I was driving out in the woods the other day, and I see this subaru that had been shot at and wrecked. I look at the engine and I see a turbo off to one side. I just figured that it was no good so I left it. I tell one of my friends about it, and he says I should grab it, so I go out there and get it. Well, it turns out that the bearings are good and the it isnt too rusted or anything, and the fins on the impellers are in good shape ;D. The only thing that I have to do is remove a bolt that holds the housing over the exhaust side that broke off. What is a good way to remove a bolt if the easy out happens to not work(I havent tried it yet, but I have had this happen). I have been soaking it in wd 40 so I hope it works.

hey that sounds like you got a good deal haha, anyway, not too many posts about this or i havent found them, but does that turbo work well with the 1.6 8v?how hard is it to set up?
-
I am pretty sure it does. I think it is the same one that Wildgoody is using on his zook. On the subarus 1.8, it only makes like 4 psi and boosts the power from 90 to 110 hp, which really isnt alot. the turbo itself is a small IHI turbo, so it would make the most amount of power down low(where the trackick needs it). Not a bad deal at all, (free) as a turbo from the pick and pull is about 45 to 50 bucks.

i'm pretty new to these trucks(and in general homemade fabrication), but it would be great if you could detail the build process to turbo one of these trucks. I have a 1989 tracker 1.68v 5 speed, if its possible to boost the ponies without killing the inards/insides of the engine, besides that a properly functioning turbo makes a wicked sound!

That is the turbo I'm using right now, I think
the wastegate is set for 5-6 PSI, the Subaru
didn't have an intercooler, but I think you need
one even at low boost levels.
Now for the bad news, the 8V TBI engine needs
way more fuel than a TBI can supply, I'm running
a MegaSquirt aftermarket build it yourself MPEFI
unit, the only other thing I could ever come up with
to retain the stock ECU and still get enough fuel was
to drill the intake manifold and epoxy in injector bungs,
use some high Z 17-25 PPH injectors and wire them to the
stock ECU with a pressure switch that turns them on at
about 2 PSI (this is where the stock ECU fuel flow starts
to go lean) that would give you enough fuel to run boosted
but still have stock ECU drivability. 17 PPH injectors with the
stock ECU fuel flow was just barely enough flow, 20 to 25 PPH
would be better, but I don't know if the 20 or 25 PPH injectors
come in high Z (Ohms, high Z defined as 8-20 Ohms) so you might
overload the stock ECU and fry the drivers in the ECU.
Usaully the ECU grounds the injectors, you may have to add
a resistor pack or some other type of hardware, like a flyback
board, which is another ground point to take the load off of
the ECU, yet the ECU controls it, basicly it's a setup that has
high load capacity FETs, which are a special transistor designed
for high amp draw circuits.
ANYWAY
Great score

and now you need N.O.S? ;);D

NOS breaks stuff, I'll stick with forced induction

just kidding ;)

The stock ECU uses a darlington pair transistor which is a bit different to a FET. An resistor between the transistor emitter and ground provides current limiting and fault sensing so you're unlikely to fry it but unless you use a high Z injector or as Wild suggested a resistor inline with the injector then its unlikely that you will get enough current to power two injectors.

Weld a piece of metal to the bolt to use as a wrench.
