hey guys got abit of a problem

this morning i put a new 3 inch intake arm on

blocked off the bov

dont worry i got pics

now theres a small hose which i believe is going from the top of the boost solanoid (correct me if im wrong sorry for the silly questions)

and that use to run to the old intake piping

now my dillema is the car stalls if i do sudden stops i got to ease it in, and im getting a loud pop out of my exhaust when i de-accelerate

would me blocking off this hose that use to run to the intake cause my stalling or is it the excess in back pressure cos i got a stock cat and there after i got 3 to 4 1/2inch catback right behind it causing a bottle neck due to the increase in backpressure and power?

Just remove the whole stock boost solenoid all together and run the hose from the inter-cooler piping to the wastegate.

It shouldn't matter with a stock cat either....im guessing it was fine before you blocked the BOV?

Not sure what that hose does that runs from the boost solenoid to the intake pipe though....I had it on my 180sx and removed it when I removed the stock solenoid.

It could be a build up of pressure inside the intercooler piping thats trying to escape through the turbo and causing the car to stall??

Maybe reset your ECU for it to remap itself as it would be running richer without a BOV

thanks for the input mate :)

which hose are you talking about ? one i took off the top of the solanoid? (i blocked it off with a bolt in the pic)

sorry for the dimwhit questions :P

yeah it was popping before but not when de-accelerating and dropping gears

only popped when i was changing gears from 7k rpm

Hmmm....

chyeah got me stumped,

just took it for a run for 30 mins didnt stall once but reduced popping during decelleration but still there

and just stalled in my drive 4 times lol

Your car is stalling because of the BOV being removed, it's a well covered topic mate...

Need Nistune or aftermarket ECU, then a custom tune to tune around the BOV blockoff. Stock ECU expects the compressed air to be otherwise re-circulated through the intake, what is being measured at the AFM and what is actually reaching the engine is why it's stalling and running like crap.

okay sweet thanks mate!

i heard getting a decent tune is around 700 too 900 through nistune but not including the piggyback ECU

    • That still isn't a lot to go on. I don't have a Y50 Fuga Head Unit wiring diagram. I can say that a lot of nissans of that age shared head unit plugs, so if you are in Australia something like this would probably help: https://aerpro.com/app091# You plug that into the car loom, then either plug the head unit ISO into that (if it has ISO), or you buy and ISO adapter harness that you wire in. Bit of stuffing around, but once you have ISO its easy to change things in future.
    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
