Hey guys, I'm wanting to do an engine swap on my 280zx eventually. Basically what I'm trying to decide is which engine to toss in it. I'm trying to keep it nissan because I imagine they would go in the easiest. I do not want a domestic engine in it even though I've heard wonders about the LS1. I've been looking at SR20's, CA18's, RB's, VG's and VQ's. Those are the main ones I have been looking at. Use is going to be regular street driving and the occasional track day. The power range of choice would be around the 500+ mark with potential to go farther. Engine should be able to be turbocharged. An estimated cost of building a decent engine would be handy as well. If anyone has any advice or other suggestions, it would be really helpful. Thanks guys.
