guys,

mine makes a woosh sound as the car revs up, I think it's the
wastegate (not sure) but definately not a BOV!!

How difficult is it to fit a BOV to an R33, and what's a good
BOV for a Skyline??

Fitting a BOV

I have fitted a HKS SQV (Super Sequential Blow Off) to my GTS it took about 15 minutes you just need 1 spanner. The sound is totally different it’s a kind of whoosh and whistle noise, you should be able to notice the difference straight away.

BOV

The stock BOV you don't have one yours is a re-circulating valve. This should be located just before the throttle body on the top of the engine facing to the rear, with a 1½” pipe going in from the right and a thin pipe connecting it to the inlet manifold on the left.
I hope this helps.

Thks Simon,

I'm gonna have a look later:D , would good if you don't need
any major pipework

any recommendations for waht works on a Skyline: I had a TurboXS in my 2nd Pulsar and it was good, but the best BOV I
ever had or have heardwas a Sheepdog BOV that I had in my 1st
Pulsar, I should have kept it!!!!!!!!!

found the stock valve, doh, can't beleive I couldn't find it earlier!!

anyway noticed the way the stock valve is positioned is class!!,
no welding or messing about with T pieces and tubing eh!!

have ordered a Turbosmart Supersonic BOV + adaptor that will bolt straight on:) , plus a Turbosmart boost controller to raise
boost to 1 bar:)

car should absolutely fly & sound the dogs by next week:D

If its dumping to atmosphere you may get stalling at idle, cos the AFM gets confused, might need an add on bit to sort it out.

yeah have heard about that, roughly understand why, but hopefully the BOV i've ordered doesn't do that.

if it does, what do I need to add on??

In theory, any dump to atmo valve on a car with an AFM has the possibility of confusing the ECU. Theory often means nothing in the car tuning world however and most cars with AFMs' don't report any problems at all, at least if using a 'proper' dump valve.

By 'proper' I mean one that won't open on idle. Theres absolutely no way on Gods earth you will open an HKS SQV on idle so thats a good start. This doesn't mean you can't still get problems because you will still be dumping air on the overrun, and in those cases an HKS EIDS (electronic idle stabiliser) is required as Buster says. They are not fitted as a matter of course as relatively few cars show any problems, but it's there if you need it.

I have no idea how the Turbosmart valve works but if it opens on idle or uses some crude method to prevent it doing so, either by using a overly stiff spring/various bleed valve devices or any other air-route method then walk away and just buy a proper valve instead.

Thks Guys,

I think I should be ok, the Turbosmart BOV I chose is real quality,
these guys only specialise in Turbo acessories and have done
so for over 20 years, it's just that thy are based in Oz!!

If you go on the website you get an excellent chart which recommends the most suitable BOV's & associated adaptor & or
fitting kit for your car - superb:D (www.turbosmart.au)

No offence but i've tried a HKS SSQV and whilst it looks great it
doesn't give that nice woosh on throttle lifts. Whilst HKS are one
of the top people for engine internals I do not rate their BOV's, I
think they are over complicated, pricey & overated - just my opinion;)

Sorry pal, must be someone else! We have a customer, with a white R33 GTS-t, goes by the name of Buster and is in his late 40's/early 50's. I saw the text under your avatar and put 2 and 2 together! Whats the odds of that?! He is emigrating to the US soon so thats why I asked.

R33 Type M: No worries. You pays yer money!

Over complicated? Well, I've rarely seen one fail. Also, they are only as complicated as they need to be.

Pricey? It's a relative term. Against £50 'diaphragm' type jobbies they would be I guess...

Over-rated? They do what they say on the tin. Not sure how they could be!

Anyway, like I said it's no problem. Life would be boring if we all did everything the same!

Cheers,

Nathan

Nick / Nathan,

Yip it's always easy to go witha big name, I just know that these
guys have a big following in Oz & so must be good:)

Price wasn't important to me, it cost £160.87 from AET Turbo's,
who are the distributors for the UK, will definately get some
pics and vids of how it sounds when it's all done. It is supposed
to sound awesome!!, we shall see:D

Thks
