I NEED HELP!!! i have a 1988 turbo II and it just started smoking today, badly. i parked it last night and it was fine. the motor was rebuilt 40k ago with 3mm apex seals. if anyone out there knows about this, please pm me and call me, hell.... come over and help me!!! oh, and the smoke is coming from the exhaust and the turbo side. i'm hoping it's just a turbo. thanks guys.

 

Hey hey. Im back, My previous internet provider craped out on me. But I now have a new one.

carolinaTurboII: Yeah its probably your turbo, upgrade that baby.

 

it's a new turbo on there . pm me

 

what color smoke? and it smokes from the engine bay too?

 

white, and yes from the turbo it looks like.

 

turbo coolant seals? sounds liek the same problem a 10AE had i looked at over thanksgiving. ran fine, just threw white smoke out from under the turbo and out the exhaust. any coolant loss?

 

if its white then there is a good chance that its ur coolant seals. but like jamin^^ said above, is it loosing coolant? also have you recently over heated the engine?

 

i have had a small coolant leak, but it has not overheated at all. and now when i try and crank it, it back fires.

 

how much boost were you running? i see in your sig that you have a BNR stage 2 and streetport, but only an FCD. is that correct? if so, i would almost bet money that your motor is blown due to running lean. although you have 720 secondaries, the stock ECU still thinks you have stock injectors. so it will inject a little more fuel, but not enough or in the right places. also, the FCD tricks the ecu into thinking it is running stock boost levels, so it obviously wont cut fuel to the engine. so if it is injecting stock boost level fuel for, say, 10 PSI, then it is running WAY lean. the stage 2 has a 60-1 compressor wheel right? it is moving way to much air for a stock ECU. you really need to invest in atleast an SAFC(cheater way out), an Rtek, or a full standalone.

Check your coolant hoses to your turbo "supply and return" (there should be two coolant hoses hard to see but that may be the source of your trouble - they could be cracked and dumping just enough coolant on the exhaust). If so, that should be a cheap fix. If not, and if still coming out of the turbo side then check you seals and lastly, do a compression test on your engine.

Overall, how is the car running?

 

the car runs.. a little rough but it's cold.

 

alright i guess ur gonna ignore what i said above?

 

dgregg100 made a good point when talking about fuel to air ratios. It would be a good idea for you to upgrad your stock ECU. I am not sure what options you have on the FC but I have seen several including the ones dgregg mentioned.

 

if anything i ran rich as hell. well, thats what the black rear bumper and my a/f gauge says. it's also controlled by safcII aswell... i'm not ignoring you, i posted b4 i saw what you wrote.

 

is that a wideband a/f gauge?

when i first bought my TII, it only had an safc II and rtek 1.7 (720cc sec), and even that pinged on me a few times. I ended up ripping out the safc and upgrading to rtek 2.0, runs a hell of a lot safer now

but anyway i dont think it sounds like your motor is popped due to that, sounds like a coolant seal combined with an exhaust leak around your turbo. I think you can test that by letting it idle while leaving off the radiator cap.. if you see bubbles rising, then exhaust is getting into your coolant = rebuild

but there are a lot of good guys around here that do rebuilds, Ernst at rx7world, Rotaryressurection in TN, maybe Chris may want to do it too

 

oh, ok i didnt know that you had an SAFC as well. yep most likely your coolant seals now. ill rebuild your engine for you if you want. shot me a PM if ur interested.

i can't imagine that rebuilds are inexpensive though... i may be broke
