Smallest single turbo on a type 1 1600?

[woodsbuggy]

What is the smallest single turbo you have used on a 1600? When did it start making boost? How much boost?
I want to build boost in 1st gear, I do not want to rev past 5k, and I only want 8lbs of boost. This will be in my sandrail, mainly running trails and climbing hills, we spend 90% of our time in 1st gear. I do not want to build a turbo system that doesn't work for my application. I have several turbos, and more available.
Thanks

I dont personally know, I went with a T3 and its the only one I ever used. Seems that from my reading, a T25 (Mitsu) is as quick spooling as they get.

What's up, buddy?

If you want a 1600 with instaspool, I have a tiny IHI from a European Diesel sitting in my garage? Looks like a Briggs motor might be right for it, you interested? The model is VL20.

I have used Garret GT1544. In 4 gear i had 0.5bar at 2200rpm. Good turbo for extra torq but littlebit to small for max hp readings.

These turbos you can find from different small European diesels like Vw, audi and opel. (1.4-1.9 TD)

Here i have dynoshart with turbo like this.
Lower hp reading is with single port heads and 30pic solex carb. If i remember right the boost was around 0.8bar
Higher rpm reading is also with 1600cc but with dual port heads, dual dellorto 45 and with an intercooler. Boost around 1bar (carbs not properly tuned )

Hp reading is real wheel power not calculated engine reading. If you want to calculate engine reading ad 12-15%

Thanks for the info. I have a couple T3's and a TDO4 12T from a 3cyl diesel tractor. I think that the TDO4 is what I want to run on my offroad machine. My street rail will get a T3. Nick great to hear from you , I always look for your input, you have a PM.
Thanks

i have just put a KKK K-14 from a Vanagon 1,6 diesel on my stock 1600 DP engine.
0.7bar boost so far up to valvefloat at 5200rpm
this is a puny turbo and have full boost at 2600 (in 4.thgear) but i have som tuning left to with the timing as it is just locked at a low setting
more timing in the lower RPM's i hope will spool it up quicker

My KKK K03 starts boosting at around 2,500rpm and is done by 5,200rpm. I'm running 10lbs of boost on my 1600. A K03 is pretty instaboost, it's a tiny turbo and it works well on a stock 1600. They're commonly available as well. It builds boost in 1st gear just fine.

[woodsbuggy]

That is what I was wanting to hear.
jweir, What vehicle did your K03 come from? That sounds like what I am looking for.
Fastback, are you sure that your valves are floating at 5k? My heads were rebuilt 2 years with new factory German springs and I have seen 7k on my motor several times. Could the turbo be limiting your RPM? My current motor is NA with a modified 34 Pict carb.
Has anyone seen a chart or ? that compares turbos from various brands by size? I am somewhat familiar with Mitisu and Garret turbos but do not know how thay compare to other turbos by size.
Thanks Again YOU GUYS ROCK!

find a K03 from a vw or audi 1.8T, golf or A4. A K03 is one of the smallest on the market. points bouncing can seem like valve float, stock points float at 4,500rpm, so get bosch points #01030, good for 7k. My setup starts rapidly loosing power after 5,400rpm, so no need for a rev limiter. I take my buggy mostly on trails, and the powerband is great, no noticable lag and full spool up at about 2600-2800rpm. It'll putt around great and it's got the power on tap when you need it. It's probably got 110hp? 34pict3 blowthrough and modified stock fuel pump runnin 10psi. cheap and it works great.

[fastback]

my engine is a very high miler
so i asume the valve springs have been stiffer
it's just a cheap'O pilot project using a well used , bone stock 1600.
and i used leftovers vanagon exhaust pipes for header etc.
i have vanagon distributor with hall sensor.
and for the moment using megasquirt EFI, but also run Digijet from euro vangon on it
running E-85

a loto of fun as it pulls pretty good.
will get a dyno as soon as i have mounted DIY waterinjection and added more boost

I finally scored a K03! Please forgive my ignorance, but can I rotate the compressor housing to make this easier to mount? I realize that I will need to fab a new wastegate bracket. I was hoping that I could just loosen the bolts and rotate it. The shaft has very minimal play so I thing it is safe to run.
Fastback did you make it to the dyno yet?
Thanks

Congradulations! The stock wastegate bracket has to stay put. You can rotate the compressor housing around clockwise to the next set of bolts and leave the wastegate bracket where it is, but I don't think that's going to give you a better position. You really only have 4 positions that way.I did loosen the bolts on the center cartridge and took the compressor housing off and rotated the center cartridge to get the oil drain and feed in the proper location, that gives you a little room to work with when trying to figure out how to mount the exhaust and intake. What kind of KO3 did you get? The one from a 1.8t or a 2.7t? I just scored 3 more KO3's from my buddy at the audi dealer for $100 (2 2.7t's and 1 1.8t). They were in much better condition than the one I have now, so I'm swapping mine out for a better one.

welll if you end out really happy with that turbo let me know, I spent quite a while trying to find the exact same idea, early mild boost on a small engine for woods running!

[woodsbuggy]

jweir,
Thanks for your help, the one I have is from a 1.8 found it for $30. I am interested in more info on your build, one of my friends wants to blow thru a 34.
fusername,
I will keep you informed on how this works out. Several of my friends are building larger engines, so I will need more power to keep up. I am hoping that this will do the job.
Thanks Again

No not yet, but DIY waterinjection is mounted.
and i need larger injectors as the duty cycle is on max.
...and there is almost 1.5 meters og snow here and average temps around 0 F last months so things go a bit slow
