Hi all I'm wondering if someone can help me out I've got a a4 1.9 tdi 130bhp and was going to buy a 2260 in the new year although I'm not wanting to go serious power maybes 180 to 200 I've been offered a turbo of a 2.5 v6 180 bhp a4 I believe it's a gt2052v now I've looked on the internet and carnt see anyone that has done this maybes someone could share some light it would be great
 
You need an adaptor plate to fit it to the manifold (like THIS) as they have a different stud patten. If you have the turbo already you could get one made up easy enough rather than buy one.

You will also need to make a custom down pipe, and pipe from the turbo to IC as the angle of the turbo is different from the standard one, and it also has to be mounted to the manifold at an angle due to clearance.

Have a search on other forums as it has been done before, but it's not as simple of a bolt on job as you would think.
 
Thanks for the reply I'm almost sure the turbo already comes with the plate and manifold I understand it will need a custom down pipe but I'm a welder and fabricator and made my full turbo back stainless exhaust for the a4 so that wouldn't be a problem. I'm also going to make my own tubular manifold so this would be an ideal time to do it then I could set the angle myself. So is this turbo a good upgrade or do you suggest wait till I see a gtb2260 from a 3 litre diesel?
 
I didn't look that far into it tbh, I just wanted to see how much work was involved in the fitment as it looked like it would be pretty straight forward should my standard one drop it's guts.
If you can do the fab work yourself then it should make it a pretty cheap job compared to buying an off the shelf kit from the likes of Darkside.

I might be wrong, but doesn't the 3.0l turbo have an electronic actuator?
 
If you only want 180-200bhp then a BV43 or a hybrid version of the turbo you already have on the car will do that.

Fitting a 2052 or 2260 will entail all kinds of exhaust manifold changes, downpipe issues, boost pipe changes. If you have a 5 speed car then you will have the smaller 228mm clutch which isn't so good, even with a 190bhp remap you may need a new clutch depending on how many miles it's done. An intercooler upgrade would be good as well.
You can get 170bhp with just a remap on standard parts.

Thanks for the replies. The car is the quattro 6 speed box so has the 240mm clutch which I will be replacing shortly. I understand about upgrading exhaust, intercooler the exhaust isn't an issue as it a straight through. A would put an intercooler on anyway if a was upgrading the turbo so that doesn't bother me. Has these 2.5 v6 turbos been fitted to the 1.9's? Yeah the 2260 has an electronic actuator so that needs converting to a vacuum actuator
 
A 2260 on a 1.9 is not that good a car to drive as a daily. It all depends what you want.
If you have the AVF engine then the standard injectors will be good for around 230bhp , if you want more then you are looking at a lot extra for upgraded injectors.
I think the ideal turbo to go with the standard injectors is a GTB1756VK good for around 225-230bhp will max out the standard injectors.

If you decide you must have more then you can upgrade to a 2260 using the same manifold, The 1756 will retain the driveability and bottom end as well as reasonable fuel economy.
The 3.0 engine using the 2260 is nearly 60% bigger in capacity than your 1.9, the 1.9 just doesn't flow enough gas at lower RPM to get the turbo spinning.

Karl.
 
Hi thanks yeah it's the avf engine. Is the 1756 just a 130bhp turbo but it's been hybrid?
 
Real question is how much your looking to spend, Darkside does some reasonably priced kits.
 
I'm not to bothered about price really. And not being funny but a wouldn't buy anything from darkside. All it is is that I've been offered the 2.5 v6 turbo with maifold flange etc for £300 but not sure if it's worth the hassle to fit. If it was to much hassle I would buy something like the 1756 or the 2260
 
Why not, they do a kit for the turbo you want and you'll need a manifold, map and all the bits and bobs to go with it if you go elsewhere (wherever this elsewhere is, some backyard garage which I would be much less enclined to trust than the people who do this every day).
 
I'm not being funny but why would I want to pay them £800 for a manifold which I can make my self for about £200 and buy a turbo else where. Where I can get it made to my spec if that makes sense
 
You are being funny, you just said your not bothered about the price haha. Let me know where you plan on getting this labour, a new turbo, cast manifold, downpipe, braided oil feed & return, 4 bar map sensor, oil & filter swap and mapping (which less than a handful of people in this country can do for aftermarket turbo's) for the price they charge.
 
Some people can actually do the work their selfes rather than pay other company's that charge a fortune. Yeah am not bothered about price for turbo. But if you read the comments I said am a welder and fabricator so I can go and make a new custom down pipe, I can make a new custom tubular manifold to suit any turbo a put on. Map sensor I can get from the local Tps at trade cost. I can also go and buy braided oil feed and return from anywhere. Oil and filter swap I can still do my self. And mapping I can take it anywhere. Just because darkside is number 1 in the uk for tdi tuning doesn't mean I have to get the part from them or take my car to them just to do the work.
 
The GTB1756 , GTB2056 and GTB2260 are the same range of turbos. they are pretty much interchangeable .
The GTB1756 is not a hybrid version of the turbo on the car at the moment.
If you are getting the clutch changed soon decide where you are going with the tuning first. Anew standard clutch DMF will be good for 200bhp and 310Lb/ft , any more and you will be looking at something like a Sachs Organic. Go for a 2260 and you are probably into a SMF and possibly a paddle clutch. Not very good at all for a daily.
Have a look at some of the Darkside customer and project cars. It will give you an idea of what mods they have done to accomodate the power increases. Somebody who knows what they are doing when remapping the car would be good especialy if you go for uprated injectors and a big turbo. Making power and torque isn't a problem, making it without smoke, reliable and driveable is the trick.

Thanks Karl. I think I will look into the 1756 from Xman. I replaced the clutch 10k miles ago and it's started slipping again so I was already thinking about a Sachs organic clutch when I come to replace it again. And the car will be used as a daily. I will have a look on their now. I already know where Ill be taking it for mapping and they are good

Diesel Jake is right there are not that many tuners in the country who can do a good job with non standard set ups. Big turbo's and uprated injectors are not something most people come across on a daily basis.
There are plenty of people who say they could map it and I am sure they could but to get the best out of these set up is not as easy as you seem to think.
I don't doubt that you are very good with metalwork and fabricating an exhaust or a manifold but that is only part of the work, the magic really happens with the map.
I myself don't rate Darkside they tune lots of fast cars and turn upto the pod with some very quick mentally tuned cars but they aren't reliable as a daily.
Here is the one that turned up at the GTI festival at Santa Pod this year.



It arrived on the back of a transporter they stuck all the stickers on it and got it booked in. As far as I know it never ran at all, or blew up on the first run because the next time I saw it was them loading it back on the transporter.
This car had easily run faster than what I could do but it's not reliable.
Here's my trophy for fastest diesel on the day



I have mapped my previous AWX Passat estate myself with a BV43 to 207bhp and 345Lb/ft of torque and done all the mechanical modifications , exhaust, intercooler , turbo etc myself. That would give a Civic type R EP3 a run for it's money at Santa pod running a 14.95 at 93mph. So I have an idea what I am talking about .

All Mattty really wanted to know is if the turbo was doable on a 1.9 engine which he found out. He has stated he is a welder fabricator and is fairly knowledgeable around working on his car as I know him personally so the only thing he will need is a map doing. I have had fab work carried out on my car off him and can confirm definitely not back street quality and personally I would not use Darkside as I have had snidey run ins from them and think are extortion. Their is more company's than dark side who are also great with diesels.
 
Thanks Karl I know what your saying. But the tuners close to me are good. Well if they went good my mate wouldn't take his drag car there haha. I agree about it's only part of the work with the manifold etc. That's not a bad run for the weigh ect. So your saying for a daily the 1756 will be the better option?

Matty
 
Well if I answered the original question can you fit a GT2052V turbo onto his engine yes you can.
But I know for a fact that it's not the one I would choose and wouldn't give as good a result as something like a GTB1756VK or GTB2056vk. These have the latest 3rd gen VNT design which is much better than the VNT in the older GT2052V.
They will spool quicker and with lower back pressure making the car a lot better to drive and improving performance and economy.

Karl.
 
If you are going for a Sachs organic clutch and keeping the standard injectors I would go for a GTB1756VK and aim for 225-230bhp.

Karl.
 
Thanks that's helped a lot. So the 1756 is a bolt on or is there other changes to be done. Like down pipe, manifold? Al be putting a front mount on and custom hard intercooler pipe work

Matty
 
The 1756 requires a manifold and best to fit a FMIC whilst your at it as the boost pipe fitment is different to the standard turbo.
The downpipe is different to a standard turbo, you can buy the flanges and make your own.
Sorry to link to a Darkside auction but gives you an idea, other people sell them or you can make your own.

http://www.ebay.co.uk/itm/GTB-Turbo...arts_Vehicles_CarParts_SM&hash=item1e674c7d62

Probably the work of a weekend to fit the manifold and turbo sort the intercooler and fab up a downpipe. You could drive the car on the 1756 with the standard map till you can get it booked in for the remap.
This was one of the funnier runs I had with my Passat, it had only just stopped raining recently, you can see the clouds and wet patches on the ground and this was one of the first runs after they reopened the track hence the slower times.
But the guy in the S2000 wasn't very impressed being beaten by a diesel estate.



Karl.
 
Al get some pipe ordered for the manifold ready for the turbo. Yeah a fmic will be getting fitted. I will probably make the flanges or get my mate to machine them. Haha a don't he would if been to happy either.
