every now and again i would pull up to a turbo n i hear the BOV go crazy...

"tu tu tu tu tu tu..." lol

i was just wondering if i could do something to my stock BOV on my 32 to make it flutter aswell...

if it can be done, can i please get a quick run down on how to do it...

thanks guys, Michael

Yes it can be done. And no it is NOT the blow off valve making this noise. Ite the noise u get when your bov is BLOCKED or REMOVED.

WHen your car builds up boost and you let go of the accelerator. The pressured air in the system has nowhere to go because your throttle body is closed. Hence the blow off valve vents this pressure. If you have a REMOVED or BLOCKED blow off valve the air will go back through your turbo and out to where your air filter is. The Tututu noise is the turbine wheel "chopping" the air to make that noise.

Best way to do it is to removove the BOV, get an inprint on somtehing of the flange. Get a coke can and cut it open. Cut the coke can into the same size as the flange. THen put the new coke can gasket inbetween your piping and the blow off valve. This pretty much blockes air from going to your bov. You will then get mad VL flutters y0 tu tu tu.

Oooooorrrr you could squash the crap out of your stocker. It will still vent and plumb-back but it will cause your turbo to make the flutter sound when you back off the throttle lightly when on boost. It will vent normally but quicker than usual on sudden throttle lift off....eg. gear changes.

lolz i made a block for my mates gtt with some mdf, a rubber gasket, a drill for the holes and jigsaw to cut the shape lolz.

worked a charm but your idea is soooooo much better; why didnt i think of that

God not this shit again...

Why does this get brought up every week.

Speaking of flutter/dose, has any one seen that ignition dvd with the BADWOG R33 (its a pretty old one) and he goes on about wanting the car to flutter?

F**k its piss funny!!

"I wanted a hektik flutter, like a full melbourne spec VL flutter! Its bad for the turbo and its probably gonna blow but its hektik!"

Hahahahaha god that was gold!

God not this shit again...

FLUTTERZ BIBLE

Must be school holidays....

Thats because those people are nobs who want to wreck their turbos. If you want your turbos life to be drastically reduced, get a pod filter and block off the BOV.

Or you could just get the word nob tattooed on you your forehead as this has the same affect.

    • Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in
    • What do you mean by "seals"? Internal hydraulic seals (ie, is it leaking PS fluid?) or the rack boots that close the rack onto the tie-rods? Because the former is a rebuild, and the latter is trivial that you or any nearby mechanic could do. Dunno about the cowl. Just buy what you think is required and get anything else you find/break afterwards. Wing? Dunno. Don't like R33s enough to pay attention to them. Mirror glass is just glass (on the surface that you want to polish). Go for it.
    • Hello! Long time lurker, been using the forums to address concerns and questions from afar for a while but I've struggled to find some answers so I guess its about time I made an account and formally asked some more knowledgeable people, since finding local skyline owners is hard (and shops that are knowledgeable or trustworthy to work on 'rare' cars are non existent out where im at, as skylines are quite uncommon to find in the wild around here). So the main 3 questions I have, 1: Steering rack has blown seals, well.. they kind of hold but they are not sealed properly anymore and as my R33 is my DD, i cant exactly rip the rack out and send it off or attempt to fix myself. As most refurb ones are around $1,100 or more shipped, and I have other things I need to work on around the car, I was seeking clarification on whether an S15 rack will more or less bolt right in, and whether a common mechanic could do any other required work to get it to fit. I ask, as I've found a supplier than can sell a manufactured as oem one for around 400, if not I'll likely order a used one from Jacks JDM, and take a risk on the seals there. The second question i have is that im replacing the front wiper cowl and have planned to buy 4 new clips and a new center clip but wasnt sure if there were any other clips that would also need to get replaced while I was at it. Given im sure any that are there now will simply break when I remove the old cowl... Last thing would be a fairly straight forward question, i think. If I manage (strong if, finding one has proven to be a pain) to find a R33 GTR spoiler/wing will it require much modification to bolt to a S2 R33 GTST? I've read the bolt patterns dont match but otherwise would bolt in, only options I have found with much luck is China stuff on ebay and carbonetics, which has a nice $650 shipping fee... so if anyone has any pointers where a US chap could locate one that would be great Random side question as well, the mirrors as I understand are mirror glass, and as im planning to polish my windows from water spots and surface scratches, i was hopeful cerium oxide would be fine for them too, as my research points to, but clarification is always nice. Any pointers would be appreciated, and while I have scoured the internet for answers if I missed a prior post somewhere that may answer these directly please point me towards it, as i must have simply missed it. I have seen a post here or there that has mentioned it, but I usually get 50-50 answers, or half answers... I dont have a lot of fab experience or mechanic experience, outside of hydraulic and pneumatic stuff I did in the military and with how hard it is to source stuff in the US, id rather not wing it and hemmoraghe money lol. Thanks guys! Sorry for the monumental first post haha
    • Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
    • Got you mate. Check your email!
