MBC or 3 port ?
Hello again
as the title says MBC or 3 port boost ive got a mbc on at the moment but im not to keen on it id rather just run the 3 port but just need to know where all the pipes go ive had a long search and its all a bit vauge lol also what are the pros and cons of the mbc and the 3 port i just wanna make sure when i can drive again the car is ready to go lol thanks |
MBC works well.
Was a 3 port originally fitted to the car and is it mapped? |

sorry the 3 port is there , the previous owner put the mbc on
and as far as i know its not chipped its a v1 sti import ive been searching the internet for where the pipes go to put the 3 port back on but getting a headache now lol hope this helps |
MBC isn't a good idea. As in winter you can get boost spikes. As the ECU can't control boost.
But it also depends if your having mapped to the MBC as it can be set just right. |
to be honest i think id rather jst hook the 3 port back up and sell the mbc
just need to know where all the piping goes lol and ive heard about a pill that i need to get to put back into the tubing is this correct ? |

sorry to drag up an old post but i reconnected up the 3 port today and the dump valve doesnt seem to want to kick in
with a very little blip on the accelerater i can see the dump valve starting to open but no noise even at 4000rpm,s still nothing , before i took the mbc off it would kick in at about 3000rpm,s ive connected the pipes as above (thanks b13bat) so i cant seem to work it out ? would pictures be of any help thanks again |

What was your boost gauge showing with the MBC, and whats does it show now? Any sign of overboost at WOT? |
heres the pictures of what ive done :)

http://i78.photobucket.com/albums/j8...ob/pulsar2.jpg Can't see the numbers on the smaller pic mate, so i've coloured them. Green=longest run, to turbo nipple.(pic 1 below) Yellow=next longest run to wastegate actuator, you numbered it 2.(pic 2 below) Red=Should go to airbox res, but as you have a ik fitted, it can be left to VTA Turbo nipple, Green dot. http://i78.photobucket.com/albums/j8...nippleee-1.jpg Wastegate actuator, Yellow dot. http://i78.photobucket.com/albums/j8...tegatett-1.jpg Not because i think you have it wrong, but i can't make sense of the pic :lol1: |
hello mate
cheers for helping me out again:thumb: this is where the bottom hose is going (red dot) http://img.photobucket.com/albums/v1...IMG_0201-1.jpg ,should i just vta and block off the nipple end or should i just leave that as it is sorry about the pics before lol |
The hose coming off the bottom of your 3 port normally connects back to airbox, but as said earlier as you have an induction kit can be left to vta
|
Don't know what you've got that bottom hose pushed on to, can you get a closer/better pic?;)
|
hello mate heres the pictures
this is an overhead view , you can just see where the bottom pipe goes (red circle) http://img.photobucket.com/albums/v1...r/IMG_0204.jpg and this one is a close up of it http://img.photobucket.com/albums/v1...r/IMG_0203.jpg i hope this helps cheers |
Yeah thats fine mate :thumb:
|
cheers for that mate:thumb:
now ive just got to put that pill in the (RED hose :wonder:) and im all done , and it should run smoothly again lol thanks |
Yeah, fingers crossed :D
Just out of interest, what was on that inlet before you plumbed the 'red' hose to it, was it blanked off or just left open? |
it had a rubber tip over it to block it off and the 3 port was just left open :)
