Hi all,

Unleaded cylinder head with bronze valve guides,
10 row oil cooler. and maniflow turbo single 2" box system.
Ive just orderd a T-hose for the dump valve i want to get.
Im still learning stuff, did a search, but still not 100% sure what i do.

So i Need.
(1) 8 (psi) Needle
(2) a bleed valve, Can someone show me what one i get.
And still not 100% how you fit and boost it up. is there something that has to be done to the fuel also ?
And what else would you say i need to get and do to get this all up and running.
Be great if someone could inlighten me.
Sorry if this has be asked before. but i just need bit more input.
Be more then greatful if someone could help.

Most people on here use a single piston Baileys or a diaphragm type from Forge. After doing a lot of research on this, Baileys are of the piston variety of DV and some people have reported that the seals in this DV swell with fuel contamination and this results in the piston sticking open. The forge type are diaphragm type DVs and these don't have this prob but instead the diaphragms can split. However you can get uprated diaphragms for them. I don't think there is any benifit of a twin piston type on an A series, they are for cars with air flow meters (??).

The DV in the first link looks like this one...

Might save you a few £££s.

So now i need a bleed valve.
What sort of valve am i looking for. ?

Shit Happen's

Hi,
Bin the ECU then you'll run 7psi, couple of turns on the acutuator and it'll be 8psi. It'll perform better than with a bleed valve too.
Get it set up on a rolling road, that's essential.
Cheers,
Gavin :)

How do i find the ECU.
Where the arow is in the picture,
http://allyoucanupload.webshots.com/v/2005210676811873359
It's blocked.
Doe's this mean there is no ECU ?

Shit Happen's

Hi,
Not the one in the picture.
You need to follow the pipe from the actuator to the turbo compressor housing and fit a Manual Boost Controller (MBC) Ebay is the best bet
Sorry my mistake, the standard actuator only runs 4 psi.
With the MBC you'll be able to set it to 8psi.
Set it up on the rollers, think about putting an intercooler in.
Do a search, it works well on this site, try ecu or boost or mbc or bleed etc.
Cheers,
Gavin :)

Bat is right. Go to the other side of the carb and take a pic, we'll show you where you need to fit the bleed valve/mbc.

oh yeah, when you plumb in your DV you need to think about where you are going to get a vacuum take off to open it with...

Well i cant do that now as ive taken the carb off. and in bit's, as ill be rebuilding it with a rebuild kit.
But i found this picture of the net if this should help ?mabe if you dont mind, you could draw onto the picture and tell me where i fit it etc. that be great.
http://allyoucanupload.webshots.com/v/2005938573859686617

And in the link below, is that the (MBC) i need. is the bleed valve the same as a (MBC)
http://cgi.ebay.co.uk/Manual-Boost-Control...1QQcmdZViewItem

As for a vacum take off. the car has one of these fitted, boost gauge.
To be honnest i dont really understand what it tell's me as such.. but could i came of this ?

Hi,
That looks like a bleed valve to me, despite the description.
The engine picture's not much use other than you can see the actuator. Try this link from the "How to" section of the site

Unfortunately someone has stolen the pics, Iain?
Cheers,
Gavin :)

Reet,

See that "loop" that runs from the actuator to the compressor?

Well, the bleed valve goes between that, ie, the actutor if fool it is getting less boost where as the engine is getting more therefore more power.

It is worth making that loop longer so it is easier to get to and make sure it is out of harms way, ie not too close to the exhaust manifold etc.

If you want it in car you can put a T piece in that loop and run into the cabin, the bottom outlet on that ebay valve is the outlet, that can just go atmosphere. If you run it in car just block one side of the valve.

Hope that helps.

Can someone show me some pic's please, of what they have done.. and how do i know if i still have a ECU. i brought the car of someone, so im still not 100% on stuff :)
if there a part on the site that shows me stuff, ive searched not not really found that.. thanks for your support

So the pipe at the bottom right, where's that going, to the solenoid ?
And is this what i want ?

If you want it mounted in the car so it can be adjusted on the fly then try this...

If you want one as in the pic above (ie fitted and adjusted from the engine bay) then...

Ok cool. so say i have it in my car, can i have it on the dash board.and if so, when i turn the boost up, could i get something in the dash to tell me what boost im running at. whats the fly ? lol i just got a haynes, so im getting the idea of it now.as i didnt know what the part's were that were said in what were talking about.. so was lost. getting there though thanks to u guy's.
plus is this the solenoid i have to get rid of ? as this isn't on the regulator ?
Thanks guy's

If you want more boost just pull the wires off the solonoid, it does make a difference, I have owned 4 Mtero turbos.

It will go bang eventually.

Have fun.....

JF.

What will go bang eventually, the engine?
So that not a good idea then..
