wtf? did i blow my motor?

i have a 87 gxl converted turbo ll.. about 3000 on mazda reman.. all i did a couple days earlier was run no intake. i used a coupler and attached it to the turbo. i was on the freeway and all the sudden the car loss power and it started smoking, i let it off the gas and it shut off. i new gas wasnt going getting into the engine after i checked up on it. after doing the fuel pump jumper thing.. gas finally flowed. it started after push statting it on top of second gear.. it wouldnt idle on its own and poured smoke like crazy.. i can hold the gas at 3000 and it would stay there. did i just mess up my afm or did i blow a rotor?

if you dont have an AFM, then it would cause it to stall out all the time. i dont know how it wouldve started without that in the first place.

run no intake?
might have sucked something up into your turbo making it smoke really bad/restrict airflow.
if the afm isn't plugged in, it would start and immediately die.

What color and smell is the smoke? In the first post you said just coupler on turbo, so did you actually run a N/A AFM on the turbo? Is there any noises...be very detailed as to what exactly is happening. Tell us every symptom, thanks.

when i poped the hood there was oil by the oil filter.. the oil filter is on tight.. so i dont know how it leaked... it was just white smoke it didnt really smell like anything. i could rev the motor it just wouldnt idle or have any low rpm power. under 2000 rpm it would shut off.
the na afm was attached to a coupler which was attached to the turbo. the car is pretty far from me but ill do a compression test later.. it didnt make any strang noises either. thanks

Try putting your intake setup back together and see if it gets better. It really sounds like a AFM problem.

i did put it back together... but is it possible that the afm would screw up like that? it would couse it to smoke?

Ok you said that you ran no intake and still had a filter, what in the hell are you talking about? what exactly did you remove?

Either way, if your smoking like a bitch then intake or no intake, something else is wrong. Sounds like a fucked up coolant seal to me. Since you did have your filter on, apparently, then nothing could have gotten lodged into the turbo to create the lack of power.

Using an NA AFM on a turbo engine should still work, but im sure that the springs are of a different tension on either unit, thus resulting in something not working 100% im sure.

Why?
As for the smoke, it sounds like coolant is getting in to the engine, prob a coolant seal problem.

The only thing I can think of that coul cause white smoke to pour out is a major coolant leak, but someone else might have another idea. Check your coolant levels, are they going down?

What in the mother f*ck is going on in here?



This is one of the dumbest things I have ever read.

An NA engine converted to turbo. Retaining the AFM and air filter, but no tube between the afm and engine, so the engine was free to suck in unfiltered air, and the afm was stuck shut the whole time? How the hell did it even run?

Don't ask us if it's blown. Find out yourself.

Do a compression test.
Even pulses and a psi of 70+ means it should still run fine.

Anything else and yes it's blown.

If it has even pulses and stuff then look elsewhere.

Please clarify:

Tell us everything you have connected to the inlet of the turbo. For example"

"I have the air filter which goes on the AFM which goes to the TID which goes to the inlet of the turbo".

There is a lot of confusion here, and we'll get nowhere unless it is cleared up. Posting in complete sentences with correct spelling also helps.
