If its a popping noise, and assuming its around 4500 - 5000k, your engine is missfiring.

What u need to do is replace your sparks plugs, but get them gapped down from 1.1mm standard, to 0.8mm (this just makes the spark stronger as is doesn't have to travel as far). Also, if you still have the problem, you will need to look at replacing your coil packs. Splitfire is the way to go, check out Slide Performance.

mines doing the same thing - but i already have splitfires and just put new plugs in.......im getting new plugs ordered and going from there, im hoping its not my crank angle sensor (not exactly sure on symptons when that decides to play up)

[komokefe]

yep its more of a popping noise at around 4500rpm and 5?

cheers for the help guys, will do my spark plugs first and see how it goes, and let yous know

cheers

ive gota go to NGK in adelaide to specially order my spark plugs.......noone here stocks them (sucks having to buy proper race plugs) gonna be an expensive exercise, but if it fixes the problem....360rwkw of fury will be back

[r32woohoo]

check your cooler piping for leaks, even tiny ones. just tighten all the clamps. u might have a leak somewhere

[komokefe]

even if there was a leakage on the piping? wouldnt that take an affect if you just driving normal? coz i drives fine when cruising,but go to boost the damn thing it does that?

cheers

but will take a look at the piping....

yeh my problems only recently come into effect, im pretty sure everything is good.........i mean ive driven it before and it ran perfect, then started to miss (which was infact vacc line cut from wastegate to plenum), so i though it was plugs (old plugs were gone anyway), i replaced the plugs and nothings gone right since, so all im doing is getting a new battery and the specific spark plugs i need and i should hopefully be away......i have a lot of drift practice to get too.

if i could recommend you a turbo kit and you werent shy on spending some cash......find yourself an apexi RX6 - for an RB25 these turbo's are amazing dude, minimal lag and so much power to play with

yeah might go for a RX6, not to fussed which brand!! ive had alot of problems with my car for the last recent years! its a head ache ill tell you, even my missus broke up with me coz she thought i was nuts over my recent problems with the car lol but she came back hehe,

anyways found my problem, i found a little hole in my I/C piping and i think theres another which is showing a sign of being a hole lol, can these be welded or just relpace it? ( prize wise )?

but ill still get new spark plugs thou

cheers

[komokefe]

hey guys, ive notice something today? i was looking underneath the car from the drivers side and notice the exhaust was slightly open? could that cause the problem? especially with the smell of burn fuel coming into my car?

cheers

[Nathan_G1]

exhaust leak will decrease power i think........should definately fix that problem, hole in the I/C piping, shit.....nice find mate, check over it all for any more.

new plugs fixed my car runs crazy again, cost me $75 each spark plug.........retail they were $110, THANKS FOR HELP NGK.

[komokefe]

yeah love ngk plugs aye, getting some tommorw hopefully that solves the hisatation wheen boosting, coz after getting the holes welded in it didnt solve the problem, so might check to see if its the plugs....... and plus had the mechanics check my exaust and there were no sign of leaks, BUT he said my car could be running rich coz my wastegate pipe have been leaving black mark on my exaust? lol
