1852 turbo or vnt-20

[Crazy Memphis]

how would you guys compare the 1852 to the vnt-20. for a jetta 2000 alh. both from kerma. i have been told that the 1852 was bigger then the vnt-20.

how long is it for the installation

 

[Crazy Memphis]

i just ordered the 1852 from kerma and i just wanted to know if i did the right thing.


OKKK ya i know it's much better then a vnt-15 ya ya ok but. but i just want to know if it's really that good or if i just bought this on a knock of the head !

it was the only one he had in stock that he could send me before friday and that i could install before the tdi fest !!!

is bigger better ... some girl says yes some says that it only need to be fast ... but i ain't a girl so i don't know

some girl advise lol !!!

I have heard that the 1852 is a bit better than the vnt-20. My understanding is that on the vnt-20 with ST3 is capable of more HP but takes longer to spin up and usable power band is higher in the RPM range.

My 1852 left Kerma today and should be here tomorrow. Hopefully, my car will be running again by the weekend... although, I'll be sad to see the Aveo rental go

1852 is a great turbo u will be happy

 

[Crazy Memphis]

the vnt-20 is capable of 250hp and more. what is the 1852 capable of ???

is it better in the low rev or high rev ???

do you have boost until 5000rpm like the vnt-20 or it's 4200 like the vnt-15 and 17 ???

how long does it take to install the everything ???

do you need a lift and a lot of wrenching skill or just a jack and some experience ???

 

[ibanix]

You're going to need a new ECU tune to use that effectively.

And man, get a boostvalve on there while you are at it, so you don't blow a turbo again.

 

[Crazy Memphis]

there ain't much description on the 1852 on this site. hmmm

i only found one thread that mention it lol .... i thought i knew how to search but if you can help out ....

any spec or detail ... anything


i think i am talking alone or to myself..... PM me if i start answering myself ok !!!

 

[ibanix]

I don't really see the '1852' listed there, I assume this means a vnt-17 with the 52mm compressor option:

[ibanix]

Ok, I guess not - the 1852 is apprently a gt1852 which is made to fit into a vnt-15 housing...

 

[buckweat diesel]

tune comes with turbo

if you have never put a turbo in it takes some time
you should be ok

i can walk u through it over the phone

 

[Crazy Memphis]

ya but it's supposed to be bigger then the vnt-20 does it mean that it is better ??

Can I drive to portland and get you to help?

Just funny because I might be in Portland this weekend

It's not the size, it's how you use it!

i have my kid this weekend
but im glad to help when i can

 

[joevat]

My understanding is that on the vnt-20 with ST3 takes longer to spin up.

what a load of crap this is. this vnt20 st3 i got spools so friggin fast. at first i was easily shooting 36 psi in less than 1 sec. the understanding is that people think it spools slower cuz of a bigger size. but actually it comes down to tuning. alligator does an amazing job tuning these turbos. i really gotta take a little vid of how fast this thing spools. i took LNXGUY out for a ride and he was laughing hysterically how fast it spools.

 

[buckweat diesel]

if they are tuned right they do work well

 

[ibanix]

i have my kid this weekend
but im glad to help when i can

I might take you up on that one day

 

[Crazy Memphis]

joevat ... Paul and Charlie just told me that the gt1852 i just ordered was bigger then the vnt-20. i knew the vnt-20 was awsome on the spool because of the size but the spool of a turbo is mostly due to the 52mm compressor. but correct me if im wrong but does the 52 in1852 mean 52mm compressor ???

from what you are saying and what i can read ... the difference between both is that the 1852 is a bolt on with the same strenght as the vnt-20 but it have a smaller flange (stock size) then the vnt-20.

does it mean that the gt1852 could hold up the same hp then the vnt-20 ??? that's mostly what i would like to know. cuz i don't wanna change turbo in 1-2 years cuz i am to advance in modification and that the turbo is now to small !!!

but that's to late it's already in the air lol !!!!

CAN'T WAIT TO INSTALL IT

According to turbo international, the compressor wheels for the VNT1852 and the GT20 are the same. I havn't found the turbine wheel sizes, but I'd be willing to wager that the 20 has a larger turbine wheel.

 

[StingrayRT]

second generation turbos from garrett has been very powerfull eg. compressor wheel coating, new vanes design......

 

[hatemi]

Both are good for 200hp. 210-220 if your realy pushing it not caring how long it will last. I dont know what wheels the ST3 has, but I'm pretty sure it has a very decent combo in it. Might be something like 42mm turbine and 56mm exducer compressor wihch will spool silly fast and can deliver around 230hp. There are better turbine housings around than the VNT20 for a hybrid tough

 

[Doc_Oc]

So, you're saying that the VNT20 is good for only 220?

 

[Scott_DeWitt]

joevat but correct me if im wrong but does the 52 in1852 mean 52mm compressor ???

Correct per garrett's naming convention the last 2 digits correspond to the compressor wheel. Supposedly all GT18s and vnt18 have the same turbine diameter, but there are more exceptions than rules to this.

This thing spools no slower then my vnt15.. So I dunno where people are getting there stats from.. Zero issue's with spool up on the ST3.

 

[hatemi]

If your pushing it... It is small. As simlple as that. 200 is safe. 180 is relateivey safe with VNT17. You could push it further but it wont last in the long run. With hybridized versions you can go anywhere...Or at least further than most are going.


Not me tough

does that mean that vnt-20 is 200hp vnt-17 is 180hp and gt1852 is 190 but can go higher cuz it's a hybrid ??? if that's so how high do you guys think it could go !!!

could the gt1852v perhaps be like the vnt-20, but the vnt-20 spool later in the rev compared to gt1852v ???

I just installed the 1852 in my car a couple of weeks ago and its seems better but I am still waiting for Tech9 to re-tune my car for it, I hope they can do it soon because limp mode is making me mad.

 

[LNXGUY]

You need the supporting mods to go along with the turbo if you want to make some big power (11mm pump, giant nozzles, etc etc)

 

[hatemi]

I meant that both VNT20 and that gt1852v can go to 200hp pretty safely. You can get bigger wheels inside the VNT20 housing to make it support more but then again its not a VNT20 anymore at that point

 

[Fox_Kid_263]

Would you guys recommend R520s over PP764s with the 1852? I am just wondering because I don' t want to get PP764s and then want more power and have to get R520s.
