I find it hard to believe you didn't know you aren't suppost to do that.

Ive done it a 1000 times on my bike, truck, mustang, and my camaro. Never had one problem. Its not that I didnt know, just never had any problems with it until I get this car.

I have a suggestion, next time you try to use smartassness re-read the thread. I didnt wash the hood. I washed under the hood meaning the engine, engine bay!

IT FINALLY RUNS! Replaced the igniter with one off my parts car and bam, runs like a champ. Still got the MAF code and its a little low on power but its running is the main thing. About to do a compression check on all cylinders and seewhere that stands. Also have some rod knock. Thought maybe it was something loose but its defiantly rod knock. Im going to track down a MAF and see if I can rid of that code and then Ill start form there. Going to pull the motor from the donor car this weekend and start getting it ready to be swapped when this one dies. I did shim the waste gate .022 so the boost was right at 7psi. I dont guess ill up the boost until I get the new motor ready. But thankfully she's running.

Z'mnypit · 05-03-2007, 01:07 AM

Just finished the compression check and heres what I got:

1- 130psi
2- 130psi
3- 130psi
4- 130psi
5- 136psi
6- 134psi

Sound about right? Car was still hot from just getting back from driving it. 142psi should be perfect so 4 of them are getting close!

I also put my NGK's back in there and now it has a miss under load. So looks like tommorow ill be swapping the NGK's back out. Always something!

IHateHacks · 05-03-2007, 01:20 AM

Those numbers are a little low, minimum cylinder pressure is 128psi on turbo models so you are pushing it to the limit.

Unfortunatly, I was right about the rod knock. Definately from running the engine with all the coolant in it. Not saying you did it. I'm sure the retard that you bought it from drove it like that for awhile.

Glad you got it running. I knew it was either the coil packs, MAF or igniter that got soaked and took a dump.

Keep us posted!

Yep! Thats why the rebuild is starting real soon.

That and it sat filled with antifreeze and oil mixed for a long time.

Still got replace the maf. Its still got that code. Im just glad the issue is resolved, I was about to go nuts.

Well needless to say that was a bad idea. Everysince then its ran like pure crap. Spits, sputter,no power, backfiring idles fine, want rev past 2500rpm even when it does rev that high its all it will do to get there. I have one SES code being 31 for the MAF. Im pretty sure that isnt the problem though beings the code was there the couple days it ran good.

Ive swapped out all plugs with new ones, changed air filter, cleaned all electrical plugs with start fluid and still runs like crap. Timing is right at 10-12* everything is lined up right. Then again it ran fine for two days with nothing being changed other then washing under the hood.

Yesterday, I found a vacuum leak right at the TB where it bolts up to the intake. Replaced that and the fuel filter today and still runs like crap. Im all out of ideas and cant think of anything else to try since Im new to these cars.

The car is an 87, 5spd, turbo.

Any suggestions?

im sorry i often confuse smartassness with dumbassness... my confusion cause you said under the hood and i thought you meant underside.

supramacist · 05-04-2007, 01:22 AM

You shouldn't hose a supra engine down, the main reason being that there are 2 different types of metal parented together at the head gasket.

I think this is why they were giving you a hard time. But I could be wrong.

Z'mnypit · 05-14-2007, 01:54 PM

Alright guys I know its been awhile since Ive been back here. Ive been fighting with this stupid car for the past week with no luck. Heres my issue now: Got rid of all the SES lights except for the 52 (knock sensor) I dont know whats up with this code, Ive rewired the sensors and it still does it. Guess next Ill swap them out. The MAF is new, and all the other codes are gone. Now, it will start up fine, run fine but when the boost kicks in it will fall on its face. You literly have to let out of the gas watch the boost gauge drop then get back in the throttle to get it to move. As long as you dont go WOT or under a load its fine. But once you hit boost it nose dives. Ive checked every clamp, every pipe and I cant find any leaks. Ive checked the BPV and you cant blow through it at all. Ive backed the timing way off and all it did then was black smoke. So I know its getting the gas then. Im all out of options. I have a uncle who is a head mechanic at a local toyota dealership and was going to take him the car friday but hes in the hospital now so that puts a damper on that. Im open to any suggestions to try, Im on my last nerve with this car.

Thanks!
