For 20 grand I would get a L28 Skyline.... and later replace the L28 with a RB25det.
Just went throught the Junk Mail, lots of 2.8 Skylines there... http://www.junkmail.co.za
If you can get a 2.0 SGLi model for a bargain, it uses the same drivetrain as the 3.0 SGLi, just add turbo, nos or RD25/6det/tt
