cel after doing turbo upgrade

i did the greddy turbo kit and fmic on the 91 4wd wagon.
here is the problem i am getting.
when i floor it past 4k rpm the engine light comes on then right after that then the oil and battery light comes on. the car will still run but like in limp mode. when i let the car go down to idle it then just dies. i am still able to restart the car and the engine , plus the other lights go away. once agian if i go past 4k rpm it will do the same thing. if i keep it under 4k rpm nothing happens and the car runs fine.
whats going on?
its a greddy turbo kit. no engine managment yet. i am going to be installing it once i get a tune date with a guy i know. but the problem is that it wont be for a month so i need to be able to drive this for about a month for now. so whats going on? what can i do to fix this issue for now. i am installing a boost controller and gauge this next comming week.
any advice or help with this?
UPDATE:
well after a while i have it running.
it runs really well. no other issue other then the age of the car but for the ecu problems, that has been resolved. i hooked up the emanage from greddy and the cel is no longer there. its a hoot to drive but i prefer to get more juice out of it. it will need to be tuned but ill probably use bigger injectors before i do.

the codes dont stay on so i dont know. it turns off right after i turn off the car. from honda tech forum they are saying i am in limp mode cause of
"A MAP sensor check valve", "If you dont you will get a code for running boost with a stock map sensor and your car will go into safe mode".
this sound about right. but again i dont know for sure if this is correct. he didnt really offer a fix or what this part looks like and where it is located or even weather if it will be fixed with my greddy emanage.
i know i need to get some sort of enginemanagement but i am not really getting on the throttle right now so i hope it will be ok. also i dont have a place to tune an emanage from greddy and i dont know if the emanage will work to resolve the problem. i really hope it does i dont want to work anything else for now cause its paid for and have the harness that works for it right now that i paid alot of $$$ for. so either way it needs to work but would like a confirmation that it is enough to make the car run fine.
after the light comes on, let it go down to idle and die, but dont switch off ignition. check what error code the computer is throwing at you. get that code and maybe some people can help you a bit better.
hope you can get this problem fixed soon! good luck
Fundamentally...a real bad idea. Its not like stretching an oil change, or running too little tire pressure. This is like no oil or running your tires on empty.
And if you don't know how to check a code, or even what a MAP sensor is (and at least how to figure out where it is and what it does) you really have no business trying to cobble a turbo together.
As for wanting the car to run (safely) for a month before you "tune it"...well, good luck with that.
Sorry if this sounds harsh.
the sky is blue
we have 12 months in a year
gas makes the car run
the ocean is really big
we breath air
any new info to you in what i just typed?
not trying to be harsh but please keep this to something i can use to help the situation.
please help me and not scold me. the scolding and saying its bad is not tech info to me. i read so many, " you cant do that" and you shouldnt that". so few, "well i have tried this and it worked".
davens, i have read some of your post and you have helped a few others out with some pretty good advice and tech info but saying this doesnt really help for me out because of my situation.
I have to ask. Is it installed in the car?
Im not trying to be a dick at all but I personally wouldn't have turbod it until my tuning date was coming up. Just because that way it gives me less time to fuck something up. If its not your daily driver then thats fine and you can get away with not running it but if it is your daily then everytime you start your car you run a greater and greater chance of breaking something.
Okay...you say you already know this. Great. But that's not what comes across in any of this thread. As far as constructive advice...I see you trying to do something pretty stupid and I was just trying to tell you its not worth the risk. Obviously not what you wanted to hear. I'll keep my mouth shut than. Good luck.
no the emanage is not hooked up yet.
good news tho. i found a tuner that know how to tune emanage. he has done it on subaru's and he said that he will be able to tune this comming weekend. which is very good news for me. this is a daily driver for me. it told him what happends and he said if i have to drive try to stay off the boost as much as possible as i have been, by staying out of 4k or even flooring it. he says that the emanage should help take the cel away. he is doing more reading to make sure this whole week. so far i feel lucky i have not screwed up too much but i have to drive it around town for now. it took about 3 full days to get the turbo on and i was trying to get in on the tune he was going to do. i just thought it was this last weeekend and that i had missed it but luck has it that he is doing this weekend instead.
then would i have to change something mechanically or do i have to just hook up the emanage and tune it, would that just solve it?
