It's a smaller turbo, the K24.  Some say it's better
because it spools quicker, but you might loose some
top end.

Valve seats or car seats?

The most common mod is to have 40mm intake valves from
the NG motor put in.  My next head will be 40mm
intake, 35 mm inconel exhaust valves, ported, Ti
retainers, and a 272 cam.  You probably don't need all
this though, I'm gunning for 400 whp on a 10vt.
