adding horsepower

Hello,

I have a 1992 Honda Prelude with an AEM cold air intake, and an exhaust that runs from the headers back. I'm looking for ways, such as bolt ons, to increase my horspower because I do not wish to rip apart the block and start replacing stuff do to the lack of large amounts of money. Does anybody have an suggestions for me??

Phil

you could pull your emblems off and put em on an integra :lol:
J/K dood work on your timing, get a throttle body, intake manifold,-should give it some extra nutz

Get a new ECU.

NOS. At least 1000 shot. And lots of stickers.

Well first of if you only have intake exhaust you might as well complete the set and get a decent set of headers to add on. Then id go with some underdrive pulleys to lightin you up and help on timing. Then also the throttle body idea woudl be nice wiht a nice spacer, also intake manifold. You could also upgrade your injectors fuel rail and things along those lines. Defidently dont get all cheezy and throw NOS in yoru car and blow a good honda to pieces trying to be alittle ricer. Also new clutch and flywheel are good add ons. Not saying you will get a huge increase of noticable power, but two very good ad-ons for a well built car.

CRX, can you add a lightened flywheel and an underdrive pulley on the civic? On my E30, the combination of the two is commonly known to cause crankshaft problems.

Yes you can add both its a very good combination because it allows for quick reving. Ive never heard of an irregualr cam wear.

Start with only one header, he doesn't have a v6. :rolleyes:
The pulleys/cam sprocket are pretty expensive, but damn just an underdrive pulley and sprocket added 9 wheel hp on my civic DX. On a lude I'm sure it'd be around 15 or so, and yeah it's noticeable. Don't worry bout the header, that's ~$400 for 5-7 hp... not worth it in my opinion. I love the older preludes, even the non vtec's are pretty quick stock.

Ok 1st the underdrive pulleys are a good idea except fr the crank shft pulley, leave it stock. I fyou change the crank shft pulley then you will be destroying the bottom ends strength.
2nd the "NOS" comment is far off and it is not "NOS" it is nitrous rice boy! I have been using nitrous for almost 3yrs now and my motor is still on the stock internals and has over 130K on it. The compression is almost to spec and that is with 3yrs of nitrous and 130K miles. So don't go around spreading misinformation that you obveously have no knowledge of.

Phil Maybe you should post questions about Preludes in the Prelude-Forum next time!?! You´ll definetly get some better answers there... :wink:

@89B18C1CRX: New fuel rail and injectors are a waste of money on an engine with just some bolt-ons.

i personally really dont think intake header exhaust gives you power it just frees up the air and free up the power you already had. As for going fast your need to
1 strip car
2 New crank
3 new rods
4 new pistons
5 new cams
6 new valves
7 new valve springs
8 titanium retaniers
9 bore throttle body
10 intake manifold and pulleys and cam gears
11 ingnition system
12 injectors
13 stage 3 clutch and take your flywheel to a machinist and shave to 14.7 lbs your stock flywheel is stronger than many aftermarket
14 fuel rail
15 fuel pump
16 Turbo kit with intercooler
17 nitrous kit
18 reflash your ecu
19 blance and blueprint engine
20 tune your engine
21 Take it to the streets by now you should hope fully run some nice 11's

But hey lol what do i know about building a engine i just only went to uti and work for a engine shop
Dont take my word for it.

no offense, but thats just stupid. you say to upgrade all the internals, and you expect the engine to breathe with a restrictive stock box and a small exhaust. i can only imagine the great amounts of power youll get from a turbo system letting out to a stock catback. what you need to do is get the i/h/e before anything else is worked on. and it does add power. if the power was there to begin with, then there wouldnt be any increases.

#'s 9 and 10 are great. lets get an intake manifold, port match it to a bigger tb and then feed it with a stock intake. sounds like a winner to me:bigthumb:

I think you kinda forgot what this thread was exactly about buddy. If you didnt ready he said that he was lacking a lot of cash flow, and your over here talking abotu rebuilding the internals and adding turbo and nitrous? Damn man unless you are lending out the cash flow to do that last time I checked it isnt very cheap to rebuild all your internals. And secondly last time I checked by freeing up airflow and gas amounts is how you increase hp. Therefore by adding i.h.e you are adding hp, for working in a engine shop and saying that you dont need i.h.e, and that they dont increase hp your pretty dumb.:thefinger

He was correct about i/h/e "freeing up" hp the engine already has, all they do really is suck in/expel air more efficiently. On a Prelude these three will free up about 15 horsies.

If ur not planning on unloading a ton of cash then ignore all the turbo and nitrous ideas.

Go for header and ECU

Ok lets clear up something, hp is gained anytime you add more fuel and air mixture into the cylinders. But this extra fuel and air must be the right mixture not too lean and not too rich, Also hp is gained when the cylinder pressures are increased, those are the two basic hp increasers. You can also add hp by freeing up the load on the engine ie: Lightweight flywheel, underdrive pulleys, lighter wheels and tires etc. Just wanted to break it back down to the basics for anyone who does not know:bigthumb:

P.S I personaly think that exhaust frees up hp and intakes add hp, b/c the intake is alowing the engine to consume more air, which is extra air it did not have before , but the exhaust lets the burned mixture of gas and air , that is already in the motor to escape easier. Just my opion though :icesangel

I believe that most people with comon sense should and would agree with you. Basics are basics which include the intake header exhaust first three mods should be done to any car. Following by the lighting stage as i call it, meaning clutch, flywheel, pulleys, cam gear, then you can also throw in a short shifter in there for thos direct quick throws. But basics are basics, but i must say that will only satisfy your needs for speed for so long till you want more!!!
