TSP L15CA Built Shortblock - Available for Pre-Order!

[Savannah@TSP]

Hey guys!

Our L15CA Built Shortblock is available for pre-order! We ran our first built L15CA in our TSP FE1 for testing and it's been performing great.
It is now available to the public. We do have a block that will be ready in about 4-6 weeks, should anyone be interested.

Exciting update! I took a close look at the short block link on the TSP website and have some questions. It looks like the deck surface has been machined quite a bit—the coolant passages between the cylinders are almost flattened. Why did TSP choose to do this?


Additionally, with the deck machined, the 10.5:1 compression ratio pistons might end up around 10.6:1. Why did TSP opt for a higher compression ratio?
