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

    • They’re so great that I know of someone pulling one out to go back to a sequential 
    • Hello everyone. I've recently started the research into R34 GTR front bits and running into eye watering prices. On the plus site it looks like some places make 'replacement' fender liners for these cars. At eye-watering-but-less than stock prices. I also noticed there's plenty of diffuser options available too. What I would like to know is if my following assumptions are correct. 1) The OEM guard liners are actually only 'half' the liner. They go together with the OEM brake vents which are a separate item which looks to be quite a large 'panel' that is part of the liner. The GTR bumper has bolt holes along the front. I assume the ones in the vent correspond to the ones the OEM liner does not have (circled?)   2) The V-Spec front diffuser supplants the brake ducts in the above item. I am assuming these still work with the guard liners as there's no alternate part that I'm aware of. I don't see how they go together, so I'm making the assumption that they have to, somehow. I know the center splash guard is different on the V-Spec (and is the price of the damn diffuser alone). How does the liner interact with this? 3) There's alternate front diffusers that do away with it all. Annoyingly, a lot of the clones and CF different ones... have no brake ducts on them. I like the idea of them though. My brakes get hot on the track. These alternate diffusers are a lot cheaper than plastic splash guards. I'm assuming you don't have to/aren't supposed to remove guard liners to run a diffuser. I suspect that quite a few people actually do not run the guard liner because with a front undertray you're getting a lot of 'splash' guarding anyway, and most people remove liners given they're probably running a pretty aggressive setup with a diffuser at the front. It would also be nice to know if anyone has ever run the 'reproduction' guard liners and know whether the fitment is OEM quality or "OEM Quality". Example: https://www.ebay.com.au/itm/356254671561 https://carbonetics.net/products/nissan-skyline-r34-gtr-plastic-front-wheel-arch-set Is this knowledge still around?
    • Really, effort is pretty low. You hand fistfuls of cash over to someone else and pick it up when done...   And at least this shitbox isn't drinking coolant right?  
    • And most chargers that most DIY people own would put bugger all power back into the battery between cylinders. I've always done it with jumper packs/second battery connected. And that's on any car.   Because race car, and wanting the lightness.  At least in an R33, putting a bigger battery in can at least help shift the weight balance backwards  
    • OR, Tell the Motec to STFU, you said shift, so try shifting! But then yes, I agree, more sensors needed to. Put either a wheel speed sensor, or a diff speed sensor on it. Then get an input shaft speed sensor too. (I say input shaft speed, and not engine RPM). This way, you can now also log and see if the clutch is slipping (RPM, vs input shaft speed), and you can calculate gear (Input shaft speed / Output shaft speed). At least then if the gear position sensor fails you have a backup. And realistically, the Motec should only worry about what gear you're in for the parts where I'm assuming you have some power management strategies in it for the lower gears. (IE, lower boost, maybe different throttle curves, different ignition curves, etc etc). But it should stop it shifting. Pull the flappy, that f**ker should just attempt the motion! Heck, even on a sequential like on a motorbike, you can keep trying to kick it up a gear all you want, the physically part of the box takes care of not being able to loop the whole way around the box! Only part you'd have to worry is how it gets to reverse.  But that's on the driver... An R32 shouldn't be so smart as to try and override the driver on a gear shift
