Got A Boost Problem

[XXE-R32]

Ok i got my front mount installed plus a high flowed my cat. The car is runing stock boost and everything. but now when the car gets to 7 to 10psi (sometimes it even boosts to 14psi or higher) it jerks and mis fires and carries on. One question i have is do i need to re gap my spark plugs, or there was a nipple with a pipe plugged in to ther top bipe of the stock cooler now my new cooler didnt have this so i just blocked off this with a screw and made sure its tight

Any ideas anyone

the pressure line from the cooler piping to turbo actuator has been disconnected or is damaged/blocked/loose. basically the turbo actuator isn't opening and you are running unlimited boost. this results its massive pressure and stock ecu protection gets activated.

connect up the pressure line from the cooler piping to the actuator

DO NOT keep driving it, it will go bang and cause damage as you are running unlimited boost

So how do i fix this problem. Would a boost controller fix it, its finer till its gets over 10psi then it just doesnt like it. That pressue hose is blocked as i have put a bolt as there is no where to put it in the new piping.

Any ideas

no a controller will not fix it, the problem is the factory controller is not working as the actuator line has been disconnected. there must be a pressure line run crom the cooler piping to the turbo actuator (as it was before with stock intercooler)

yeah man you'll need to get a nipple drilled into the pipework up near where the original one used to be. As paul said, its gotta be done. My kit came with it predrilled and nipple included. I'm sure any metalwork place can do it for ya

ahhhhh sweet ok guys

thanks for that , i will get one drilled in, where would i get it done or a nipple from

i friend said i could T peice this back into the piping from the small vacumm line from the charole tin

is this right

i think i have the same problem as you, my piping didn't come with a nipple, and it was fine for the first few days, but now the car jerks and cuts power and stuff.

i had the same problem, my hybrid kit came without a nipple. get a nipple put on, connect it up, and all will be well again.

[guesty]

so you reckon that is all it will be then? why would it be fine for the first few days, i fitted the front mount and pod on thursday, and it wasn't till sunday that it started playing up.

[guesty]

well i got a nipple put in and hasn't fixed the problem. maybe i will just take it over to nissan dealership. i need this problem fixed asap

[paulr33]

thats pointless and the hard way of getting it fixed, a good performance work shop should be able to sort it out in a matter of minutes. ok so you have the nipple, so where did you connect the line to ?

[guesty]

i got it tapped in on the fmic pipe roughly where the old one was on the car, runs down to my pass through boost controler then down to the actuator.
