Intercooler Piping / BOV
What's the best company to order I/C piping for my stock fmic ? Also, will the Forge bov bolt up to any aftermarket I/C piping or will i need some sort of adapter? thnx for the help

Search around - I like and have the AMS LICP. All UICP are looks not so of the much go (many req. mini batt. -- which does shave weight). The UICP should state what kind of adapters they have or BOV/DVs that can be used. Just go recir, and all will be good.

you must search. PLEASE. this subject pops up like every week and the worst part about it is i've already done an intercooler thread, just not stickied...
damn you ask questions and you have no clue what you're even dealing with. which forge bov??? if it's the one that mimicks the stock mounting (hose type) then it doesn't bolt up to anything, it is clamped by a hose.
several companies make hose type bov intercooler piping. the one that comes to mind first is nisei engineering. http://www.nisei-evo.com/forum/
sit for a bit, read the nisei forum, look at the pictures and see what you're dealing with. then search every question that pops into your head. then read more, then search every question that pops in your head again. keep repeating until you are asking something that no one has discussed before.

Speedfreak0920 (Alex),
In my opinion and as a customer that actually uses a variety of LICP and UICP with stock IC I recommend Buschur and AMS.
Buschur Racing did an excellent job offering an UICP that shaves 19" of piping lenght and also deletes 6 bents, more over it also eliminates two rubber coupling devices and it also increases the diameter of the piping.
Additionally Buschur Racing offers a very competitive aftermarket BOV (1st gen DSM).
I am not sure about how much boost you are planning on running but the 1st gen DSM BOV included on the deluxe UICP package it can hold up to 28psi if you crush it.
AMS offers also great intercooler piping products. I reported a gain of 1.5-2mph trap speed increase when I replaced both intercooler pipes simultanously. Needless to say it also helped my spool up.
I am waiting for my LICP from Buschur, I hope it arrives soon so that I can post the results. Stay tune.
One last tip, definately stay away from intercooler pipes that has multiple pieces.

Maybe it never reached such high boost levels on your car but it certainly does on my car. I gave ride to tons of people on this forum and I showed them multiple times how my car would hold boost very well in the midrange on 4th,5th and 6th gear.
In fact, my number one issue is that I always have to turn down the boost. My turbo boost too fast and too high under normal situations.
I also put my car on the dyno multiple times with Al tuning it and without Al and I reached past 30psi during dyno pulls.
Al Friedman is actually the person that crushed my BOV, he grabbed the wrecnh that he uses to remove the o2 sensor and he placed a whrapped plastic bag in top of the BOV and slammed.. Also, Al Friedman is actually the one that recorded the consistent boost levels on his boost reading devices.
Additionally I have an expensive boost gauge with an electronic DEFI controller that records my boost runs and plays them.
I am not going to argue with you over this issue because each car is different, you might have a faulty BOV. I affirm, confirm and swear that my car holds 28PSI plus no problem during midrange loads in 4th, 5th and 6th gear until the boost starts to vanish rapidly pass 7000rpm.
Remember, each car is built differently, each car has different component and different tuning. I am not braggin over a BOV, I am sharing all the valuable data I always meticulously collect on all my cars and friends car.

actually the fact is that the 1g bovs varied/vary greatly over their production life. there have been stock uncrushed valves that hold up to 18psi and some that will hold nary over 13. so... don't get all hissy guys. the fact is that you're limited in crushing by the upper nipple. why not just not crush and get a leak stop kit?

I know the 1 gen DSM BOV decently well:
I had 3 1st gen DSM turbos cars, and had a 91 Stealth R/T which uses a similar BOV and I now run the one on my Evo 8 and again the stock BOV on my 94 Stealth.
This is no new topic to me. These BOV are tough as S H I T. I know there are much better BOV out there but Hey I am boosting very consistent with the 1st gen one so that is why I am strongly recommending it.
I have two other BOV in my garage that couldn't perform the job. I have a turbo XS RFL-H and the stock and neither could keep up with my mods thus they were ineficient.

Thanks for everything posting and helping me out. I'm getting the Forge RS full recir. bov. I'm going to go with the AMS LICP and leave the stock UICP. I had a crushed 1g bov on my galant vr4 and it worked great for me also. I'm just going go pick up the forge because i know i'm going to want to have it in the future so might as well get it now. thnx again for everyone's help. appreciate it
