To start off, I would like to rebuild my KA24DE from my '95 SE. The engine has just a tick over 120k on it and I am planning on adding the GReddy turbo kit at a later date. So my goals are pretty simple: Keep the stock compression ratio, possibly do some headwork for flow, clean out and ready the engine for a future turbo (which I will be running at stock boost, no crazy numbers). In short, I want the engine to be as close to new without actually replacing it (unless someone knows how much a replacement 0 mileage engine is). So the question I have is, what do I need/should I get to rebuild it, as my brother (who is well versed in chevy big blocks, but wants to try his hand at this) is going to help me pull and rebuild it, sourcing out any necessary stuff to local shops. I am ignorant as far as this goes, and my brother won't help me unless I come up with the answers. Any suggestions and advice would be helpful, any negative comments about my plans will not be.

you need to find a good local machine shop that will work on your 4cyl. In order to do what you want to do, you will be bringing them your head, block, crankshaft and other various parts. You will need to bore your engine, get new pistons, get a full gasket and timing chain sets. If you crankshaft needs to be ground you will need oversize bearings. You will want to grind the valves and use new valve seals on the head. Thats about it really, if you want to get standard oem type pistons you can get raped at the dealer or pay 100 for a set with rings aftermarket.

you should be able to get oem pistons and rings for about $275 shipped. Source the part numbers and head over too....http://www.nissanparts.cc

where I got mine.

Also I like machine shops that do an computerized oem style hone. Nothing quite like watching a lazy machinist doing a block hone with a cheap hone.

How did you get it for $600 shipped? The website says it's 711.20 for the DE package, which you said yours was a DE. Do you actually have a SOHC KA? Thanks.
