K04 turbo!
 

Hey guys, I just recently picked up a K04 turbo off of a stock cobalt. I got it for next to nothing. Now here's my question! Is is possible for me to use this cobalt SS turbo on my monte? I've contacted zzp and asked them about their crossover exhaust turbo manifold, they told me my turbo wouldn't bolt up. I went on and asked if they could fabricated it and make it work for me and I would be more than glad to pay an extra 100$ or more if need. They said no, I went on to ask if it was possible, and if it could be done! Still no reply. Doesn't Anyone know what I need to do or what I should do. Or tips and advice to help me with this build! Thanks in advanced!

I will honestly say I don't know much about turbos. But one concern I'd have is even if you can make it bolt up to the monte, how good well a turbo designed for a 4 cylinder car work on a monte? Second the money it would cost to custom fab things to make this work, how close would you be to an out of the box turbo kit that is simply volt it up and go?

I'm sure you could find a speed shop in a large city that could custom fab a turbo manifold for you. You'd just need a tune to go along with it.

Anything can be done with enough money, but by the time a custom setup is made, you'll probably be at or over the price of a complete 3800 turbo kit. Might be best to just sell the turbo for some profit.

They probably don't want to deal with fitment issues for the flange and downpipe for a one-off setup. They make their kits to be a bolt on setup and make their money that way vs custom engineering each kit.

There's no reason why you couldn't buy their kit and take it to a local fab shop to modify it to fit your turbo. The question is- why? That turbo is probably pretty small being that it came off an engine about half the size of your current one. I could see doing custom fab work for some kind of special turbo, but for trying to rig up a junkyard turbo setup, I just don't see it being worth it if you can't do the custom fab work yourself.

Have you considered just buying a bolt on used turbo kit?

Where would I even look/ Find a used turbo kit for 3800 cars?!

Clubgp.com or some of the 3800 facebook pages

Exactly as nitehawk said- clubgp, 3800pro, grandprixforums.net- search around on the various wbody sites.

If you don't want to mess with trying to find a used kit somewhere- a new Z3 kit is only about $3k.

Don't use a k04 and as already said look for a used turbo kit for cheap. If I'm not mistaking I told you to find a used turbo kit and told you the sites to look for them a while ago...
