You can run water cooled turbos without the water. Just make sure you run a good quality synthetic oil and leave your recir pump on for a couple minutes after shutdown. I would plumb a cooler in regardless though.

Got the new to me turbo. Has some side to side shaft play... but has not hit the housings so whatever. No front to back play. It is a td025m but has a larger compressor wheel. Not sure how this is going to affect anything... the exhaust side is the same though. I am going to get a new pump so I can put like 20-30 psi on the turbo for oil presure and I am going to redesign how the turbo is mounted probably, so I can have the carb. at the back inside the frame, I don't like it just hanging out right there lol. It's been raining here since I got the turbo and it suposed to rain for a couple more days I think. Maybe one day it won't rain where I can work on something. lol
This sounds like a really fun project. I wish I knew about turbo's b/c I would definitely like to play with this setup. Keep us posted!
You should get some videos up of this thing. It seems sweet.
Sorry to hear about the turbo nuking. You will have it back together.

im working on a turbo set up also. ive read this whole post and everything sounds good but im gonna run a blow through set up! we will see if it makes a difference or not. i may also intercool and put a blow-off on mine. The main point of a blow off is to stop the wheel from spinning making it easier on the turbo. anyway, did u ever put a fuel pump on yours? and what type of oil pump did u rig up to yours? did u use the existing oil pump wiring?
You are very uneducated on how turbochargers and the related plumbing works. A BOV does NOT 'stop' the compressor wheel spinning.
What a BOV does do is when the throttle closes suddenly (like during a shift) all the volume of air that the compressor is pumping has no where to go, and there is a slight vacuum on the one the engine side of the carb. A BOV releases the pressure by sensing the differential across the throttle plate.
If that pressurized air does NOT get released the pressure wave will bounce off the throttle plate and back feed to the turbo charger's compressor causing it to surge and stall (make a chuffing sound.) This is bad. It eats your thrust bearings in the turbo and on some of the larger turbos, can throw blades. (I have seen this happen.)
On another note, I know that you just can't take a carb and blow thru it. You'll need a carb that is set up for it. How to do this, I really have no clue.
Blow thru, you can run an intercooler, but the IC needs to be before the carb. if you use a draw thru carb with a intercooler, you'll have pooling in the intercooler.
Fuel + hot air in the intercooler can lead to a bang.
That all being said, best of luck with your turbo projects. I might try my own some day when I can afford another bike for my 14 y/o to ride and the Blaster is sitting again.
that is very correct. i know a lot about turbos and turbo systems! i left out the part like it will stop the turbo from decelerating too quickly aka stopping the "pressure!" not the wheel from spinning! sorry next time i will be more thorough and write 5 paragraphs 8-| just kidding man! but! you can do a blow through but you have to have a fuel pump and lower the afr so you will run rich until in boost!!
plumbing the intercooler would be difficult because there is simply a lack of space... so my goal will be to find a very small intercooler to plumb in line between turbo and carb WHICH IS THE WAY ALL INTERCOOLERS ARE PLUMBED (without risking injury) but to solve this issue i could also do meth injection to cool the air without the intercooler sir! soooo think about that

I think you guys are gonna need alot of pistons, you had better pressurize the float bowl so its equal to the pressure of the turbo, I would re-cut the piston for lower compression and if you are gonna attempt this EGT is mandatory, if you dont have the funds then dont do the project, that set-up is crude to say the least like hp said I also seen Vitos blaster in SC and it was interesting to say the least, I talked to a couple of the guys there and they were nice to deal with and the blaster was very nice, I don't understand the blaster though as who to race I think banshees are the way to go.
were's this project at now? how about a update or if it's dead in the water then say so, i'm sure hopin it's out there somewere yet, or if anyone else has a project like this lets hear about it
I know Im new here but Im a total turbo car geek. I own a 91 Mr2 turbo thats pretty modified.
Anyway, a question. You say the turbo is BEHIND the carb, meaning turbo draws air in from the carb itself. That means the air the turbo is taking in has fuel in it right? I see an issue with that, as the fuel in there will eventually (sooner than later) chew up your seals and blow your turbo. Another problem with this is the fuel will cause pitting and eventual damage to the compressor wheel and the axial shaft.
This is very interesting to me though. I will be following this thread.

I never said it doesnt work. Heres a link from one of your VW boys talking about the 2 different types of seals in turbos.

"Word to the wise: There are two different types of seals in turbochargers: dynamic (aka piston) and carbon (aka positive). The carbon seal is suitable for either blow-through or draw-through applications. Dynamic seals are suitable for blow-through only! I repeat, you cannot use a dynamic seal on a draw-through turbo system. This is important. Ideally, you would select a turbocharger that came with a carbon seal already in it, and save youself a lot of headaches later. Unfortunately, carbon seal turbos are a rarity, because the newer dynamic seal is more efficient, and well suitable to the fuel injected engines that are used these days. So, the moral of the story is if you want a draw-through setup, either a) find a turbo with a carbon seal, or b) rebuild your turbo and convert it to carbon seal."
