ditching the greddy RS bov, will anything else fit? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

niSm095 · 10-04-2007, 06:16 PM

I'm having problems with my greddy rs bov, so I was going to ditch it in favor of something else...does anything else fit on the greddy flange other than the greddy bovs? or will I need a new hotpipe?

smelly240 · 10-04-2007, 06:23 PM

whats wrong with it? I never had problems with any of my greddy bovs.

i did have 2 leaky HKS ones tho - a SSQV that leaked outta the bolt hole (first ssqv when they had adjusters) and a old ass super bov that leaked

is it not opening? leaking?

I had to turn the knob in on my old type S so it didnt leak at idle... the rs is kinda in - not as far tho.

niSm095 · 10-04-2007, 06:32 PM

I've messed with adjusting it open, and it doesn't seem to be doing anything...all I hear shifting (low and high rpms) is verying degrees of compressor surge.

SHIFT_*grind* · 10-04-2007, 07:14 PM

I'll be experimenting with coercing a 1G DSM BOV onto a GReddy RS flange in the next week, I'll keep you updated on how it goes

Lucient · 10-04-2007, 07:43 PM

I actually got my HKS to fit a greddy flange by carefully drilling holes into it. Just use the gasket as a template and drill the holes. Mine has never leaked either

smelly240 · 10-04-2007, 08:22 PM

1g dsm bov you MUST recirc! It will be open at idle...

Sounds to me like you dont have the vacuum line hooked to the right place (or not to a proper vac source.

+1

i had a similar problem. part of it was due to a few small vacuum leak, the compressor surge was just a matter of tuning the bov's tension so it stays shut just enough under boost, and soft enough that it'll blow off on low boost. just experiment with it a little...see how it goes. good luck

niSm095 · 10-04-2007, 10:39 PM

I looked for vacuum leaks, couldn't find anything. I've adjusted the tension a little, it seems to have helped some. Couldn't get on it though tonight, roads were wet. I'll try it tomorrow and get back to you guys.

HKS Racing bypass fits, I used one on my old car that was made for a greddy bov.

do you have both springs in? When I first got mines, it had both the hard spring and the soft spring in... it didn't matter how I adjusted it, it was just too stiff.. so I took 1 spring out, and now it opens perfectly

smelly240 · 10-05-2007, 04:13 AM

also - where are you taking your vac source from?

niSm095 · 10-05-2007, 05:05 AM

thats odd...why would they give it to you with both springs in it already?

I believe the vacuum is coming from post throttle body, i'll check this morning

Koopa Troopa · 10-05-2007, 06:23 AM

Greddy Type R. Don't waste your time with anything else.

Bad40r7 · 10-05-2007, 08:58 AM

The greddy Type R is way to stiff and big for a small turbo small boost application. That bov is meant for 15+psi atleast

if you tighten an RS all the way, the valve DOES NOT OPEN.

unless you switch to MAP or Blow-through, you really should recirculate your bov. It will increase your drivability ten-fold.

If you insist on venting to atmosphere like every other ricer who thinks he's fortunate, at least get a TIAL.

Type-R = Winner

what an idiotic statement.

anyway...

I have a 2871r running 12psi right now, plan on tuning to run 15-18 psi. I found a great price on a blitz bov...I'm thinking of going with that.

if not I may try to type-r

Cool BOV. Dunno if it fits though. =P

niSm095 · 10-05-2007, 08:07 PM

to me it looks like an HKS blow off valve with a valve like the greddy instead of a diaphragm like the hks

niSm095 · 10-05-2007, 08:08 PM

any other ideas? I tried to pull the spring out like you said, there was only one spring in there already. I bought it used, so it's possible one was removed.

SoguRacing · 11-29-2007, 02:38 AM

I would recommend the Synapse bov, it supposed to eliminate compressor surge and you you can buy different mounting flanges for it. ie, the greddy mounting flange. bought mine for about 220 bucks and the flange adapter for about 20 bucks on www.enjukuracing.com. works for me had for about 2 weeks cuz the greddy one sucked balls. tried the single spring mod and still no luck. also remember to reroute the recirculation valve back into the intake piping. good luck

Isn't that the goal of all blow off valves?

jspaeth · 11-29-2007, 08:49 AM

I have a Greddy Type RS, and when it works, it works very well.....every few months, the diaphragm will get stuck and pinch, not allowing it to close all the way, but then i just open it up and put some grease on the diaphragm lip
