NSB16A

Hey, i have a 99 si with a swapped B16A. I'm only 16 and it's my first car. I've searched around for a while but havent found anything yet. It sounds almost like a wrx. I've read that this sound is usually a symptom of a burnt valve(s), or if it isn't runnin on all cylinders. I have had the valves checked, all good as gold. Good compression all across also. The car still pulls good and there's been no power loss. Will give a little puff of smoke at vtec, but that's it. Are there any other reasons that it could sound like this?

Do a quick search in the archives type in "sounds like a subaru", its been covered numerous times before.

I checked that already, they're all in their places....I had distributor cap and rotor button replaced also(forgot to mention), didnt help. I'm new to it all...and lost.

any Check Engine Lights?

NSB16A

None

are your spark plug wires in the right order? did this just start or did you get the car like this?

oneludesol

Does the car have an aftermarket header?

x2 on the firing order, i've seen that do it a few times.

The car was like this when it was bought (May). It does have a megan racing header ( with full tsudo N1 exhaust)

it could just be your exhaust/headers. (just a tip since your a trial member you only have 1 more post for the day)

oneludesol

my money is with a crack on one of the runners of the header... Have seen this a few times.

NSB16A

Sorry, but what do you mean by that?(I'm aware that I'm only allowed 5 posts) What part of the header is the runner.Never heard of that. Guess we learn something new everyday. Thanks for the help so far guys

Just out of curiosity, what do you mean when you say you have a '99 Si with a "swapped B16A"? Was the motor simply replaced for some reason?

oneludesol

I think there is a crack in one of the runners of your header... take the header off, and look at it very carefully all over.

You can only post 5 times a day since youre in a trial membership for about a week. You can't post anymore within 24 hours but you can still edit your posts to type something in!

up here in canada the si model has the d16y8 or z6, unlike you guys in the states.

if its a 2 piece header... check to see if there is an exhaust leak on the header...

i have a 2 piece kamikaze header and when the gasket blew the one that is between the 3 bolts on the header my car sounded like a WRX too...

I have heard pretty bad things about Megan headers (i.e. cracks) if thats not the problem i would still keep in mind to replace it.

Oh, I didn't notice that he's in Canada.

pull all of your injector plugs off 1 at a time and if the sound doesnt change at all when you pull 1 off or another off thatll be your prob. i had the same exact sound when i rewired my injector plugs to in stall new injectors. was there any wiring done on the car in order to facilitate the swap?

is the ecu chipped ?

i agree check you injector plugs more than likley one isnt all the way on there... other things could be a bad spark plug....

I have a friend in New Glasgow with a 91 hatch with a b16 swap in it. It sounds like a subaru as well. Car runs perfect (14.7 @ 93mph). I think his is because of the 4-1 header on it. No need to fix it if it isnt broke IMO.

I have a jdm b18c-R swap with megan 4-1 headers, test pipe, and full 2.5 megan "drift spec" exhaust. And it sounds like a WRX, runs perfect..

replace spark plugs and wires is step one. or make sure the wires are plugged int
