Excuse me? The b series is not a junk obsolete motor im not going to get in a debate over that. The sohc honda motor is a better comparison to the spree engine NOT the b series. It thier most popular engine and most swapped engine out of any other honda engine. A k series is actually NOT worth te money. A H22 mated to the itr transmission is the best bang for your buck and will smoke most k series swaps. You wanna get into a debate over this then come on to jdmuniverse.com same screen name. Theres tons of builders ready to back everything i just said

When taking off the flywheel I noticed it came off pretty easy and I didn't even have to use a puller. Then the stator wasn't that tight either, it's starting to make sense why the plastic fan looks like it was rubbing.

Looking good so far.

What are your goals with this rebuild?

Thanks, After I tear it down I'm going to sandblast.

My plan is to do some porting but nothing extreme. I'll open the intake window in the case a bit, port the intake manifold too. Smooth out the casting flaws and polish the inside of the case. Open up the intake/exhaust ports on the cylinder. Then hopefully I'll have a good running spree that breathes better and has better acceleration. I'll eventually try the pulley mod since I have a spare one.

If I'm successful then I move onto my larger engine and do the same. So this will be a good engine to practice on.

Porting can be very relaxing, I love doing it. Take your time and try not to do all at once. Any porting on a spree helps. I did some to my spree, diddnt raise the exhaust port yet, it was a very noticable differance despite that.

Thanks, I'm no photographer. I have a simple point'click sony camera I use to take a bunch of pictures, then choose the best quality ones. I'm uploading more tear down pics right now...

Yeah, I know what you mean. I've done a lot of car related polishing projects, using power tools for long periods of time. I usually wear headphones and listen to my favorite music or talk show on my mp3 player. But I don't want to get too relaxed and grind through the case.

Yeah I do the same thing, I have ear protectors that have an FM radio built in. I put on the classic rock and get to it. My new fav tools for porting are the diamond bits that fit a dremel. I paid about 10 or 12$ for a large selection.

Those are the small set I just got a bigger set with way more bits. I start out with carbide burr cutters of varying shapes and then really get stuff dialed in with the diamond bits.
