New discovery for the 1.6l guys

[Joost27]

well yeah, it helps make it smoother, not faster, i think only a turbo will allow that to happen. Although, I did see a slight gain in 1/4 mile times due to the smoother acceleration.
So, your still getting hesitation and jerking when accelerating without down shifting?

 

[red95_240sx]

no, there is no hesitation. but a lil jerking like its choking. this is only around 70-80mph.

I tried the MAF swap It works really well. The MAF needed Is for the 2ZZGE 1.8L engine in a Celica GT-S

I had a Cosmo Racing CAI and got the DAM CEL light I Liked the sound and seat dyno power but I hate the light so It's gotta go. with the stock tube runs out nice and no CEL I'm also Getting rid of my Cosmo Racing CAI at

yeah my light is still on, but it runs right.

Looks like one heck of a relocation for the MAF. Im gonna watch it...

any hesitation? i'm interested.

No hesitation with the stock tube but some with a CAI on I think it's the size it's a 2.500" tube it realy needs to be 2 1/4" It makes the ecm think it's getting to much air and kicks a CEL light. so it thinks it's running lean and I don't have a wide band to see if it realy is.

 

[red95_240sx]

i think he meant with the toyota sensor.

 

[coopdog]

My bad
With the 2zzge sensor in it runs really nice. but it's still a 30mpg 1.6 not a real beast. but worth the mod make it alot nicer to drive. IMO

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.

 

[Joost27]

well the reason why you didn't get any hesitation with that setup, is because you had the MAF sitting in the stock 2.25" piece of plastic, so the air got squished down to that size pass the sensor. I really don't think anything bigger then 2.5" is needed. 3" is just overkill for our tiny motor.

what about a 3" bend on the end of a 2.25" SRI?

any CEL?

 

[ottawaprotege]

No CEL from the MAF, and as far as 3" being overkill goes, it's not really there for performance it's mostly there for sound, having that 3" section really gives the intake a throaty sound, you can't even hear my exhaust over the intake.

 

[Joost27]

still overkill either way, the 2.5" Injen is loud as hell too, idk 3" just seems big, but if thats what you are wanting, and its working out, more power to yah.

red pro... why would you do 3" the point i was making is that its not needed, 2.25"-2.5" is PLENTY for the 1.6liters of fury. also if its right before the maf, im pretty sure a crap load of turbulence will be created at the different sized pipe intersection and probably make it run crappier.

 

[red95_240sx]

its a 3" elbow on a 2.25" SRI though. the MAF is at the 2.25" area.
my frien dlost my 2.25" elbow

 

[Joost27]

well, if you want the elbow, and you lost the other one then sure use the 3" if thats available for you. Looking at it from a performance aspect you will not see a difference.

 

[red95_240sx]

u mean between 2.25 and 3' elbow?

 

[Joost27]

yes, but if its what you have laying around and you lost the other one, it should work fine.

what about a 3" bend on the end of a 2.25" SRI?

i have a 3'' bend after the maf pipe 2.25, it works fine no hesitation with a custom made 2.25 piece of pipe that i had made but i changed over to the plastic tube from the stock air box and now there's hesitation, the only reason i changed it over is because i think the custom made piece leakes , so i'm trying to get the toyota maf.

 

[red95_240sx]

haha. did i unplug the batt.?
