Have a t66 single turbo setup 1500cc injectors apexi ecu...
Major boosting problem. Every time the car boosts and pressure builds up it hesitates cutting boost on and off viciously??!!
Anyone have any idea where i start
Sounds like a fuel or ignition cut to me? Might be best to put up the specs, im guessing you are using a 3 bar MAP sensor etc?
I have no idea about map sensor etc. i didnt build the car i brought it how it is.
This all i know
1500cc injectors, external waste gate, apexi ecu + commander, fpr, t66, nitrous
hows does it idle and run off boost
I\'d ditch the nos straight away
It runs fine off boost idlea fine. The second the turbo
Nos is never used
Is there any where near gloucester that i could take this to? Its not boosting at all now. Soon as boost trys to cut in it just splutters.
And maybe get map and fuelling checked before something lets ago
Okay im not a mechanic by all means but is there any chance my spark plugs just arent keeping up with the fueling?
check the clutch, try to pull away with the hand brake on and see if it tries to move. It\'s probably not the issue but an easy check to rule it out.
mate had very similar issue. turned out to be faulty HKS twin spark.
100% not the clutch that would be slipping. Im going to buy some hks plugs does anyone know the beat place?
Anyone know where to get hks spark plugs?
doesnt need to be hks plugs. pretty sure theyre just rebranded ngk iridiums. just go to any decent parts stores and they should be able to get decent heat range ngk plugs.

You sure, mine did exactly this, and was a nightmare finding the fault.
It had a 3 paddle clutch fitted 600 miles ago. When i was driving the car my friend following said when it was trying to boost it was spitting flames out.
Thing is i brought plugs last week ngk platinum ones because the car would even start from could and ever since i\'ve had them in i\'ve had nothing but problems it seems. So i managed to hunt down new hks iridium plugs for 14 quid each which i think is a decent price also brought new leads. Once i have fitted that its going for a re-map. Hopefully fingers crossed that should be the last of my boosting problems
examine the clutch i465 black, try to take away with the side braking mechanism on and see if it tries to shift. It\'s probably not the problem but an simple examine to concept it out.
Clutch is fineeeeee!!!! Its 100% a boost problem. The boost has gone from spiking bad to worse and now not boosting what so ever. Just fitted new hks plugs and leads and still the problem is not solved. Really p*ss*ng me off now. Is there anyone near gloucester/bristol/birmingham that i can take my rx to that can help. I have a funny feeling that my external wastegate could be causing this problem. But would prefer letting someone that knows what they are doing with rotarys to have a look?!
Hi guys still got this boosting problem.. cant seem to find the problem . i have taken the wastegate off checked it and changed plugs and leads, still no good.. just splutters as soon as boost comes on. doesnt boost at all.
does anybody know the best place to take it to near gloucester or not too far if poss?
