That is offensive and unjustified. Excuse me for replying to your inquiry and sharing my experiences and providing facts. I will not make that mistake on any inquiry from you in the future. Enjoy your ignorance.

 

I attempted this install and stripped the back bolt of the bov.... I can't believe this happened and don't know how to remove it from such a tight spot ... Do I have to drain coolant before disconnecting hoses to get better access to it ?? Any help is appreciated !

 

I can't tell from the pic, but I'm not sure that is a bolt you need to mess with. For the spring upgrade: move the coolant tank out of the way (single bolt seen from top of car), loosen the hose clamps (2) on the intake tube and push it out of the way, then remove 3 silver socket head cap screws that are horizontal (with the heads facing the drivers side of the car with an Allen wrench. They are slow to get out as they have loctite on them. Disconnect the electrical connector and lift the diverter valve out.

EDIT: I just reread your post and realized what you said, not what I thought I read.... I'm on the mobile version

That back bolt will be difficult to get. You can drain the coolant to remove the tank entirely if you can't push it enough out of the way. You may also try an easy out on the head of the shcs if it is completely destroyed. I doubt you could get needle nose pliers in there but you could try. Ultimately, if you have to drill it out, I would expect a complete turbo removal would be necessary.

No. No it isn't part of what you said. What YOU said is that somehow the upgraded valve spring allows boost to build at lower RPM. What the exact quote you're feeding off says is that it helps your turbo HOLD MORE BOOST BETWEEN SHIFTS. That is FAR different of a claim. It's not proving more boost at lower RPM, it is simply opening and closing more abruptly and holding a tighter seal so there is less boost loss between gears when the recirc. valve is operating.

 

We'll I got bolt off with long nose vice grips but cracked one of the bov plastic bolt surround areas... So now gunna order a new oem unit.... Any reason to get a forge one since I have to replace? Thanks

 

If you're replacing the stock BOV anyway, I believe it's WayMotorWorks that makes an upgraded version with a tougher diaphragm. Look into that.

 

Glad you got it out!

I installed the Alta spring a few weeks ago. It's a slow process to get to all of the screws. I installed my spring in a new valve that I bought from the dealer. Also bought 3 new screws to replace the originals in case I lost one in the process. This is a nice upgrade and it does what it says keeping the boost up making those shifts getting on the highway a lot nicer without loosing power.

 

So the feeling is generally positive on this spring upgrade? Just got my spring the other day, and the price has dropped...A LOT! Should I also be replacing the diaphram in my BOV/recirc valve when I replace the stock spring with the Alta spring? My '11 R56S has 28k on the clock...looking to have it till 200k! I just want a little more...I really hate the turbo drop-off and lag between shifts.

 

Sorry to revive an old thread but I was wondering about the comments that this would NOT help an automatic. I was wondering why this wouldn't, especially in sport mode using the paddle shifter. It seems that it would. The BOV functions the same, does it not?

 

does the spring increase the noise of the OEM BOV? or does it just shut quick to hold better pressure? Thanks

 

The OEM recirc. valve, it isn't a true blow off valve, is pretty quiet all by itself. The spring just holds pressure better.

 

any suggestions on a BOV.... I am new to this and need advice also do alta do a package BOV and CAI????? If yes where cani get it for a R57

 

Need help from the Alta staff!!! I have an 08 S, manual

Yesterday, I finally got around to installing a Forge BOV adapter along with the Alta Spring. Didn't take too long and wasn't so difficult like I imagined.

Upon test drive, it sounded even more profound (I have the Alta intake as well) with the Forge adapter and it felt like I could shift and boost quicker with the spring. BUT... As stated in the instructions, it is making a chirping sound, more so when I shift, not so much when I take my foot off the throttle.

Now when I redo the installation, what do I look out for to resolve the chirping? I did notice the circular black plastic piece's edge was easily chipping off after I twisted it off to reveal the spring. I reinstalled it and it looked fine but again, it's chirping. Could the spring be misaligned with the piston or should I replace that circular black plastic piece ?? Please respond asap as I need to fix this after work, hopefully.

 

I received mine on Saturday morning and with in 30 mins had it installed, I had to unbolting the coolent bottle and move it out of the way enough to reach one of the bolts on the back side of the bov. Make sure you have a long 5mm Allen wrench and it will make installation a lot easier! I have a few other mods done and with this spring it made a very noticeable difference under heavy acceleration.

 

Will this work for auto transmission?
