I have a 1999 spyder with 125k on the engine (2.4 L). I recently picked up a turbo system for it but am wondering if it is too old or has too many miles for the upgrade. The turbo comes from another mitsubishi... factory turbo with manifold and all.

Also, for the oil supply, which will be aftermarket, is there a reason why I cannot return the oil feed into the vavle cover. I see others hook it up to the oil pan, is there a good reason for that?

And one other thing.... is there a reliable way to make sure the turbo unit is good before I install it?

Thanks in advance for the help and feedback.

 

Do a search on this.

 

You can run your oil return through a heat exchanger on the way to the sump. The reason why it is best to return it to the oil pan is because it needs to keep the oil supply to the pump avoiding potential starvation. There could also be some side effects if you return to the valve cover. Trust me you don't want headachesover this, just do it as others do. This way the oil has shortest path back to the pump.

 

Thanks.

 

Should be able to turbocharge any vehicle if the internals can handle it. 1999 isn't too old to turbo your vehicle.

 

This place seriously has everything you need for a mitsubishi

 

i have a 2003 lancer oz rally edition and i wanted to turbo it, where could i find a mitsubishi turbo for a decent price?

 

Use the search button. There is a lot more to it then slapping in a turbo.

 

i realize that, my g.f's dad is a mechanic thats one of the reasons im with her hahaha, but all i really need is the turbo he said he could handle the pipes and all that stuff

 

There's no real way to be sure the turbo is in good shape without just rebuilding it. Although, trying to move the shaft in-out and up-down is a start. Look at the blades and inner housing for any signs of scraping of the blades. If you have any shaftplay, it needs to be rebuilt or replaced.
If you don't plan on upgrading the internals, injectors, head gasket; using fuel management, or anything of the sort, then stay at or below 10psi with just a turbo bolt-on.
BTW, you'd get more power gains if you just swapped the 4g64 head with a 4g63 turbo head. There are plenty of right ups for that swap on the net.
