Are pulley's worth it??

[mattilude]

Hey what kind of gains can I expect from some good AEM underdrive pulleys on my 93' SI Prelude??

[Prelewd]

You will end up with.. let's see.. 160 crank horse power

[juicy19]

you rev quicker basically. I don't know if there's a huge difference. Less parasitic drag, quicker acceleration. They look nice too.
I've got the unorthodox racing pullies

Your stock crank pulleys act like an engine damper with their rubber mid lining. You are compromising your engine's stability (and life) using these all metal 'racing pulleys'. Plus you'll vibrate alot more. Honda dampened their stock pulleys for a reason. You're pretty much asking for trouble.

Then WHAT else can I do to my H23 SI prelude.. and DONT say H22 please!! I dont have that kind of budget.. I already have a cold air intake.. I want some more HP and Torque.. where can I go for some performance?? not a big turbo or nitrous fan either.. i'm an all motor guy

Nothing really, if you don't have the money. You can take out the A/C and P/S.. Won't help comfort much though. I would suggest saving up some money, and having some machine work done. Port and polish is always nice. Sleeving.. lighter weight/stronger (forged) internals. Dare I say.. Turbo.. oh wait.. you don't have the money.

To extract any power out of a 4 cyl. engine, you need to have money..

I'm glad you asked. Since you already have a CAI, I would suggest investing in an exhaust system. Nab the RSR Exmag. If you have money after that, get some new tyres (and wheels, if you want) and if you want, a CF hood and trunk lid. If you are feeling brave and think you're competent enough, get an SAFC and start tuning away.

Money is really what it's about. You just can't add a 20 dollar muffler and think you're gonna get anything out of it.

ITS NOT WORTH IT!!!
SAVE UP FOR FORCED INDUCTION!

Sorry, had to say it. Sadly, it does cost A LOT of money to get noticeable gains from an NA car. Your best bet is to start saving up now (every penny counts, trust me), and eventually slap in a supercharger (if you don't wanna worry about maintenance and strengthening your block), or a turbocharger (sometimes cheaper, but more maintenance-bound). personally...thats what i'd do. with what i spent on my CAI and headers, plus the tools to install the headers (i did it myself), and all the other money i had to dish out when i screwed up, i'd be halfway to the turbocharger mark by now

Get lots of NOS stickers, and a huge double decker wing.... that will give you about 100 HP... haha, j/k. But seriously though, since you already have the intake you could have your throttle body bored out and get bigger injectors, then upgrade the ignition, headers, & exhaust.

[AcesHigh]

Just for the record... the stock Prelude ignition system is adequate until nearly 300whp. And larger injectors are useless until you have the means to control them (... and an SAFC is not the equipment to control them).

I am going with NA.

lsd and a stage 3 clutch

Prelewd is absolutely right. Pulley's won't add any hp but they do take a little stress off the engine. I know everyone downs it but n2o is actually one of the cheapest methods of achieving hp for the money. The only problem is that a dry shot (which is about what you can afford) isn't the best thing for your engine if you overuse it. A weight reduction (cf hood and trunk, back seat, a/c, spare tire, etc) is actually a effective and cheap way of improving quarter mile time. Good luck with going NA though. I have a lot of respect for racers that go all motor because its quite a difficult thing to do. Its so tempting to put on a turbo......

[Prelewd]

Just would like to note that the backseat weighs a whole what.. like 5 lbs? If that.. Take out your scissor jack and you'll reduce more weight than that.

[AcesHigh]

Racing pulleys actually add more stress to your block and reduces engine life. And yes, nitrous is the best bang for the buck (even moreso than a turbocharger).

Your radio weighs more than 5 pounds. Your backseat weighs prolly about 20. Don't quote me on that or anything but I know that it weighs more than 5lbs though Prelewd is correct in that taking out your jack will take a few pounds off. Just pray you dont get a flat or you will be wishing you had that jack and the spare!
