We have a number of 240 and 260 over here running L28 engines, fairly heavily worked, but producing some good power, and giving many a more powerful car a run for their money. Even with a cage 240's weigh nothing, if you're thinking about tracking. Or another cool option is putting a VQ35DE engine in, same again we've got them running over here, go very well and still both options are proper Zed engines.
