600?!?!

sounds like a steal.

several places quoted me about 1200 to rebuild my ka when it blew.

is that for jsut the labor or something?

The actual parts cost is very little for a rebuild. Bearins are pretty cheap. Rings are 100 for a set, full gasket set is another 200 or so.

If you need any additional machine work... it starts to climb. Polishing crank journals cost about 50 bucks. Grinding them down cost more. Honing cyl walls is around 50 bucks as well.

If you want someone to assemble the block for you, it will be even more money. This is where it starts to add up alot. Labor is the killer.

Buy all the parts you need, get the necessary machine work done and assemble it your self. This is the most cost effective way of rebuilding. Rebuilding an engine is not so hard. You need proper tools like a quality torque wrench, angle gauge for torque-to-yield bolts, piston ring compressor, installer, etc. You also need a plastigauge to check for clearances. Also might benefit from a feeler gauge. Both very cheap and easy to use.

Labor is the killer. I had mine rebuilt by my shop for around $3000.

if you are only looking for 300-350 whp, why rebuild at all? the stock bottom end can easily take 400+ whp reliably.

Are you wanting info for stock rebuild or for more power?

I think he means stock rebuild... but I might be wrong.

I'm not sure either. He asked for rebuild cost, and for 300-350hp. But stock internals should hold that much anyway, right?

ILikeMy240sx: What internals are you running on your set-up?

stock blocks can handle 300-350 easily. Enjuku had a stock block handling over 400 a while ago. Not sure what the final number was on that car or if it finally blew.

Either or, a rebuild back to factory specs isn't a bad idea. I will be doing that operation sometime this spring once I have some money together. All I really need is to have the block cleaned up and get a few things balanced. Aside from that, I'll be doing the big stuff myself. I've done a bunch of SR rebuilds now, so I find them overly easy.

i was considering a sock rebuild but im looking into using cp 86.5 pistons stock compression eagle rods Power Enterprise F1 Black Metal Con-Rod bearings and main crank cap bearings and have the block cleaned. i know the stock bottom end can handle my power goal but i want to start fresh the car will b used as a weekend car and i dont want to spend so much money on power upgrades to have it last for a couple of months. i want it to be reliable.

maybe he wants to be sure its really reliable.... IE leaking piston rings and such. its not a bad idea to tear your motor down and clean it up before you stick it in... its so much better doing it right the first time.

and as for my rebuild.. ILikeMy240sx is right... parts are cheap, the thing that would be expensive is labor, but i did it al myself, pretty simple.

i got my sr out right now and have been looking for a local shop to machine it. in the mean time i have been seriously considering not an all out rebuild but jsut freshening up the engine.....bearings, rings, seals, chain an water pump. some i could probally do my self.....but this one is gonna have the big power and having a professional do it is jsut piece of mine. i have a couple of ka's i want to ruin first before i mess with the imported engine.

Hmmm. I'm finding a $600 rebuild hard to believe. Either way I will be rebuilding mine over spring break for my new toy...... .86 GT2871R

I'm just paying for parts right now. I'm enrolled in a high performance class, so I do all the labor myself.

Tell me about it. I'm hoping to leave my job and start working at an engine shop, or do rebuilds in my spare time. My buddy races dirt bikes and wants me to start doing work on his engines.

Try juggling all that and having to pay two speeding tickets or going to jail and not having any money for those tickets. I think I'm FUBAR'd

what do you guys think if i just buy a long block and have it machined. then i rebuild it myself a short block will b easier and faster then pulling out my engine dont you think. then wait till i have all my performance parts or sr blows up which ever comes first then just swap out long blocks. also how hard is it to rebuild a motor ill b doing the work in my room since i dont have a garage.
