KA24DE rebuild help

[Vannik]

im planning on rebuilding my s13 KA24DE due to problems, i.e; very high mileage, ticking, missfiring, etc. So i plan on putting in as many decent aftermarket parts into it as i can.

the problem is that im relatively new to the car scene so im not sure what brands and where to find some trustworthy sites. ive been screwed over on the net before and im trying not to have that happen again.

Thanks

Are you planning a stock rebuild, or looking down the road a bit for performance enhancements like a naturally aspirated high compression or turbo setup?

im pretty content having it an N/A for awhile. but ill eventually look towards getting a turbo kit for it.

Hopefully somebody experienced will assist with your rebuild since you are new to the car scene as you say. I've been down this road many-many times with people that want to rebuild or build for a boosted engine. If you want to boost 'later', it helps to start the project right. Personally, if you're going to be NA for a long while, simply do a completely stock rebuild using quality Nissan parts. Then, you could get another engine, put it on a stand and tinker with it. Meanwhile, hunt around for 'performance' parts. Do your homework. Like stated here, start with all the sponsored parts shops on this forum as they prove to be a good source of trusted vendors. Look and search for all the modified 240s on this site too. Most will have a detailed list of their 'build', or (hopefully) can assist you with questions pertaining to their setup. You can see my list of parts and pictures on my Cardomain link in my signature http://www.cardomain.com/ride/3828985. Everything is going to cost $$$ ... and the faster you wanna go, the more you're gonna spend. If your end goal is a high performance NA setup, start by having the block tanked, bored and honed. Go with larger higher compression pistons and a good set of cams. You don't really need forged rods unless you plan on nitrous. Porting the head can make a tremendous difference in performance simply due to increased engine breathability. Have the head reworked and fit in some stainless oversized valves too. Use ARP head and main studs. Consider an underdrive pulley as a nice bolt-on. Open up the air intake by replacing with a cold air kit; then do the exhaust with a header and larger diameter pipe to a high flow muffler. You'll then need a remapping of the ECU for a performance tune. Tons of other little incidentals I could ramble on about (bearings, injectors, fuel delivery, head gasket, etc.), but a lot of that comes with the territory of deciding what to plan for. With any rebuild, especially when using aftermarket parts, have the entire rotating assembly balanced (pistons, rods, crank, flywheel). If you plan for a boosted car later, a lot of the same applies for the engine rebuild except I would go with lower compression pistons (then that of factory) and definitely forged rods. But then, this all depends on your goals for boost pressure. A boosted KA is going to be 3-4 times more expensive than investing in the NA derivitive. In either build, you will need to be able to transfer the increased power to the rear wheels via a good clutch assembly (if yours is manual) and you may also want to consider swapping out the rear differential for the VLSD (there are other alternatives). I don't have all the answers, and certainly can't cover all the opinions, so others will chime in here. Just remember, when learning something new there is never a stupid question; though I encourage you to SEARCH the forum as there are some grumpy hawks just waiting around here to swoop down on you if you happen to ask a time-old question. No offense grumpy hawks!
