quick and easy swap with a bit of a power upgrade go for the A15.. good fun for a small package can swap it out and be going in a day then upgrade some 45 webbers and a mild cam.. otherwise if your willing to do the extra mods on firewall, cross member for the extra power for the L series setup it still wont be anything crazy otherwise id opt to swap for a CA18 still a bit of pain but your getting alot more power and economy out of it and there are endless parts and companies to help with the swap, only real issue for the CA is the pain of wiring.

But none the less a A15 is a quick easy swap and can have some great fun even make it turbo for low cost. some guys have been able to get a NA A15 - 180hp with alot of cash and then guys like mick motor sport A15 turbo run 10 second runs
