NON-turbo upgrades??

[Kang114]

Hey guys, Ive heard(and seen) of alot of people doin stuff like "bore -somthing" "stroke increase" "port and polish" new cams pulleys. anyways frankly, i have no idea wtf this stuff is but it sounds interesting. do any of u guys know with these are????

bore something: larger displacement normally. boring out the cylinders of an engine leads to larger displacement, hence, more power. just dont go too big.

stroke increase: not too sure on this myself, but it has to do with lengthening the stroke of the pistons in the cylinders to create (again) more displacement, and more power.

Port and polish: refered to when speaking of heads mostly, which means basically to smooth out the valves, and then match the openings of the valves to their respective manifold perfectly.

new cams: usually going for bigger cams here. this causes the valves to be open longer and wider allowing more fuel to enter and exit the engine, thus more power.

pulleys: again, something else im not to sure about, but it has to do with replacing the big heavy pulleys with smaller lighter ones to decrease rotation mass that engine is spinning and thus sucking power away from your wheels, all without compromising the integrity of the systems being run.

hope that helps

do u have any idea how complicated these mods are or how much they would cost me??? b/c im looking to really beef up my engine before i drop a turbo into it.

ah, to beef up an engine pre turbo, it would be wiser to sleeve your block, get forged rods, and a copper head gasket. when you get your turbo, be sure to get a better fuel delievery system as well. most of the problems that people experience with turbos is because they run to lean
