I bought an 87 GL-10 turbo with a blown head gasket recently. I tore the engine down to find both the heads have cracked and the cylinder bores are rusted and have scarred. I've been thinking about getting the cylinders rebored, but I don't know where I could find some oversized pistons. Does anyone know where I could look? Or is there a better alternative I should look at?

Before GD says it.. it's a dead platform. get a early 90's 2.2L Legacy or Impreza :)

If you want to keep that car, best bet is find a used engine, but that will likely be tough.

Other option, ej 2.2. A lot of work, but so is trying to find parts for the original, and a na 2.2 is more reliable than a turbo ea and more power.

Well that was your first mistake (buying it)...... dont make another one. No parts are available. And proper machining (line hone, rebore, etc) would be extremely expensive due to no one having their equipment setup for the process on that engine. Just a line hone would likely cost $1k and then you have cylinder boring.... no one has a bore plate....oil pumps are discontinued... It would cost far more than the car is worth. It's not feasible and what you would end up with would still be an EA82T.... yuck.

If it's got a really nice body consider the EJ22 swap. More power than the 1.8 Turbo and no turbo complexity.

Used, good condition EA82T..... that's laughable. Such a thing pretty much no longer exists as far as I know. Might as well look for the pot-o-gold and try to catch the leprechaun.

That's what I figured, thus suggesting the EJ.

All EA heads crack between the valve seats - that's actually normal and benign. But on a blown headgasket EA82T that often can mean the cracks go down into the exhaust ports.

Can you tell if they're just surface cracks or actually extend down into the head far enough to be problematic?

Otherwise yeah they're ancient and old. 30 years of hoses fittings and seals to leak or fail and that's assuming all the previous owners took good care of a cheap car that's not worth much for 30 years and the last one didn't just run it into the ground due to the failing gaskets.

It's not impossible but choose carefully.

There's a JDM EA82 on craigslist in Atlanta. Not sure if it was turbo or not.

What do you do when reality infringes upon your frolicking woodland creature, unicorn, rainbow, and lighting bug butt view of the world..... stick your head back in the sand of course.

 

I can't be sorry for the truth, and have no time to sugar coat it. There's no excuse for not asking these questions BEFORE buying some automotive albatross to hang around your neck.

Oh my friggin god, I about choked on my coffee.  EAlbatross82!!!

 

Hey at least there is a way to loosen the noose in the form of an EJ22.

 

 

The OP here has the best platform too.

 

 MPFI car to start, Large line, Baffled fuel tank and F.I. pump.  

 

And if it's 5spd, he can stuff it's guts in a EJ trans case and use EJ clutch no adapter plate without any driveline or shifter mods and keep true 4wd and or difflock whichever he's got.  

 

Being an 87 could be either.
