View Full Version : 1g DSM BOV questions!

So I was thinking recently that to save myself headache in the long run with the plastic BOV on the evo I would replace it either with a crushed 1g BOV or the one from my old Nissan's turbo kit which seems to be identical to a 1g DSM BOV. I'm thinking of doing this for reliability reasons since I'm thinking the plastic BOV might not last long after modding the car and I would rather take care of things (cheaply) like that right now since I already have one sitting in my garage or can pick one up from a friend.

I searched on here about 1g BOV's but found nothing and I searched on Evom but feel kind of wary about some of the info on there. So can anyone help me out with these questions I have?

1. Is a 1g BOV a good upgrade over the stock one?
2. Will it bolt right up to the stock intake piping?
3. Any insight you can give me is very much appreciated.

Get the 'JDM' BOV: it's metal. I think it also comes on the IX's since that's what my MR has.

Exactly
The JDM Evo's came with the metal BOV that is now standard on all IX's.

I thought the 05's came with the metal too? Or was it just the MR's?

None of the 05's did.

That was my original plan but why spend over $100 plus shipping for that piece when I can just go get a 1g BOV for $20 tomorrow from a friend?

Are there are any advantages to getting an MR BOV over a 1g BOV. If so I would gladly get the MR. If the advantages of the MR over the 1g BOV don't make up for the price I would pay then it would not seem to smart of me to go and get it.

Can you tell me why I would get the MR over 1g? Any help is appreciated!

the metal "MR" bov will hold more boost than a 1g bov without crushing the 1g bov. You would also need an adapter as the MR bov has the tubing attachment where the 1g bov has a flat bottom designed to bolt directly onto a intercooler pipe.

If the 1g I'm looking at is already crushed and I can get an adapter from DejonTool for around $30 is it then comparable to the MR in terms of holding boost?

Sorry if my questions are getting annoying I just want to be able to have solid factual information for myself and for other people to search on here and find it.

Sure, you just need to make sure it was crushed correctly.
