and another thing, if rev too much the ur FC go up sky high la, but if u rev within 3.5k, not much diff in FC

What brand of drop-in did you use?

 

[har1th7]

first thing, ur car manual or auto...

if manual - use open pod is ok, but open pod just can increase your pick up and in return, lower your top speed, same as straight piping exhaust...

id auto - jut use drop in ( do not use open pod - too much air)... auto car need a bit restriction to allow faster flow ( same concept as vacuum laa, suck & pull).... and s-type exhaust...

* must realize, must choose between pick-up & top speed.... can NOT have both... MUST choose ONLY ONE....

sorry, just wanna add.... if check engine is ok, then nothing wrong with sensors...

 

[wirahybrid]

thx har1th7.. nw i understand a bit better, btw my car is auto and the brand i'm using is jasma drop in air filter... and another thing if anybody cn help is wit my wira.... i always have the check engine light on all the time but if i press the acc a little harder it goes away but comes back wen i stay at a constant rev(ie, 3k rpm for about 5 mins) so which sensor is faulty. mine is a 4g92p and i dun hav a sensor at the end of the exhaust manifold(forgot wat its called..=( ) like the other models hav. the prob came after i did a grind valve and stage 1 pnp.. so cn any sifu out there help me out wit this prob also... thx alot for the feedback

 

[LittleWhiteWagon]

Oh dude... Jasma is pirated stuff weih -.-"
Suggest you stay away from it and get a branded one, I NEVER trust pirated stuff on my car haha

 

[BLANk]

fuh....didn't know that jasma also got drop in air filter...im so *outdated*...

K&N FTW...

if ur budget restricted...simota also not a bad choice...

 

[LittleWhiteWagon]

Haha I never buy 'Jasma' branded things UNLESS its on an exhaust

 

[wirahybrid]

really arr jasma pirated stuff??? didnt knw lor.. lot of ppl say gd 4 the price bt nvr say abt the quality...fuck... got ripped off i guess

 

[LittleWhiteWagon]

Haha chill bro, money you can get back anytime 1 , save and get a K&N lah ~~

Jasma is like SIRIM in japan, but instead of electronical devices its for engine parts I think, you google them up lah! Can find their Jap website. Sometimes it pays to do research before buying

 

[rewlie]

Bro,

I'm once used to be an active members also in myvi modder, this is the first time i hear an open pod filter with JASMA brand, go for Apexi or K&N, if you google Apexi is the best air filter beats all other brands, if pirated u know la how the production, never research one, just copy design only, they dun care either working effectively or not.

 

[wirahybrid]

little white wagon, saw ur post at thread where the guy selling c-tech braces.. so, have u used it and is it any better or ultra racing better?? i knw a bit out of topic la bt just wondering.. rewlie, i knw apexi is good la bro, using it on my wira, 3 years dy and a bit of servicing once in a while bt still going strong.... so lesson learnt, no more cap ayam for me bro

 

[LittleWhiteWagon]

Haha cap ayam parts are ok, but anything to do with ur engine try to stay away... Im guilty myself using 'Jasma' spark plug cables with grounding wires, but I bought them cause they were nice, not cause I expected them to work :rolleyes:

But after I installed it, it did give me extra power so ok lo, kill 2 birds with one stone.

I never bought C-Tech braces, however I did enquire for my Nissan since its rare. Of course they didnt have what I want so gotta custom, and more $$ fly out of my wallet hahaha

Chassis bracing as im taught, is just a metal bar to re-enforce wherever its bolted on to. It can be ultra racing, zender, Ctech or whatever brands out there, cusco, taiwan made cusco etc etc, I THINK they will still work fine.

As long as its made of a sturdy piece of metal, and its NOT adjsutable I think its ok, why not adjsutable tho?

If its adjustable theres more chance that 'bar' will flex at the adjustment points, if its 1 solid piece it shouldnt flex much

Anyways thats just my theory! I might be wrong so if any other chassis bar sifu wanna explain im okay too :hmmmm:

Just like to share some info -

JASMA (Japan) - Japan Automotive Muffler Association, its an organization that controls quality standard for japanese muffler producers. Jasma certified mufflers are street legal(SR) except for racing types(RO), and follow japan automotive safety standards.

The other "JASMA" is a Taiwan aftermarket parts company,its using the name bcoz people usally related it to quality japan mufflers, so they just "tumpang glamour" ...

Rule of thumb, if anything besides a muffler is branded Jasma then its a Taiwan "ciplak". But be careful with mufflers with Jasma tag also, original Jasma tag has a serial no..

 

[wirahybrid]

thx alto for the heads up.... and thx whitewagon for the advise... might give those cap ayam brands a try later on...

 

[Defarny37]

Does any1 know what is the dropped speed after installed jasma open pod?
Im planning to fit in jasma open pod set with myvi 1.3 manual..

Appreciate ur advice n comment..

 

[Veloc]

err . i dunno bout that but can i know what is ur fuel consumption after changing the air filter ?
mine is fully stock 1.3 auto . full tank 200km only . me drive like grandma . max rev bout 3.5k .

Dude... Full tank 200 km only that is hell. Even a faulty O2 sensor doesn't gulp like that. Why not get it checked?

first thing, ur car manual or auto...

if manual - use open pod is ok, but open pod just can increase your pick up and in return, lower your top speed, same as straight piping exhaust...

Bro.. I've heard before if auto don't use open pod. But I never heard that manual open pod and straight flow would decrease top speed? Can please explain why please? I thought it will improve acceleration and top speed as well. Using open pod and straight flow exhaust improves the breathing efficiency thus should improve both pickup and top speed...

Agree bro... The real Jasma tags only appear on mufflers and headers. Save up and get Simota la... I think its the best bang for the buck as KNN is severely overpriced...
