What to do? Broken 1970 2.0T Piston








Right side of the shortblock:







This is pretty much the condition of all:










But, this is where the kicker is. I have been EXCEEDINGLY careful and gentle throughout this entire disassembly process with the magnesium parts. I am unsnapping the circlips that hold the wristpins to the pistons and this "piece" falls out onto the garage floor. In the back of my mind, I think, "Oh *****!" but tell myself not to worry. I examine the piece, and instantly realize it's a broken piece of the #2 cylinder!




So, I'm now in panic mode.

Guys & gals, what are my options?
  • Where I could find another, single, stock 2.0T piston? 80 mm bore, 66 mm stroke?
  • Is JE Pistons a reasonable option (that is in my price range <$1K) ?
  • Stock 8.6:1, but what piston set could will yield a slightly higher compression?
  • I understand that 2.2L pistons share the same crank, and the 2.0 heads need to be matched. How do they do this?
I do NOT want to switch to 2.2L heads though. I am aiming for near stock, and a stock cam.




Thanks Pelicans in advance for your help,
Pete

I have a NOS and used 2.0T pistons.

I can also supply a set of used, in-spec, OEM 2.0E or 2.0 normal pistons if you'd like to raise compression.


PM me with your email for pics and prices.

I think I have a used set of 2.2L pistons. They came out of a motor that lost a valve spring. I'll sell you all 6 for $50 + shipping. (I have to make sure they are 2.2L pistons first- and they are still in the garage.)

If you are interested we have a very nice set of 67 2.0"S" pistons and cylinders.
This set has been measured, honed and the top ring was replace with new Geotze.

We also have a plethora of good used early pistons and cylinders.

Here is the spec sheet on the cylinders. The pistons show no measurable wear.
