i was talkin with a friend and he was saying how he would love to have a 300zx, and then we both kinda looked at each other and we both knew what the other was thinking. and this maybe a stupid question, but will a 300zx/vg30 fit in a 240? if so which would be a better buy, rb20,sr20, or vg30?

It will fit, DON'T START ANOTHER ENGINE THREAD!!! Do a search in this forum and you will have hundreds of threads on the subject, we don't need another!
