overkill 62mm itr TB???

Just a quick one..

Mods --> b16a2
- 4-1 jdm itr headers :(
- plazaman/dynodave cai
- bc specIII 2.5'' catback
- metal cat
- skunk2 IM

with those mods.. would a 62mm ITR TB be suffiecient?

I'm looking at a tune later on down the track with better headers and afew other things aswell.. but not atm..

but for instance if i whack the TB on would it make a difference??
I'm not looking at any power gains or improve response doing this.. i just dont wanna LOSE power or response if yah get what i mean?

or should i wait til im ready for tuning or scrap the itr TB all together?

and also.. will a 62mm tb be sufficient enough for a tune with head work n shit done?

thanks Du

If you don't want power or response gains why bother considering it then? :confused:

It will go well with a set of CTR or ITR cams. We made decent power mid those mods

62mm is fine. Recommend ITR cams. A b16a we did with your similar bolt-on with ITR cams made pass 105kw atw.

i guess this mod would help with future mods. As future mods might have to wait a little longer why not chuck on a mod that i have lying around?

get it?


then the TB would help with other mods like cams like fatboyz n benson said..
(when i have the cash for these mods) :thumbsup:

lol yeah. im not expecting it to give me gains NOW.. but when/or if i tune it would help.

but yeah got my answer
sweeeet as :D

at 1st I thought 62mm an overkill for a b16a esp when the b16b came out with a 60mm TB from memory.

I was told the driveability down low with the larger TB has a lot to do with the tuning; many simply whack a bigger TB on and hope for the best without a tune.

Just got my car ( EG ) back from the East today with an ITR 62mm TB on my B16A w/ dc2r cams+IM. Very impressed how it pulls all the way to 8500rpm (8700rpm cut) and it's drivability down low, from standing start as well as going up a hill in top gear under 2000rpm. Dynodave certainly knows his stuff when it comes to not only tuning but parts specification.

Definately faster everywhere by a clear margin than our stock aust spec dc2r.

nice..

thanks for input dude.

wel lets hope it doesnt change too much without a tune aye!

i beleive the larger throttle body wont actually increase power, but will give the impression of power gains.

i mean, to acheive 70% power you will only have to put your foot down 60%. I say this as i was reading into this same subject, but rather boring out my b18c7 TB. There was quite a discussion on this.

can anyone shed some light on this?

without a tune you will not make more power.
The Throttlebody lets a certain amount of air in. Unless you can get more fuel and ingnition timing to it the extra air is not gonna make any power, but could actually loose you more power.

Comes down to basic combustion. If you put too much air you will blow out a flame, but with more fuel you need more air. Hope i explained it right
