Two PSI New cylinders; yes, they are "pretty cool", and as Matuus alluded to; a hard sell since the kits are incomplete.

These are really collector items, hopefully someone pics them up and puts them to good use.

Those are nice cylinders, old school PSI…. for some these are a collector’s dream.

One issue is no heads, domes or piston kits to make just like PSI had or intended years ago. If they were at BDT, I would make a custom spacer plate, de-stroke or stroke the crankshaft (can go either way depending on the PSI cylinder cast setup, they made a couple of different versions), find the correct rod (size, length of rod).

Then by matching the proper rod & stroke, custom spacer plate, proper porting & dome/head design (would need to make these from Billet) and using a currently available Piston kit, you can bore and send to Nikasil Plating, then Diamond hone to size.

You can set the PSI’s up to be a real nice running engine; at BDT we have built 3 of these over the past 4-5 years.
