Really, i don't need these kind of comments, they don't help me. As i mentioned in my original quote "im not sure" and if i'm wrong feel free to inform me as i don't know much about the 7m block yet as im a brand new owner. I know the pistons are not directly cooled as they obviously can't be but what i do know is that they and the chamber emit the primary source of heat which the coolant attempts to extract from various other locations. Based on that if the radiant temps are not even approaching 190*F marks then i would think its safe to assume the temps in the block are not approaching a dangerous, and extremely high temperature, whatever it would be, to melt the pistons.
As far as teh couplers are concerned i can't tell yet, as i'm not around my car yet b/c its my sisters, in a sense, belated wedding reception today and i am away. I'll know later tonight, and thanks to who posted that thread for the 'at home leak test kit', its a great idea. I'll also be reseting/messing with the boost control as i think it could be the main reason this is happening.

:bigthumb: Thanks for the offer but unfortunately the car is not drivealbe, i tried the other day and after 15 minutes of driving the gas pedal was seemingly non-repsonsive as i continually lost power for whatever reason, no matter the gear or RPM. I have a dyno tuning scheduled for the 5th so we'll see what happens after that. Ill keep it in mind though if things don't work out or if i have other problems i'm not sure about later on :thumbup:
It is not your boost control. The engine would run fine with the wastegate fully open, you just won't get any boost. Find/fix the leak.
You melt pistons by running lean or by detonation.

It has nothing to do with you not knowing about the 7M and everything to do with you not knowing how engines work. I could easily tell you what your car's problem probably is but like many here I don't typically respond to posts where it's obvious the poster is clueless without excuse. If you really want help get off your ass and help yourself by learning the basics and stop asking to be spoon fed.
:cry: well pardon my ignorance as far as boosted engines are concerned, but we're well past basics here as the majority of the population can't even tell the difference between engine oil and trans oil. People come to these sites for information and help, you're welcome to join in. If in fact you DO know the answer then stop being an asshole and feel free to spill, and if you don't bother with questions "not worthy" of your time then why even bother comment on posts like mine, its obviously a waste of your precious time.

understandable, it has direct contact

IwantMKIII- you've got to tread lightly in territories that are unknown to you. this really has nothing to do with boosted engines, but basic mechanical knowledge of how things on ANY motor works.
that being said- the code 52 will cause your car to run badly, overly rich, and it will retard the timing as well. this is caused because the TCCS (the engine computer/ecu) isn't getting input from one or both of the knock sensors. the way to fix that can be found here: http://www.supras.com/06/techcenter/display.php?QID=69
i would first pull the EFI fuse for 30+ seconds to clear the ECU of any stored codes, as you have no clue how old they are. once they're clear, start the car and let it run. check the codes again, and see what you've got.
get that fuel pressure gauge hooked up so we can at least make sure it's properly set.

Thanks :bigthumb: for the help, ill check it out, and get on the FP ASAP. As far as the code 52, i read in the manual that was something related to starter signal??
well i got back to stock FP, and it idles better and my AF ratio isn't leaning so much now its more rich than anything. I find that in first and second it will let me go beyond 4K and boost little with quite a bit of vibration, in third and up the feul will just cut out and it will send you flying forward, in 5th it will do this when my boost control says -15 or so.....any ideas????
ok, my brother rode in the car with me and he had owned a supra previously and said the air he heard was WAY WAY too loud, so im going with boost leak like some of you said, now my next question is if there is one, when the boost begins...will the fuel cut right away??
