I'm kinda surprised moving into the japanese market that I cant just order a set of individual throttle bodies... I kinda expected that stuff to just exist (regardless of prohibitive costs). Just staring into the engine bay, it definitely looks that the most to be had for the investment is head work and hotter cams to be by far the best bang for the buck, followed by a proper sand casted upper intake manifold (which seeing the scene, no one is going to invest the proper r&d to do this right), and getting the lower extruded being HUGE supportive work to the rest of the efforts.

Ya I was kinda more curious on others thoughts if a wider bore through the intake runners would be beneficial for NA. I'm use to larger displacement motors where just getting it more air is always beneficial.

technically anything that doesn't directly affect the generation of that power can't possibly "increase" its power. It does wonders for throttle response and dropping the rpms for a quick gear change, but no, no additional power. I know some people that have selected too light of a flywheel and it can affect the idle of the car and alot of hardcore people that scream that it destroys the balancing and harmonics of the engine... but hey to each his own, I love lightened flywheels. they can be hella fun.

 

say could anyone help :
my GD3 fit with A/T transmission
im planning to change original crank pulley with a light weight crank pulley
is there any negative effect.. ?
some says it could brings error on my CVT

how many horse power would i gain on A/T

 

Unorthodox Racing Pulley on a M\T Car! Expect a little less on a A\T Fit! As for the CVT, i really dont know (don't see!?) why it would mess up!

Marko!!

 

so i think it's okay then

eniwei thx for the dyno test graph

 

Hi Marko,
where would you advise to buy the Unorthodox pulley sets? TIA,
Stefano

 

Unorthodox Racing

Unorthodox Racing

Or check out on ebay!!

Marko!!

 

is it true, T1R had already dynoed, before and after changing those light weight pulley and some of the result on A/T were decreased Horse Power ????

 

Honestly, i can not say!!! Just try to serch the forum using keywords ''T1R Pulley A\T Automatic..??''

Anyway i'm gonna try 'em on mine someday anyway so if i feel something, i'm gonna let you know!!

Marko!!

 

wonder who has one of the fastest N/A L15's

 

i need to find a place near OS CA to dyno and drag my fit. i just wanna know what she's capable of. i got

power-
aem cai
ur pulleys
sk2 50mm exhaust
megan header

drive train-
clutchmasters stage 3 clutch
clutchmasters 9lb flywheel
ingalls etd

and various other suspension mods.

any ways, i just wanna see what kind of power im puttin to the wheels. and how fast i can move down a 1/4 mile?!

 

I've seen a guy here who claimed 15.7 All motor L15A!!

It's about what my Neon did after i blew the DOHC tranny and put a SOHC one... Car lost power a lot but was far easier on gas after so it didn't bother...

Marko!!

 

Don't know... High to mid 16's maybe?? My A\T did 17.6 without the rear seats, and with Fujita SRI and Denso IK22 plugs!!

A word about Denso's IK22 on a Fit, Awesome!! You should install them!! About the same gain as an intake but for 40$ Best deal on a Fit!

Marko!!

 

Hi Marko,
I swapped my originals with IK20. Do you think with the IK22 things may further improve? If yes, would you explain me why (newbye asking...)?

TIA,
Stefano

 

yeah i got ik22's. you do feel more power. but cold starts and idles are a bit rough. make sure you let your car warm up before you hit the road.

 

Did everyone buy their IK22s from KW or ebay? eBay sells them cheaper and includes shipping. I'd like to get a set but don't want to buy the wrong ones, unless there's only one kind/model.

 

i got mine from KW.

i just got my UR pullies and clutchmasters stage 3 put in. man, what a difference! a bit more sensitive to drive. but new found power... RELEASED!!! .and much faster revs, up and down.
clutch is new so i cant push it. cant wait to see what hard shifts, launches, and rev matchin is gonna feel like. gotta baby it for about 5 hundred miles first.

 

On the 16 valves L15A, IK22 plugs (or IK20) provides better power because they are shorter then the stockers. Unfortunately, i can't say if stock plugs are limiting power for the 8 valves I-dsi engine!

As for IK20 plugs Vs. IK22... You should'nt feel more power with IK22 plugs as it's only the plug heat range!! For a near stock N\A engine, i think IK20 plugs should be better suited but i didn't tested 'em personately!!

Marko!

 

Personately, i don't have strange problems related to my spark plugs yet but the engine is having one hell of a hard time in those sub zero celcius temperatures... sounds like piston slap when very cold... Just like if i just swapped the Engine from my last 250k km DOHC Neon in the Fit!! But just without the 180Hp...

Marko!

 

Can you guys notice any difference really with adding those bolt-ons? I mean I guess since 10 whp tacked on top of 90 whp is like an 11% power gain overall but does it feel more peppy or just all a placebo?

 

I can feel a difference, not huge, but noticeable. Particularly in the ability of the engine to breathe at higher RPM. The throttle response still sucks though LOL A Blitz TC should fix that but damned if I wanna drop three bills to get one. I have an A-Spec CAI, DC header, Tanabe Touring Medallion a/b installed BTW. And I'm working on a modified upper intake manifold right now.
