Need help putting engine back together

shawn87gta · 11-24-2005, 04:21 PM

Not that this helps you now, but it might be helpful to others reading the post or yourself in the future. When I took my GM TPI motor apart I labeled every wire & hose and the corresponding connections, and made notes along the way. This takes a bit longer but you'll more than make up the time at reassembly. I also took digital pics before starting to note locations of wires, brackets, accessories, belt routing, etc. My GTA is pre-serpentine and has four separate belts, and I can attest that the brackets & accessories will mount up incorrectly... I'll take pics at any point where I look at it and think "this'll be a pain to get back together right", and after other parts are out of the way to get a clearer pic.

I've replaced the exhaust gasket on my wifes '87NA and my '90 turbo. The worst problem is stripping the threads in the head as the nuts rust on and the stud comes out of the the head + thread. Both cars have one stud stripped but the gaskets are holding. Getting the Turbo on and off is a real pain with the connections underneath but I did it in a morning after lots of trys with different spanners.I did the head gasket on my sons '88NA, I labled all the hoses with different coloured tape, you also need to mark their route thro' the other pipework. Most of the electrical connectors are different so only go back in one place - they are difficult to get apart use very small screw drivers down their sides to release the clips. Thought of using a standard Toyota gasket but after all the work and the mess the old one was in decided to use metal one - it leaked initially - steam out of the exhaust I used some rad seal and it settled down in week and hasn't used any water in the last 6 months. I had the head skimmed but just cleaned the block (not very well). I didn't retorque the head as I had already put it up to the revised high setting.

this held me up for a weekend when i put my cars head back on. next weekend i had to take turbo off and replace a leaking oil gasket where that metal oil pipe fits to the turbo, took less than an afternoon.

1/4" 12mm tube socket with 3 extensions and you can just line it up onto the nuts on the bottom of the turbo with your ratchet below the suspension arm. keep all the nuts loose just on the first couple of threads untill you have them all started. its very possible, just a mean job ... if that's the bit youre having trouble with ?

the vaccum lines are actually kinda easy once you get into what i call my " toyota supra rythm. "
small lines are boost, bigger ones are manifold coolant, bigger again do boost, everything else is boost.

ps has somebody sent you a pic of a supra engine froma certain angle yet ? if you can get some specific questions im sure somebody will send you an answer.

Let me know if you want photos taken of particular areas--I have a 1990 Turbo (and an '88).

Yes please, can you get close ups of the engine all around?

Thank you so much...

next time, get those numbered sticker/tags that are sold at most autoparts stores. The stickerbooks have pairs of numbers for you to put a number on the hose and the matching number on its connect point. (it saves a lot of hair pulling)

I'm in the same boat with an 87 turbo. Only I did not remove the engine, a mechanic did it, and to make a long story short the project to much longer than anticipated and I moved out of state. Now the car is ready to go back together but the mechanic didnt label anything. I would also very much appreciate any close up photos of the engine bay and/or hints about reassemblying the 7MGTE.

I have owned this car for nearly 3 yrs and have only driven it about 3 or 4 times, ( I bought it with a rod knock with the intent to build a 12 sec car) the wait is killing me..... any help would get buckets of gratitude (I would say cash, but the black hole with a turbo badge has swallowed most of that!)

Bit of a street racer, I guess. I'm told they're fast. Delivering it home with a friend driving the Supra for the first time. I drop gears and make a scream from the twin pipes flowing down this pony's flanks and it takes off like it's tail's on fire. I look back when the Honda gets to its tap-out and the Supra's only two lengths behind. No one I've let ride my bike has told me its slow, they've all loved the thing. That car is a good thing indeed.
