I've got a R34 GTT almost completely stock and i need to replace the BOV (wont go into why). The thing is i've heard a lot of stories about installing aftermarket BOV's like the HKS and that and they give problems. I've heard of the car always stalling, the engine going, worse fuel economy and the list goes on.

How often do these problems occur with BOVs and when do they occur?

And does anyone know of the aproximate price for getting one professinonally installed to avoid these sorts of problems? (NSW)

Thanks heaps.

it has the stock ECU, only thing changed is the exhaust. I've already bought a HKS SSQV bov so thats the reason why i wont be putting another on it. to avoid getting off topic, my real question is

if i do put the HKS SSQV with a stock ECU and i don't leave it as an atmosphecric so ill plumb it back, what are the chances of problems still occuring and how do i prevent them?

thanks for that, can i get some more opinions on this please, as i dont want my car stalling. also what would i do to prevent the "woosh" sound as i dont want attention from the cops? would the sound still come on a HKS SSQV if it was plumbed back?

as everyone has said, you are better off getting a stock replacement bov or a gtr one as they are proven to work. You could probably pick up a second hand gtt bov for like $30-40

thanks for that, but ive already got a HKS SSQV. my question is

when i install my HKS SSQV on a stock R34 with a stock ECU and plumb it back, will i get any problems? and will the blow off sound still be there?

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
