that went to Germany??? made kw gains at the wheels from indexing the spark plugs... not much but still a gain.

SFA??? Sweet F*ck All

How do u index ur plugs?

What Is Indexing? | Back To Top

Generally speaking, the idea of indexing is to position the spark plug so that its gap is facing the center of the cylinder, angled slightly toward the exhaust valve—the most common arrangement. (Some engines work better with other gap locations.) This is important because, as the piston approaches TDC, the air/fuel charge is being compressed. The charge or "mixture" is being forced toward the area of the spark plug—and normally, the exhaust valve. The true speed of this force inside the combustion chamber is extremely fast. Some experts speculate that it surpasses supersonic speeds.

Because of this, the spark generated from the plug should be in a "position" to create the best possible flame front. Looking at a typical side-gap spark plug, you'll note that the electrode can actually block the flame process. On the other hand, if the electrode gap faces the on-rushing air/fuel charge, it stands a much better chance of igniting a flame front.

How To Index | Back To Top

How is a spark plug indexed? Simple: Mark the spark plug insulator body with a felt marker (never use a pencil, which acts the same as a carbon track inside your distributor cap) on the side where the ground electrode attaches to the spark plug body. Instead of rummaging through boxes of spark plugs to find the elusive combination of perfect plug threads that match the cylinder head threads, use indexing washers. These soft copper washers are available from the aftermarket and will fit both flat- and tapered- seat spark plugs. They're available in three thicknesses: 0.060-inch, 0.080-inch and 0.100-inch.

Copper's inherent softness along with the various washer thicknesses make it simple to thread the spark plug into the cylinder head and tighten it to the point that the index mark is situated in the correct position relative to the combustion chamber. (Never double up washers; they aren't intended to be used in tandem.)

Power Gains | Back To Top

Real-world power gains vary. Some engines or combinations respond differently than others. In fact, all engines will pick up power, but some gains will be more dramatic than others.

In the end, it can't hurt to index the spark plugs. This can contribute to superior engine efficiency and improved economy.

ok...on the cheap i would say...

see if you can fit/mount/attack a leaf blower into your intake and have it remotely triggered from the cabin. So when you feel the need for a few extra horsies you crank up your blower and cram a couple of pounds of air into your throttle body, should yield a ~10% power increase depending on the blower. Seriously.

Cai

Extractors

New cat back

clutch

pfc

[sportiv]

sorry i didn't get back.. but micky-tee pretty much summed it up.. its a prick of a job to do and if done correctly will yeild better torque figures.. haven't done it yet but ive been speaking to lexus peoples about doing it apparently on the 4-age and agze's the results are quite substantial

[vyets]

get weapon R headers and run a custom straight pipe no cat.

apexi power fc

if u wana be street legal

2.5" custom mandrel bent exhaust.

port your headers they give best gains for a 2zz

u can try bore out ur throttle body not 100" sure on the gains but if u have money buy the trial throttle body

apexi pfc

FI route, blitz compressor, greddy supercharger, c2 turbo kit lol :P

or get a turbo car =D 2zz sucks lol

and steven dont forget that 180's are powerd by a power making machene sr20det turbo gets gains so easily compared to us.

Buy the EVO

[KaZe-]

waiting for my income >.< end of next year i hope

[ar44]

Firstly, you could look into stroking the engine to 2L's. However, if your going to buy an evo in a year, my advice would be to stop pouring money into your sportivo and put up with it for a year, chances are you wont get your money back from the mods you spend now. Then again you could look at buying something else now and put off purchasing an evo for another few years. Why not a earlier model evo 6,7,8 or S15 200sx?

[KaZe-]

well while i got the stivo i might aswell pour money into it or i wont be satisfied driving it >< and i wouldent mind a 7,8 or 9 but i would perfer a 9 if possible and this probly lame but my mum dont want me to have a 2 door car so yer... >.< or else i would have got a typeR instead of the stivo..

Steve,

[ar44]

they money you save on not modding the sportivo, can get you closer to an evo:P

[KaZe-]

yer i know but i dont wanna be crusing in a crappy stivo!! :P

[Dead]

F6 Typhoon then Steve. Has four doors and a 270kw 4.0L 6 turbo putting out 550nm of torque (that torque figure puts a GTR to shame even) ;)

Buy that and truely own everyone haha (unless you get owned by your insurance company first :S...that's the only thing that scares me).

[BanGn]

get a nice intake..

race pipe

clutch

semis/ full slicks

and learn to drive :P

[ar44]

Out of interest has anyone fitted the TRD high compression pistons to their car? TRD boasts power increase of nearly 15kw and 20nm's?

Don't bother, what you're really after is more torque rather then more power (KW). and that is not something you really get out of a high strung NA engine like this one.

You can follow all the advice on these threads, and throw money at it but at the end of the day, you will not get the driving feel you want coz the way i see you write, you need the feel of F/I to be happy.

Instead of forking out bit by bit on little things, why not just do it at one shot and get the blitz S/C kit for the stivo?

Or just hold on and hope it doesn't depreciate that much and go F/I as soon as possible.
