'89 200T block question

[Bruce Bell]

I'm with Hew. All are forged. In the 80's there were cast 5 cyl. stroker
cranks available through aftermarket suppliers; however, they were
reported to warp when machined. Also, all NG, NF and 7A motors had oil
squirters. This list has often rumored that there were forged vs cast
piston differences too. I suspect the JT uses the same pistons as the
MC2, albeit with different rings.

Snip.....
On one note, The non-turbo uses cast pistons and crank, so I wouldn't
turbocharge this. I also believe it doesn't have the oil squirters.
