I am about to drop in my evo 3 16g and dejon fmic kit very soon. I was looking at all my parts before and I realized that the dejon fmic lower piping doesn't have a nippile on it for an mbc.. since the evo3 doesn't have a nipple on the compressor housing, where am I going to tap into for compression when I put the turbo and fmic on?? :confused:
 
You can put a custom nipple on the LICP. You could put the nipple on the compressor-side of the turbo, but the former will probably be easier. Take it to a shop and have it done. Shouldn't cost very much at all.



EDIT: You can see what I am talking about in the link below (look at the first picture in the post):

I wouldn't even know how to do that.. shouldn't the pipes have come with a nipple.. where do they expect you to tap into?
 
I emailed Dejon Tool and go this reply:



You can "T" into the line from IM to BOV or install a nipple somewhere.

No, it does not sound alright.

Do not tap into your BOV line. Utilize the first link I gave you. Tapping into the BOV vaccum hose is the "old" way of thinking, and it happens to be the wrong way. "Dave" simply gave you bad information.

I agree. The J-pipes that vendors sell should come with a nipple, but they do not. I am more surprised that the EVOIII16G does not come with a compressor-side nipple. But now you have to work with you you've got. So take the pipe to a shop and have it done, like I said in my first post.
 
I remember reading somewhere that you could also use one of the nipples on the throttlebody if you've already removed the emission lines.

Truthfully - it doesn’t matter where you tap your MBC. I would like to know why you think this is the 'old' way of thinking? Personally, I get more consistent boost pressure and what seems like faster spool-up when taping into the manifold. Now given with a front mount you WILL experience a higher pressure drop than on a factory setup - I would think you would want your MBC at the manifold rather than at the 'j' pipe.

The only down side to taping into the manifold that I can see is that if one of your IC pipes came or had a significant leak you could potentially grenade your turbo due to over spool because the WG wouldnt open.

Yes. It does. Maybe you didn't read through the first link I gave. If you didn't, please do so now.

If you would like to know more information about why mostly everyone concurs with brute's write-up (that is, the author of the first link I posted) then use the search button and then click, read, and scroll, click, read, and scroll, click, read, and scroll until you get blisters.

Don't get me wrong here - I understand the warnings / potential dangers of incorrectly installing a boost controller and I agree with Brute's statements. I am simply offering another alternative to mnetworks's dilemma. Let me put it this way - if you are so scared that something bad will happen (1 in 100,000 chance) by installing your MBC at the manifold then simply don't do it. Better yet we might as well all sell our cars and walk to work because driving nowa days is too risky!

The main reason I decided to tap my MBC at the manifold was because I was sick and tired of it clogging from the Oil buildup coming from the 'puke tube' on the rocker cover. Granted this was before I installed a catch can. Who knows, maybe someday I will put it back. Its just nice to have options.

I was looking at the box that my Hallman Pro RX MBC came in.. and along with the heavy spring and the t-fitting it came with a nipple. Is this meant to be installed on a pipe? It is threaded and everything.. what would be the best way to install this on my j-pipe and make it leak free??
 
mnetwork - You basically have three options:

1: Take your j-pipe to a welder and have them weld the nipple that came with your MBC to a convenient location on your j-pipe. - This may be your best option given your setup and shouldnt cost much.

2: DIY: Find a nut that with thread on the nipple that came with your MBC. Drill a hole in your j-pipe and using Teflon tape and or other type of sealant secure your nipple in the hole you just drilled using the nut and hope it doesn't leak - this route may be difficult if the surface is round.

Or as I have stated and for the time being:

3: Tap your MBC into the intake manifold. - Easiest way to get you up and running for now.

Just be careful if you decide on going th DIY way - you dont want to f-up your new pipes ;-)

I hope this information helps you in getting your parts installed sooner than later. Remember, you can always go with option 3 for the time being then down the road have someone weld a nipple to your j-pipe or as close to the turbo as you fancy.

Yeah, that sounds like the options... Dejon Tool said I could just dril and tap a thread to match the one on the nipple and screw it in.. That is probably what I'll do, either that or bring it to a welder..

I wouldn't even know who to go to, to have it welded though..
 
This is so old.. but I just wanted to update..

I just sent the j-pipe back to Dejon Tool and had them add a nipple on for a few bucks.. problem solved..
