I think we have a comp' housing pairing to go on now...
The .42 cover is simply an Escort RS/Cosworth T3 comp housing. The 4x4 was the easiest to use as the wheel profile is the same for the 60 trim wheel so no machining was required.
Ford weren't the only people to use the .42 comp housing though, Renault, Nissan, Saab just to name a few.
but are they also using the same .49 to make it 'responsive'...
Wonder why K-tec didn't simply fit the 28rs cover (and wheel) with its moulded-on inlet & outlet?
Edit. Or even the 28rs itself full stop.
That's what is left to guess upon really. Personally, I think the .49 housing is a total waste of time, on anything
I'd put it down to cost, especially when I recently compared the RS to the 2560 core recently.
was that a recent comparison?
ok, a couple of months ago, it was a few hundred quid more. But prices have been up and down like a yo-yo for a while.
you missed it
I noticed what you meant after I posted
Forgot I had the installation instructions on cd so had a quick flick through and found these
Maybe we should rename this thread to "Name that turbo" LOL
Heres another
sh!t thats tight!!No way could you use that manifold in a 5.
Thing is do you like the car, does it feel quick?
That's the same actuator that's supplied with the GT2554R...
I like how they've routed the rod too, jokers

Yeah it is a noticeable difference, but for the money spent to get to this point is it not worth spending a little extra in the form of low comp pistons to retrieve effectively the same increase again?
Remember though that when you drop c/r the engine will feel flatter off-boost. Also to yeild much more than than 240hp or so you'll really need that bigger exhaust turbine that Andy describes. Maybe you already have it on the turbo, it's hard to tell from the pictures
I've not seen that many turbos, but I've only seen that actuator arm on a .49, what say you Adam?
That actuator rod is errm... ****, just as well it's low boost
I don't think you'd get a GT28RS in that gap, looks very tight.

Just thinking that, will the seals not fail in the actuator?
Could it be struggling to make 7psi due to the actuator failing?
Remember im a newbie so don't shoot me down
I'm gonna go for a 25r/28r 62trim hotside mated to an old skool T3 60trim esque cover.
you're the guy with the dyno run showing boost, does it hold 7psi?Just thinking that, will the seals not fail in the actuator?

Ehhhyou're the guy with the dyno run showing boost, does it hold 7psi?
sorry, too much beer, thought you were the OPEhhh
as you were...
Likewise thought i had wrote something stupid... againsorry, too much beer, thought you were the OP
I actually think that turbo is a GT2554R, the .42 a/r fits over the 54mm comp wheel too, with some fiddling.
That fact that that's the actuator that's supplied with the above turbo, and the blatont excessive effort that's gone into routing the rod tells me they clearly weren't bothered about trying another actuator/bracket...
Right everyone managed to get the dyno graphs scanned.
there you go, it's only got 0.4bar at peak power, that'll cost about 15hp. It's set up pretty rich too - maybe that's because of the high CR.
The boost control is pretty poor all around.
Not to sound like a complete muppet, but any idea why its dropping off?
I'd need to be mystic, but at a guess it's the backpressure blowing the wastegate open (the alternative is the turbo running out of steam). An electronic boost controller would probably fix it.
Heres another pic that might help identify the turbo
Have you got one that shows the compressor wheel clearly?
Afraid not mate those are the only pics of the turbo
just to update this, I've just got off the phone to universal turbos who supply Ktecs turbos and they've confirmed it's a GT2860R with a .64 back end.
So there we go mystery over, don't know why i didn't think to phone them sooner.
Now then what do we think it's good for?
Garrett rate it to 330bhp, but with that .42 comp housing it won't. Your engine won't be capble of that either though.
I don't think the turbine is up to that with NA cams either.
Just stick a boost controller on and see what happens. Where does the actuator pipe connect to?
Intake manifold right on the top.
Not really sure which direction to go now.
1.Stand alone management? I've been led to believe that if I opted for something like an omex I'd be able to have a much greater control over all the engine functions and run it at a higher more controlled boost level.
2.Low comp pistons and rods? This would bring me up to the Ktec high boost standard which there are currently a few clios running around the 300bhp mark in this guise.
3.Boost controller, deactivate the vvt and remap? The boost controller has been recommended by a few people on here but another avenue I'm exploring is the VVT system on clios. basically in the dephased state 0-1800rpm there is very little overlap then above that threshold it adjusts by something like 16 degrees and introduces more valve overlap. Now I've been told that vale overlap is good in NA but bad for forced induction.
4. Custom turbo cams and remap.
Or all off the above (I wish)?
I did have a ride through to turbo pacs yesterday to see what boost controllers they sold and just to have a general chat about turbo cars, they said they'd have to get the car into look at it first before they could recommend any thing.
I then did a search on here about them and realised they're not the most popular tuning outfit. LOL
Any body think of anythink else I could possibly look at?

1 - your ECU isn't what's holding you back, if you're happy with the way it drives it's OK. The mapping is down to the guy with the laptop, not the box under the bonnet.
2 - pistons and rods, well maybe, but much more than 0.5bar will be hard on your gearbox, you are kind of at a crossroads, either be prepared to break and replace stuff (this is part of the fun to those that do it), enjoy the ~0.5 bar for what it is, or spend the money on a better car.
3 - I'd do this, the controller will get you the boost you should be running, it will want to be re-mapped at that boost. At the same time you could play with the VVT, it may, or may not improve things. Ask the mapper if it's supposed to be that rich.
4 - turbo cams are for small turbos, get the right turbo and you can use whatever race/rally cams you fancy, get it wrong and it'll be a dog.
and, err, Turbo PACS.....
Put it this way, i'm not sure they've subscribed to the good garage scheme!!
food for thought, mines lower CR, runs 7 psi, has the VVT enabled, NA cams, 50 trim T3 turbo with 0.36 rear end and made 238bhp and 230lb/ft at motorscope last year. So im not convinced its the cams or the VVT... i'll scan and upload my graph later.
Cheers Ash
Who mapped yours for you?
Andrew I did think about changing cars as I was looking at the new S3's however I've had my clio since new (Sep 2005) and have kept it absolutley mint inside and out. It's only covered 31k. FSH etc....
So rather than selling mine and letting somebody else have the fruits of all my hard work, then have to add at least another 15k+ to what ever I sold it for, I thought I'd have something a bit different and reap the benefits for myself.
Heres another pic that might help identify the turbo
that exhaust housing looks is if its had a crack repaired
Think it's just casting imperfections
Blocky does my mapping for me!
Ash, yours has standalone ecu hasn't it? any idea what make?
Also any idea what Scoff's running?
If not I'll PM him.
Ktec are talking about the omex 600?
scoff runs adaptronic, which he sells and installs.
ashy, why such a small turbo?
you should both take a leaf from scoffs book and get on the t04e bandwagon for sure!
we rocking our china £100 t04e now on our little 1.6 honda, and its not too laggy at all, im sure it would spool even faster on your motors, and blows a gt28 into next week! our civic with the t04e hauls ass, and you have all seen scoffs car
How big is it? as it's tight as fook down the back of my engine lol
Just because it was available when I built the car, I wasn't planning on keeping it on tbh but it suits the engine realy well... I'm happy with the level of power I have and how the car performs! Its very responsive from low down and pulls all the way to the limiter and has prove to be reliable at that level of boost.
Its not built to be a 1/4 mile destroyer as I want to be able to use it on the road and track... So a bigger laggyer turbo is'nt really what I want.
Also if I go for more boost I'll need bigger injectors and a new clutch and I can't be arsed to pull the engine out again! Maybe will when I get it painted
You'd need new manifold mate as its a T3 flange turbo... Plus ur right it wont fit down the back of yours!!
