HKS bov install 97 gst

[l3igl3ang]

ok i got the hks and got a flange order what all would i need to install this on my gs-t. also how do you by pass the pipe that connects to the dumb tube do i just block it off ? cause the bov has no way to connect that pipe to it and also is there a picture guide on howto install them step by step like the greedy bovs.

Unless you have the MAFT set-up, you aren't going to want to run the system bypassing the dump tube. It is air your engine is counting on being there. There are tons of forums on why that is not a good idea.

Do you mean the intake pipe which runs from the MAT to the inlet on the turbo. If so you can get a Recirculation kit or cap the intake tube and vent it which is not a great idea. Then if you have the flange you will need to weld it to your inter cooler pipe and if you don't have hard pipe you may need to get some other wise get the kit from HKS that attach's the bov to your stock pipes. Good luck man if there is any thing else you need let us know.

o sounds like a lot of work i guess i will stick to useing my greddy on

 

[larsenracing]

It will only take about 5 minuets to do it and its pretty self explanatory.

I also have a 97 Gst and i also have the HKS SSQBOV. I bought mine from stillen and when it came it had a machined aluminum cap for the factory intake tube. It fit like a charm. Ok so now for the "don't vent your BOV to the atmosphere" part, well i have read all the forums and posts about it and it is a valid argument because the factory settings in your ecu are accounting for the returned air from the bov, however, it is a nominal amount of air, which may or may not affect performance depending on many different variables such as engine wear, compression, and general engine condition. What i'm saying is that it may or may not cause you problems. I have had mine venting to the atmosphere since i've had it installed and have had no need for the recirculation kit at all. That may not be the case for you but the only way to actually tell if it is necessary is to try it.***** I have no absolute knowledge if it will or will not harm your engine****** so i will not say that it won't just to cover my ass, but in my strongest opinion it will not hurt it. Maybe some can elaborate on the effects of the missing air in the ECU equation? Anyway once you install it and have it runnning you will find out if you need the HKS recirqulation kit, which is not hard to install at all. If you have any other questions related to the install i'd be happy to help you.

I have my ssqv venting to and I personally don't notice any problems but some do and some don't. But I don't have a dsmlink either so i cannot prove better or worse but you probably would be better off recirculation it just from the arguments that I have read. Personally if I had an intake that had a nipple on it and i drove the car more i would probably recurc it or more than likely just spend the money and go with a GM blow threw set up.

This is absolutely incorrect, and you shouldn't give bad information to people who are trying to learn.

The fact of the matter is, you are venting metered airflow- what that means is that the ECU is seeing more air than it is actually getting, so the car goes stupidly rich. If you do really hard fast shifts @ full boost while vented on a stock MAF the car will actually STALL OUT. Oh yeah, and that's with an SSQV. The only good thing about venting on the SSQV on a stock maf while venting is that it doesn't leak air at idle.

FACT: Unless you have a MAF-T, MAFT-Pro, HKS VPC, AEM, Haltech, Autotronic, MS, etc and you are venting, your car is NOT running well. Converting to a MAF-T or speed density is the ONLY solution that allows the car to run properly while venting, and frankly is unecessary unless you need an incredibly strong BOV like the TiAl 50mm that is not able to be recirculated.

ok well thanks for your reply bud, but you just verified my point, so i'm pretty sure that what i said is "absolutly incorrect". No big deal though. Due to the fact that the ecu is programmed with a f/a map based on multiple sensors in and around the engine it is telling the fuel system that it is recieving said amount of air at certain times, aka fuel map, but the thing is that this air from the bov is only vented at certain times. And once again depending on the condition of other components in your engine it may or may not be a noticeable change. Yes the easy answer is it will make your car run rich b/c of the pre-programmed ecu, but only the mitsubishi engineers or someone with the exact knowledge of the stock architecture would know what the ultimate values are at each given time on a stock setup. and i do agree that there is not a real benefit to venting unless you have a reason, like one of the ones mentioned by slugsgomoo, among others, but that does not mean that your car will stall out under hard fast shifts. This is not a fact. anyway if you cannot find the install instructions let me know and i can email a copy of mine. - chris

 

[l3igl3ang]

i would have to have a guide with pictures to know what to do cause i know almost nothing about turbo cars.

 

[chrisbarz]

i can do that 4 u if u need it... send me a message with your email and i'll send it to u if you want. let me know - chris

 

[chrisbarz]

and oh yeah i meant to say that what i said was not absolutly incorrect! haha i thought i prrofread it but i didnt see that till after i posted it - whoops

If you wan't I have a recirculation fitting for the HKS SSQV I'll send you for 12$ shipped. Then you don't have to worry about it.

Also, to aid in your install(this is what I did) Unfortunently I cannot remember if the "plastic" piece of the stock tube actually connects to the intercooler, so you may have to buy/find a piece of stock tubing that will fit it. I used a 2.25" pipe that was about 8-9" long and had the flange welded to it in the center, the ends were beaded after fitmet. Anyway, 8-9" pipe (cut to size) with some of the stock like tubing connecting the intercooler, to the 2.25" pipe, just lay the pipe in their sideways, figure out what length it needs to be to slide the stock upper intake hose over the 2.25" piping and clamp it down.

EDIT: with mine setup like this I was even able to use the stock bov outlet return tube.

 

[l3igl3ang]

i got a little baggy with 3 white hose extenders or somthing i thinks its a recirculation kit it has a blue lght as well and a small hose clamp and a rubber washer.

 

[l3igl3ang]

also will this fit on my stock UIPC with a flange? so i can shut the hood and it wont get in the way.

and rowlex do you accept paypal?

 

[l3igl3ang]

ok i found these pics is this all i need to do?

Yes. however it will not fit onto your stock intercooler (plastic) pipe.

I will do paypal as long as u pay their 3% fees.

 

[l3igl3ang]

i got a flange orderd which connects it to the intercooler (plastic) pipe

so what your selling is pretty much same as this one?

and i got one of these orderd

http://cgi.ebay.com/ebaymotors/HKS-...036556827QQcategoryZ33742QQrdZ1QQcmdZViewItem

will the bov still be loud after Recirculating it instead of a blowing it off under the hood?

Yes, the piece I have is exactly like the top link.

The second one says it's for an evo? It looks like it would probably still fit the piping of the 2G tho. I have no idea if it will for sure.

You should however replace the upper intercooler pipe... It is a large restriction point.

O man, enjoy el snap-ring. That thing is a PITA w/o the special tool, .

 

[l3igl3ang]

Yeah that ones to a evo but the eclipse one looks the same. I just used that link cause it was the first one i found and i will surely buy that peice from you so its $12 total plus 3% pp fees which is 36 cents i belive so it would be $12.36 total ?

I guess u can post your paypal email here on pm it i can pay asap i got some money in my account ot cover it

And on the bov theres a little pipe that sticks out the back is this were the sound comes out or do i hook a hose to it?

Sounds good. The nipple on the back needs to be plugged to your intake manifold as that I believe is the reference line that tells your BOV to "release."

I will PM you my paypal address tonight, Need to make sure I know where I put the recirc fitting I will ship it out tommorow, after I receive the notice of payment.

Yeah thats what i was thinking cause my greedy one has a nipple thats unused which i belive the sound comes out of which is the same size so i wanted to make sure first before leaveing it unpluged.

The bov's loud as hell venting. My friend heard it a block away indoors... However, it presents drivability problems especially during highway driving when you let off the acc suddenly. I'm gonna recirculate mine as soon as I get an aftermarket intake.

O man, enjoy el snap-ring. That thing is a PITA w/o the special tool, .

What is this snap-ring i'm hearing about? I'm about to order the HKS BOV w/recirc. and i have no idea what you guys are talking about. I've read the how to on this page:

http://www.dsmtuners.com/forums/showthread.php?p=1082945

but what's c-clip and o-ring everyone's talking about? Anyone got any pics of where it should go? Cause the look of the page didn't mention anything about an o-ring or clip.
