ST170 Turbo Engine Rebuild - CGI - thinking of selling up!!
#121
Thats awesome, let me know how that comes out. Would you be interested in making another CF middle plate for c.o.p.'s ? if so I'd be interested...
Also what brand/part # are your cops? I'm looking to run it on megasquirt. This is going to be interesting for me as no one has run megasquirt on my car model (ford escort zx2 , U.S. car)

also forgot to post your vct delete: https://zxtuner.com/displayProductDo...&categoryId=17
and also your obx header, make sure to make a reinforcement from the header flange to the turbo flange, there cracking them here in the u.s. because the welds are weak.

The link you have given above is not for a focus SVT hence why I went the route of having one mached up myself.
To be honest I'm now having a set of custom billet cams made which removes the need for a spacer altogether.
Most tubular manifolds will crack when you have a 10kg + turbo hanging off 12"+ of cherry red hot tube and vibrating like mad at 7000+rpm.
In the past I have used an old valve spring welded to a support bar to support the weight of the turbo and to allow the primaries expand with the heat. It works well
Manifold will be similar to the above design but slightly different

Indeed its always worried me about having a manifold which puts the turbo over near the battery tray in the mk3 fiesta but i want one anyway and im hoping i can sort some bracing for it.
Loving everything you have done so far mate.

svt focus intake vct and contour/zx2 exhaust vct use the same vct cam gear. The adapter works for both.
Which exhaust mani are you getting then?
good luck!
p.s. keep the pics coming, I like seeing whats going on!

Car is making progress.
Stripped the car down to chasis and in the process of lightening everything completely.
Carbon panels, carbon seats, titanium bolts etc etc.
Reckon I can take 50kg out the car if I try hard enough and get it to 500kg or below
Valves have come from the States and head is getting done as we speak
New prop and diff are here
will update pics when I get time

You can get dimensions of the PWR charge cooler range from there website.
As for the pulley wheels there a bit of a hybrid I have used from another model and adapted them to fit.
CGI block has finally come so it is currently being machined and bored.
Will post up pics soon

Dennis doesn't know much about turbo's or Zetecs IMO
Duncan has rebuilt my box and diff though

PassionFord Post Whore!!
I wont go any further on that Austin are you going to dyno it on his dyno though or go through to Harvey ??
Would look to catch up and take a look at it some stage mate when i'm up your next of the woods next, who knows maybe drop down for some clay shooting as well

Not in a major rush to get it done as I've got loads of other stuff on the go at the moment
Also recently bought a couple of 5 cylinder volvo engines I'm going to go mad with.
One turbo'd and one nasp
Will come along to a meet when its done.
The ST170 is the same as the Focus SVT

Very nice car Austen.
What kind of turbomanifold did you have on the car during Ten of the best 2006?
And how did you like it?
I will build an engine with hopefully 400-450 bhp.

Got mine from here:
http://www.chevroletls1.com/zetecturbo.html
Fitted well and made the turbo spool up quick but for ultimate power the design is not the best.
You need to use a T3 flange on your turbo with this type of manifold
Should manage your figure with an external gate attached to manifold
I had a 38mm take off welded to the side of the manifold which worked well for the external gate.

Thanks Austen.
I am after fast response rather than a high bhp figure.
So think i might go for this one as it is a cast unit for long life instead of a welded manifold, i see its also possible to get it with a flange on the top and on the bottom, might be easier with the wastegate fitted this way. How wold you think it would work with the wastegate mounted this way?

try using one of these instead
similar money

If you go with the cast one i would mount the wastegate on the side rather than the bottom to assist flow, but it all depends what room you have.

Hi Mark
Yes I've herd that too about the Norris Car, and realise he went back to an IC setup.
I'll be running alot less boost and power than that though
The problem is that I have no room to put an intercooler of any real size that would be man enough for 500bhp plus
It would need to be the same size if not bigger than an RS500 style cooler which is impossible under my nose cone
My last chargecooler set up was based around a Pace 3 core unit as used in the escort RST kits. These are supposed to be bad according to everyone on here but I actually think it work fantasticly after looking at the logging. I used to get temps of 10 deg c above ambient which I was very happy with when giving it abuse.
If stood in trafic it did suffer from heat soak though
With a chargecooler setup eveything has to be spot on or you will get problems like the standard Pace kits suffer from, (small pumps, prerads and pipework)
I'm using a large Bosch water pump, 19mm pipework and the largest prerad possible I can fit under the nose cone which I have also ducted in to force the air through it.
I know its a trade off but the best I can do with the space I've got
I have a friend who has used one of these before on a decent setup and he reported good charge temps from the logging on long blats out and track days off the logging
If I get charge temps to the same as before on a little more boost I'll be happy so fingeres crossed.
