I spent a summer working on a friend's one with an SR20 swap and it really did feel like a cheap jap car. The interior pieces were dreadful and lots of parts would break. You've also gotta bare in mind we're talking about an affordable at the time, 20 year old Jap car, so it's to be expected really. If you're just going to straight up gut it, cage it and racing seat it then you'll be good to go and end up with an affordable setup.
