modifications

Hi , my civic 88 1.5L. wants more horses, if I put:
cam pulley, cranck pulley, and power pulleys (aall this from unortodox), Air cold intake, iridium spark plugs, nology wires, new clutch,
How many horses is the gain?

And some know the price of one ligthened flywheel and the gain on horse power.
And information about the rigth clutch??

I want to get about 180 hp or more, without a turbo or swap engine, please help me to do this.

Maybe an MSD 6A could help ?

Thanks

Wow... well, unless you do some serious rebuilding it will be pretty hard to get those numbers from a 1.5. But, yeah, you can get a few horses from the cam, gear and pulleys because supposedly the crank works faster. You gotta keep an eye on your electronics though. I've heard many stories of people with pulleys killing their cars cuz the alternator won't charge the battery fast enough. In my case, it was bad mechanics, not parts. I now have a lightened flywheel and exedy street/strip clutch but the gains are not very noticeable even though I've balanced out the engine dynamics on both sides. Here are some links though...

good luck

yea you will need alot more than that if you want to damn near double the amount of HP the motor is currently producing. all those mods you mentioned youd be lucky to break 105hp.

Just my input, DO NOT get a lightened crank pully (or any pullies for that matter) your car will not last more than 10k more miles with them on.

The greatest poweradder you could do to your 1.5l is the MPFI swap. the tech article is on http://www.4thgenerationcivic.com/ then do the bolton thing and youll end up with low 100's....110 if your lucky (this is bhp, not whp)

I have to call BS on that one, dude... sorry. I've been using the Unorthodox pulleys on my ride for 40,000+ miles and still going strong...

the light crank pulley is 4 times lighter than the stock, which means youve removed that much weight from a balanced rotating assembly. This frys your bearings. Ask my sis. Her engine siezed from the fucked up bearings after about 15k of hard driving on her old civic. Her engine had 50k miles on it. Theres no way the bearings could have looked like they did w/o something adding to the damage.

That makes sense I guess, cuz my tranny bearings fried up but the tranny had 181k miles when I replaced them at the time of installing my ACT streetlite flywheel and Exedy clutch. But I still drove the car to the shop. Hopefully, the rotating mass is more equal now with the lighter flywheel... perhaps I should've gotten the 8lb. one :dunno: Eventually, I'm just going to use the rex for weekend abuse anyway.

thanks, everybody for your response,
Headers may be help to get more power, and a swap my 4 shift tranny for a 5 shifts.?
whats the difference between bhp and whp

This days has been really hot more than 102F

you have a standard hatch (since you havea 4 speed). The best two mods you can do to it are swap in an 88-91 civic/crx si 5 speed tranny and do the mpfi swap. Thatll drop close to 3 seconds off your quarter mile

Thanks alex, on hp´s do you know the gain?

headers won't help a whole lot, they help more with the more power you have.

your at like 70hp right now....youd be right aroudn 90 or 95...with boltons youd be at around 105 or so. These are guestimates so dont hold me to them

Just my input, DO NOT get a lightened crank pully (or any pullies for that matter) your car will not last more than 10k more miles with them on.


:grinno:

shit believe what you guys want, but i saw my sis's bearings and i use as hell aint puttin no damn pulleys on my car

Your sisters car had an aftermarket crank pulley, then bearing problems shortly after and you assume that the crank pulley was the downfall of her engine then????

1.5L so you either have a Standard or a DX, either way you can get maybe 5hp from the mods listed, so you will be at about 78 or 98 crank hp, subtract 10-15% for whp.

CAI ~ 5hp w/ MPFI engine, less w/ DPFI engine
cam pulley ~ 0 w/o dyno tuning
cranck pulley ~ 0 (same effect as lighter wheels)
iridium spark plugs ~ -5 to 0 depending on the condition of your ignition system, you may loose power
nology wires ~ 0
new clutch ~ 0

This all assumes you are replacing good stock parts.

the light flywheel and racing clutch can be found on ebay for a pretty good price. Get ACT if possible. For the Plugs and wires just go to autozone and get a set of bosch wires with NGK plugs. Then order an MSD dizzy cap and an MSD ignition coil too. And if you dont have them already just get a simple short ram intake and a full catback exhaust with a header. And the MPFI swap with a DX or SI tranny are a good idea too.

Yeah, my sis put an aftermarket crank pulley on there. The bottom end had never been opened, and there had been ZERO fuckin problems. 14-15k miles later, her engine siezed. The bearings had worn enough to cause a nice gouge. She didnt drive it hard except at the strip (probably no worse than you drive your car) and it got fucked. You explain to me how an untouched bottom end gets beat like. Believe what the fuck you want SiZ, but for me seeing is believing and i saw it.

How many miles were on her engine? Do you know how well it was cared for prior to her owning it? Who installed the crank pulley for her?! Do you know how many variables there are? Some Honda motors don't even have a harmonic dampener from the factory.

If installed properly, your sisters crank pulley quite likley isn't the reason the motor pooped out.

BTW - No one drives their car harder than mine. ;) Well, probably a few people but mine sees 8k a couple times a day.

If it fucked her bearings it was cheep and unbalanced. The pulley is unsprung weight, meaning it has nothing to do with the balance of the rotating mass. If the pulley is not properly balanced then it will throw off the rotation and kill bearings.

I would suggest to ditch the 1.5, They are not power making engines. Get a B16A if you want simple swap with more power, or go like B16 or H22 or something if you want more complicated. You could throw every aftermarket part at a D15 and it wont get to 180hp.

You could throw every aftermarket part at a D15 and it wont get to 180hp.

You'd like to think so, wouldn't you?

well, If you can do it more power to you, realisticly I dont think it would happen. Well not for less than a motor swap would cost anyway.

Homemade turbo? $800? yeah, thats what I spent on mine, the D15 lasted 2 weeks, but at 12psi it had to be more than 180hp.

It blew from a siezed wrist pin @ 4krpm, NOT detonation.

He said he did not want to turbo, so i was not including boosting. No dout in my mind you could make 180 with turbo or supercharger, but without I dont think you could without throwing gobs of money at it.

I think it could be done N/A, it would be difficult, but a fun challenge.

Or you could just copy someone, I'm 99% sure there are a couple guys from H-T who have done it. The D15 has a better R/S than the D16, so it should be able to handle the required high RPMs.

if I rebuild my engine 1.5L std. with new JE pistons,
how much power I will gain.

the engine had ~50k on it when she had phanstasm (local performance shop) install it. They are halfway fairly reputable, but who knows? The previous owner was a 35 year old secretary. She had maintence records from every oilchange and such. You may be right, there are other factors, but I will choose never to use aftermarket pullies on my car

my boi installed a lighter crank pulley and now he has charging problems from the battery.

you could get 180 whp from a d15, go y8 or z6, pistons for at least 12.5:1.. and nitrous, Bisimoto or similar header, and built head, cam, etc. Prolly wouldnt be able to run on pump gas. Check out EXOSPEED.com they have some real nice non-vtec head packages for d-series.

if I rebuild my engine 1.5L std. with new JE pistons,

not much. it would be cheaper to get p29 pistons from a ZC/d16a1.. i cant remember if you can use them in a d15 tho...

yeah you can, same wrist pin (19mm) and bore (75mm)

yeah i thought you could...

also.. forget about ingniton mods. On fuel injected hondas upgradeing the ignition is a waste of money until you are pushing 300hp... Iridium plugs do nothing for performance. copper is a better conducter, just because iridium cost more people think they add hp. they dont, they are made for longevity...

i sold someone iridium plugs for a crown victoria when i was working at auto zone. My boss shoulda kissed my ass for that. Especially since they were 12.99 a piece. Thats 103.92 before taxes!

holy shit 100 bucks for plugs?!?! damnnnnnn

yeah i shoulda gone up to my boss and been like see i deserve a raise cuz im such a good sales person and smiled all gayly at him

I'm using Denso Iridiums right now with no problems, they were just cheap for me.. My other plugs were TOAST so I picked these up off a friend for $10. :)
