T5 tubular manifold

[cherry1809]

Is there an off the shelf manifold available anywhere?
(Getting near to my claim pay out (had a good first offer but you always turn down the first))
Trying to get some parts together for the engine build. :)

[Volvostorm]

I have seen them for the focus, and when I was talking to them they reckoned it would fit.

But, I can't remember who made it!

Might have been these:

The manifold I was looking at was tubular though

[Nealevo]

My friend has one in his rs focus I can ask where he got it from as it's basically the same engine...

[Rnash2002]

The only problem i can see is clearance because theres not alot of space at the back on the engine,just get a s60r manifold and port it out.

[cherry1809]

Yeah, was lookng at one on ebay for £100, just wanted to see if there was others available.

[Wobbly Dave]

Holy thread resurrection!

I already have an S60R manifold - however if I want to run a GT series garrett, which has a T25 exhaust housing (genuine garrett part) - issue is how to mate it up? Turbo Dynamics say they wont hybridise a GT2871 with a T3 housing?

Any ideas how to get around this problem? Will said T3 manifold fit my cylinder head?

If you can get me a t25 gasket ill draw it up on cad and see how much difference there is. I think uoud beable to get it machined

[claymore]

Mine just has an addapter welded onto the original t5 manifold, you can just about see it here:

I was concerned that with an adaptor, it would make things difficult on firewall clearance. But obviously not!

I may just do that. Cheers for the offer.

As you can see, there's plenty of clearance.

[Volvostorm]

Mine is running a T25 flange too, I had a T25 flange welded to the end of a ME7 manifold, then retapped it all.

[Wobbly Dave]

Sort of thinking now that this...

17142
Will serve me better - less change of direction. Online research tells me it should clear & has the option to run an external wastegate should I want to.

Ohh, I like that, do you have a link?

[Wobbly Dave]

I have emailed them to double check about clearance & fitting.

If it goes on the newer T5 engines (2006 onwards) - I can't see why it wouldn't fit the older stuff.

[Wobbly Dave]

Only issues I can see is that the orientation of the inlet housing would have to be rotated. I am also wondering about the WG position?

[Wobbly Dave]

There is also this - but its in Isreal!

Same one I posted :)

If it is the same company I spoke to at Ford Fair 2011, they were sure it would fit the 850 engine, if fact they said as it was designed to fit in the focus engine bay, we should have no problem as 'ours' is bigger.

[glock19]

Check out brickboard (or something similar) which shows you can't fit one in the older models unless you want to run the post turbo hose downwards. You have to put the hot side on the passenger side and compressor on the drivers side (RHD). Not worth the effort for the power gain.

Imagine how the P-II models are running and you'll get the picture.

[Wobbly Dave]

I've been exploring options & online research

drew me to this... - http://www.lgspeed.se/produkt.php?kategori=16&id=72#

Wrote to LG Speed - Lars was not convinced it would clear the brake servo - which is a real shame.

I have not heard back from J W racing yet. I have tried phoning them, but no joy.

I guess I am either going to have to weld on a T25 adaptor OR get something made OR use a different turbo that has a T3 inlet as standard.

[Volvostorm]

Owen Developments could supply me with a GT3071R with a T3 housing, only reason I didn't get one is they run out of housings and weren't getting any in few a few months, give them a ring, they can build nearly any turbo to your spec.

[Barnsley-Bill]

I made these for my GT 2871 turbo

Then welded up :)

[Volvostorm]

My GT30 is fitted the same way :)

[glock19]

Why weld when you can bolt it ?
Does anyone has a GT35 with the Japan manifold ?

[Barnsley-Bill]

because they allways blow/vibrate loose that's why and a £££££££ to get' to tighten them back up.

[glock19]

Agreed that loosening could happen but as mentioned, with heat and vibration, a complete piece with uneven profile has different expansion rate - and this might hasten the demise of the manifold (crack). The welding of the plate itself has already distorted the cast-iron properties of both the manifold and turbine making them more brittle.

Please note that I'm not undermining your efforts or views but just my concern as most tuners (low and high end) do not make this a practise.

[claymore]

Mine hasn't cracked, and welding the addapter seems to be the common way of doing it on our Volvos

[Barnsley-Bill]

Neither has mine after a year and a half since I did it' use the right tig filler rod when welding is as good as the thing your welding.

Who did your welding?

[smithy]

Who did your welding?

I can get welding done dave a mate of mine has his own welding company and is top notch mate

[glynroberts]

Absolutely correct!

[Barnsley-Bill]

Mark at brailsford bros Barnsley' I didnt trust myself to weld it and he's the best tig welder ive seen. http://www.brailsford-bros.co.uk/

[graemewelch]

What filler wire was used to weld it. Guessing 309L was used. Dont under stand why no one gets the flange machined to suit. Im certain it could be done.
