Isn't the 1FZ a petrol engine?
Pre-95 is an issue, I have a 94 and I know it creates problems, OBD 1 and other stuff, the turbo 1fz group on Facebook has a lot of info on their pinned post.
I think it depends on what sort of use. A supercharger is working as soon as the engine is turning, so might be better for low speed stuff or towing.
Yea I'm not looking for a race car just want more power and still have a reliable car and don't really want to spend 10k doing it
