Honda Car Forum

i have a 94 accord V-tech and want to get dirty with the car, do everything from top to bottom... can someone explain to me how the entire engine works or guide to?WOULD LIKE TO THANK THOSE THAT TAKE THE TIME TO ANSWER MY Q..

Go to an auto store and buy a repair manual.

What the individual parts do is easy however making big numbers out of a Honda start at the bottom rather than the top of the engine. The two biggest power adders you can add are a Turbo and NOS which give you almost unlimited power. The problem is do you want to just start the 1/4 mile fast then blow an engine at the 1/16 mile or run strong to the 1/4 mile.

Let me say an engine is just not parts that can be replaced individually for more power. Every part in your engine works with every other part and replacing or upgrading one is going to have a positive effect on one part and a negative on another.

Any engine from the manufacturer is not rated for a turbo and if you try to put a 20psi boost on a stock engine you end up with scrap metal very quickly. On the other hand if you build the engine internals (such as pistons) to handle more power you can do so safely and reliably. It costs more, if you wanna do thing the right way it usually does.

If you want quick bolt on relatively safe power consider a cold air intake, low pressure exhaust, ecu, etc...

As for pulleys they lower the drive ratio on the engine to turn accessories such as the alternator allowing the engine to rev quicker.

Camshafts change the way the engine feeds and breathes changing the way the valves that control air intake and exhaust from the cylinder act.

Pistons are a more extreme mod in that they can help your engine handle more power and even increase the displacement and compression of your engine. Though the wrench time and expertise needed is much more.

There are many options to list on this one. I could write a novel on this but do your research first and decide on what your goals are. You could make 800 HP if you really wanted to but there is ALOT of work involved. ALso you can just make a daily driver with a little more kick. Do some research and set your goal. If you want high horsepower go with a turbo, if you want something simple go with a TUNE UP FIRST, then headers, some kind of air intake, catback or full exhaust from headers back, and a chip for your ecu to help with the air/fuel mixture etc...Good Luck

i would have to write like a 5 page essay to explain that. its just if you just throw those ramdom parts out there there is so much involved & included that id getoff subject and explain how a car engine works mechanically. so yea thats what you shuld ask- how does a engine including all compents work togherher|? or sumthin to that nature

they make the engine work

Come on, of course.

If the topic poster wants to really know how an engine works there are many tech schools (matc.edu being mine) not to mention books to help. Also about.com.

P.S. If you just want a post to stay current so YOU can learn just type "/bump" with out the quotes. Rather than try to make someone else feel as stupid as you.

Yes, engine design has its own complexities...beyond what I or most fully understand. However, in simple, conceptual terms, an internal combustion engine is a kind of an air pump. Improvements/modifications that make that pump more efficient tend to result in increase performance. However, the journey to greater performance is fraught with peril if one goes willy-nilly about it.Conceptually, the following mods impact peformance in the following ways:- cold air induction (CAI) -- increases air flow by elimination of restrictive stock resonator intake box, increases airflow by high-flow filter, & increases oxygen density by induction of cooler air from outside engine compartment- throttlebody spacers -- increases volume of air/fuel mixture in intake manifold, provides for a more complete mixture of fuel with air due to increased length of flow.- thermoblock spacers to throttlebody & between top of block/intake manifold -- provides greater heat isolation to intake components, resulting in cooler, denser intake- thermal wrapping (insulation) material -- reduces convenctive heat transfer from engine block/transmission to intake componts, produces a cooler, denser intake volume.- iridium, & silver (Nology) plugs -- hotter spark for any given voltage, more complete combustion.- grounding wire kits -- provides better grounding that enables ECM to provide optomized ignition.- ECM (chips / chipsets) upgrade modules -- provides for remapping of air/fuel/valve timing/transmission programming, etc., to optomize performance- forced induction (supercharging, turbocharging) -- increases density of fuel/air mixture- variable volume induction (aka, VVI)-- provides a mild resonance tuning, creating a mild overpressure against the intake valves. AEM's V2, CAI system provides this feature (small gains)- performance headers -- provides similar resonance tuning effect as VVI, but at the exhaust side...helps to pulse scavange exhaust gases, reducing backpressure.- performance catalytic converters -- reduces exhaust restriction...cats often are a significant point of flow restriction.- catback exhaust systems -- reduces exhaust by (sometimes) increasing diameter of exhaust piping, by elimination (sometimes) of resonators & midmufflers, and by (sometimes) employing high-flow mufflers (flow-thru type in lieu of 'U' path mufflers)- underdrive pulleys -- reduces 'parasitic' taxation of engine power by underdriving engine accessories (e.g., alternator, etc.), for slight performance gains.- high flow fuel filters -- used in conjunction with forced induction to increase fuel delivery rate to engine- high lift cams -- increases valve lift duration during high rpms, which in conjunction with tuning produces hp gains- performance & boredout throttle bodies -- increases internal diameter for increased flow- porting of heads -- increases flow on intake & exhaust- high compression (aftermarket) pistons -- increases density of charge, for more hp.- precision balancing of crank, rods, & internals -- smoother running, and potential for safer, higher RPMs- Nitros Oxide (aka NOS) -- spray induction for increased intake charge energy for large, but short duration perfomance gainsThe above are many, but not all performance mods available. However, with the exception of adding CAI, exhaust upgrades, and 2-3 others, performance specialists should be consulted...it's possible to do serious damage to an engine otherwise. Many of these modifications interrelate & require a healthy understanding of internal combustion engine design to enjoy their benefits.

Hard to read but as far as I know very accurate "Many of these modifications interrelate & require a healthy understanding of internal combustion engine design to enjoy their benefits" in particular.
