1.9 16vmjet Turbo upgrade GTB

As in title got a 150 mjet and gonna fit a GTB turbo, have 2 I've ruled it down to, GTB1752v, or a GTB1756v

I want about 210-220bhp in end
Good low end and mid range but want it revable

Sense tells me the 56 is more long term worthy
Head tells me 52 is probably a nice upgrade without bearing too peaky?

You can get this power with both of them but you have to use them pretty much at maximum to get this power more exactly 1.7 bars ...more boost and turbo dies fast.I would suggest gtb2056v from 2.4 jtdm or gtb2056vk from audi q7 3.0 tdi both can do 2 bars so more then you need.Actually 2056vk from q7 spools similar to 1756vk from 2.7 tdi .

theres a 1756 on ebay at mo but would need converting to vac actuator on top as flanges adapting etc
http://www.ebay.co.uk/itm/AUDI-A4-A6...item2ec606243c
and I cant comment if right layout for oil lines flanges etc but the other guys should
did ryan have any second hand units converted, or just new units?

With your turbo choice also consider the amount of work to get it fit your JTD.

Imo, all those Audi turbo's will need so much adaption you will be best off with an Alfa turbo costwise.

For maximum performance and the widest powerband, take the GTB2056v.
If you want to get a cheaper unit that also supports 210-220 hp, you can also consider a GT2256v or BW BV50, all used on the JTD 2.4 engines.

as I mentioned in earlier thread the costs could soon get out of hand once your after 190-200hp plus
im not sure what your std diffs going to think of 400-450nm, and clutch and flywheel may soon give up, to get benefits of larger turbo a better intercooler may be required not sure what the original smic does at 2 bar boost temp reduction wise.
also where in staffs are you? I go back to stoke regular and it seems to be speed camera capitol.

You're actually buying a turbo for only 20-30 bhp because you're current turbo can do 185-190 bhp @ 1.7 bars.
2256v haves old type vnt system which is slower and clogs frecvently ,gta /gtb haves different vnt system,faster and doesn't clog easily with calamine.
My suggestion is to stay away from bv50 or any kkk turbos,it doesn't cope well with high boost and kkk doesn't sell a rebuilt kit for any of it's turbos so if it breaks you'll end up buying another one or rebuilding it with aftermarket turkish or chinese parts.KKK does not sell any rebuild kits!!
If i were you i would take the 2056v from 2.4 jtm should be easy to install.

I'll put it simply, cheapest I can get a GT1749v for is £240 off an 04 car done 84k

I can get a Brand new genuine Garrett GTB1752v for £400.. a standard doesn't make sense really anymore

The GTB2056JTDM turbo is easier to fit, as Js has above, I've read his thread 3 times and tried numerous sites and breakers, I've only found 1 of them turbos in uk and that's a recon at £700 with no known history

Any of them will require injectors to reach full levells and FMIC and obviously mapping of some kind, I say of some kind as ringing a local turbo re mapping specialist he quoted £220 and take half an hour to 45 minutes.. I'm not the slowest with computers but after reading threads by Js, Sussexa and others on adjusting Vnt values and altering smoke maps etc I think he's Hugely underestimating what I wanted

Either way I'm doubling monies with a JTDM turbo

The 2.4 early jtd turbo however is cheap but as above and said yourself is the far less efficient type, infact I've read four threads so far of people upgrading from it, 2 saying once tuned it becomes really laggy and it put me off completely

I have tried GT2256v and it'is not laggy, surely, If you set vnt map properly.

The problem is hold tecnology. It isn't capable to hold 2 bar for a long time. I have broken one in a few kilometer and now I have choice GTB20

a gtb2056 on ebay now(£420)
http://www.ebay.co.uk/itm/Alfa-Romeo...20906697255%26
reman I know you didn't want really but?
you just follow yanko and jsjtd for modding turbo inlet housing.
maybe some turbo specialist(adam are you reading?)?needs to offer a gtb2056 conversion with inlet compressor housing pre modified or a housing off another turbo that's a straight swap with a straight pipe in.
also pm toxic on here he has just had a turbo failure within 10mile not sure what he's doing with old turbo.

I think you are doubling money with the GTB1752v.
The GT2256v from 2.4 20v is quite a nice turbo and relatively cheap. It shouldn't lag that much with proper software. That seems a way better choice than any Audi/Merc/BMW turbo.

I thought the 10v 140/150 used GT2256v and the 20v used something else? I remember having a 20v turbo and it looked bigger than the 10v ones I also had at the time.

Both are GT2256v's. The 20v unit is a later generation one with a v-band connection and double wall at the turbine side.
Because of that the 20v turbine looks quite a bit bigger than its predecessors.

You won't need any fuel system changes until you get past about 200 road wheel power, so you'll easily smash through 200 fly wheel power. A simple hybrid of the GT1749MV can exceed what you are looking for with no loss of bottom end. bigger hybrids like mine can push out 2 bar or pressure by 2200rpm and they will need a fuel system upgrade to reach potential. If you go for a GTB you'll have to change a lot of stuff, if you go for a hybrid exchange, you'll just need to fit it and remap. If you are tight on money and only want 200bhp, it's a no brainer surely?

So noone thinks I've give in just yet, I haven't, I have instead been conned by a company called essexenginering services to the tune of over £400. Until I et this back I cant continue

Sad news, was that for a turbo or rebuild or unrelated to turbo?
