Default I will be buying a 1988 N/A supra in 2 days, 1 question

1988 Toyota Supra

this car is amazingly clean, and 100 percent stock, saturday I will be testing the compression of the cylinders, if those are fine then I will be driving it home.

BTW: where can the fuse for the fuel pump be found? that way when cranking there will be no gas going to engine.
If the compression is fine should I retorque the head to the proper amount (to prevent it from going bad), or let it be?

I have read that if it is that old and has sat like that fine for 20 years that adjusting it might encourage it to go bad.

What do people think... is this an opinion thing, or was someone misinformed?
Thanks so much for help!

EDIT: Also what fluids/hoses/belts should I be replacing as a priority?

you can pull the EFI relay which is located in the fuse box under the hood, on the drivers side. That will disable fuel for you. Things you will want to do right off the bat
Oil change-for sure
coolant- for sure
power steering- would be a good idea
tranny fluid- would be a good idea. Use Redline MT-90
Diff fluid- would be a good idea.
Brake fluid- a must if its looking old or dark
check brakes for wear
Check all suspension components and replace as necessary

You might want to ask when and where the head gasket has been changed if they are the orig owners. With 185k miles i am assuming it has blown the head gasket sometime in its life, and if it hasn't, i would be prepared for it to come along soon.

Also: Lift up the wood panel in the trunk and look in the spare tire well, where it sits. This is a spot known to accumulate water from leaky hatch seals and get rusted out.

so should I retorque the head to prevent the headgasket from blowing, or should I let it be as it has lasted so long already?

Thanks for the reply

I honestly don't know so i don't want to give you incorrect info, but from what i have read it seems to be pretty well debated and people have different opinions. I don't think i would do it personally, but that is just me.

if the headgasket wasnt replaced i would just change all the fluids and drive the car really easy dont rev it high or anything untill you have some $ saved up to replace it. It's a pretty costly job i spent $1,200 and thats with a employee discount working at a toyota delership but i also replaced all the belts gaskets water pump ect.

Also check the plastic shroud under the fuel tank. Moisture and leaves like to accumulate in between there and may start to rust the tank. Check all the vacuum hoses and coolant hoses (ISC valve) on the intake manifold, most of mine were shot when I got my car.

I looked at Cygnus X1 Home Page

to figure out what you need to do in order to get to the spark plugs, however this is for a turbo... can someone list steps for an N/A?


Thanks to everyone for help

you need to remove quite a bit of stuff. The throttle body, brackets, throttle linkage, y pipe and brackets. Then they are in plain sight. Dont expect to be in and out of there super quick especially if its your first time taking it apart. Good luck!

I like the interior on that car. Espicially the leather seats and the color of them.
