There's a local autocross 510 that Dean has had for years, his first motor was a built RX7 rotary with Holley 4 barrel, then he installed a Nissan ZX V6 turbo motor.  The car runs hard, the suspension is well sorted, and he's an above average driver.  With slicks it accelerates hard off the corner.  It's a real sleeper on the street but traction is an issue.  A strong LS would be a handful.
