Being partially biased, I still must say that my brothers 510 is probably the best in the world.

Powered by a 180SX Silvia sourced SR20DET, also sporting 4 wheel discs, R200 LSD and original Silvia Gearbox. This 1600 has grunt on tap. It's also finished with perfection. Look out for it in Feb/Mar issue of Fast Fours and Rotaries. (Australian Magazine)

I'll post pictures as I get time to scan them.
