for the d series fellas like me


found all this stuff of a google search, just post your thoughts, like if you think it works etc whatever.
1. aim your sparkplugs at your injectors [mark your extension with a marker where the open end of the plug is and try to aim it at the intake manifold, not worth over tightening, so only try to aim it k] , I've read some people use washers to angle them at the valves for better low or top end power
2. synthetic oil and correct weight. I use 5w30 all year, because it's warm here in California, F1 cars run straight 30 for qualifying runs I've read [Only valvoline and royal purple have dyno results that I found to prove this, but they should all work]
3. bypass your throttle body coolant lines [disconnect the lines, and run one back to the engine, plug the ones on the throttle body, not sure if this will mess up your idle]
4. insulate your fuel lines, intake pipe [got this off an f1 site, I won't do this untill I'm sure that stuff can't catch fire]
5. high pressure radiator cap, because heat kills power
6.Not to sure on this one, but it's cheap so I'll try it later; In the summer, use a 70/30 mix of antifreeze or 80/20, even all water with some water wetter, water cools better than antifreeze, but corrodes and can crack your block in the winter.
7. advance timing
8. header wrap, [I read it on the label, not sure if it's true], though this one's like 50.00 dollars
9. strip your interior, don't carry a bunch of junk in your car, leave the passenger seat, tools and spare at home. Don't offer heavy people rides

10. los 'n lots of stickers like 10 hp per
Ok, the sticker one doesn't work.

I have these on my car, and for sure, it runs allot smmoother, with more consistant power thoughout the rpm range

 

dude, i weigh 280, and drive a 91 hatch!

some of that stuff sounds bogus, some sounds good. a good tune up oughta make it run pretty good though.

 

some do, but I think they work.i know f1 cars insulate fuel lines, run only water, synthetic oils, bypass coolant from tb, and that's how indexing sparkplugs was born

 

Did you do a before and after dyno test, or is this with the butt dyno?

 

yea butt dyno, that's why I don't want to say I had hp gains.
but I'm using a 70-30 mixture of antifreeze and redline water wetter, high pressure radiator cap too, and my temp sits lower now also. I can take a pic of that

 

#7 and #9 are the only ways to make gain power with tangible results. Well, you can't actually gain power from #9 but you are "adding lightness" which will allow you to make the most of your power.

#1 is called spark plug "indexing", only done on high dollar race motors. Hardly worth the effort.

All of the others would provide negligible gains on a properly running motor. I see where you are going with the theory of it all but results of all those things (minus 7 & 9) would add up to like 1.5 hp on a dyno if at all.

 

If you really want power you need to pony up some money to make the car faster. Stripping the car will do nothing, timing isn't going to do anything much.

 

None of those things are going to make a naturally aspirated D series fun to drive

 

this is not an f1 car all that stuff can go. the antifreeze crap isnt gonna make your car faster, just put some antifreeze in it. your car not runing as hot can cause you to lose power b/c carbon will build up faster leave it alone. i did the bypass coolant hoses but you wont feel much of a difference from that and no it wont mess up your idle. the 5-30 oil is to heavy use 5-20 it will be fine. header wrap does help it keeps more heat in the exhaust and makes it flow faster. water doesn't cool better than antifreeze it boils at a lower temp than antifreeze. ive never heard the spark plug one, sounds iffy though. get a cheap turbo kit and beat it till it dies. GL

 

9. strip your interior, don't carry a bunch of junk in your car, leave the passenger seat, tools and spare at home. Don't offer heavy people rides

i undertand the interiot part but why even try to remove your spare tire and tools which can be essential in a emergency. if you get a flat or if something goes wrong that can be fixed with basic tools then you will facepalm.jpg when you call a tow truck to come pick you up for saving hp Yo

 

Because since you're stripping your interior to make your car faster like a track car. (Which really doesn't do much just makes your exhaust sound louder in-cabin.... obviously if you ever get a flat on the freeway the pit crew will rush to your aid and change the tire in seconds.

Don't strip your interior people.. it just makes you look stupid... if you want your car to be lighter, YOU lose the weight interior doesn't weight as much as you would think.

 

You could do all that...or you could just swap a Z6 or something if the budget is tight lol.

In my harsh college days I did the cheap HP gains. A6 cam in a B2, MPFI swap, Si tranny for better gearing allowing the power to be more responsive. In the end....I just swapped a B series in it. The LS swap was only like 1000$.

 

Okay, I've done these so far
lose some weight, insulate the fuel lines, index plugs, bypass throttle body coolant, high pressure radiator cap, 7o% water in antifreeze with water wetter, synthetic oils and advanced the timing 3 degrees
The only thing I know for sure, because i don't have access to a dyno, is the tone of my car is different and my temp gauge is about 1-2 mm lower than were it used to be.
I want to try the header wrap or vht paint, but I think that ones more of a company promoted one.
The most you can spend here is 50 dollars tops, and if you do a google search, you might find a guy with a new si civic that gained 15 hp and some torque, from all these.
A dc header costs 300.00 rite, and gives about 6 hp, I think it is a good chance. ;]

 

DC is only really good for it's Carb # they tend to crack as much as the ebay knockoffs, and they are like 50-70 used.
Header wrap sometimes causes your header to crack as well, it keeps the heat in so the header is hotter.

 

have an obx ebay one, the guy didn't even ask for the carb number

 

Ok first of all the only DC headers that have been known to crack are the ceramic coated ones and funny enough the same ones people normally say not to wrap

HOWEVER the crome ones that you can purchase have none of this so called cracking your talking about

about the only accurate information you have provided is the fact there carb legal

 

ok first of all honda calls for 5-30 oil on there engines apart from the 2001+ engines

Oh and water dose cool better then anti freeze add water wetter and will cool even faster!

Heat kills power -period- although im not saying run water in your cooling system hell im not making a suggestion any which way just simply stating that's all

The turbo comment LMAO great plan!

You said you have never heard of index spark plugs lmao... not saying that will work either but i though everyone heard of that one?

How will your car running cooler cause carbon to build faster i have never heard about that one before???????????????

 

Uh.... you just said it yourself DC Headers DO infact crack......

 

THe only ONES have been the ceramic NOT the chrome offerings!!!

 

Valvoline synpower > all

 

Yea, I bought castrol sytec yesterday just to try something new
