Problem?

[SKYRYAN]

Ok first the car is a S2 R33 GTST with front mount, 3" catback & pod. In the last couple of weeks, there have been a couple of cases where I accellerate hard and around 4-5k rpm the engine has hit a limiter.

The limiter feels like a fuel cut, if you have ever been to the speed limiter in 5th gear (~5500rpm) its a bit like that. Happened this morning in 2nd around 4-5k rpm...

Anyone know what would cause this? I'm pretty darn sure it wasnt the 7k limiter.. its a bit faster then that.

Cheers,

Ryan.

CoilPacks!!!!!!

Mine did this to not long ago. If you keep driving hard it will go over that "limit" but will miss fire.

$540 from a SAU trader. Slide Perofrmance i think is where i got mine from.

what psi are you running???

could be fuel cut, is it a harder and faster stop then the rev limiter?

[ashleyr33]

Could it be boost cut??- Cold morning therefore higher boost

[SKYRYAN]

Just stock boost. It only lasted 1 second at the most... definately not the rev limiter.

I've hit speed limiter (fuel cut pretty much right?) in the non turbo and its similar to that, much quieter then a rev limiter. Like a low fast rumble..

My money is still on the coilpacks.

[shmiddy]

could of blown a cooler pipe ????

[Tofu]

had the same issue with mine.

I replaced the Coilpacks and problem solvered. Its always good to replace them and they are not that expensive. I picked up a set for $140.00 off ebay 4 months ago and they run a treat.

yeh coilpacks

[SKYRYAN]

Yeah just drove home and went to overtake someone in 2nd and it did it.. then on the freeway i droped down to 4th, then to 3rd and gave it stick and yeah it did it again...

So coilpacks eh, is it bad to drive like it is now? or can i just drive it soft..

EDIT: Wer can i get me sum coilpakz!!1!1

various traders on here have em 4sale

Slide Performance have em

or you can search the FI section for 'wasted spark' which can be a cheaper alternative and it removes the coilpacks away from the engine = cooler

[sam5709]

heres the link to sliding performance's thread for splitfire coilpacks, cheapest iv seen in australia so far

id be changing your plugs at $16 instead of new coil packs just yet.......... when was the last time u changed them?????

[SKYRYAN]

I just got the car from Autoworx about 2 months ago, ya reckon coilpacks come under warranty?

[R DIRTY 3]

Talk to paul and Alistair. See what they say. I dont think it will be warranty though.

If you do want to get them from Slide, let me know as i need to order a set for for an SR aswell. We can do 1 order and try to save a bit of freight

Cheers

[sam5709]

ryan- yes you can claim this under warranty with awn!!! what paul does is keeps replacing the coilpacks with new stock ones until it stops misfiring

[bubba]

I'd be checking all your silicon joiners.. I had a hose clamp pop off (just the clamp not the silicon) and when it got to about 4k it felt like it hit a wall.. took me a bit to figure out as it wasn't like when the hose popped right off (when it popped right off it wouldn't idle and pumped HEAPS of black smoke).

[SKYRYAN]

Those splitfire coilpacks might be a good idea anyway.. are coilpacks really easy to install? Haven't worked on an RB25 before... I assume they are under that black cover on the top of your engine?

[sam5709]

the split fire coilpacks are easy as to replace, yeh you have to take off that black cover, its about 8 screws that require an allen key,

under that is the coilpacks, just have to unclip the wiring loom they are connected to and then each coilpack has 2 screw holding them down,

just take the old ones out and pope the new splitfires in, easy

[SKYRYAN]

Sweet as and are the coilpacks what hold the spark plugs? Maybe if the sparks are old (autoworx prolly just replaced them hopfully) then ill get some of those in too.
