Aveo turbo charging & part options

[Wolfman AK907]

Yeah, I think the K04's came on the Audi's? I might be wrong on that though....

[petrified.rabbit]

general rule is ko3 is on the 150 hp, ko3s is on the 180, and the ko4 is in the 225 audi TT and Sline A3 (non US market).

There is some overlap with the ko3 and the ko3s though, buy one? engine code.

either way depending on how you were setting up the engine any of the 3 would work, the ko3s is probably the best of the three (in my opinion) for the aveo 1.6, But if you are going to put our own turbo kit together, and buying a new turbo, i would go for ball bearing v-clamp , or some other design turbo. I would have no issue over using the ko3s though.

It's a good starting point if you think you might want to upgrade later. In my opinion anyways.

I'd like to keep the ideas flowing here.

I was looking at things last night. I had my engine on the stand, so I set the head on it real quick, bolted the oil pan back up, and thew the exhaust manifold on. I just so happen to have a T25 off an eclipse laying around that I ended up not using on another project. I don't see any reason why that thing couldn't be bolted right up to the stock exhaust manifold with a ~1" adapter plate between. This would make for an extremely cheap turbo manifold. And, IMO the stock manifold is a pretty nice piece. I inspected it to find no casting flash or any obstructions that would impede flow. I was pleasantly surprised. I can't speak for the ecotec engines, but this was the case with my etec.

The problem I did see is that if you have AC, there would be no room for the exhaust piping. In this case, you'd probably need an aftermarket manifold to move the turbo to the driver's side more to get some clearance.

I'll try to get some pics of what I'm talking about so this makes a little more sense.

One of the bigger problems with turboing an Aveo is the position of the oil filter there in the front...it's kinda in the way.

I don't recall the filter being in the way. Of course it was not on the block when I checked I don't think, haha. I'll check that out though. If it is in the way you could always get a relocation kit.

there are filter relocation kits and if i recall correctly they are only $20-40

Alright, I got some pics. I was able to thread in one bolt to the turbo flange, but I used wire and a block of wood to kind of position the turbo close to where it would be. You can see its off, but not by much.








Looks like the turbo may need to be clocked a bit. No biggie there.




The only concern I have is that the oil drain back will be too low at this point. You can see the slope of the oil pan which I assume is level when the engine is in the car. This doesn't leave a ton of vertical distance for the drain back.



I did check, the oil filter has more than enough room to unscrew. It only comes out about 1/2 to 3/4" before you can remove it.

Never mind turboing the Aveo... is that a Jaguar I see outside the garage in one of those pics!??

V12 Aveo!!

[Daox]

lol, the V12 is about as long as the entire Aveo. :P

(BTW, yes, in the way background in the 4th pic is my 1973 XJ12)
