bypass valve conversion q...

11-10-2009, 04:58 PM
has anyone tried to make the stock bypass valve vent to air? i was thinking if i blocked off the air intake return side and put a one way check valve on the out port of the bypass valve would i be able to hear it? if this not a good idea someone please tell me...but id rather try this to see if it works then to spend the $125 for a BOV. it should work if you think about it, its still going to let the compressed air out, just to the atmosphere instead of back into the intake. just a thought :evillol:

The stock system is set up to recirculate because of the MAS set up. Don't vent to atmosphere or you could cause driveability problems or possibly stalling.

ahh, bummer. i never thought about that. so does anyone make a recirculating bypass valve that you can hear? and if someone does, do you know which one is the loudest?

Ive got a Greddy RS recirculating...I like it. Not loud enough to be annoying, but you can definitely hear it.
Theres recirculating kits for alot of the popular BOVs.

greddy type-s knock offs. you can get them on e-bay for like $50

cool. how long do you think that knock off would last? or should i just suck it up and go with the greddy? and for the y pipe, can i hook these up to the stock one or do i have to buy the "bling bling" chrome one to make it work? i would rather keep the stock one instead of having 1 shiny thing in the engine bay. also, im not boosting enough to pop the stock one off, so id like to save as much money as i can so that when something breaks, i can afford it :iceslolan and thank you everyone for answering all my questions. hopefully one of these days i will be able to answer some other newbie's q's lol

they're made at the same place that greddy had them produced... they just don't have a greddy sticker. it's all the exact same shit

I beleive thats incorrect Emilie. They are Chinese knock offs that were reverse engineered. The early knock off versions were said to be well made, but the newer ones are said to have a failure rate.

the BOV is actually mounted on the intake "bubble", and connected to the y-pipe through a hose.
Buy anyways, the stock y-pipe should work fine.

if you look hard enough you can find a used REAL one for not much more than that...i picked mine up for 75.

alright, ill keep a look out for all of them. i had another question that ive been trying to find but havent come across anything yet and id rather not start a new thread. i have a friend with a layth (sp) and i was wondering if i could drill out the lifters to 3mm? does the stock 1mm stay that same width all the way through? im not planning on trying this until spring but i thought id get some info on them. thanks

No, it won't work.

You can seriously buy all 24 lifters for around $100 if you look hard enough.

11-13-2009, 11:13 PM
i htink there's still a group buy for like $112 going on...

11-14-2009, 07:28 PM
really! the cheapest ive found is like $530!! which is the reason i asked about drilling them lol...but ill keep on lookin :). thanks!!

11-15-2009, 06:23 AM
damn 530? maybe that's for a set of heads w/3g lifters? lol
seriously im pretty sure that's more that dealer MSRP...you must be confused
