mercades c250 gt20 - padge - 16-12-2013
got one of these, but cant find out the exact size, 2052/54/56? tried a few turbo sites trying to find it but nothing really about, anyone know the size?
RE: mercades c250 gt20 - Chris - 16-12-2013
The c220s are 52s so could either be the same or a 56?
RE: mercades c250 gt20 - padge - 16-12-2013
on one site, it said they come with a gt25C, but I think that's a twin turbo one? that's what it said anyway, but mine was listed as a GT20.
RE: mercades c250 gt20 - Craigus - 16-12-2013
All i could find about c250's is they have either gt20, gt20c or gt25c...
RE: mercades c250 gt20 - Ruan - 16-12-2013
Gt25c is a 52mm but old style turbine wheel iirc... So has a t series turbine and gt series 52mm compressor.
That's before they went to the new GTXXYYZZZ naming scheme, so GT25 means nothing.
RE: mercades c250 gt20 - padge - 16-12-2013
so what would those be like on an xud? I could of had one for £99 but decided against it and got the gt20 instead, much difference between a 52 and a 56?
RE: mercades c250 gt20 - Fezza_rs - 30-12-2013
Run a touch higher boost with a 56, 52's die over 25psi as the shafts on them are too thin for any more stress.
RE: mercades c250 gt20 - Piggy - 30-12-2013
56s die too...just ask pellowe
the mercs after the the early gt25s are gt2052s
£99 is around average of what I have seen on the bay...seem some as cheap as £75

don't forget about flow, standard t2 might do 20 psi+ but it wont flow anywhere near as much as this thing at 14 even.

I rekon by the difference the T2 on Ozones xud11 compared to my GT2056s, it flows twice as well, and gets on boost sooner too...and then continues to flow once the T2 is out of puff, which is quite soon even at 30psi
RE: mercades c250 gt20 - Anton - 30-12-2013
My gt2052 flows more at 5-7psi than a t2 does at 20psi
RE: mercades c250 gt20 - padge - 31-12-2013
anton, whats yours go like? and when does it hit full boost?
and whats your clutch hold like?
RE: mercades c250 gt20 - Anton - 31-12-2013
Hitting 20psi just over 2k. 25-27 by 2.2k. Clutch has held fine. Standard valeo with about 15k miles on it, now about 25k.
RE: mercades c250 gt20 - Piggy - 31-12-2013
Im on standard valeo too with the 2.1 n gt2056... No hint of slip yet
RE: mercades c250 gt20 - padge - 31-12-2013
Ahh, more confidence now then thanks.
RE: mercades c250 gt20 - Chris_90 - 31-12-2013
Think we need some dyno results off people running this turbo, to see what its capable of?? unless ive missed some ones results?
I no ruans but that was vnt, whos done one with the non vnt one?
RE: mercades c250 gt20 - Piggy - 31-12-2013
I think ruans was a 1752?
I may go for a run in Feb, once back off holiday and earnt some dollar

No he had a gt20v under his sig ( Black GT20V XUD9TE 306 Ph2 DT - Sorely Missed. )
Sure it pulled in the 300ftlbs of toque, but guessing you guys haven't got that kind of toque cos you would be slipping the clutch by now? Or am i wrong
RE: mercades c250 gt20 - padge - 31-12-2013
As soon as mines on ill do a dyno run
RE: mercades c250 gt20 - Tom - 31-12-2013
Yeah Ruans was a gt2052v and he is the only person so make 300ftlb in an xud, well im sure he was the first someone might have beat him by now!
I think he put a gt17v in the moonstone thingy.
RE: mercades c250 gt20 - padge - 31-12-2013
Jp was the first i think.
RE: mercades c250 gt20 - Chris_90 - 31-12-2013
I really would like mega toque, starting to be put off by the gt2052 now
RE: mercades c250 gt20 - padge - 31-12-2013
Gt2052 should make good torque tbh
RE: mercades c250 gt20 - Piggy - 01-01-2014
You'll get more torque from a gt20 than a td04 all day long

Surely not more? Maybe sooner in the rev range, and sustained for longer.

Power equals torque/RPM..
TD04 will pretty much always make less torque, go look at the figures...
My black DT had a GT2052v on... Made 313lb.ft torque.. My blue DT had a GT17s from James Aston with a screwed up hotside...
RE: mercades c250 gt20 - padge - 01-01-2014
yeah the gt should near enough always make more torque than a td04.
RE: mercades c250 gt20 - rryan - 01-01-2014
i got one one of these a couple of months ago, and just got round to mating it up with a manifold, and adaping a td04 actator to fit. i will get some pictures up.
how were you going to do the exhaust side? ive got a 3" elbow and flexi and i was thinking of getting a v-clamp and making a flange to weld on to the elbow, instaed of just welding the elbow the hotside
RE: mercades c250 gt20 - Ruan - 02-01-2014
Oh you're in Bicester?! I'm just in Kirtlington... We should meet up at some point..
Take a look at Rickys project thread, he used one also, used a v-band welded to an elbow, it's the way forwards as you can set the angle easier, otherwise you'll set it slightly off and it'll be under strain 24/7!!
RE: mercades c250 gt20 - Piggy - 02-01-2014
Bicester...just down road from me too...be curious to see how you get on
