Power Loss: Problem wid Exhaust?

[ANut]

Noob here.

My car is weak to the point where i cant seem to accelerate uphill, and is making an almost unbearable sound that i think is coming from 'somewhere at the passenger side between the exhaust and the engine.

I dont know whats wrong, and havent had it checked yet (apart from by my uncle) coz im waiting till uni holidays to check it when i have time. My uncle said it might be the exhaust if the car has extractors (this i dont know). Something about the emission not being able to get out and getting sucked back into the engine. I have no idea myself. But does anyone know about this who can provide some help?

Thanks.

What car?

[ANut]

sorry *stupid me* its a r32 gts rb20de stock + air filter

[NA_R33]

without more info it sounds like ur cat is blocked/what was left broke off and blocked the out hole, it does happen, just pull it out and have a look.

[ANut]

thanks NA_R33 i will get it checked sometime this weekend.

my power loss felt similar to what you describe. took off cat and it was in perfect condition (make sure you take it for a fang to hear the exhaust coming straight off the manifold).

then i cleaned the pod filter and had 90% of my power back. try that.

[ANut]

thanks Greg. will do that prolli tomorrow havent managed to check the cat yet tho. my engine is beginning to misfire since my uncle checked the engine. i kknow i gotta change the spark plugs coz they're pretty blackish. think maybe theyre the cause.

[ANut]

ok turns out. when my uncle put the plugs back in, 1 of them got cracked so theres the culprit to the misfire. currently have NGK BCPR6ES plugs gapped to 1.1 and working. yeah i decided to clean out the air filter with (dont laugh) a tooth brush

id say from my noobie analytical brain, i gained about 70% of the power back. exhaust is still loud as a mofo, seems loose and havent been able to get it checked yet so yeah. till then.

Nice work

if you could actually clean your air filter with a toothbrush (ie it made a difference) then I'd say it's definitely time to replace it. I use an air compressor to clean mine. cheers

[ANut]

yep. looking for a replacement right now.

i wanted to do that but I didnt use an air compressor coz i didnt have one and couldnt get one at the time. i decided i'd clean it when i got up on sunday (at 12:30pm :headspin: ) so no chance at goin to autobarn to get the air compressor.

Anyway. can you recommend an air filter. im after one soon. id prefer to have one i wouldnt have to maintain but anything will do really, coz it seems like anything would give me better performance

Ta!

[Greg]

i run an apexi pod, but if you just want a replacement panel filter then a few people on here run k&n so try them

[ANut]

i dont have the stock box. i got sum dodgy small pod noname. so id prefer another pod. what model is your apexi pod. and how much did it set you back.

[Greg]

part no 508-N005 ¥6200 = about $80 + freight.

try routing some cold air to the pod and making a partition - its makes a noticable difference

[ANut]

OK extractors were checked ( i thought they wree called front pipes BLEH) had a 5c sized hole in it. That was the cause of the extremely loud noise, and power loss and me having to ease up on the gas in order to change gears. didnt end up getting them replaced even though i know i should (theyre rusted really bad).

What my uncle decided to do was weld some steel around the thing and seal it up. Works a whole lot better. From all the F-words and cursing i heard from my uncle it was a tedious process (probably because we only had 1 jack). Over heated-Broken bolts replaced etc etc.

Air Filter was cleaned wid a air compressor gun, and some degeaser.

100% power is back. and i am a happy man again.
