Ordered it on December 5th and received it on the 31st. Just got to installing it, it really wasn't too hard and comfortably took me (with someone helping) about 2 hours. I've only revved it to about 4k and it does pull harder but I'll update on how it pulls to the redline. Idle is perfectly smooth and it started perfectly after the install. Didn't even disconnect the battery. Here are some pics!
It will be interesting to hear your thoughts on the conversion. I was pleased with my SWR 1 camshaft. By far the best mod you can do to the Ka for the money.
Will you be going for the manifold, too? I can thoroughly recommend it.
