Hey guys, so i just got a hahn stage 5 turbo swap for my lsj cobalt. I got it from a guy that never put it on since he sold his balt. No i am pretty mechanically inclined but havent dealt with many turbo systems and the installation instructions arent very detailed.

So thats the reason why i made this thread. Hopefully you guys can guide me though some glitches i have on the way.

Here is my cobalt as it stands

I already for the 2.4 tensioner and 2.2 belt, would the turbo from the zzp website for the turbo swap lsj be good?

Hahn should have hired me to write their instructions obviously.

soo oil pan is at the shop getting a fitting put in for the oil return line. Dont want to use the hahn method trough the drain plug cause i heard it leaks. Picked up new studs and bolts for the exhaust header cause some are rusted. PCM is at hahn getting the tune so i can drive it around for a while

She's almost done. Waiting for the PCM to come back from Hahn and missing a silicone coupler.

Nice. You'll love it. Best thing you could have done is turbo swap it!

Congrats, you should love it.

so cars running well, except there all this white crap all over the ground which sucks. It needs a tune tho. The a/f ratio bounces quite alot at idle but pulls strong.

Got a new clutch for it, since the stock one is still in it. Got a ACT 6 puck clutch kit from HopnDude here on the forum.

Looking to get a boost controller. What do you guys recommend?

Spend the money on one that you can tune in boost by gear.

Not necessarily saying buy this one, but it is one that offers such feature.

i've been looking for a boost by gear, but they arent as easy to find for our cars?
