Yeah, the M3 has all the throttles linked for the ICV and servo takeoff. Can always do it later I guess.
Not sure if it makes any difference, but I think the cossie injectors are all low impedance aren't they? From what I understand, some ECUs can be set to expect the extra current draw, some need a resistor fitting to increase the impedance.

these are Ford light greens from a Mustang Alex, imp is about 12-14 ohm so same as the stock 715s.
The MS can be set to operate low imp units with a toggle in the embedded code, earlier production units req a flyback boaurd to prevent surges on the FETs, mine is the revised 2.2 version so its modded on the main PCB
they have upgraded to a V3 now but its pre production so best left to the experts for now, maybe upgrade to that and the MS2 daughtercard in the future as/if req.
What injectors are you guys using again ? I think we discussed in the past but I'm too lazy to look it up

my iscv is the two wire type as fitted to most vauxhalls!
As far as injectors go im using some from a 3.0 big 6 bmw!
cant remember the p/n but i know they flow 213cc/p/m!
if you guys are using single back boxes i strongly recomend you either get
good quality or repackable types! mine sounded gr8 with one box
but one evening i was giving it some right foot and see sparks out the back!
next thing all the gutts had come out the box and sounded like a tank
5" tailpipes work like amplifiers when theres nothing inside!

Was thinking I might make the can in two halves and either tack or rivet them together so I can re-pack them. Presumably the amount of packing in them could be used to change the volume of the system to an extent?
I'm using the injectors from a Peugeot Mi16 which are supposed to be good for 45-50 bhp per cylinder. Certainly people have had over 190bhp from the Mi16 with standard injectors so think they should serve me well.
Nice and cheap too

Thats what Im doing on mine. Ok its not turbo, but my plan is a twin 2.25" system (standard S50 size) into a single re-packable backbox.Turbo-Brown wrote:Was thinking I might make the can in two halves and either tack or rivet them together so I can re-pack them.

Like Ant said, it will be easier to add a box later than remove one.
I would guess that the more packing in the can, the less resonance there will be. Not sure how much the sound level will be changed though if its straight through.
What difference does this cross-over pipe make in the system then? Ive heard a bit about them, but not sure if I need one.

From what I understand, teh cross over pipe makes quite a large difference to low end torque.
One of the guys I used to work with used to build race engines for pre-war sports cars. He said they found quite a large difference on the dyno when they fitted just a 90degree crossover pipe between the 1-2-3 and 4-5-6 pipes (it was Invictors he used to work on)

So it might be worth me putting a cross over in my system then? Do you reckon it would it make a difference if there was a centre box in place?
When you say a 90degree cross over, you mean so it looks like an H. I guess a cross over that looks like an X would be best though, like the ones on the BTB 6 branch group buy.

What's the manifold from?

Looking good ant 
Have you run it yet?

I asked the same questions when I saw the pic last night!!!
Damn tidy install, hope mine looks half as good
Thats a BBR (brian brody racing sp?) manifold, really compact unit, but it has a big internal diameter, was shocked when I picked it up how big the ports are. Makes mine look a little on the skinny side
Ant, MS is off to Bill today, should have it back by the end of the week

Good call Mark, input protection Zener has failed I rekon based on last nights testing( you gotta admit it was educational) Bill is D man, he'll sort it out no worries
the manifold is a Brodie Britain Racing unit circa 1991, they did a kit using a T2.5 hybrid as a retrofit kit for Ԛ£6K
Samco hosing was bought brand new off ebay as a full cossie RWD setup, so not as much as you'd think
majority is going to be hard piped, just samco where the pipes meet the IC and TB really dudes.
thanks for your kind words too, its getting there, Mark yours is gonna be double hardcore looking
Oh, yes it does run( badly lol) but blows boost to atmos @ the mo until the revised IC setup is in place, getting a bit frustrating now TBH

But TBH as long as it works I couldn't give a flying f**k what it looks like, just want the Woooossh and the pschttttttt!!!!!
MS in boxed, sealed and labelled all ready to go, Bill has emailed me, I've updated him on what we found last night and to quote him "Bung it in the post and I'll run it through a full check. Not found one
I can't fix yet." Now that's a confident man and I like it!!
If it gets back in time I'll be heading down on Sunday for sure

Ive decided after a bit of a tuning session last night (1/2mile away) that its running a tad hot!!
So ive gone and got a water pump for water injection!! its a monster! if its too big it will be great for a chargecooler! we will see.
Chargecooling...hmmmmm....nice.....where you gonna fit that then?lentec wrote::yeahthat:fozzymonster wrote: But TBH as long as it works I couldn't give a flying f**k what it looks like, just want the Woooossh and the pschttttttt!!!!!

Only ones I seen are rather large and take up quite a bit of room, pics please??
This looks quite small
Thats looks very nice, but still got no idea where you can fit the bugger under the hood tho and in a place that means no extra long pipework, will be interested to see where you stick it!!
So does that go between the exit of the rad and before the cooled water enters the engine?
I've been looking into water injection on ours too, seems MS can do it afterall, this box of tricks we have is getting better the more we look into it, just got to figure out how to make it work now!

The little pipes go to a water pump and front mounted rad!
Perhaps i might look into getting one mounted on top of the charger!?
Then i can keep my pipes
I am trying to avoid water injection as thats what killed phase1

Was getting a little woried about this tapping that was comin from the top end
it was more than the usual tic so re adjusted the lifters to 12 thou
its running real good now! its only boosting at 7psi but if i can get water injection fitted again it will go back up to 10-12psi!
Throttle responce is mental now! hit the charger,foot to the floor,BANG your at 4500rpm (i am running it in after all )

Ant, that looks very nice mate 
Little update from me:
Got my exhaust downpipe back from an old work collegue, fitted it all up, not witha gasket as it was mearly a fitting exercise, connected the afm to a pipe connected that to turbo, air filter on and turned the key.
Its much quieter with an exhaust even though it is leaking from about 2 places! But its running very very rich, so tomorrow i might try 1st playing with the air flow meter to see if i can trick it into thinking less air is flowing through. Secondly i might try the old injectors and see what happens, see if it pinks badly.
But today i heard that turbo spinning properly, sounded so cool, just like blades spinning fast then slowing down(i wonder why ) It gets so physically hot so bloody quickly, (turbo, mani, downpipe) so i'm waiting on my forgetfall old man to borrow some reflective tape from his work to protect all the wires in close proximity.
I'm gonna try and borrow i video camera tomorrow so if i'm successful does anyone have any ideas where i can host them free!

Thats excellent news dude, big slap on the back mate!
I've just bought some exhaust wrap for the 'hot' parts you mention, might try that refective tape too, save any melting wires
Have you chatted the the guys stateside about setting the FMU and AFM up? They're quite a few start on that setup before going to a ECU.
I may still have the M30 AFM coming back soon if you wanna try that too?
Mark.
Tripod have free hosting i think its 20mb they give you!
I managed to get phase1 running with a jaguar xj6 afm its nerly two times the size of the standard m20 unit and the circuit from our bosch unit fits in even tho it says lucas on top!

I would love to show you some pics, but all my goodies are in Ant's garden shed!!glenn wrote:how's about a few more pics off you turbo guy's?
it's nice to see how other's are getting on.
All I have is the intercooler mounted and lower valance, cut, filled, repsprayed and meshed. The ECU was fitted, but now I just have a hole in the dash as it's currently with a guy that is servicing it for me.
Other than that I have nothing to show other than a box a parts and some pipes!!
Pics will be added asap and vids too
And vids of your beast running yet Glen?
As you asked so nicely glenn....
I'll have to get you some tomorrow as i'm in a rush but have still found time to type some stuff here quick!
I took it out for a drive, just a real quickey.
It's so nice to be back in the bmw after a g plate escort, the seating stance feels like i'm sat on a go-kart, truely unbeliveable after not driving it for 4 months!
I'm afraid i didn't take it beyond 2000 rpm as the everything needs settling back in, the brakes are binding like a mofo, just wear it off in the end i guess. But i am having a brake problem, when braking it judders the whole car up to the steering wheel! and you get a massive loss in braking performance. It maybe the abs, but i think its not as i've had a problem with abs before and fixed that so i don't think its the same thing.
I have a feeling its the boost pressure backing up the vaccum, but i thought it had a one way valve, will have to check it. It was a bit of white plastic with an arrow on so i assumed that it did have one, perhaps i should never assume whilst turbocharging a car...
It is running smoother since changing the spring tension in the afm, so happy about that, but its still overfueling as my brother said there was a massive cloud of black smoke when i accelerated very slightly(he was watching from side of road)
My dad was in the car on the "test drive" and thought it was pinking, made an audiable clickng noise so backed off straight away. I think i need a boost gauge so that i can see whats going on, as i have a feeling its overboosting really quick and the wastegate isn't opening....
But apart from that... loving it, and i could feel boost whilst hardly accelerating!!!
Will post some pictures tomorrow in the afternoon probably, hope you can wait glenn!
Have fun guys, as i most certainly am!
Jon
P.S my brother just mentioned that a car footpump gauge might work as a boost gauge, any ideas.

I think it is a one way valve jon..
i`ve had no problems with my brakes
maybe the valves porked ?
get a boost gauge so you know whats going on..
foot pump one should probably work ,might not be very accurate though.
I started off with the wastegate open and gradually increased the boost..

I've got one intercooler on and the other is close behind
This is one of the jobs I've been putting off so it's nice to have it almost complete!
They're not exactly subtle though, will post some piccies tomorrow if I can!
