2nd gen mitsu BOV...any good?

[turbovan89]

OK, I just received a mail order second gen BOV that I thouhgt was to be first gen . Aside from it being uncrushable since it is plastic is it worth keeping? What boost levels can it hold? Should I sell it to recoup my money or keep it? I plan on running 18-20 lbs of boost

Thanks in advance,

Deric

not really. and dont crush the 1g, they tend to wear out and leak.

[krazy4]

get a 1G

[86lance]

people swap out the 2g bov for a 1g

[tkelly27]

yeah, ditch the 2nd gen and mod the 1st gen, not crushing.

[billman]

where is th edifference between them and from what models comes the 1 gen?

[86lance]

any older mitsubishi eclipse or talon or plymouth laser....turbo of course.....and the diff between the 1g and 2g bov is the 1g is all metal construction and the 2g is cheapo plastic.

Can someone provide me the pipe dimentions for this BOV. I want to use it maybe in my Audi. Now i have the stock one and it holds the 1.8 Bar overboost for some years now but improvement is always welcome.

Funny, I was just wondering if it was possible to use some sort of vacuum control to get the bov to hold more boost. I also picked up a used 1st gen and in comparing the two notice that the 2nd gen seemed to be harder to open w/o a vacuum source on the diaphram. That got me to thinking that if a person controlled the vac pressure the characteristics of the BOV would change (much like when we do it to a wastegate). Thanks for the tip cjmr34

ID of pipes are 30mm, OD is 34mm, the Mitsubishi part number is MR188465, Md160689 is the Eagle part number. Hope this helps.
