I meant the engine weight.
Shock interchangeability, I trust that it'd fit, or fit with some minor adaptations as much as a Corolla shock would fit a Matrix, or that a Highlander control arm would fit an RX330, things that share a platform usually have compatible or nearly chassis components.
I was on a the website of a renowned suspension provider earlier today, and I couldn't find similar part numbers between the 240 and 180, but that might be because one was on the japanese site while the other was on the american site, or that these part number differences account for the different spring and damper rates, etc.
1000 bucks is still some nice coin, so if all else fails, I'd still email or call someone at the place that makes the kit you're interested in and ask, or ask people in the nissan tuning scene, they're bound to know more of what fits and what doesn't between local and export models and across nameplates.
