Hey Guys...

Total newbie here, so pls excuse this dumb question - I wanna fit an aftermarket BOV to my R33 gts-t, so in preparation I blanked off the plumb back hose. This made the engine run very rough, and a fair bit of air hissed from the factory bov outlet on idle. Will this happen when the new bov (GFB basic) is fitted? Was this normal?

Thnx

Hi there, yes that is normal, the stock blow off valve will leak air when driving off boost causing the engine to run roughly when the air return hose is not connected. they're not designed to vent to atmosphere. My car did the same thing but once you fit a aftermarket one it'll run normal again. I wouldn't recomend driving it with the stock blow off valve running vent to atmosphere either mate.

the aftermarket bov will most probably fit in the place of the factory one.

so until you have that ready to fit, unblock all hoses and leave the factory one on there as it is supposed to.

once you have the new bov, remove the stock one.

block off the big return hose.

attach the new bov and attach the small vacuum line to the new bov.

adjust it as required.

keep the stock bov..

you'll want it back soon

trust me,your car we stall,probably not straight away but it will.

everyone on here told me it would but i ignored them and stalled at an intersection and nearly got wiped out by a truck.

i don't know if this happens to every R-33 GTS-T but i have to get mine tuned for it.

am i right or wrong guys?

that's correct. it might not stall all the time but it will stall and when it does you will look like an idiot at the lights/intersection. an aftermarket MAF based ecu can be tuned to cover up the issue or a MAP based ecu which wont care what sort of bov or if you even have a bov on there.

So true.

Hehe! Yep.

yup, they're right. yet if you manage to boost your car high enough for the stock bov to give in, buy a GTR bov. problem, solved.

True, I know the stock GTR BOV can handle over 300kW if not a bit more with no problems.

    • Am I correct in assuming that the R35's are getting the classic skyline haircut off the odometer?  Quick search on carsales, there are 33 08 and 09 GTR's for sale, only 2 of them have more then 100,000km's on them (116,075 and 110,000 respectively).  And somehow there are about 25 for sale with around 60,000kms? Looks like the classic skyline haircut to me =/
    • @Stringycheese  Have you only gone to the one blue slip workshop?  There will be a heap of them where ever you live, good odds that the next place you go to will pass the car.  Unfortunately (or fortunately?) every blue slip / engineering workshop will be different and will be happy passing or failing different things - despite working from the same set of rules. It's kinda like 2 lawyers arguing over a piece of legislation, each saying their interpretation is correct. Might seem strange that this happens when it comes to getting a modified car passed, but this is very much a thing. A big part of the game is finding an engineer / workshop that is on the same page as you.
    • Bah. I daily mine. ~60km per work day, 10-12 thousand km per year. What's the point of having a dirty old Datto and leaving it in the shed. It needs to be driven and enjoyed while the govco allows us to do so. It will only be a few years before we're forbidden to even start up internal combustion engines.
    • Judging by that spring perch and the normal looking spring on it - not a coilover. Well.... it is a coilover, just a stock format coilover, rather than what everyone calls a coilover.
    • Yes it is. We get stock from Nismo directly. I'm happy to take photos/video of it as proof before I ship it with timestamps or whathaveyou.
