Been looking to get a set of TWM ITBs for my LS/VTEC coupe, which is my main source of transportation, and i was wondering if any of you daily drive ITBS and if so what precautions do you take? Filters, Screens, Custom manifolds, or just be straight gangsta and just got them naked.

Also, a buddy of mine is looking to get a set as well for his 00 civic si, since we can get them for a better price for 2 locally. Yet he has basically a stock motor, he does have a DTR header, apexi catback, LSD tranny, clutch with flywheel, and a set of ITR cams he might throw in if he decides to.

My question is, will he benefit from them, the ITBS do come with 310cc injectors, so i'm wondering if it will hurt him performance wise or actually notice somewhat of a difference.
thanks in advance

 

bump

 

no bumping

 

Alot of people I know who have ITB's have little filters on them when driving on the street.

Do you really need ITB's, though? Have you researched the proper size for your setup? There is such a thing as too big of an ITB.

For a street car, I would much rather have the peace of mind that comes with a plenum-style intake with a single TB.

 

drove on my diy for a year , not a problem drive-ability was great if not better then stock (much more responceive) my diy pissed me off at times but it was my own falut.

even got 25mpg+/- on the hiway

 

thats good to hear, what was your setup?

 

I daily mine, no filters but i change the oil frequently. Throttle response is much better than a manifold but sticking throttle gets irritating. Stand alone fuel management tuned by tps takes care of that though.

gsxr1000 itbs spaced out on a custom flange/runners


at tthe time it was a f20b in my 95 accord , i sold them to go bigger but it hasnt funded up yet lol .

it was pretty much stock . but still made a noticeable difference

 

You can make equal to, if not more power (area under the curve & peak) with a properly sized intake manifold and tb. FYI.

You will need some sort of tuning solution that has full resolution tables, hopefully one that has the option for alpha-n tables or a mix of TPS/MAP. Crome Pro is cheap and works great. We've also run PowerFC on ITB's and they run fine.

However, keep in mind that TWM's are not ready to go on the car 'out of the box'. You will need a second throttle return spring to help with throttle stick, and you will need to tap each runner to feed a separate vacuum manifold to run your MAP sensor off of.

FWIW, Jenvey ITB's will make more power everywhere compared to TWM's, even with 2mm smaller plates.

 

You can buy twm's with a vacuum accumulator which eliminates the need to build one or tap anything. It works fine on my car but i remember hearing about it causing a problem on car at rage/hookups. I installed them right out of the box and fired it up on a stock ecu no problem. but thats me, maybe i'm just lucky.

 

itb are the ****, i have a setup. pmed

The problem lies with the integrated accumulator. The MAP signals are distorted by the closest runner. Night and day difference when switching to a separate log/manifold. Had to do this to three different setups using the new TWM's.

its just a better design. they design it more tailored to the head and engine than twm does. twm just uses a basic straight runner. if you compare the jenveys to twms, from both pr3(b16/type r head designation right?) heads and p72 heads, the p72 manifold angle and runners are different than the pr3 from jenvey, and the twm is the same just different flange. jenvey puts more thought into their r&d is how i see it. and no problems sticking with traditional standalone tbs vs cast in tbs in the twms with the linkage contraption on my twms.

 

aight so im bout to put my TWM itb setup on my car so will i need to get it tuned or can it run fine on the stock ecu. plus its my daily driver

 

thats a no go for stock ecu .

managment is a MUST with itbs , its so different then a manifold in the way it acts. your car will flood , foul plugs and **** you off . if it even starts.

get it tuned

 

daily driver with toda itb's here.....

 

well i have the hondata s200, can anybody tune it around my way. richmond, va

does s200 have alpha-n or tps tuning maps? it didn't the last time i checked, so that'll suck.....

you'll need crome, neptune, aem ems, or s300 to get those itb's to their potential.....!

x2

Since you already have the S200, Hondata might give you an upgrade for cheap. Otherwise, Crome is free.

 

Jenvey ITBs w/ AEM....idles,drives like stock
