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

 

I take it it's a VTA DV?
Can you still hear it venting as it normally would when driving?
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


i assume this is the right way round
i cant road test the car as its sorn at the moment but i did manage to drive it up the driveway and it struggled to run ? it kept trying to cut out and it was spluttering
lol
starting to give up lol just treated it to a new set of tyres and an alloy wheel refurb lol
sorry for being a pain and thanks again

i did try to resize the pictures but like all things today its just not happening

 

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.


Wastegate actuator, Yellow dot.


Not because i think you have it wrong, but i can't make sense of the pic

 

hello mate

cheers for helping me out again

this is where the bottom hose is going (red dot)

,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)


and this one is a close up of it


i hope this helps
cheers

 

Yeah thats fine mate

 

cheers for that mate
now ive just got to put that pill in the (RED hose )
and im all done , and it should run smoothly again lol
thanks

 

Yeah, fingers crossed

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
