any other ideas?

no BOV, i blocked off the stock recirc. but the way my engine is now was the way it was before i had this issue, so somethings deteriorated. only thing i can think about was that wastegate issue i had, i fixed that, but even so this started well after that was changed.

yeh but im pretty sure ive had a small miss on idle the whole time, it may be normal. wouldnt worry about it if it doesnt affect acceleration etc and its only on idle.

ok so turns out the stuttering and missing were different issues from the breaking down, there was a small leak in the piping which i fixed which got rid of it breaking down, but the missing is still there although i have to say its not as much of a concern than breaking down was. so now ive gotta figure this missing out, not sure what to try next now

might be interested if u can get some photos up and check the width and offset.

can i chuck some dry ice or some bs in my intake so i can see any leaks? or could dry ice do damage for some reason? i got a smoke machine if need be

haha yep im keeping my eye out of rb25/30's just incase but i think the issue wont end up being major.

ahk its just the way u said fireworks show i thought id be able to see something pretty easy. i had a close look and couldnt see anything still. i dunno, just seems weird that all the coilpacks would go at the same time, when it hits 5psi its not just one or 2 cyls that go, the whole engine breaks down.

oh fark, thats not good news lol

1: yep, its just i dont have access to a tester and i dont have much $$ to throw around for stuff that doesnt need to be done, so id prefer to rule out other things first 2: only problem there is they are definately all sparking on idle, how well not sure but there is no obvious miss there so testing this would be hard. they only start to break down under load, only thing i can think about is chucking it on a dyno and checking it then. 3: just replaced the plugs, ones that came out were ok and were BCPR6EY gapped at 0.8, same as the ones i just put in. 4: u mean AFM im assuming, yeh i was gonna give that a clean for the idle issue, but i didnt really think it was the source of this breaking down issue. 5: like the comp test i wanna make sure its not other stuff before i fork out the $$.

just took it up then, had a look and couldnt see any sparking :S hasnt got any worse, still seems to break down at 5psi. and it feels like more than one cylinder, not like a loss in power but an actual break down and it just chokes and cant go further, if u keep ur foot down it starts jolting violently. could it be injectors maybe? or still rekon its coilpacks?

yeh this definitely isnt a heat issue, ive had a heat issue before. might be interested in the coilpacks tho, sought through them and find ones that dont have issues. chuck me a PM when u find them and ill probably take them off ur hands. are u in SA? if not would u be willing to post them? pity i got on the piss tonight and couldnt end up driving it up and checking it, ill do it tomoz.

size and offset for wheels?

ahk, yeh i dont use the coil pack cover, havnt ever noticed and sparks might have a suss tonight.

haha nup, i took of the crossover pipe and strut brace and everything, it was just as the back where theres a few hooks and cable tie ends where they have been cut (the worst) sticking out, as well as my dodgey aluminium can recirc valve gasket i made which stuck out of the BOV and often into my hand. i hate working on engines, suspension i can deal with, everything else i can deal with, but engines, nope.

eh, couldnt get it to miss all the time, just when accelerating a bit of dodgeyness and at 5psi massive breakdown, so couldnt isolate the cylinder right now. might just try swapping some coilpacks over and see what it does.

what do u mean by siliconed them? i think ive heard of this before but not exactly sure what it means. ive got a few spare stock coil packs i can chuck in. i think im going to isolate the cylinder then try changing the coilpack. if nothing happens im going to drop into boostworx again while its still misfiring and give him another listen. and the car has just been tuned to timing was only adjusted not long ago.

the actual pipe or the clamps on the pipe? u may have to move the clamps around on the piping as they usually come pretty close. theres really not much to strut braces really, as long as they fit they will do the job. its metal holding the 2 strut towers, not much that can go wrong really.

UPDATE: the issue of breaking down at 5psi is gone after fixing a small leak it had in the int. piping. but there is still a massive power loss, along with the stalling issue as well as the minor missing under load. ok, so the story starts at a drift practice where at the end of the night i noticed a few issues happening. the first was it started stalling after coming down from over around 3000rpm, the idle control would just not catch it and it would fall down at struggle around 100rpm until dying. now at first i thought owell just some idle control issues, probably related to heat from being thrashed etc. then i noticed some breaking down at higher revs and some hesitation when i backed off the throttle, not to mention a decent lack in power. now once again i put this down to heat issues at the time, probably a coil pack breaking down or something. anyway, the next day comes and i start off with a nice cold engine, but i start noticing the issues happening again and still with a lack in power (it was spinning first up easily only a day before, now nothing. along with a general feeling of gutlessness). anyway i took it into a reputable workshop boostworx where he had a look and couldnt hear anything serious, there was a busted alternator bearing making a bit of a noise but thats about it. he recommended cleaning out the idle control solonoid and giving the AFM a spray etc which ive already done in the past to try and fix another issue i had. this issue went on for about a week and i decided it might have been plugs so i gave them a change a few hours ago, they didnt seem in all to bad nick and they were decent plugs. so there went that idea. but i thought id take it out for a drive and see if it make any improvements. so i went up a nearby road and gave it a bit of a thrash only to hear the same issue, at first it started breaking down at almost dead on 5psi in both 2nd and 3rd. then by the time i got down the hill it was missing continually and sounded really off. now for a while ive had a pretty loud tappets noise come on and off. this probably isnt related but its worth noting, im using 10w40 turbolight oil so the oil isnt thin enough to really warrant this. now, i guess the typical missing issues can be related to something in the ignition, but plugs are fine, coilpacks and igniter seem fine, but it doesnt really sound like them by the way things have happened. so i guess im just after some ideas, the main thing that has got me worried is it all seems to happen after being thrashed and given a beating, it doesnt seem to be a linear deterioration or something that happens with heat etc. but yeh throw me some ideas, cheers.

haha well, turns out i already had some in there and they werent really f**ked besides some carbon build up. so a night's work later and some cut to f**k hands and no difference. on the good side, i took it up the hill and thrashed it a bit and ended up with a car that now miss fires the whole time not just under boost. wait for new thread.

yeh ill see what the broker can do. cheers

ended up going the BCPR6E(Y) with the V design, came pregapped to 0.8mm. will post up the results when i chuck them in tonight.

alright cheers, probably have a look around tomoz, who do u know stocks these or can get them in?

ok i need some help, im running a rb20 at around the 12psi mark, i noticed at the last drift prac day my engine started to deteriorate, it was stuttering up near the 4k mark, had issues idling and would often stall when coming down from above 2-3krpm, also felt different coming from acceleration to deceleration as i lifted the throttle at high revs. now i thought this could have been heat issues with the igniter module and coilpacks etc breaking down, but it continued the next day and still having it a week on. now i got shaun at boostworx to have a quick suss, couldnt see anything serious, so my thoughts have turned to plugs. i know they havnt been replaced in a while, i cant remember what went in there as it was about 1.5 years ago. my thinking is that from the hard work the engine did the heat or something has broken down some probably already warn plugs and this is the cause of the issue. so i guess my next question is what do i go to next, ive read through the whole thread and the recommendations seems to be at base for 12psi the BCPR6ES – 8, but ive also read about the v-power and that sounds like a good idea too, and the BKR7E etc. my head is bursting with all those codes so im not even gonna bother with trying to remember what is what. but yeh i guess what im asking is what plug would be the best for me? the car does get used on the track and the engine does get a work out so would going the higher temp one a better idea? i think the gapping at 0.8 and the v-power design is the way to go for my car, but yeh the temp thing is probably what's not too clear for me a the moment.

^^yeh the only problem is most of them dont have pics up of behind the wheel
