i owned a e28 wif rb20det, i sick wif my turbine, now using the third...stock turbine..
everythings i boot up my car feel like N/A, first and second turbine spoiled coz i din change a good exhaust system for it...
coz of my frenz told me my exhaust system too small.. now using 2" paiping and 4-2-1, need help guys..i can't every speed it up ever i drive turbo... ish... sumore scare the turbine spoil again...
pls guys... teach me wat to do

yes... your piping does sounds too small for a 2.0 turbocharged....and what's up with that 4-2-1? turbo engines use turbo manifold. turbo manifold does not have 4-1 or 4-2-1... the four extracting pipes just go into the turbo.

you should go at least with a 2.5" piping, and get a good performance muffler.

get an original HKS/Tanabe/APEXi/Trust... no imitation please... they wont last on your turbo car.

my friend had stock GTI exhaust on his 4G93T GTI.... within 3 months after swap he already broke his turbo.... bad backpressure.

I think if you chnage your original standard muffler to 'true' performance muffler, it should have some very slight performance increase, as I read in HowStuffWorks website, mufflers tends to give "Back Pressure". So, if you installed the wrong muffler, you could exprience loss in power...

I guess that explain why certain "Ah Beng"s cars sound so loud and noisy but the car still there... Even those cars like Evos or Subarus with bad modification, the sound dem loud (uh, it's noisy and not nice) and the car like no power.

the best performance would be no muffler

but then again...the noise is unbearable, and it's against the law having damn noisy exhaust

just a question..how much do the parts in the tutorial costs?can u guys put it in the guide as well?

guys, i'm wondering whether is it safe to use the chapalang open-pod air filter...
i installed the mushroom since last year... but till now it seems to be clean.. (not many dirt though) ...
wonder how's the filtration rate....
btw, my mushroom is chapalang brand (RedLine)..
while the filter element is somewhat stainless steel netting... , not sponge/paper or watever..

Actually, is there any open pod KNN filter for wira efi type airbox?

well... you can actually install a custom ram pipe and add open pod K&N

HOw bout a drop in KNN filter for wira efi airbox? is there such a thing for sell in Miri?

hi guys, first of all thanks for the article soulfly. My knowledge considerably improved after going through this thread. Anyway, where can i get PowerZone 4-2-1 extractor here in Ampang? or anyway nearby? For RM 400, changing the extractor seems like a good price for a noticeable increase in performance. Probably ive missed this point as i was browsing through, how does changing the extractor affects the fuel consumption?

BTW, I drive a gen2 1.6 manual.

i was reading in another forum sumwhere... they said..for wira se...can change to open pod air filter without replacing exhaust and etc..issit true?

Any car can change to open pod air filter without replacing anything except the OEM airbox and perhaps the ram pipe.

hi ...i have a question here...actually mod exhaust is legal or illegal wan?? thanks

i had read through the rules from jpj websites..but they never stated mod exhaust is legal or not....

its legal when:
- piping still follow ori route [no straight pipes]
- muffler that doesnt sound like a meriam

well, that what the officer said when i got my summons

hi, anyone know if Corona ST171 original extractor is ceramic coated? Mine looks cracked.What kind of effects does it caused if theres a crack? Mine has like vase/pot cracks.

Sparepart shops that carry genuine K&N filters might have them. I'm not sure which shop, but probably you can try ask Siong Fah (Krokop).

Cracked extractor is dangerous if it leaks exhaust gas. Just imagine how hot the exhaust gas there.... and it may cause power loss as well.

If it's just minor crack lines then it probably still okay, but recommended to be replaced to avoid any unwanted problems later.

Soulfly,

any recommendations of extractor brands? How much nowadays the extractors...is hotbits good...or custom "ayam" brand..

Powerzone, hotbits, zenden~~

Zenden and hotbits basically is the same

Thanks bro Soulfly

oooo thanks thanks...i ask eneos to survey price..they say 300 for the hotbits extractor..+ 100 to install..expensive?
