Hey just put a new 6 boost manifold on my rb20 an did have a cheap chinesse manifold on it an the car sounded deep an tuff as but now with the new manifold it sounds a bit like a hyundai note which is pissing me off.Only other thing ive done is mount the wastegate down near the bell housing.Im goin to hav to put another muffler on it to take out the ricey sound,anyone had similar issues? thanks running a gt35r an 45mm progate if that helps..

Never mind the sound, what's the difference like on the road?

As for the sound you dont want to sound ricey, just took car for a spin then boost doesnt seem to come on earlier but it does a little more voilently,pulls real strong.It has made 402rwhp so ill put it bak on the dyno an see if there is any difference with the 6 boost.

Have you spoken to Kyle about it?

Maybe you had an exhaust leak before so it sounded 'tough as' but now it's actually working properly it sounds 'normal'??

exactly what i was thinking

soon as i saw "chinese" manifold and a "deep note" i thought - crack/leak somewhere

Im goin to hav to put another muffler on it to take out the ricey sound,anyone had similar issues?

Sorry dude but I just have to point out the irony here...Isn't making a modification just to acheive a cosmetic outcome, 'rice' in itself...

Hahahah

True, though i dont think thats entirely what hes doin.

I think what hes saying is that hes pissed that a expensive manifold sounds worse than the original cheaper one.

6boost manifolds that I have heard result in a more tuned pitchy note, sounds awesome. If you don't like it - give it to me :P

Mine certainly did, went from an Internally gated GT3540 on standard manifold to 50mm externally gated 6boost setup and the sound difference is amazing.

Screams rather like some of the old group A cars do.

Funny i had the same thing happen to me.

Cheap china manifold= tough RB sound.

Then put on a 6BOOST item and things quiet down a bit, i put this to the smoother runners and design of the 6BOOST manifold.

Then i put on a HKS 3.75inch exhaust, now it sounds tough again :P

Definately not knocking Kyles manifold mate i tell ya well you guys no this is a work off art.I havnt had a chance to really go over the exhaust an check for any leaks but this can only be the cause,its hard to notice it at idle its only when at cruise under exceleration which leads to an exhaust leak somewhere.ill suss this out first thing in the morning.

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z

    • Wanna rewrite all of that in, say, 2 or 3 separate sentences, so that we can read it?
