Yeah ill stick to driving it around in vacuum for 1k miles. lol Hmm, maybe i can pay someone to do it for me while im at work, but i dont think i trust anyone but kevin to drive my car.

 

why is that, cause i jumped in it and drove it like i stole it! lol! nah i just know if i blow it up then i replace the motor heck i would drive that little beast around i am cool with that!

 

I hope that the smt/ECM will not freak out that I have my cat-back and run all funny on me.....

 

It doesnt care about the exhaust. It just cares about how much boost is going into the engine. you will be fine, just make sure you know how much boost your pushing =P

 

I already have my boost gauge/controller connected.

If it does not car about exhaust, then hoe come you blew your intake mani after your's was put on.... Did you crank up the boost?

 

1 of 2 things. When i inspected my engine bay just after it happened, i noticed the line from the outlet side of the turbo that feeds into the wastegate actuator had come loose and was hanging. but once i fixed my intake manifold and watched my boost gauge after plugging it back in, it would still overboost, so i believe the actuator/wastegate is stuck. the guy working on my engine right now is taking a look at it.

 

I see. I will make sure to really secure those lines then.

Why/How do you think the actuator got stuck?

 

Honestly im not sure, all i know is when i hooked the hose back up it was still overboosting, making me believe the wastegate or actuator wasnt opening. we will know by tonight whats up cuz hes spending all day today on my motor. only problem is i dont have the parts in yet, so its gonna be next week sometime that he puts it back together.

Im also only able to get 9.5:1 pistons from Diamon Racing for the L61. Whats weird is they have Ecotec 2.2 pistons, but the engine code they show is LSJ. The only L42/L61 pistons they have that wouldnt be custom made are 9.5:1. I was hoping to up the compression to 10.5:1 but it would cost $480 for pistons. The 9.5:1 are going for $371 bux, not including rings, but those shouldnt be too pricey i hope. So ill be running 9.5:1 compression, @ 15-20psi.

Trevor, since you did those calculations with the compressor map, can you see what 15, 17, and 20psi would do on that map? See if its doable. If you do that for me, ill let you drive my car =P and ill help you tune your car if you need it, since ill have experience tuning mine at high and low boost levels.

 

I will get to work on that. May take a bit since I will be working on my turbo....

Hey, did you have any gasket's with your kit?

The instructions says that there is to be two. One between the turbo and the manifold....




and the other between the exhaust side of the turbo and the elbow:



John said that the surfaces are machined so that you do not need the gaskets. Just want to see what you got in yours.....

 

I cant see your pics right now, i will when i get home. i know there is supposed to be a gasket between the turbo and the manifold. By elbow, do you mean downpipe? the piece that mounts to the exhaust side of the turbo that connects the turbo to the stock exhaust pipe? I dont believe i have a gasket for that, but i also dont have my car handy to look right now.

 

should always use a gasket...also did you get t-clamps? if not ditch the ones that came with teh kit and go get some...hmmm lemme think what else.also look into a way to turn the fan on with the car being off..ie a switch with that going to a power source..does a couple of things..you will basically have no heat soak when dynoing or at the track

btw thats looks almost like a 60 ttrim turbo

 

you guys gotta stop quoting pictures so much lol

 

Nope, 55 trim

 

55 trim lol wtf

 

from the dead!!!!!

Sway....did you ever get your motor back in to that dog! i have allot of new turbo setups for your 2.2L Cobalt!!!!!! with tuning solution...hit me up!

 

Bring back this thread i keep reading i want more =)
