Thread: Our latest and next machining project

isnt there another company that already makes billet SR blocks?

Yes, overseas and rediculously expensive. I believe a company in Australia makes them.

Again, pics of the destruction or it didnt happen. hahaha

Two of the worlds fastest SR20 powered cars had recently cracked the blocks horizontally. Even though it wasnt stress tested to see where the weakness was, it was pretty obvious that pushing the extra power did it. They will still run a sleeve in it just a different custom style sleeve.

Yeah i can tell from the design its designed for a drop in sleeve. Very nice.

Cracked across the deck or at the main bearing side? What was the estimated power the motor was making when this happened?

Will this block be able to receive the 100mm crank from a qr... People would love that big bore with a massive stroke.
