ok guys not being nasty so stop thinking like that, but after some research and some vids im wanting to go turbo... with that being said we have mass air meters, so is it better to leave it the cold side piping or try to run it with boost on it before the tb. and also what would be needed a bov or recirculating valve. i did search and its been mixed reviews or just confusing research. i plan on pushing maybe 7 to 8lbs max.

 

great title

 

i thought it would get some peoples attention

 

Yea I had to see what it was about

 

but for the question you got any idea's?

 

It's going to be much easier to just run it blow through. If you run it draw through it will run too lean unless your recirculate it into the intake. It's also much easier to tune because the MAF is closer to the TB, which gives a more accurate reading.

 

you got any pics of a blow thru on a 2.2? all ive seen is draw thrus and thats even on the hahn kit. but id take pics of how people rigged a recirculating valve up too. it just seems easier to do a draw thru tho

 

You can get a MAF tube on cobalt-addiction that you can use to attach your maf. It's pretty straight forward. You can mount it just about anywhere on the compressor piping, but it's best to keep it after the bov so that you get the right reading on the amount of air going to the TB.

 

lmao... didn't know what to expect in the thread lol

 

Why not simply get the Garrett kit? No thinking required.

 

well im wanting to put together my own kit and i was thinking that a draw thru would be easier since thats what the garrett kit is, but after some research i read up on the blow thru and now im trying to decide which route i should go

 

I would have to agree with halfcent, get the garrett kit. If you try to go custom it's going to cost you about the same, with more problems and headaches. Easier to install since everything fits like a glove.

 

bike boy my brother goes to weslyn of however thats spelled and ill be down there ina few days if you wanna meet up and check out my setup. i went from sc to turbo though but same basics. just pm me.

 

Blow thru Is your friend

 

so guys is the garrett kit blow thru or draw thru? see i dont guess i fully understand why one is better then the other anyone care to explain

 

The garrett kit is draw through, meaning it is on the actual intake side. The reason they can do this is because the bov recirculates the air back into the intake. If it was an atmospheric bov, meaning that it just blows out like normal, then it would run too RICH because the maf would sense a lot of air that would never see the manifold.

The garrett kit is specially designed for the draw through to work. Any custom jobs are going to end in nightmares for the tuners. That's why blow through is much more recommended. It makes the tune more reliable and stable.

 

how much boost is the wastegate in the garrett kit set up for im only lookin for 5-8psi and also is water/oil cooled or just straight oil because i thought their website said something bout water and oil lines

 

You mean rich...

 

Yup. Yeah definitely not be running lean, lol.

Don't ever come home and try to type after new years eve party.

 

so guys say if i wanted the garrett kit but only wanted like 5-6 psi could i turn it down or is it preset

 

Why would you only want 6psi when you can run the 8-9 or whatever it comes with? The motor can handle it... That would be a huge waste IMO.

 

There really is no need for that, but yes, you can. The exhaust by-pass valve on the turbo itself is adjustable. You can turn the boost up that way too. And if you use a boost controller, you can even vary the amount of boost from a control unit inside the car.

 

but i thought there were a ton of people that had this kit and it made like 250 whp and our rods were only good for that

 

Most of the dynos I've seen only show 200-230 with the set 8psi. If garrett made this kit for a stock cobalt, rest assured that it will be safe.
