These rotors are brand new with new bearings and were both clearanced .15 mm on the sides all the way to about 2mm from the outer oil control ring. They are also balanced to 10,000 rpm... They would be great for a high boost bridge ported or peri-ported engine.. I was saving them for my next 13B, but now that I'm going 20B I have no use for them since I only have the pair...



The new rotors were around $300 each and the balancing and clearancing was around $250 per rotor..



I'll sell them for $850 shipped to the USA.. PM me if your interested



If you look closely to the side of the rotors in the pic you can see where they were clearance, they are still 2mm apex seal groves, I would recommend atkins seals for who ever wishes to use them. The .15mm side clearance keeps the rotor from colliding with the side plates under high rpm's where eccentric shaft flex can occur...

so these are turbo rotors, right? I'm not up to snuff on the compression for the different rotors.

they are the zenki FC turbo rotors... I'm running a set of used ones in my fd engine right now boosting 22psi.. you can use them in any of the turbo FC, FD, or Cosmo 13B engines..

very intresting. Ill talk to a buddy of mine thats running a Pheriperal ported turbo engine. and Ill let you know..

zenki?? as in series 4??

correct, thus the 8.5:1 compression

god damn it.. Fund my quest to get my car and ass to 7's day at fugi circuit..



O' and bump...
