Well guys, my situation is that I have a 2000 tiburon, I just put a custom turbo kit on it and when I start it with the i/c piping hooked up and rev it. It stops at 3k rpms and bog down and dies. If I disconnect a coupler it runs just fine so obviously it doesn't like boost. I currently don't have a exhaust system welded up yet so no primary o2 sensor. I put new ngk plugs in it. I blew the seal on my turbo and have oil out the exhaust and I'm currently rebuilding it. I just now swapped the pcv out and I'm going with a catch can. I'm not tuned yet and that might be a problem. I know I'm gonna get flamed for this but I'm desparate to find out what's wrong with this thing. It ran perfect before. Primary o2? Fuel cut? Please help.

So . . . with an incomplete fuel management system, your engine won't run right? That's wild.

Its only set for 5 psi. I see people running without tunes all the time.

Honestly, it goes straight into limp mode at 3k.

You see people going without tunes all the time? I can just as easily say I see people all the time who TRIED to go without a tune and holed a piston or burned their rings.



We have seen many members and associates off this site have incomplete forced induction setups blow up their engines, and we knew it would happen. Your car is telling you it needs to be completely assembled by going into limp mode. You will get very little help from the people who know perfectly well how to put together a turbo kit and do some rudimentary tuning, until you show some sort of intention to actually complete your kit.

1. Finish the engine management and fueling installation
   
2. Get a basic tune on your not-the-original-computer engine management
   
3. Go to a proper dyno shop for a full tune
   
4. Report back with awesomeness.
