I do not want to use a "regular turbo" those are for fanboys and weak minded storm troopers *star-wars joke* I want a challenge and I want the benefits thereof. ;) I want either a vgt, or vnt, but every time I search I get these huge holset deals from 6.0L and up or nothing but porn. So how bout it folks, can I even get one of these and if I can where from? I want to have boost at low speed, but because of the monster under the hood that demands more boost "in the department of 30+" I need something that still has kick in the top end too for diesels. Oh, and I also cannot continue my build without information such as which turbo? which exhaust manifold? which intake? intercooler and piping options? oil cooling and lines? egt guages and psi/boost guages? and so many more important factors rely on the correct selection of the turbo for my particular build. Can anyone help? I have used the search and found some euro garret turbos, however, as best as my google magic tells me these cannot be found in the states. Someone please prove me wrong :'(
thanks guys, and happy holidays,

I have also looked into supercharging options, they seem very promising low lag constant power throughout the powerband but I would really like to try one of the VGT/VNT's I personally have never used one before, and would love to have the first hand experience.
-
Both?

HMMMMMM..... *ponders* as awesome as that sounds, to run a turbo and a superchargerI'll prolly have to go with either the vnt 20 or something bigger in a twin setup. thanks guys, and turbogreasel I wasn't aware that there was freedom in CA? I thought all of the liberals took care of that all ready? JK
-
my VNT 17 was way more than enough air... but if you are going balls out, you need something bigger. you can probably get about 160 horse out of a VNT 17.

careful big guy or they will get a court order to think for you

It's all custom stuff unless you buy a very pricey new turbo from kerma or tdiparts (around $1500) . I recently bought a brand new vnt25 for $200. It's definitely on the big side and there's a lot of mods I need to do to get it to fit but it shows it is possible to find something for cheap. Your best bet is to keep checking the euro ebays for a good deal.
-
Check the build thread, I definitely want the twin setup, already doing research the setup is going to be a challenge *giggles with glee* thanks for all of the help, I'm thinking a 15 coupled with a 20 for maximization of low end and high end power, with the giles pump this baby is gonna scream.

Actually, the damn conservatives made us rename 'Whiskey Hill' (http://planetsmilies.net/eat-drink-smiley-5170.gif)

Probably with gt1749vb, but never with gt1749v. 17 series are used in 90-150hp tdi:s from factory. gt2052v from 2,5 V6 will spool alone just fine and is good to ~180hp.

17/22 hybrid. ;D
-
17/22 hybrid sounds pretty good, anything I need to know? too much boost, melted pistons, warped heads, and bent rods doesn't sound like my neighborhood :'( what kind of results can I exspect from this, anyone done it? the twin turbo setup is pretty much shot down :-[
-
17/22 will flow more and spool faster than a 17.
-
go with a K24 or K26. .or a mercedes 300 diesel turbo. Josh is running one and really likes it.
-
Yes, a K24 turbo and running 44psi. I know, I know, its not good for it, but its not boosted for more than maybe 2-3 seconds. So far so good. I will be using the Mec. T3 turbo on the drag engine.
-
While on the topic of turbo sizes etc, anyone know much about the t3's from bmw e28 524td?
Specs are as follows:
A/R of the turbine is 0.36 and the A/R of the compressor is 0.48. Also, the compressor is a 50 trim wheel with a 42.2mm inducer and 60mm exducer.
To big, small, laggy? I can't find a compressor map.

holy hell, 44 psi? intercoolerd or not? im just getting ready to put a K24 on my 1.5. you wanna race one of these days josh? and how bout that timing gauge? still let me time my car if i come up there? i need to reseal my pump and put a new timing belt on there.
-
the question remains, is all of that boost useable? can I still have good power on the start when does it start spooling?
-
my K24 started spooling at about 2000 rpms once i put the boost controller on it.
-
hmmmm not too shabby :)
-
ok, what is the more common name for the k24? so I can find it.
-
KKK K24 ???
-
so the descizion is between a 16/22 hybrid and a 24? which is better I can run lots of boost as my static comp rat. is 17.5/1 with 1.6 l of displ. I need to get a little more input on this from the experts before I do some buying research and actually get one. Shoot, I may just get both and try one and then try the other, anyone wanna let me borrow theirs? :P

I don't think it's anywere near 17.5/1 CR, it would be a PAIN to start being IDI and all.
-
check my build page, it will be about 17.5/1 static comp...... and yes, I do know that it will be a pain to start in the mornings, block heater anyone?

I forgot if are you doing 1.6 block, 1.5 crank rods and stuff with a 1.9 head, or if you decided to use all 1.6 bottom end stuff and a 1.9 head. I was thinkin' 1.6 bottom and 1.9 head.
-
yup, sorry bout that, the label should prolly change then huh? How about the k24 coupled with a supercharger setup? I think that the best for the low to high is going to be the 16/24 hybrid, however, if I want to have my cake and eat it too then I will need an exotic setup. I will have to look at the S/C options for this, I have seen twin charger setups before, mine will have to be a little different. I will have to use meth injection to keep egt's down. Hmmmmmm. C02 cooled intercoler......... yeah, that would work pretty good but be exspensive :o I think that FOR NOW, that the 16/22 hybrid will work best for my purposes and later down the road I'll upgrade to the S/C meth inj. and C02 spray method.

if you are looking for a vnt 16/22 or 16/24 hybrid, you will be looking for a long, long time. i think ive seen VNT17/20 hybrids tho. heres a way to look at it, a VNT is going to be very expensive, and very complicated to get the vaines working properly. or you could go with a normal turbo, it would be much cheaper, and much simpler.
and i thought we already went over this, didnt your engine come out to have like 15 or 16 to 1 compression? your engine is not going to run right with that little compression. your dropping almost 10 points of compression from stock 24.5 to 1. the air in an IDI diesel has to be VERY VERY hot to fire the diesel when its cold. just rebuild your 1.6 bottom end and throw the 1.9 head on it. it should be perfect. didnt you say that motor has almost no wear anyway?
-
I am running the 1.6 bottom end, that's why I said that I said that I should change the title, because it is deceptive the vnt is better because of the early"er" bottom end response I am willing to spend the dough, it is worth it to me. still looking for info on the rover boost pin too. line bore and hone and I'm having it hot tanked too for good measure "I want to paint it"

i would just look it over, it may not need to be rebuilt. thats fixing something that aint broke. thats not cool. and you still have to figure out how to control the vains of the turbo, you dont just bolt on a VNT and have it work. it needs a fairly complex control system. try doing a search on how some people have controlled their turbos. some of the builds are super complicated.
-
I DO! electronics, it's my thing "along with H/V tesla coils" so a VNT controller shouldn't be that difficult
-
I have a garrett...... well, something, just sitting around in my garage, was told is off of a JDM 180sx "spent a few years there" any good for our cars? worth the rebuilding? hybrid ideas? garage sale the bugger? Got pics?:

has bad seals and needs a rebuild "can't for the life of me get the darn thing apart" other than that has no shaft play, just leaks on the exhaust side. I tested it with a shop vac and some wd-40 in the oil journal "cleaned all of the gunk outta there pretty darned good it did" I want to send it to gpopshop but they are dman exspensive I want to just do a rebuild and get them to balance it for me. Maybe do a port job "those are a PITA" any thoughts on this thing? not a vnt but some here favor away from the vnt route.
-
the VNT route is the way to go if you want to complicate things and have to possibly build an electronic controller. a normal turbo requires no other modification really. just pipe exhaust into it, and pipe the boost into the engine, voila. you can use a VNT for an exhaust brake also. theres lots of high points with a VNT turbo, its just damn hard to make them work right on an engine that has no setup for running any electronics.
besides, that tiny little turbo you got might do just fine. probably not gonna build no 30 psi, but its a start in the right direction.
