I have had this engine since 2001. It started as my daily driver and developed as the car developed as a race car. I gave it a rebuild when I started racing it in 2007 and a freshen up ready for 2014. Since then it has been used for 2 sprint meetings at morgan park, the lakeside classic race meeting and a sponsors ride day. Competing in sport sedans, I'm looking for more power. I could push more boost into it, but I have gone for the 26/30 option.

Head has been ported, new guides and seals, sure cam cams (see spec sheet below) springs to match. I get Gilbert cylinder head engineering to do all my head work.

The block was washed and crack tested. All bungs & welsh were removed/replaced and flushed properly. Bores were torque plate honed for .5 mm Ross forged race pistions. The rods are new Nissan forged items. The mains and big ends have been much ground to the crank with ACL Race bearings. The fly wheel has been lightend and has been balanced along with all of the rotating assembly. ARP studs for mains, big ends head and fly wheel with NPC 5 puck ceramic clutch. The oil pump in an N1 item.

This engine comes less manifolds, computer and loom but complete from balancer to clutch,cam cover to sump pan.

The rev limit has always been set at 7500 and the boost at 14 psi. With a 6 boost manifold and a garret 30 71r it makes 320 rwhp on 12 psi and 360 rwhp on 14 psi.

It is still in the car at the moment. I'll be removing it for the new motor by the end of the month.

Located in Warwick QLD

Asking $ 2000
