to really make maximum power with what na products are out there i think the best results come from:
weapon r race header
spoon b-pipe and spoon n1 axle back (dont really make a differance who you use cause they all make about the same numbers.)
weapon r intake manifold
cai (probably prm since they posted some really good numbers)
t1r crank pulley
kraftwork spark plugs
lightened flywheel (cant think of the company who makes one)
type one jdm reflashed ecu.

all that should be good for about 120hp but you really have to shell out some money for that ecu....

 

and i'm betting that ecu might not let it pass smog, huh? i hate being from CA sometimes.

 

most definately not created for smog. its a 24 hour enduro tune.... max safe power.

 

man, oh well, i need to keep in mind that the fit is not a sports car but it sure handles like one!! it's just a fun car to drive.

 

The WeaponR race header is right out too, it deletes the catalytic converter.

 

ugh too many weaponR references. sorry but they make shitty knockoff products with horrid build quality. especially that manifold, wow, liabilty!

anyways I searched but I see only 2 total references to Extrude Hone [http://www.extrudehone.com/]. I sent my previous car's intake manifold to them and they took out 3.5 pounds of aluminum (taking it IIRC from 120cfm to 193cfm). I haven't pulled things apart so its hard to tell if the extra volume (w/o boost) will help with the upper end or just kill air velocity. I still have a gift certificate with them, I was kinda hoping someone has already dealt with them as I hate to be the victim of discovery. I'm sure with boost this would be a godsend but NA it might just be better served with a good port matching.

 

what's your basis for this?

 

the fact that people have made ok power numbers with this setup.

its really all that is avaibable at this moment.

 

I had a turbo on my old civic. I liked it a lot but there was to many probloms with F/I. Even thou the fit is slow I'm going N/A with it. But wished there was more out for N/A.

Is weapon-r the only one that make the intake manifold for the fit, can't find anyone else that makes one..

 

Jdm Reflashed ECU? where do i look for one of those?

 

Personally i think L15A power resides in ports polishing, cams, a good intake manifold and a tune to go along...

As cat cams makes Cams we now need a good intake manifold with velocity stacks in it, ports polishing and a good tune... a think 120 130Whp is possible with some creativity and $$$!!

Marko!!

 

Catcams are only $460, but I've heard mixed reviews! They'll make a huge difference, but scared to be the first. Also Gude will do a full head package ( port and polish, cam ) but his is $1250.

My goal
SRI (done)
IK 22 spark plugs
lighted pullys + flywheel
headers
B pipe
HKS HI power exhast
Tune ( reflash or somthing)
Intake manifold

 

grude? do you mean gude?

you would maybe call opak racing to see if you could order the reflash from type one.

the enduro spoon gd3 is only running a full exhaust, spoon air filter, oem internals (the class they race in doesnt allow machined internals so tey weigh all oem parts untill they find a perfect balance) and a type one ecu tune and they are laying down 123hp to the wheels.

the numbers are there but they are hidden.

no one ever talks about top fuel's gd3 which has head work and a tune and lays down 142hp N/A...... it costs 7800US though.

 

oops, my bad

If only I was rich! lol Head work def seems the way to go!

 

I emailed OPAK, lets see what they have to say.

 

The Spoon racecar has high numbers. But I'm pretty sure they don't have PS and AC. (or either) The engine's blueprinted. Spoon engines are really supposed to be blueprinted.

 

Yeah, an extrude hone can be really helpful on FI applications - especially ones with little to no aftermarket . . . But it wouldn't be a very viable option on the Fit since the top half of our IM is plastic.

And an extrude hone doesn't do anything about the mega-long runners in the design. For real NA power you need to bump the powerband up higher, which means shorter runners. Although I'm not sure how you'd shorten the runners without relocating the entire throttle body assembly.

 

still need an ecu to be reflash

 

port and polish will make you run lean.

i wonder if running the aem piggyback is more efficient than the greddy emanage?

 

"Increased" HP on a dyno is an artifact of the dyno process. A lighter flywheel/drive train does nothing to increase HP, although there may be slight increases in acceleration due to less rotational mass. I'm not saying there isn't any performance gain, but it's not due to increased HP.
