Need Help Diagnosing a HUGE Problem!!!

[fst_trbo240sx]

Ok so i have a s13 with a blacktop sr20det installed. I was on the interstate the other night and ran a couple of mustang gt's. Well i dropped it down a gear and beat them and as soon as i did i let off to get back down to speed and everything seemed normal. well then i tried to give it some gas and it did nothing at all just jerked alot. i finally slowed down to a dead stop on the side of the interstate and the car died. tried to crank it up and nothing. tried again and it cranked up but ran VERY VERY rough. it was sputtering and jerking and sounded aweful. so i gave it some gas and let off the clutch and the fastest it would go was 10-12 MPH. I dont really know how to tell if i have a cracked block or blown head gasket or threw a rod or what. can someone please help me or give me some advice? it starts up now but when it idles it just sounds so sick and idles so rough and when i give it some gas it just choked basically. it kinda sounds like its missing on 2 or 3 cylinders. thanks in advance guys!

umm..Im gonna say 9 out of 10 chance that you just popped off a IC Piping off the hose,lol...SInce the boost inst cycling threw the engine its running rich and dumping fuel into the engine whitch is cause it to run like shit..examine your IC piping..sorry sounds simple butits happened to me.

ya man have u checked your intercooler piping? sounds like thats most likely the problem with your information given.

Lots of black smoke? I would check for a boost leak but also pull your valve cover off, Im sure you might see some of your rocker arms laying in there! Thats what happen to me it sounded like a subrau. so check those 2 things

peace

Leak if its blowin black smoke...

you say 10-12 MPH, that doesnt say shit. In what gear...can you go faster if you shift up early...is it only when you are on your throttle hard?

Are you running stock boost? Stock Fuel?

sounds like you need to study up on your motor as well....\

cracked Block, Blown Headgasket? DO you know the symptoms of that? Oil in the water? Water in the Oil? Have Water? Have Oil?

10-12 iin forst gear at almost full throttle if i try to shift up the rps will drop and it will die....i have not seen any water in the oil and its white smock no black smoke. im running about 12 psi boost and stcok injectors with a walboro fuel pump

Sounds like a piping leak. It won't really run if one of those grommets blow off. Checked them yet?

EDIT: Wait a minute, WHITE smoke? Huge clouds of it or a little bit? Might want to check your turbo and look under the valve cover if there's no piping leaks. How's oil pressure, water temp, etc?

[kuramaya]

White Smoke is never a good thing. Is your oil milky? Is your coolant milky/oily?

[fst_trbo240sx]

well i went and looked at the car tonight and it was in intercooler pipe and it wasnt a whole lot of white smoke just a little bit

[kuramaya]

Ah leak, a little white smoke could be turbo going out, or just condensation also..

[fst_trbo240sx]

well i reconnected my intercooler pipe and now the car motor wont even turn over...i looked and i had accidentally unplugged a connection....well i plugeed it back up and it still wont turn over.....i have no clue now
