This has been discussed thoroughly here. Search previous posts for the KF-ZE topic. One of our wonderful moderators, Barry Clark (custommx3, his site is
http://www.custommx3.com or
http://www.barrykclark.com -- he may have his kf swap documented on there) has a 92 GS that I bought in Birmingham, brought to memphis, and after being through 3 or 4 owners, found its way to his drive... He has a KF in it, but it failed within 10 minutes of startup due to faulty/worn rings, it appears... You can find the KL-ZE for just a few dollars more, and as far as I recall, the electronics needed (VAF, ECU, etc) are more compatible with your K8 than are the KF-ZE's... Plus, you're talking another 30 horsepower from the KL-ZE motor, and a good bit more torque... WELL worth the extra $$, as well as less headache finding replacement parts, since there's a bigger market for the KL-ZE, and since it has an American market brother (KL-DE, found in MX-6, 626, Probe GT, Millennia). Do a search, and you're SURE to find everything you need to know about this, and if all else fails, email Barry and he'll tell you evertything you never cared to know.
