So, with my fit (or jazz in thous country) purchase slowly coming up, I'm purchasing and preparing my mods for it.

Im getting the CVT transmission, which as I understand it, had a great deal of issues, however they ALL went away once the countries with it got the CVT fluid (for years they were only using Z1) So im not worried anymore

Anywho, with a nice 10second-ish 0-60mph on the CVT, i'm looking to milk any power I can. I dont want to reach 60 quickly, I want to zip off the line (to 40?), and THATS ALL. The rest can be slow.

To this end, I have so far decided:

1. Crank Shaft Pulley (Metelogy)

2. Short Ram Intake (home made, next to battery for cooler air)

3. Muffler delete (or straight through)

4. 4-diode spark plugs (irid\platinum)

5. Lightest possible wheels, and 40psi tires. (i love a hard ride, and unsprung weight is where its at!)


Am i forgetting anything without going turbo? Is it worthwhile grabbing an EMANAGE without a turbo? (is there anyhting that can be tuned?) or have honda done a damn nice job?

I also plan to do some cooling mods and get a scangague, but thats unrelated.

Have I forgotten anything?

 

The lighter wheels are the all around best thing you can do for your car and will not stiffen the ride but improve it.... You will also gain better braking , acceleration, fuel mileage, better steering response, control and traction on curves at high speed or bumpy surfaces...... A local shop did an axle back pipe for me with 2 1/2" pipe an glass pack muffler and a friend had one done with straight pipe, the only difference is mine has a more more mellow lower tone and his really snarls.... On the Forced Induction forum Oscar Jackson Junior warned against the solid pulleys and I listen to what he says. I just recently addressed the high under hood heat on my car by installing Run Cool hood Louvers and have had great results.... Tuning tools would be a waste of money unless you add expensive modifications and the ECU does a pretty good job of adjusting to exhaust and intake changes..... What octane level fuel will you use?

 

I'll be using 95\98 Octane fuel, you cant get lower here in Australia. (well you can find 91, but its actually more expensive as our 95 is 10% ethanol, which im OK with)

The Mythelogy pulley is actually Semi-dampened. there is a ring absorbing some of the vibrations, just not all. Also, its made from the lighter, less resonating, softer alloy (6016? I believe?) which, despite rumor, is better in this application than 'aircraft aluminium' (7015? I forget the numbers). Also leonine has had his on since 2007 and has no issues.

Either way could you direct link me? I cant find the solid pulley thread you talk about, thanks

I'll be going a straight pipe, but I agree its a little loud. I'll likely get the smallest muffler available for the tip.

I have also recently decided to get my header SLIGHTLY bored and polished, what sort of company do I look up for that? I only plan to get a couple of mm shaved from the inside, then polished.

I want to do every possible power modification without a CEL. Nothing so far should throw a cell should it? What else can I do?

thanks alot Texas, you've been very helpful, link me to that other thread

 

the best mod that helps acceleration, braking, handling, fuel economy and even adding increased reliability is.................

WEIGHT REDUCTION

start stripping (free if u do it yourself) and replacing heavy parts with light ones (expensive )!!!

you might have to sacrifice comfort though

 

Unfortunately it'll be a daily driver, so that wont be happening. At most, if they come out in 2 halves, I may remove the larger half of the magic seat.

 

It's like 2:30 AM here and I am half asleep and can't find the thread that you need in regards to the pulley issue but it is in the Forced Induction forum in regards to the Kraft Werks Super Charger kit but applies to all Fits and has to do with cam timing somehow..... I am not sure what type of stock header you have on the engine in your car but on the 1.5 we have here the header is tube type and not likely to be able to have any beneficial machining done on it.... We have found that ethanol does nothing to benefit power or fuel mileage because it requires more of it to make he same amount of energy..... I have seen some uTube videos of little 1300 CVT cars that appear to be capable of romping all over the cars we get here..... All of the safety legislation due to the asinine drivers here have loaded so much weight on cars here that they are much heavier than those sold elsewhere.... leonine is like a guru to a lot of us here and if he is still using the pulley you are speaking of there should be no harm in doing so.... There are a lot of us that do things to our cars that someone ends up telling us will do harm but somehow get away with doing without suffering the promised catastrophic after mass.

 

I'll try to find it.

Do custom headers normally cause CEL's? I keep hearing about them, but some people seem fine.

 

I have a super charger and am using the stock exhaust except for the axle back..... I have only seen my CEL a couple of times and it was after messing with the intake and forgetting to hook up the wiring on the air intake sensor and a vacuum leak from a rat eating a tasty silicone hose on the super card system that came with the S/C kit.

 

they will only cause a cel IF they also delete the cat (or if u let a moron design /install the header)
ever hear of extrude honing?

 

that has NOTHING to do with what the OP asked

of course u will get a cel if u "forget" to hook up all the sensors!!!
lmao

 

leonine??

to base results on just ONE person is asking for trouble
how many miles has he put on with the pulley? how does he drive? popularity DOES NOT EQUATE TO CORRECTNESS (usually the REVERSE IS TRUE i.e. more people eat at mcdonalds vs being a vegan, couch commandos vs gold medalists etc)
no harmonic balancer WILL absolutely hurt longevity (even if it means your engine will last for 400,000 miles vs 500,000 miles, IT WILL HURT)


to base your judgements on this forum alone is ludicrous (dont even listen to me but look up reputable sources i.e NOT THE INTERNET FORUMS)

 

OJ jr merely glanced at the subject of a pulley in like ONE SENTENCE

talk to endurance racing WINNERS not the forums (why not just go to the local mall and ask the food court about medical or financial advice? that is just like forums)

 

Yeah you are right about that.... My pain medication was kicking I guess and might have had some influence on the way I was interpreting things and responding to them...... I am sure you derived great pleasure in calling this to my attention.

 

Hardly one person im going on, and even if I were, his Fit is boosted, he has had it for MANY years, and he can feel free to chime in and talk about his driving habits; besides Ive read every thread on here, and done my share of googling about the issue; I came to several conclusions.

Lighter pulley = less vibration already. Go to a drum kit (cymbal) and replace it with, say, cardboard. No matter how hard you hit it, the vibrations wont transfer to the drum stand. The same goes in reverse, replace it with a thicker metal and hit it, and the resonance will travel through the stand much worse than the original cymbal. This also has to do with the hardness of the new material. As such, Mythelogy have used the 'softer' aluminium, and NOT 'aircraft grade aluminium' (which sounds good, but resonates BADLY), they also DO have a harmonic ballancer on their pulley, it doesnt extend all the way through, but as anyone with logic will tell you, it doesnt need to, to catch harmonics and what not. Softer aluminium, semi-dampened\balanced, lighter, after reading as much as I have Im not too worried.

I wont be deleting my cat, I dont want to remove that much I just wanted to slightly tweak the header (there is obviously SOME restriction there) as different headers ALONE are showing up to 15-10HP gains (at their best).

As for basing my judgement on forums alone, yeah thats stupid, everyone needs to use their own logic and common sense, however to use this as a primary information source is fantastic IMO, who knows better than hundreds of other owners? The engineers MAYBE, but we cant talk to them one on one, and they have to abide by cost restrictions so often not even they know better.

OK, so i'll add bore\polish my header to the list of 'things to do'.

 

well, after much question dodging and 'templaye' replies, i finally talked to someone at Mythology and they confirmed the rubber dampener goes deep. He estimates about 3\4 of the way through.

So, yeah, it is more than 'slightly' balanced\dampened.

 

40 psi in your tires jesus i hope you dont get a bubble. also kraftwerks sells some spark plugs that gain a few HP's.

you can upgrade grounds, header, exhaust

not sure if straight through would actully gain, hurts low end

 

...Ingalls torque damper
...Innovative motor mounts
...Blitz (or some other) throttle controller

 

those dont really gain any HP numbers, i think thats what he was looking for

 

OK, a little off topic. My wife's Nissan Sentra has a CVT. Together with it's 2.0L engine, it feels very torquey, and is ALWAYS at the most appropriate engine speed. Very cool.

Apparently Nissan has had some trouble with them. We just got a letter from corporate stating that the warranty was extended to 120,000 miles and 10 years.

 

watch the skunk2 vid on head porting and do that lol
