need help in understanding english!!!!!!!!!

Just please, dont laugh too much:)) For several days I'm siarching information about engines, more actually about increasing horsepower. In some articles I've read phrases "blueprinting block", "port and polish head", "sleeve block". There is no way I can translate them to my language. Could anyone explain me in more understandable language what all these phrases mean. Thanks in advance.

to "balance and blueprint" an engine is to take very exacting steps in the building of the engine. meaning all the parts are the exact same size and weight. (balanced). People balance an engine because parts that rotate will not rotate truly if one side of that part is slightly heavier than the other. It will "wobble" to be less than precise. Even in an item, such as the crankshaft, which is supported by bearings along portions of its length, the rotating part will try to wobble and cause excessive bearing wear. So, to prevent this, all the parts are carefully measured, and weighed so that they are all the same and they are all correct.
to "blueprint" an engine simply means to build it to some specification. This could be a factory specification, the specifications of someone’s racing engine or one of the ones listed in a book. In its most basis sense, a blueprinted engine is any engine built to a plan.

I would never laugh at someone simply because they don't understand english unless they are acting stupid otherwise. I can explain it further if you wish, but I chose to keep it simple.

Thanks for your fast answer. Now at least one of these phrases is really understandable.

which one is not as understandable, maybe I can help.

You didnt say anything about "port and polish head", "sleeve block".

oh yeah, sorry.
to "port and polish" the cylinder head means to enlarge the intake and exhaust ports and polish them for better air, fuel, and exhaust flow.
this usually involves changing the valves as well.

to sleeve the block, means to insert metal tubes into the cylinders to re-inforce the engine.
The block is overbored to accept the sleeve ... once the sleeve is installed you fit standard pistons (+.000) so the combination of the sleeve and remaining cylinder wall equates to the standard cylinder wall thickness but the sleeve is actually harder than the cast wall.

So as I understand sleeving helps to bring cylinders to factory size. But will the engine work long enough comparing to new engine? Maybe even longer?

Not a very good idea to polish valve ports now. On the intake side, if the ports are too smooth, fuel will adhere to the sides. On the exhaust side - well, after a few trips, the ports will be coated with carbon so it won't really matter if you polish them or not.

Sleeving actually increases the durability and strength of each cylinder. It isn't necessary to use stock bore sizes - you can have them smaller or bigger.

yes, I know that the intake system must maintain some level of abrasiveness to aid fuel atomization, but he asked what it meant.

a sleeved engine will last longer than a regular engine if it is done right.
but sleeving isn't usually done for reliability, it is done for strength, like in race engines.

here's a picture of a shiny ported and polished head.

Thanks for your answers. I knew a little about engine blueprinting, porting and polishing. But sleeving is something new. I haven't heard anyone doing this in my country. Is it expensive? I'm planning to buy 99 eclipse. Lots of performance mods are in my list. Would it be a good dea to sleeve engine or is it a waste of money. The car has ~50k miles.

sleeving is only neccesary if you want to have a lot of nitrous or a turbo with a lot of boost pressure.

Sleeving your engine is used for lots of stuff besides performance. 18 Wheelers and other industrial engines have sleeves because they are rebuilt often. When cylinders get badly scored and you dont have money for a new block, machine shops throw a sleeve in your cylinder, then just resize to match and helps fix the problem. Also Aluminum blocks use iron or steel sleeves to provide wear for the cylinder.

I meant only neccesary on an eclipse.
there are many uses for cyl. sleeves.
