New discovery for the 1.6l guys

[99 ProLX]

Can someone please clarify or elaborate on the "hesitation" you are experiencing like when and at which RPM's. .. I have the Simota SRI and I don't really experience anything too bad..

Also, do you guys think that it would be worth it to replace my Simota SRI with one of those Cosmo CAI's.. (would I notice any power difference)

 

[Joost27]

ok for me the hesitation was a jerking feeling where if i was between 2,500-3,500rpms the entire car would start to jerk violently and loose speed requiring me to downshift if i was going up hill...The simota SRI I believe is 2.25" so your all set and is why you have no hesitation...you will not notice a difference other then maybe sound if u go with a CAI. I hope that helps you

Actually i find with the CAI if you drive during the day and its like 35 degrees out, then take it out at night once its like ~10 degrees. Your car will run alot smoother and crisper,

 

[Joost27]

that's quite a bit of work for a little smoother running, I don't think it justifies the $100-$200 for a cai and what happens come summer?

I know right!! Its getting warm, and my car is all most frustrating!!! Ive been poot putting to save gas though so ion no if its me or what.

i was thinking hesitation was the vtecish lag u get when u go WOT.

The hesitation iukekini talks about, i call it jerkinjg. my car does it around 3k at 60+ in 4th gear, when u try to sped up w/o pushing it hard enough to downshift, it seems like the engine chokes. jurka lurka

My CAI is custom, i definately did not spend 100$ on it, all you need is silicone couplers and piping of your choice. And when summer comes along, it runs just fine what i was saying was at night it runs better cause its colder outside.

i figured out something, i think why i don't get any hesitation/jerking with my custom made maf pipe is because the maf sits a little sideways in the intake pipe, as soon as i installed it back the hesitation/jerling was gone, does not make any sense to me except for one thing my 2nd oxygen sensor needs to be relocated behind the aftermarket cat that i have on because my stock cat is empty you can see right through it. that's why i had a hard time passing my last emissions test

 

[red95_240sx]

u gutted it?

 

[toronto]

u gutted it?

no it burned out, i think they all do after a number of years. but for me , i blew a cylinder on my last engine and it was running rich so all the unburned gas probably helped to gut out what was left.

 

[red95_240sx]

cool. i wanna burn mine out...

For my 1.6 I have varied intake piping sizes for my CAI, starting at 3" right at the filter which is located in front of the wheel well behind the bumper, then to 2.75" up to the MAF, then 2.5 after the MAF. All I did was cut out the MAF and its pipe from the stock intake and used that little piece of pipe to connect the 2.5" with the 2.75". I haven't noticed any hesitation or jerking unless the engine is cold, compared to when it was stock or to when i had an SRI. The only thing i noticed was that the idle went down to about 450 from 750, but that was easily fixed by adjsuting the idle back to 700. Also the sound is unbeleivable with the varied diameters compared to the SRI and the single diameter piping CAI because the different sized piping creates different tones as the air gets sucked through. Just thought id share that.

I have to say that this is the best way to get around the hesitation problems if any. I did it same way using 2.5" OD pipe but thicker (ID is 2.25"). Two questions thou:

1) From your avitar, it shows the filter is still in engine bay?

2) The amasing sound that you were talking about - how does it compare with a SRI - thats my current set-up. I intend to extend the pipe to the wheel well using 3" bend.
Cheers.

I tried out a 2002(2000+) Toyota Celica 1.8 1ZZFE maf but it was even worse than the original MAF. I didn't have any jerkings with my injen on my 1.5 ZL but i'd figure i'd try it out, see what it does.

Unfortunately the car was sooo laggy. The throttle response was 3 seconds behind before it would move a bit.

I'll post the pic of it asap.
These are the numbers on it:

TOYOTA
22204-22010
197400-2030
DENSO
Made in Japan

12U02

I just saw the GT has a 1ZZFE engine and the GT-S a 2ZZGE engine.

 

[red95_240sx]

well...the main problem i believe is diameter and the seal

 

[island-p5]

1.5 cold air

there are holes in my bumper when the car came from japan.

yes the GT has a completely different motor then the on in the GT-S, which might be ur issue, also did u reset your ecu? And did u make sure everything was sealed right? and also the motor was running well before?

i did post my numbers back a ways:

It was for testing purposes only, as somewhere in the thread you or somebody was wondering if the regular GT maf would work.

Everything was set up properly but it didn't gave any good results.
My car has no issues but i'd thought it could be informative for you guys with the 1.6 and a CAI.

My car is running properly with the Injen cai. No hesitations or rough idleing.
Only thing rough is the 95 durometer awr front mount (screwy)

 

[Joost27]

only the front 95duro mm? lol i have the rear at 95 and tranny, its nothing...haha actually it is bad at times..but thanks for the info and i updated the first post saying that the GT will not work.

cai sounds way better than the sri you don't even have to rev that high to hear it, i love it, car sounds even better with a custom exhaust and headers

so it really solved the problem? has anybody else tried it?
