Tuning Trying to find this piece

[dajustin]

Hello Guys,

I am new here and have some questions for my project.

Im trying to find this piece of the Manifault its the lower curve from the manifault to the turbo in this picture.. is it custom made or is it from another car that i can search.

Yours,
Dajustin

Looks custom to me.

 

[fingers99]

Custom for sure.

What are you trying to do?

 

[dajustin]

Well, Last summer i build myself a Turbo Cinq 1.1 sporting.

I made the Manifold myself but im no expert welder soo i saw this one on the internet maybe its from another car Manifold or such.

And all winter i didnt do anything with the cinq it was in the garage and im planning to get the engine out and Get it apart and put some Nicer pieces on in it.

Does anyone know a turbo manifold that fits on the 1.1 sporting?
Like a VTS saxo or any?

Only way to do it is either a cut and shut on a standard manifold or a custom one. My guess (nothing more) is that both of those in your pic are going to place the oil drain from the turbo too low (so it does not drain and dies a horrible death).

There are photos of the real thing on the site somewhere.

i can tell straight away looking at that pic the turbo will sit far too low and you will have problems with oil backing up the return pipe into the turbo.

In your pic though, just for your info, the one at the back is what the Novitec turbo's had - the one in front is clearly one someone has made to replace a novitec turbo manifold. There is a guy on this very forum which had said issues with a novitec turbo backing up with oil and not draining properly (it is only gravity that returns iol from the turbo to the sump, it needs to be as downward as possible, and no upwards parts where oil can pool) but can't for the life of me remember his username. fusion something or something fusion - its a blue sei turbo iirc.

Your easiest route is to do like the Van Aaken manifold which is just the oem manifold with the end chopped off and a turbo flange welded on - this means welding stainless to cast which i am told is tricky - involves alot of heat and so the flange tends to distort and will need machining flat after.

The other option would be a completely custom manifold = £££'s. If you do that then you want something like in the pic but with the turbo flange as near to where the 4 pipes meet as you can to keep the turbo nice and high.

Good luck, let us know how you get on with it.

Right, i spent a few mins looking and here is a picture of the novitec turbo setup actually on the car... You can clearly see here the oil return to sump is pointing upwards, quite alot - this is bad.

 

[fingers99]

I have a vague memory of making up a jig. Wonder if it's still about somewhere?

 

[dajustin]

soo what ur saying is that the turbo should always be higher then the return place of the sump.

say like this manifold.

 

[blu73]

yeah, thats a better plan in my view

 

[fingers99]

Yes.

 

[dajustin]

So this should be a 1.1 Sporting Manifold then chop off the plate then cut it off very short and weld it togetter done deal haha?

 

[blu73]

get the flange for the turbo you have or are going to use, work out how high you can chop it and the flange still fit, chop it there.

There is a bit inside that oyu should grind down a bit too - its very thin and will get much hotter than in an NA application and could break off and destroy the turbo. You will see which bit i mean when you look in the manifold but yeah thats basically it.

My turbo sei is 200+ miles away or i would try get a decent pic of mine for you :shrug:

 

[dajustin]

Would be nice to see how Yours is done

Wich turbo are you useing at the moment?
I was thinking of getting a new t15 Garret.

well 2 more hours of work then going on with the manifold

And you mean the piece in the middle of the manifold when i cut it off.

 

[blu73]

yeah the separator bit inside.

and mine runs gt15, taken form an old astra 1.7td iirc.

 

[David C]

Don't know if this is the reason, but a useful bit of info is that on the Alfa 75 Turbo racers, they ran an upside-down manifold for the turbo, so the turbo sat very high in the engine bay.
Obviously more room in a 75 engine bay than a Cinq though.

Over 400hp from a 1.8 8v engine was a good result back then!

 

[blu73]

i have thought that before but it would be right out the bonnet lol... I think if i could weld etc i would make some crazy manifold that has the turbo above the gearbox - seen a polish cento or 2 like this (can't find any pics right now though).

soo what ur saying is that the turbo should always be higher then the return place of the sump.

Not at all.

It can be lower but you need to fit a oil scavanger pump. Makes aftermarket turbo jobs a lot easier

 

[fingers99]

I was thinking of getting a new t15 Garret.

Or T17. I've always felt the T15 was too small, so it spools up quick, produces a horrible boost spike, and dies before anything like max rpm.

Not at all.

But much more expensive. Easier and cheaper to do the welding.
