I bought a motor on this forum and the guy told me it was an 87 T1. That is the same motor that I have but the flywheel is a 8 bolt on the old motor. The new motor has a 6 bolt. The block is stamped 85 on the new one. So I got a 6 bolt flywheel and it doesn't match up. What's the deal? This may be a stupid question but I'll ask anyway. Is there a difference on turbo and non turbo flywheels, and if this isn't a turbo motor can I make it one? Thanks

Yes there is a difference. The turbo flywheel will be 15mm larger diameter. (215 vs 230mm)
You can swap in a turbo FW for a TBI one.

On making it a turbo engine ... if it's now really TBI you'll be looking at a piston change and possibly connecting rods. '85 connecting rods are pretty strong .... if it's a '86 TBI build you'll be looking to swap in the better rods. (Need to check part numbers here for what you have). Need to have the block drilled for turbo oil return.

Optionally, having the block tapped for the larger head bolts <---- if you're going to run some big boost you'd do this.

.... or, sell what you've got and buy a later model turbo short block.

So now what the **** do I do?
Puppet told you there was an offset to the holes. Did you take this into account yet? Put the engine to TDC on the compression stroke and hold the flywheel with the timing mark UP (12 o'clock). see if it doesn't line up now.

good luck.
