I want a BOV! which one to buy though? greddy, hks, apex? give me suggestions and any website links you have to them. rx7.com doesnt sell hks.



also, what about boost controllers? do i have any need for one. manual or digital?

first off do you have a turbo charged car? https://www.nopistons.com/forums/pub...IR#>/dunno.gif

You don't need one.

87 turbo II, car specs listed below



dont need which one, boost control or BOV?

fi you got the money for a blow off valve go for it. The greddy Type S is a nice kit, and installs quickly. Great sounds too. Profec-B all the way.

i think the hks ss bov sounds the best, its sitting in a box in my workshop. https://www.nopistons.com/forums/pub...#>/biggrin.png

If you don't wanna spend $$ put a stock eclipse one they sound nice. But if you got flow go for HKS

The HKS SS sounds really nice...and so does the TurboXS RFL-very loud and cheaper then the SS. Personally, I'm going w/ either GReddy or APEXi...I sold my TurboXS and feel like changing now, lol...

hks is great. i love em.

I'm using the Blitz BOV. I love the sound of it.

Ive always been anxious to hear the Blitz bov. Iluvmy88cabrio, do you have the old super sound or the new dual drive bov? Got any vids of how it sounds?

I've got the DD BOV. I was running 13 psi and it sounded great, now I'm only running 7, but it still sounds good. Everyone always tells me how good "my car sounds," I just tell them it's the BOV. Sorry, no vids. of it.

yeah, guy from class has an eclipse with the stock BOV, he was suprised mine didnt have one stock. anyway, i was passing by him once in town and his sounded like something broke when he shifted, not a smooth hiss or anything, more of a pop.



anyway, what placed deal the blitz and hks. i know rx7.com carries the greddy and the apex.

You don't have one!!!



You should...I thought all stock rx7s had BOVs...it's called the Charge Relief Valve..it's the little valve between the top of the turbo and the bottom of the stock TMIC...it has a vacum hose running out of it, and another larger hose running back into the rubber intake hose going into the turbo. If you disconnect the hose running back into the rubber intake inlet...and turn the BOV around to face the firewall..it's much much louder :smirk:

Yeah and then your car won't idle from the huge vacuum leak you just gave it.



Buy a boost gauge before you buy a boost controller. Especially if that is your complete mod list.

i have an autometer boost gauge. yeah, i was wondering about that contraption that is between the intercooler and the intake. i figured it might not be a BOV since all the pressure gauge lines run off it.

Man, not Autometer! Hopefully yours reads right but ive never known anyone with a Autometer boost guage that reads correctly. Usually theyre off like a couple psi. Remember, you get what you pay for! Those Autometer guages are like 60 bucks arent they?

it was already on the car when i bought it. when turned off, it read like 1 psi. dont know how accurate it is in a linear fashion. good enough until i get enough money for a dual pod mount and two new gauges.

i like your avatar, nice pic of dual exhaust fire shot. that your car?

Yes sir it is! https://www.nopistons.com/forums/pub...#>/biggrin.png Thanks, I appreciate it. The Racing Beat full exhaust tends to blow flames. Well about that Autometer guage, thats good then because we all know that anything free is badass! This post reminds me that I need to get a blow off valve too!

if i have a "charge relief valve" do i even need a BOV?



$200-300 is a lot for a cool sound.

You dont "need" a bov. The only time you will need a aftermarket bov is when you are running a bigger turbo. If your staying with the stock one, you should be fine with the stock relief valve.

ok, so i have determined that i dont need a new BOV and the stock bypass valve will suffice. however, i do like the intimidating sound of an ungraded BOV, any way i can make mine louder, possibly have it discharge into the air and not the intake pipe, and still be just as functional and reliable?



someone suggested turning it around, but someone else mentioned this would cause a leak.

what the BOC make to the car ??? I have an N/A.. Can I do something with the BOV. ???



Doest this make more power to the car ?



thanx

Non turbos do not have them.
