took a ride in exist3nce's turbo optra

what a fun weekend, as some of you might know im moding my buddies 2004 optra (forenza for you US guys), and exist3nce offered us his apexi springs, so we drove to the street racing capital of Canada, and took a ride in the beast. its was snowing, about -3 degrees C, and the turbo optra had its summer shoes on, anyways hiting around 180kph (his car is in miles so we toched about 115) at about 10 psi. the car is very clean, and smooth. i had a video but it came out like ****, so only pics.

i want to turbo my aveo now :oops:

the intake filter is a screen? bad idea!

its the compressor side of the turbo, so items dont get in and mess up the blades.

But it does not stop the dirt. Not to mention it draws in hot air from under the hood.

oh I see what you mean now, no filter off of the turbo, yeah hopefully thats next on the list, although I have seen screens over the turbo in magazine's before

there are a lot of people that believe if there is something light enough to become air born, yet small enough to fit through the screen like on a screen door. it will not be able to harm your engine. as dirt particles flow through it normally anyhow, theoretically.

but i dont think i would take any chances on a car built sine the 80's. specs have become tighter, aluminum is soft. and tolerances on an impeller for a turbo are crazy tight.. maybe if you have a pinto, or flathead v8 you could reason like that.

Good luck with the cold side wheel. I have first hand experience with crappy filters and turbine wheels with my diesel, a little over a month with a K&N and it ruined a wheel because the turbo would suck the oil out of the filter (I'm pushing 40psi+) and let fine particles though, putting nicks in the blades. With that screen and this time of year with the city laying salt and sand down, your going to kill the motor along with the compressor side of the turbo.

The other thing I see is the crank case vent going to the mouth of the comp housing, weld a bung into the stainless tube and send it there. You don't need the oil being sent though the housing.

It would just seem like common sense that any air being pushed into an engine should be filtered and a screen is not a filter.

You dont want to do that because it will pressurize the crankcase under boost.

im sure he knows what he is doing

yeh, his car has been boosted for 2-3 years now with only having to replace the motor once(?) he knows the risks hes takin... this car is beast for what it is.


i myself would throw a filter on there right away, but as it was said, hes workin on it. he has a whole thread on daewootech for his car.

True, wasn't thinking when I wrote that.

The PCV valve is a one way check valve, only letting air out of the crank case....but I still wouldn't put it on the piping.

you would be surprised how often a PCV valve sticks open.

True, which is why they're supposed to be inspected ever 50,000 km.

Just out of curiosity, does anyone know what kinda times it runs?

i beleive its in here somewhere, but theres 39 pages and i aint gonna read em all for ya. peace.

that run was on low boost i believe, he puts out more power now days

He claims he can slightly beat his friend's mazdaspeed 3 on the 1/4 mile, which is slightly modified, so his optra is pretty fast and that was a while ago, might be even faster now, imo hes running low 14's maybe high 13's, im sure he cant wait to post up to date times next summer when his 1/4 mile track re-opens.

39 pages huh. It isnt that important. :lol:

:shock: I don't know but it seems if I am going to spend that kinda money on a car I would spring for the best filter to use on a boosted application
