Buying Injen Intake HELP!-Concerning BOV....

[Zmann42087]

I have a 97 GST.... all stock minus a Weapon R cone-shape performance air filter...or in other words all stock! Anyway, I am going to buy a Injen short ram intake. They have one for cars with stock BOV's and ones with aftermarket BOV's. I have a stock BOV so I would, obviously, purchase the one for stock BOV's. My fear is that I am going to buy the intake for stock BOV's and find out I want to replace my stock BOV for an aftermarket one. With that in mind, I want to replace my BOV before I buy this intake.

My Questions.....

Should I replace my stock BOV? I think I should.

My most important question! ---> If yes, than what is the best replacement BOV for 2G's?

Also should note that after the new intake, I am going to buy a Greddy boost controller and upping the boost, so please keep that in mind when suggesting a new BOV for me!

Does the Intake for the aftermarket BOV still have the recirculation inlet? They didn't have an option like that when I bought mine, and I ran it with the stock bov and the greddy type s. As long as you have the inlet for the recirc tube you will be fine. Unless they changed something that I am not aware of

 

[DSMSpyder99]

yea when i bought mine it didnt have that option stock BOV or aftermarket. All i asked when i ordered mine was if if had the BOV return inlet. They said yes and it worked great with my stock, Type-S, and soon Type-RS (just got my recirculation adaptor today)

Go ahead and get the intake that is for the stock BOV. You do not want to vent your BOV to the atmosphere. The OEM 2G BOV's are plastic and are known to leak over time. As a cheap upgrade, I would recommend using a 1G BOV (it is metal, and functions quite nice). Or you could get something aftermarket and more expensive along the lines of a GReddy Type-S. Both will work great with that intake though.

The intake that says it's for a stock BOV has the provision to recirculate the vented air.
The intake for an aftermarket BOV must vent to atmosphere, as it has to recirculation tube.

 

[Bigglesworth87]

When I ordered mine I didn't have an option either. Could you show us a link to see what they are offering?? As far as the BOV is concerned to go a cheap route get the 1st gen bov but make sure you get the upgraded intercooler piping so you don't waste money on a flange to hook up to stock piping.

 

[killakev805]

It depends on whether you are going to vent to the atmosphere or not. I made the mistake of buying the one for aftermarket BOV because I knew I would be upgrading, but it doesn't come with the inlet for the venting. So I had to buy another one for the stock BOV . It doesn't matter if you change your BOV if you to vent back to the intake; get the one for stock BOV.

If you decide to go the other route and vent to the atmosphere I have one with a k&n filter. PM me if your interested.

As far as a BOV I agree with 99GST Racer, I have the 1g BOV it works great, and you can pick one up for cheap.

 

[Zmann42087]

Is that Greddy Type-S valve you guys mention a diverter valve? In other words, does it have the connection to recirculate the air? I may not understand BOV's right, but if you don't recirculate the air, don't MAF's (Mass Airflow Vehicles) get a false signal? Ughhh... This is new to me, so I don't know if I understand it right. A little help please...

U got to get a sound bite of that!! thats the one I'm going to

I'm also getting an Injen intake, the only options are with the bov tube and with out...

Yes, the Type-S is a true diverter valve just like the stock 1G and 2G came with. It is made to be recirculated, and that is why I recommend using it as an aftermarket alternative to either of the stock valves. If your MAS is before the BOV, then you cannot vent to atmosphere. If the MAS is after the BOV, then venting is OK. A diverter valve is the same thing as a recirculated BOV.

OK, I have looked at the Greddy ad in my Super Street Mag and been on Greddy's website, is the "Greddy Type-RS BOV" the same thing as the "Greddy Type-S BOV" you are talking about?

 

[Bigglesworth87]

It works the same but its an updated version of it and sounds different. Both will work fine with your application. Go to google and type in an image search GREDDY TYPE S, and then run another search and type GREDDY TYPE RS. You will see the difference.

 

[Pezking]

Isn't there a BOV using dual chamber technology that recirculates ?

Oh wait, there is, but I mean other than the HKS SSQV...

 

[Zmann42087]

Never mind my last post! I found what I was looking for on Greddy's website. It answered my question. One more question... Those of you who have the Greddy Type-S BOV on your Eclipse, did you guys buy the kit made specifically for the Eclipse, or did you just buy the BOV?

 

[Bigglesworth87]

Dont buy the kit, save yourself the 30 bucks and get the upper intercooler pipe that is flanged for the bov.

Did your suggested Google search. That helped a lot! Like I said in my last post the Greddy Type-S BOV comes in a Eclipse specific kit, does the "newer model" Type-RS come in a Eclipse specific kit as well?

Keep in mind that the old GReddy Type-S is a diverter valve. The newer Type-RS is a BOV. It requires a special attachment to recirculate air back into the intake (making it a diverter).

That kit you are asking about, is to fit the Greddy valve onto the stock upper intercooler pipe. I would recommend getting the GReddy upper IC pipe kit at the same time as the valve; that is if you can afford it. The BOV will bolt right to the GReddy pipe, and you will not need the kit in that case. But if you plan to run the BOV with the stock IC pipe, then you will need the kit.

 

[tonygst]

if you are not replacing the Upper intercooler pipe then you have to buy the kit that has an adapter to fit on stock intercooler piping.

You can buy upperintercooler piping that is flanged for the greddy type s for $210. That also comes with lower intercooler piping.

 

[99gst_racer]

OK, this is a total newbe question but, which pipe is the upper intercooler pipe?

hah, thats what the NewB section is for. The upper IC pipe is the one that runs from the intercooler to the throttle body. The lower IC pipe runs from the intercooler to the turbo.

 

[Zmann42087]

OK, now I know which one it is thanks!

So where can I get the upper pipe that will fit the Greddy Type-RS BOV?

Tony mentioned that I could buy a kit that would fit the BOV for $210 and it would come with the upper and lower piping, but he didn't say where.

Does it have to be Greddy brand piping to fit? I ask because I found a Dejon upper intercooler pipe for sale on ebay for $40. Could anybody tell me if it will fit the Type-RS BOV?

It does not have to be greddy brand intercooler pipes but it has to be flanged for the greddy type s bov. The ebay link you posted has a Tial BOV flange.

 

[Zmann42087]

Sweet! Thanks for all your help "Mr. Bigglesworth". Believe it or not, I don't have any more questions! Hang around, I'll let you know how I came out on the auction.

 

[Zmann42087]

YES, $45 wins me a Dejon Upper intercooler pipe!

Man, I love Ebay!

 

[Bigglesworth87]

Ummmm.....I have a little problem with your auction. 1) It says its flanged for the Tial BOV, and you were clearly talking about the Greddy BOV, so your going with a Tial BOV now? 2) It also states that the pipe is to be used for a GM MAF, which you don't have now and will cost you more then what you think. Am I reading this correctly or am I just too tired from work and not seeing it right?

If it is what I think it is, then you have wasted your money on something. Please let us know.

 

[White97eclipse]

Isnt the Tial BOV better than the Greddy? Speaking of the Greddy.. how much boost can it handle?

A little off the subject of Greddy but... what is the dif between the crushed 1gen and the regular 1 gen and where is the cheapest place to get one? sorry, not trying to steal the thread, i just thought it would add to the knowlege of BOVs in this post

Yeah Mike, you're correct. That UICP is for a TIAL BOV ONLY and cannot be used with a GReddy BOV. It is also made to run a GM MAFT in the blow-thru set-up.

Zmann42087 - You got a very, very good deal on that pipe, but it will not work for you. You need something like THIS.

Isnt the Tial BOV better than the Greddy? Speaking of the Greddy.. how much boost can it handle?

Yes and No. The valve on the Tial is larger, so it is more efficient in a high boost application. But the Tial is a BOV only (not a diverter). It cannot recirculate the air back into the intake tract. It is a great BOV for the MAFT blow-thru set-up, but the TIAL BOV is denititely not something the thread starter would be interested in.

Crushing the top of the 1G BOV causes the internal spring to compress, basically allowing you to run higher boost w/o the fear of the BOV opening under load. Cheapest way is to crush your own on a vise. But if you dont know what you are doing, then I wouldn't recommend doing it yourself. Overcrushing it will ruin it.
