Maximum noise..

GFB (Go Fast Bits) BOVUS MAXIMUS..

It has twin trumpets and is probably one of the loudest around.

But at 10 psi it may not be the best option.. these are mainly used on ABOVE 15psi applications. They cost about $320.

I had a GFB Mach 1 on my old RS turbo liberty and it was pretty loud.. they cost about $270 new.

Check here..

GFB SITE...

You could also go for Turbo smart but I am not a big fan of those.. they are over priced and not the best quality in my opinion..

Obivously you could spend more and go for a JAP brand like BLITZ but they are going to cost more than you are willing to pay.

Here are some pics of the GFB Bovs..

GFB BOVUS MAXIMUS

PLEASE NOTE: with these atmo venting valves, your car will start to back fire and run rich and sometimes stall because your car has a air flow meter like all the other skylines..

GFB also make a HYBRID BOV which vents some back to the inlet like the stock bov and vents the rest to atmoshpere making the psshh sound..

These cost about $330.

here is a pic of the GFB HYBRID BOV..

ANOTHER NOTE: You will get defected and FINED with any ATMO venting BOV if the police check.

see ya..

when i was running 10 psi on my 33, i hooked up a second hand but nearly new Turbosmart Type 3 (so called "supersonic") This is said to be one of the loudest around. Even at 10psi it was still nice and loud. They often come up in the trader. Mine cost 200 bucks.

I thought the quality was fine, and they look tough, with a nice fat trumpet. I found that just going up to 12psi makes the thing sound crazy!

There is one for sale in the classifieds forum, as new, for only 280 bucks.. If i were you id buy that. Its also the current shape Anodised housing, they look real nice :uh-huh:

im running a bovus maximus and yeah like GTST says my car also runs rich and stalls particularly after coming off boost and slowing to a stop. other than that, the sound is really nice and when i drive past bus stops, the chicks always look.

-----------------------

Any BOV that vents to atmosphere will potentially cause the car to stall coming off boost (its very annoying, when i put my type 3 on, i simply turned up the spring tension and it cured it, as a negative though, it made the BOV quieter at lower boosts, as the spring was now too tight). This is coz they are AFM equipped.

-When you boost up "x" amount of air is sucked passed the AFM, and the computer supply's "x" amount of fuel for that air.

-but when you back off, most of that air is released from the inlet tract, and never makes it to the manifold to mix with the extra fuel provided. The result is a state of temporary richness as the car comes down to idle, which causes the stalling.

Therefore:- vent to atmo BOV's confuse the AFM and stock ECU.

I feel the need to state these facts as it took me time and frustration to figure it out, being new to the turbo game.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
