ok i used to have a 1991 240sx, sr20det swap, and those cars are made for it, i had it gutted, driver and passenger seat only, i had taylor from secret services (who drives a RHD 240sx with an rb25det in it) give me a little bit of pointers on it and now that i am getting the feel for it, it is actually very fun and somethin that i enjoy doing with my mustang also it takes alot of skill, one wrong move and u can end up in a tree.. so its jus to each is own, if u can do it good u love it, if uve tried and cant do it u hate it..
