Blow Off Valve for 98 eclipse GS-T

[mieszko]

Hi, Im looking for a Blow off valve for my 98 eclipse gs-t. What would you recommend? I was lookign into the Greddy ones.

Welcome to AF

A 1g bov will hold quite a bit of boost for a cheap price.
Problems: Doesn't look bling, won't give you a great bov sound

A Greddy Type-S is also a pretty good piece, for a lot more money. Most like the sound. Holds boost well.
Problems: Expensive

As far as Greddy, there's also an RS. It's not made to be recirculated, and the report from one member said the sound sucked. A few other companies, like HKS, make similar models that sound nifty but aren't made to be recirculated. If you're curious what that means, look in the faq on the front page. If you want sound clips, search for "bov sound clips" or something of the like.

If you'll be attaching a Greddy, or other aftermarket bov, you need to get the appropriate flange for your UICP, or buy a new UICP.

Overall, the idea is to get a bov that does the job (first), and suits your style (second).

I installed a 1st gen bov on my '98 and haven't had a problem with it holding boost. Like Hooptie said, no bling, but it gets the job done. If you check dsmtrader.com you could pick one up pretty cheap.

It depends on what you want

the 1g's have the best bang for the buck

and many others hold nice boost, but the *bling* is what cost ya.

deffinately recommend the 1gen BOV....
Great price...should be able to find an uncrushed one for about $30 and you will also need an adapter to mount it onto your stock UICP if you haven't upgraded it...

I remeber reading somewhere that these cars should have the boost recirculated (spelling?) because if you vent the computer doesn't account for that and it runs bad. Is that true, and if you need to recirculate then it wouldn't make the sound right?

I'd yell at you to search, but you're on the money You even spelled recirc right. Yay.

The ECU accounts for the air that passes through the BOV and adjusts the fuel trims to account for that addition of air in the intake. When it doesn't come, you run rich. This can cause your car to stall. And, when you recirculate like you're supposed to, the sound gets muffled. Some bovs are loud enough for most, at least, even when recirc'd. The Greddy Type-S is an example. Some choose to run their bov vented (non-recirc) because they're ricers, or simply have no problems. A few prominent members on this board vent after tightening the Type-S screw fully, and are good to go. The real solution to venting and not running rich is running an MAFt setup. See Jake's sig. This costs money, and is only necessary from a performance standpoint, after you see a certain (large) amount of airflow.

The 1g and Type-S are the money.

Edit>> OT: Any story behind your sig, drew?

this is true...venting causes your car to run rich. meaning too much fuel for what amount of air is actually entering. the air that escapes when venting is such a small amount that it really doesn't matter a whole lot. might get a backfire every now and then but not often. as for the different bov's...1g's are good, and i've heared quite a few of them vented and they actually sound good. greddy is good from what i've heared/read. it can be vented or recirculated. sounds good too...the hks ssqv is the best IMO besides something like a tial. the hks can be vented or recirculated if you buy the kit (or make your own kit like i did lol). i love the sound of the hks. it has a very unique sound. more high-pithced than other bov's. turboXS's are garbage IMO. they are cheap but i heared they easily go bad. and they are a bitch to adjust. the RFL sounds pretty cool though. either way, they all do the same thing. some do it better and some sound better....it's all in what you want. i have the hks and love it. will never go with anything else....i'll try and get a sound file or two later of my car.

thanks all for the comments. Well i want something that makes a nice blow off sound.

time to look at those bov soudn clips

1g bov makes a nice crisp sound, not loud but better then the plastic sound. Got mine on ebay for 65, then an adapter for 25, both prices include shipping

Combine the 1g bov with an intake and you get a pretty crisp sound. The aftermarket intake doesn't muffle as much as the stock would.
